Calendly

Summary of Important Changes

1. Reorganized terms framework

• The introductory page is substantially rewritten to direct users to different documents based on their user type, including:
• Overview and Definitions
• Customer Terms
• Participant Terms
• Industry-Specific Supplemental Terms
• Beta Terms
• Data Processing Addendum
• Privacy Notice and regional/children’s privacy notices
• Acceptable Use Policy and other policies
• The new structure makes the applicable terms more dependent on whether the user is a Customer, Participant, or Visitor.

Risk: Users may be subject to multiple linked documents, and it may be difficult to determine which provisions govern in the event of inconsistency.

2. Expanded and changed user classifications

• A Customer is now generally an individual with a registered Calendly account or an entity that purchases Calendly licenses for use with email domains it owns, controls, manages, or has authority to bind.
• Authorized Users are expressly defined to include an entity’s employees, consultants, contractors, and agents who are authorized to use the Services and for whom access has been purchased.
• A Participant is generally someone using the Services through a Customer or Authorized User, without their own registered Calendly account.
• A Visitor is someone without a registered account who is not accessing Services made available by a Customer, such as someone merely browsing the Website.

Risk: Organizations may assume responsibility for a broader group of users associated with their domains, including contractors and other agents. Individuals with accounts may be treated as Customers rather than Participants, potentially exposing them to more extensive Customer Terms.

3. Priority of MSA and other terms

• If a Customer has a current, valid MSA with Calendly, the MSA governs and controls.
• Customers without an MSA are subject to the Customer Terms and Conditions, Data Processing Addendum, Acceptable Use Policy, Privacy Notice, and applicable supplemental terms.
• Participants and Visitors are assigned separate terms, while users with accounts are directed to the Customer Terms.

Risk: The applicable contract may vary depending on account status and contractual arrangements, creating uncertainty regarding liability, dispute resolution, data rights, and confidentiality obligations.

4. Changes to modification and acceptance provisions

• The prior language distinguished material changes, for which advance notice would be provided, from other changes effective upon publication.
• The revised language states that material revisions become effective on the date stated in the notice and other changes become effective when published.
• Continued access or use after the effective date constitutes acceptance. Users who disagree must stop using the Services.

Risk: Continued use may create acceptance of revised terms without a separately signed amendment. Customers should monitor the linked terms and preserve historical versions.

5. Expanded investigation and disclosure rights

• Calendly may investigate complaints or suspected violations and take actions including suspension or cancellation of accounts.
• New language expressly permits reporting suspected unlawful activity to law enforcement, regulators, or other third parties and disclosing information related to an account.
• The listed information may include names, email addresses, usage history, posted or solicited materials, IP addresses, traffic information, Customer Data, and Personal Data covered by the Data Processing Addendum or Privacy Notice.
• Users must promptly report unauthorized or illegal access or use to legal@calendly.com.

Risk: Calendly’s express disclosure rights are broader and may permit sharing account- and usage-related information with authorities or third parties in appropriate circumstances.

6. AI model training

• No express provision addressing the use of Customer Data, Personal Data, or other user content to train, fine-tune, or improve AI models appears in this diff.
• The additions concerning “Customer Data” and “Personal Data” relate to investigations, disclosures, and privacy/data-processing documents—not AI training.
• Any AI-training rights or restrictions would need to be reviewed in the Customer Terms, Data Processing Addendum, Privacy Notice, or a separate AI/data-use policy.

Summary

The diff states only that approximately 324 words were removed from the document. It does not identify which clauses, definitions, or obligations were deleted.

Key Legal Implications

Because the deleted text is not provided, it is not possible to determine whether the changes affect:

• Customer or provider obligations
• Liability, indemnification, warranties, or limitations of liability
• Confidentiality or data-security requirements
• Term, termination, renewal, or payment terms
• Intellectual-property ownership or licensing
• Audit, compliance, or regulatory rights
• Dispute resolution or governing law
• Changes to service functionality or commercial terms

The removal of legal text could be significant even if no replacement language appears, particularly if it eliminates protections, conditions, or limitations that previously applied.

AI Training and Customer Data

The available diff contains no identifiable language concerning the use of customer data to train, fine-tune, evaluate, or improve AI or machine-learning models.

Accordingly, it is not possible to determine whether the amendment:

• Authorizes or prohibits AI training on customer data
• Changes whether customer data may be used for model improvement
• Expands use of data to include prompts, outputs, metadata, or derived data
• Changes data-retention, deletion, anonymization, or aggregation rights
• Grants the provider ownership or licensing rights in customer data or model outputs
• Requires consent, opt-out, or other controls for AI-related processing

Assessment

Risk level: Unable to assess from the supplied diff. The notation “[Removed approximately 324 words from the document]” is a summary, not the actual deleted language. The omitted provisions should be reviewed before concluding that the amendment is neutral or non-substantive.

Information Needed

To perform a reliable legal analysis, provide either:

1. The actual deleted text; or

2. The document’s before-and-after versions, including any surrounding clauses.

Special attention should be given to deleted provisions containing terms such as “train,” “training,” “improve,” “machine learning,” “artificial intelligence,” “models,” “prompts,” “outputs,” “customer data,” “usage data,” “aggregated,” “de-identified,” “retain,” or “license.”

Summary

The provided diff does not include the actual amended language. It only states:

> “Added approximately 324 words to the document”

Accordingly, it is not possible to determine:

• What contractual provisions changed;
• Whether any customer obligations or provider rights were expanded;
• Whether liability, indemnity, confidentiality, security, or termination terms changed; or
• Whether the customer’s data may be used to train, fine-tune, evaluate, or otherwise improve AI models.

AI Training and Data-Use Analysis

No specific language concerning AI, machine learning, model training, data usage, content ownership, anonymization, or service improvement is included in the supplied diff.

The following provisions should be reviewed in the added text, particularly if they appear:

• Training rights: Permission to use customer data, prompts, outputs, usage data, or metadata to train or improve AI models.
• Scope of data: Whether “customer data” includes confidential information, personal data, uploaded files, prompts, or generated outputs.
• Consent mechanism: Whether use is automatic, opt-out, or opt-in.
• De-identification: Whether data must be anonymized or de-identified before model training, and whether the contract defines that standard.
• Retention: How long data may be retained for training, evaluation, or product development.
• Third-party sharing: Whether data may be disclosed to affiliates, vendors, cloud providers, or model-development partners.
• Model ownership and outputs: Whether the provider owns models trained using customer data and whether customer content may be reflected in future outputs.
• Confidentiality and security: Whether training use is consistent with confidentiality obligations and applicable data-protection laws.
• Deletion and withdrawal: Whether the customer can require deletion or prevent future use after termination or an opt-out request.

Required Information

Please provide the full diff, including the approximately 324 added words and any surrounding deleted or replacement language. Without the actual text, no reliable legal risk assessment or determination of AI-training rights can be made.

Summary of Identified Changes

Scope of the Diff

• The diff states only that approximately 324 words were removed.
• The actual deleted language is not provided.
• Because the removed text is unavailable, it is not possible to determine:
• Which contractual rights or obligations changed;
• Whether liability, confidentiality, intellectual property, security, or termination provisions were affected;
• Whether customer data may now be used differently; or
• Whether any restrictions on artificial intelligence or model training were deleted.

AI Training and Customer Data

• No definitive change can be identified regarding the use of customer data to train AI models.
• However, if the deleted language addressed any of the following, its removal could materially increase risk:
• A prohibition or limitation on using customer data to train, fine-tune, or improve AI models;
• A requirement to obtain the customer’s consent before such use;
• Restrictions on using customer content for product development or analytics;
• Commitments to anonymize, de-identify, or aggregate customer data;
• Limits on sharing data with AI vendors or subprocessors;
• Requirements to delete customer data from training datasets or models; or
• Ownership or licensing terms covering prompts, outputs, or model improvements.

Potential Legal Significance

Deleting approximately 324 words could remove important protections, but the effect cannot be assessed from the deletion count alone. The deletion may:

• Broaden the provider’s permitted uses of data by removing express restrictions;
• Eliminate customer warranties, indemnities, or remedies;
• Reduce transparency regarding subprocessors or data transfers;
• Remove security, confidentiality, or deletion commitments; or
• Simplify the agreement without changing substantive rights.

Information Needed

To perform a reliable legal review, provide the actual deleted text and, if applicable, the surrounding unchanged provisions. Particular attention should be given to deleted language containing terms such as:

• “train,” “fine-tune,” “improve,” or “develop”;
• “artificial intelligence,” “machine learning,” or “models”;
• “customer data,” “content,” or “inputs”;
• “aggregate,” “anonymize,” or “de-identify”; and
• “license,” “consent,” “ownership,” “retain,” or “delete.”

Summary

The supplied diff does not include the actual amended legal language. It only states:

> “Added approximately 324 words to the document”

Accordingly, it is not possible to determine:

• What provisions were added, deleted, or replaced;
• Whether customer data may be used to train, fine-tune, test, or improve AI models;
• Whether such use is permitted by default or requires customer consent;
• Whether data is anonymized, aggregated, de-identified, or retained;
• Whether the provider may share data with affiliates, vendors, or model providers;
• Whether the customer can opt out or request deletion;
• Any changes to confidentiality, ownership, security, indemnity, or liability protections.

AI-Training Risk Assessment

No conclusion can be reached regarding AI-model training because the substantive additions are missing. The phrase “Added approximately 324 words” does not identify whether the new language:

• Authorizes training on customer prompts, inputs, outputs, files, or usage data;
• Limits training to de-identified or aggregated information;
• Allows human review or use for service improvement;
• Grants the provider ownership or broad usage rights;
• Applies retroactively to previously collected data;
• Permits retention after termination; or
• Creates an opt-out mechanism or imposes additional customer obligations.

Information Needed

Please provide the full redline or the exact 324 words, using the stated notation:

• Additions in {braces};
• Deletions in [brackets]; and
• Replacements as []{}.

Once the substantive text is provided, the changes can be analyzed for legal effect, including specific risks concerning AI training, data ownership, confidentiality, retention, security, third-party disclosure, and liability.

Key Changes and Risks

1. Major restructuring of the terms framework

• The prior introductory material appears to have been replaced with a new “Welcome! Effective Date: June 1, 2026” framework.
• The new structure directs users to determine whether they are a Customer, Participant, or Visitor, then review the terms applicable to that category.
• The terms now expressly state that the framework applies to “all users, regardless of user type.”
• The new language is substantially more detailed and incorporates multiple documents by reference, including the Customer Terms, Participant Terms, Privacy Notice, Data Processing Addendum, Acceptable Use Policy, and potentially industry-specific terms.

Risk: Users may be bound by several linked documents without all terms appearing in one agreement. There may also be uncertainty about which terms control if a person falls into more than one category.

2. New or revised user classifications

• A Customer includes an individual with a registered account or an entity that purchased licenses for authorized users.
• A Participant is generally someone who accesses the Services through a Customer’s invitation, scheduling link, or similar interaction and does not have their own registered account.
• A Visitor is someone without a registered account who is not accessing Services made available by a Customer.

Risk: The classification rules may affect which privacy, liability, dispute-resolution, and data-use terms apply. The distinction between a Participant and Visitor could be fact-dependent and difficult for users to determine.

3. MSA priority appears narrowed

• The previous language stated that a current, valid MSA would govern and control over the online terms.
• The replacement appears to say that users enter the online terms voluntarily and not in reliance on representations outside the Terms, while retaining some reference to an MSA for Customers.

Risk: The revised wording could create ambiguity about whether an MSA controls in all conflicts, particularly for non-Customer users or users associated with an MSA customer.

4. Broader unilateral amendment and clickwrap-by-use provisions

• Calendly may change the Terms or policies “in whole or in part.”
• Material changes receive commercially reasonable advance notice; other changes become effective when published.
• Continued access or use after the effective date constitutes acceptance.
• Users who disagree must stop using the Services.

Risk: This permits changes to incorporated policies without an express signature or affirmative acceptance. The “material” versus “other” change distinction is not defined.

5. Expanded investigations, suspension, and disclosure rights

Calendly may investigate complaints or reported violations and take actions including:

• Suspending or canceling accounts;
• Reporting suspected unlawful activity; and
• Disclosing account and usage information to law enforcement, regulators, or other third parties.

The listed information includes names, email addresses, usage history, posted or solicited materials, IP addresses, traffic information, Customer Data, and Personal Data.

Risk: This is a broad disclosure authorization, with no express requirement for legal process, user notice, necessity, or proportionality. It may create compliance, confidentiality, and customer-notification concerns.

6. AI-model training

• The diff contains no express provision authorizing or prohibiting the use of Customer Data, Participant data, or Personal Data to train, fine-tune, or improve AI models.
• The references to “Customer Data” and “Personal Data” occur in the investigation and disclosure context, not in an AI-training clause.
• Any AI-training permissions would therefore need to be located in the referenced Customer Terms, Data Processing Addendum, Privacy Notice, or another incorporated policy.

Risk: The absence of an express restriction does not confirm that data will not be used for AI training. Customers should review all incorporated documents for terms allowing service improvement, analytics, model training, de-identification, aggregation, or use of prompts/content.

Diff Analysis

Summary

The provided diff does not include the actual contractual language. It only states that approximately 324 words were added. Without the added, deleted, or replacement text, it is not possible to determine the legal or commercial impact of the changes.

AI Training and Customer Data

No conclusions can be drawn about whether the agreement now permits or restricts the use of customer data to train AI models. The relevant language would need to be reviewed for provisions addressing:

• Whether customer data, prompts, inputs, outputs, or usage data may be used to train, fine-tune, improve, or evaluate AI models.
• Whether training is permitted by default or requires the customer’s express consent.
• Whether the permission applies to identifiable data, de-identified data, aggregated data, or metadata.
• Whether the provider may use data to train its general-purpose models or only models dedicated to the customer.
• Whether the customer can opt out, withdraw consent, or require deletion of training data.
• Whether subcontractors, affiliates, or third-party AI providers may use the data for training.
• Confidentiality, security, retention, and data-deletion obligations relating to training datasets.
• Ownership and licensing rights in customer data, derivative data, model improvements, and outputs.

Other Legal Risks That Cannot Yet Be Assessed

The missing text may also affect:

• Data protection and privacy compliance.
• Confidentiality and permitted-use restrictions.
• Intellectual property ownership and licensing.
• Liability, indemnification, and warranties.
• Data retention and deletion.
• Audit, transparency, and regulatory rights.
• Use of customer data for analytics, benchmarking, or product improvement.
• Changes to termination rights or post-termination data use.

Required Information

Please provide the actual diff, including the text within {}, [], and []{}. The stated word-count increase alone is insufficient to identify the changes or assess new risks.

Key Changes and Risks

1. New user classification framework

The terms replace the prior general overview with a detailed framework distinguishing:

• Customers — individuals or entities with registered accounts or purchased licenses;
• Participants — people using the Services through a Customer’s invitation, scheduling link, or similar interaction, without their own registered account; and
• Visitors — people without a registered account who are merely browsing the Website and are not accessing Services made available by a Customer.

The terms and policies applicable to a user now depend on that classification. This may create uncertainty where a person fits more than one category—for example, an individual with a registered account who also joins another Customer’s meeting.

2. Broader application of website and service terms

The revised language states that the applicable terms govern access to and use of both the Services and the Website, depending on the user type. Visitors are expressly made subject to terms and policies provided through links on the page.

Risk: Users may be bound by policies incorporated by hyperlink, including policies they may not have specifically reviewed. The structure may also make it harder to determine which terms apply in mixed-use situations.

3. Changes to amendment and acceptance mechanics

The revised terms provide that:

• Calendly may change the Terms or policies in whole or in part;
• Material changes will receive commercially reasonable advance notice;
• Material revisions become effective on the date stated in the notice;
• Other changes become effective when published; and
• Continued access or use after the effective date constitutes acceptance.

Users who disagree must stop using the Services.

Risk: This creates a potentially broad unilateral-change mechanism, including for non-material changes that may become effective immediately upon publication. Continued use is treated as acceptance without requiring affirmative consent.

The prior language more expressly stated that a current and valid MSA governs and controls. The revised wording should be checked carefully to confirm whether that MSA priority remains fully preserved.

4. Expanded investigation and disclosure rights

Calendly may investigate complaints or reported violations and take actions including suspension or cancellation of an account and reporting suspected unlawful activity. The revised wording expressly permits disclosure to law enforcement, regulators, or other third parties of information such as:

• Names and email addresses;
• Usage history;
• Posted or solicited materials;
• IP addresses and traffic information;
• Customer Data; and
• Personal Data covered by the Data Processing Addendum or Privacy Notice.

Risk: The disclosure authorization is broad and is not limited to lawfully compelled disclosures or narrowly defined circumstances.

5. Security incident notification

Users must promptly notify Calendly of unauthorized or illegal access or use of the Services.

6. Third-party website disclaimer

The revised Website section more clearly disclaims affiliation, endorsement, warranties, and responsibility for third-party websites, including their privacy practices and use or control of information.

7. AI-model training

No express change addressing AI training, model development, or use of Customer Data to train AI models appears in this diff. The expanded references to “Customer Data” and “Personal Data” concern investigations and disclosures, not AI training. The separate Customer Terms, Privacy Notice, and Data Processing Addendum should nevertheless be reviewed for any AI-use provisions incorporated by reference or linked from this page.

Summary of Important Changes

1. User categories and applicable terms

• The prior “Customer,” “Participant,” and “Visitor” framework has been reorganized and expanded.
• A Customer is now generally an individual with a registered Calendly account, or an entity that has purchased Calendly licenses for its authorized users.
• The revised language more clearly defines:
• Entities and their authority over email domains;
• Authorized Users, including employees, consultants, contractors, and agents; and
• Participants as people using Calendly through a Customer’s invitation, scheduling link, or authorized user.
• Visitors are described as people without registered accounts who are merely browsing the website or using services made available by a Customer.

Risk

The new definitions may cause an organization or individual to be classified differently than before. That classification determines which terms, privacy documents, and liability provisions apply. Organizations should confirm that users with company email domains are properly treated as authorized users or participants.

2. Contract hierarchy and MSA precedence

• The revised terms state that a Customer’s access and use are governed by the Customer Terms and Conditions and, where applicable, the Customer’s valid MSA.
• If there is a current and valid MSA, it controls over the online Customer Terms and Conditions.
• Customers without an MSA are also made subject to the Data Processing Addendum, Acceptable Use Policy, Privacy Notice, and applicable supplemental terms.

Risk

The hierarchy is clearer, but customers should review their MSA and incorporated online documents together. Important obligations may exist outside the signed agreement, particularly in the Data Processing Addendum, Privacy Notice, and supplemental terms.

3. Acceptance and changes to terms

• Continued use after the effective date of revised terms constitutes acceptance.
• Material changes receive commercially reasonable advance notice.
• Other changes become effective when published.
• Users who disagree must stop using the Services.

Risk

The update preserves a broad “browsewrap” or continued-use acceptance mechanism. Non-material changes may take effect without individualized notice, creating compliance and operational monitoring obligations for customers.

4. Investigations, suspension, and disclosures

• Calendly’s investigation rights are restated and broadened to permit actions including:
• Suspending or canceling an account;
• Reporting suspected unlawful activity to law enforcement, regulators, or other third parties; and
• Disclosing information related to the account or Services as necessary or appropriate.

Risk

The language gives Calendly substantial discretion to investigate and disclose account-related information. Customers should assess whether their incident-response, confidentiality, and regulatory obligations are compatible with these provisions.

5. Data use and AI-model training

• The diff adds or restates references to:
• Customer Data;
• Personal Data;
• Names, email addresses, usage history, posted or solicited materials;
• IP addresses and traffic information; and
• The Data Processing Addendum and Privacy Notice.
• No express provision in this diff authorizes, prohibits, or changes the use of Customer Data or Personal Data to train AI models.

Risk / action item

Because the diff repeatedly incorporates the Data Processing Addendum and Privacy Notice, any AI-training rights may exist in those documents rather than in this overview. Those documents should be reviewed separately for provisions concerning model training, service improvement, de-identification, retention, subprocessors, and opt-out rights.

Summary

The diff indicates that approximately 324 words were removed, but does not identify which provisions were deleted.

Key Legal Impact

Because the deleted language is not provided, it is not possible to determine reliably:

• Whether the customer’s data may now be used to train, fine-tune, or improve AI models.
• Whether the provider retained rights to use customer content for analytics, product development, or service improvement.
• Whether confidentiality, data-security, or privacy obligations were reduced.
• Whether customer ownership or license restrictions were changed.
• Whether data-retention, deletion, or return obligations were removed.
• Whether liability, indemnification, audit, or regulatory-compliance protections were narrowed.

AI Training and Data Use

No specific change concerning AI-model training can be confirmed from the available diff. However, deletion of approximately 324 words could be significant if the removed text addressed:

• Use of customer prompts, inputs, outputs, files, or other content to train or improve models.
• Whether such use required the customer’s consent or opt-in approval.
• Whether data would be anonymized, aggregated, or de-identified before use.
• Whether human reviewers or service providers could access customer data.
• Whether the customer could opt out of model training.
• Restrictions on using confidential, personal, regulated, or sensitive information.

If language restricting training or secondary use was deleted, the customer may face a broader implied or express right for the provider to use its data. Conversely, if a provider authorization was deleted, the provider’s ability to use customer data may have narrowed.

Risk Assessment

The principal risk is uncertainty. A redline showing only that words were removed is insufficient to assess the legal effect. The deleted provisions should be reviewed in full, especially any sections titled:

• Data Use or Customer Content
• Artificial Intelligence or Machine Learning
• Confidentiality
• Privacy and Security
• Intellectual Property
• Data Retention and Deletion
• Service Improvement

Recommended Next Step

Obtain the actual 324 deleted words and compare them with the final agreement. Do not assume that deletion is favorable: removing a restriction, consent requirement, confidentiality obligation, or opt-out right could materially increase the customer’s exposure.

Summary of Important Changes

1. Major restructuring of the terms framework

• The introductory material is substantially rewritten and reorganized into linked categories, including:
• Overview, Definitions, Customer Terms, Participant Terms, and Conditions
• Data Processing Addendum, Privacy Notice, CCPA and children’s privacy notices
• Acceptable Use Policy and other supplemental policies
• The terms now direct users to determine their user category first and then review the applicable terms.
• This creates a more structured framework but increases the risk that users may not realize which linked documents apply to them or that multiple documents govern their use.

2. New and revised user classifications

The prior “Customer,” “Participant,” and “Visitor” definitions are replaced with more detailed classifications:

• Customer: Generally an individual with a registered Calendly account, or an entity that purchased Calendly licenses for use with domains it owns, controls, manages, or has authority to bind.
• Authorized Users: Expanded to include an entity’s employees, consultants, contractors, and agents who are authorized to use the services and for whom access has been purchased.
• Participant: A non-Customer who accesses or uses the services through an invitation, scheduling link, or interaction initiated by a Customer or Authorized User, without having their own registered account.
• Visitor: A person without a registered account who is merely browsing the website and is not accessing services made available by a Customer.

Risk: The classification determines which terms apply, potentially affecting dispute rights, arbitration, privacy obligations, and responsibility for use. The entity-based definition may also classify users based on email-domain ownership or control, even where the user’s understanding differs.

3. Allocation of responsibility and incorporation of terms

• Customers are made responsible for individuals using the services through their organization’s email domains.
• Authorized Users may include a broad range of personnel and agents.
• Customer access is expressly subject to the Customer Terms, related conditions, and any valid MSA. A valid MSA controls where applicable.
• Non-Customers are directed to the Participant Terms or Visitor terms, as applicable.

Risk: Organizations may bear responsibility for a broader group of users than before, including contractors and consultants.

4. Changes to amendment and acceptance provisions

• The prior language distinguishing material changes from other changes is replaced with a general process:
• Material changes receive commercially reasonable advance notice.
• Other changes become effective when published.
• Continued use after the effective date constitutes acceptance.
• Users who disagree may no longer use the services.

Risk: Non-material terms can apparently change without advance notice, and continued use creates contractual acceptance.

5. Investigations and information disclosure

• Calendly receives broader express authority to investigate suspected violations and take action, including suspension or cancellation of accounts.
• It may report suspected unlawful activity to law enforcement, regulators, or third parties and disclose related account or service information.
• The listed information includes names, email addresses, usage history, posted or solicited materials, IP addresses, traffic information, Customer Data, and Personal Data under the Data Processing Addendum or Privacy Notice.
• Users must promptly report unauthorized or illegal access or use to Calendly.

6. AI-model training

• No express change in this diff authorizes or prohibits using Customer Data, Personal Data, or service content to train AI models.
• The revised language references Customer Data and Personal Data and permits disclosure in connection with investigations, but it does not mention artificial intelligence, machine learning, model training, model improvement, or similar uses.
• Any AI-training rights or restrictions must therefore be checked in the separately incorporated Customer Terms, Data Processing Addendum, Privacy Notice, or other applicable policies.

Summary of Important Changes

1. Expanded user classifications

The terms now distinguish among:

• Customers: Individuals with registered Calendly accounts, or entities that purchase Calendly licenses.
• Participants: Individuals without registered accounts who access or use the Services through a Customer’s invitation, scheduling link, or other Customer-initiated interaction.
• Visitors: Individuals without registered accounts who are merely browsing the Website and are not accessing Services made available by a Customer.

This replaces the prior, broader treatment of account holders, entities, Authorized Users, and website visitors. Users should confirm which category applies because different terms and policies may govern each category.

2. New terms for Participants and Visitors

Participants are expressly made subject to separate Participant Terms and Conditions. Visitors are subject to the terms and policies made available through links on the applicable page.

The revised structure may create uncertainty about which terms apply where a person moves between categories—for example, by creating an account, accepting an invitation, or using a scheduling link.

3. MSA and incorporated policies

For Customers with a valid MSA, the MSA governs and controls. Otherwise, the Customer Terms and Conditions apply together with the Data Processing Addendum, Acceptable Use Policy, Privacy Notice, and applicable industry-specific supplemental terms.

The revised language also expressly highlights dispute-resolution provisions, including arbitration and a class-action waiver, and states that users acknowledge entering into the terms voluntarily and not relying on representations outside the terms.

4. Unilateral changes and acceptance by continued use

Calendly may change the terms or policies in whole or in part. Material changes will generally receive commercially reasonable advance notice; other changes become effective when published. Continued access or use after the effective date constitutes acceptance.

Users who disagree may no longer use the Services, leaving continued use as a form of acceptance without requiring a separate affirmative click.

5. Expanded investigation and disclosure rights

Calendly may investigate complaints or suspected violations and take actions it considers appropriate, including:

• Suspending or canceling an account;
• Reporting suspected unlawful activity to law enforcement, regulators, or other third parties; and
• Disclosing account or usage information.

The listed information includes names, email addresses, usage history, posted or solicited materials, IP addresses, traffic information, Customer Data, and Personal Data, as described under the DPA or Privacy Notice. This is a significant expansion or clarification of Calendly’s express disclosure rights and may increase privacy, confidentiality, and regulatory risk for Customers and users.

6. AI-model training

No express change concerning use of Customer Data to train AI models appears in this diff. The revised language does, however, broaden or clarify the categories of Customer Data and Personal Data that may be disclosed during investigations. Any AI-training rights must therefore be checked in the separate Customer Terms, DPA, Privacy Notice, or AI-specific terms.

7. Third-party websites

The revised Website provisions emphasize that third-party links may expose users to third parties’ own data practices, disclaim Calendly responsibility, and place use of those sites at the user’s own risk.

The publisher records this document as revised on this date (“Effective Date: June 1, 2026”).

Summary

The provided diff states only that approximately 278 words were removed from the document. It does not identify:

• Which clauses were deleted;
• Whether the deletions were replaced with different language;
• Whether any definitions, obligations, rights, or limitations were affected; or
• Whether the removed text addressed customer data or AI model training.

AI Training and Customer Data

No conclusions can be drawn from the information provided about changes to:

• Whether the provider may use customer data to train, fine-tune, or improve AI models;
• Whether customer data may be used for product development, analytics, or benchmarking;
• Whether prompts, inputs, outputs, or metadata are retained;
• Whether data is anonymized, aggregated, or shared with affiliates or subprocessors;
• Whether the customer can opt out of model training; or
• Whether any training-related rights apply retroactively to previously submitted data.

Because the deleted language is not included, removal of the words could potentially have expanded or narrowed the provider’s rights, depending on what was removed and whether another provision now controls.

Key Risk

The principal risk is lack of visibility into the deleted terms. If the removed text contained restrictions on data use, confidentiality, deletion, security, or AI training, those protections may no longer apply. Conversely, if it contained the provider’s authorization to use data, its removal may reduce that authorization.

Information Needed

To perform a meaningful legal analysis, provide either:

1. The full document before and after the change;

2. The actual deleted text; or

3. A redline showing the deleted language, including the surrounding section headings and replacement text, if any.
