Privacy Policy

This policy was published on June 8, 2026 with an effective date of July 8, 2026.

Anthropic is an AI safety and research company working to build reliable, interpretable, and steerable AI systems.

This Privacy Policy explains how we collect, use, disclose, and process your personal data when you use our website, Claude.ai, or other Anthropic products and services (the “Services”). This Privacy Policy does not apply to content that we process on behalf of customers of our business offerings, such as our Enterprise accounts. Our use of that data is governed by our customer agreements covering access to and use of those offerings.

Please see our Non-User Privacy Policy for information on how our large language models are ‘trained’ and how personal data obtained from third party sources, including where others may submit personal data when using our services, may be used when developing or delivering our products and services.

This Privacy Policy also describes your privacy rights. More information about your rights, and how to exercise them, is set out in Section 4 (“Rights and Choices”).

If you are located in Canada, Brazil, or the Republic of Korea, please read the relevant Regional Supplemental Disclosure which applies to you.

If you are located in Washington or a state with similar consumer health data laws, please read our Consumer Health Data Privacy Policy which applies to you if you integrate third party health applications with Claude.

1. Collection of Personal Data

We collect the following categories of personal data:

Personal data you provide to us directly

• Identity and Contact Data: Anthropic collects identifiers, including your name, email address, and phone number when you sign up for an Anthropic account, or to receive information on our Services. We may also collect or generate indirect identifiers (e.g., “USER12345”).
• Payment Information: We shall collect your payment information if you choose to purchase access to Anthropic’s Services.
• Inputs and Outputs: You are able to interact with our Services in a variety of formats, including but not limited to chat, coding, agentic sessions (where Claude performs multi-step tasks or takes actions on your behalf), and connected services. The content you submit to the Services through these interactions, including via third-party applications, services, and content you choose to upload, integrate or interact with using our Services, are your “Inputs”. Inputs generate responses and actions (“Outputs”). If you include personal data or reference external content in your Inputs, we will collect that information and it may be reproduced in your Outputs. Depending on the permissions you grant Claude, some Outputs may result in actions with effects outside the Services, such as sending communications, modifying files, or interacting with third-party services on your behalf.
• Feedback on your use of our Services: We appreciate feedback, including ideas and suggestions for improvement or rating an Output in response to an Input ("Feedback"). If you rate an Output in response to an Input—for example, by using the thumbs up/thumbs down icon—we may store the entire related conversation as part of your Feedback. You can learn more about how we use Feedback here.
• Study Participation Data: If you participate in Anthropic research studies, surveys, or interviews (for example our Anthropic Interviewer), we collect the responses you provide, associated account data, and related Technical Information. We may combine this data with other data from your account for aggregated analysis.
• Communication Information: If you communicate with us, including via our chatbot on our Help site, we collect your name, contact information, and the contents of any messages you send.
• Verification Data: In certain circumstances, we may ask you to verify your age or identity. If you choose to do so, data we will collect includes, depending on the method: an image of your government-issued identity document and the information appearing on it (such as your ID number and date of birth); your image in photo or video form, facial geometry templates (which may be considered ‘biometric data’ in some jurisdictions); and the result of the verification (for example, whether your age meets the applicable threshold).

When you provide Inputs—including by uploading files, granting Claude access to third-party services, or instructing Claude to retrieve or act on information—you are responsible for ensuring you have the necessary rights, permissions, or authority to do so.

Personal data we receive automatically from your use of the Services

When you use the Services, we also receive certain technical data automatically (described below, collectively “Technical Information”). This includes:

• Device and Connection Information: Consistent with your device or browser permissions, your device or browser automatically sends us information about when and how you install, access, or use our Services. This includes information such as your device type, operating system information, browser information and web page referers, mobile network, connection information, mobile operator or internet service provider (ISP), time zone setting, IP address (including information about the location of the device derived from your IP address), identifiers (including device or advertising identifiers, probabilistic identifiers, and other unique personal or online identifiers), and device location.
• Usage Information: We collect information about your use of the Services, such as the dates and times of access, browsing history, search, information about the links you click and about third-party applications, services, and content you integrate or interact with, pages you view, and other information about how you use the Services, and technology on the devices you use to access the Services.
• Log and Troubleshooting Information: We collect information about how our Services are performing when you use them. This information includes log files. If you or your device experiences an error, we may collect information about the error, the time the error occurred, the feature being used, the state of the application when the error occurred, and any communications or content provided at the time the error occurred.
• Cookies & Similar Technologies: We and our service providers use cookies, scripts, or similar technologies (“Cookies”) to manage the Services and to collect information about you and your use of the Services. These technologies help us to recognize you, customize or personalize your experience, market additional products or services to you, and analyze the use of our Services to make them safer and more useful to you. For more details about how we use these technologies, and your opt-out controls and other options, please visit our Cookie Policy.

Personal data we collect or receive to train our models

Anthropic obtains personal data from third party sources in order to train our models. Specifically, we train our models using data from the following sources:

• Publicly available information via the Internet
• Datasets that we obtain through commercial agreements with third party businesses
• Data that our users or crowd workers provide, including Inputs and Outputs from our Services (unless users opt out)
• Feedback that users explicitly provide about our Services
• Materials flagged for safety, security, or policy review
• Data that we generate internally

For more information about how we collect and use personal data to develop our language models that power our Services, the steps we take to minimize the privacy impact on individuals through the training process, and your choices with respect to that information, please see our separate Non-User Privacy Policy.

2. Uses of Personal Data Permitted Under Applicable Data Protection Laws

We use your personal data for the following purposes:

• To provide, maintain and facilitate any products and services offered to you with respect to your Anthropic account, which are governed by our Terms of Service;
• To provide, maintain and facilitate optional services and features that enhance platform functionality and user experience;
• To provide you with service updates, communications, and to provide tailored recommendations about our Services that may be of interest to you;
• To create and administer your Anthropic account;
• To facilitate payments for products and services provided by Anthropic;
• To prevent and investigate fraud, abuse, and violations of our Usage Policy, unlawful or criminal activity, unauthorized access to or use of personal data or Anthropic systems and networks, to protect our rights and the rights of others, to protect your safety or that of any other person, and to meet legal, governmental and institutional policy obligations;
• To investigate and resolve disputes;
• To investigate and resolve security issues;
• To debug and to identify and repair errors that impair existing functionality;
• To improve the Services and conduct research, including training our models and conducting broader research on AI-related topics such as the societal impacts of AI; and

We may use your Inputs and Outputs to train and improve Anthropic AI models, unless you opt out through your account settings. Even if you opt-out, we will use Inputs and Outputs for model improvement when: (i) your conversations are flagged for safety review to improve our ability to detect harmful content, enforce our policies, or advance AI safety research, or (ii) you've explicitly reported the materials to us (for example via our feedback mechanisms).

Please see Section 10 below for details of our legal bases for processing your personal data.

3. Recipients and Third-Party Data Sources

Anthropic will disclose personal data to, or receive personal data from, the following categories of third parties for the purposes explained in this Policy:

• Affiliates & corporate partners: Anthropic discloses the categories of personal data described above between and among its affiliates and related entities.
• Service providers & business partners: Anthropic may receive and disclose the categories of personal data described above with service providers and business partners for a variety of business purposes, including website and data hosting, ensuring compliance with industry standards, research, auditing, data processing, investigating and resolving safety and security issues, preventing and investigating fraud, abuse, and violations of our Usage Policy, and providing you with the Services.
• Your Organization and Administrator: If you use an email address owned by your employer or another organization, your account may be linked to the organization’s enterprise account with us, as described in our Consumer Terms of Service.

Anthropic may also receive or disclose personal data in the following circumstances:

• As part of a significant corporate event: If Anthropic is involved in a merger, corporate transaction, bankruptcy, or other situation involving the transfer of business assets, Anthropic will receive or disclose your personal data as part of these corporate transactions.
• Third-Party Websites, Integrations, and Services: Our Services allow you to connect to and interact with third-party applications, services, and content (“Third-Party Services”) via the Services and through integrations you enable, such as Connectors, plugins, webhooks, and external APIs. When you connect to or interact with Third-Party Services:
  • Claude may send your Inputs, Outputs, and instructions to Third-Party Services to perform actions on your behalf (such as reading files, sending messages, or retrieving information). The Third-Party Service receives this data directly and processes it according to its own privacy policy.
  • Claude may retrieve content and data from Third-Party Services you interact with. This data becomes part of your Inputs.
  • Some integrations or features may allow Claude to access Third-Party Services on an ongoing basis until you disable the feature or disconnect the integration in your settings.
• Anthropic does not control, and is not responsible for, the data practices of Third-Party Services. Before enabling an integration, granting Claude access to, or instructing Claude to take actions on a Third-Party Service, you should ensure you have the authority to grant such access and that doing so complies with any applicable terms, policies, or confidentiality obligations. Before enabling an integration, you should review the third party's privacy policy. Our Services may also link to third-party websites (such as social media); by following these links, you provide information directly to those third parties. Our linking to, or supporting an integration with, a Third-Party Service does not mean we endorse it or speak for that third party.
• Pursuant to regulatory or legal requirements, safety, rights of others, and to enforce our rights or our terms. We may share personal data with government authorities, law enforcement, or other third parties where, based on the information available to us, we have a good-faith belief that disclosure is reasonably necessary to (i) comply with applicable law, regulation or legal process, including for legal, tax or accounting purposes, or in response to an enforceable governmental request; (ii) prevent serious harm to any person or to property; (iii) detect, prevent, or otherwise address fraud or other illegal activity; or (iv) enforce our terms, or protect the rights, property, security, or safety of Anthropic, our users, or others.
• Research publications: We may publish aggregated, de-identified, or anonymized findings from our research, including research into how our Services are used and AI safety research.
• With an individual's consent: Anthropic will otherwise disclose personal data when an individual gives us permission or directs us to disclose this information, including as a part of our Services.

You can find information about the third parties Anthropic engages to help us process personal data here.

4. Rights and Choices

Depending on where you live and the laws that apply in your country of residence, you may enjoy certain rights regarding your personal data, as described further below. However, please be aware that these rights are limited, and that the processes by which we may need to action your requests regarding our training dataset are complex. We may also decline a request if we have a lawful reason for doing so. That said, we strive to prioritize the protection of personal data, and comply with all applicable privacy laws.

To exercise your rights, you or an authorized agent may submit a request by contacting us. After we receive your request, we may verify it by requesting information sufficient to confirm your identity (e.g. email address, billing details). Where a third party representative submits a request on behalf of a data subject, we require evidence of authorization to act on behalf of the data subject.

We will respond to your request within the period required by the data protection law that applies to you. For example, where the EU GDPR or UK GDPR applies, we will respond within one calendar month of receiving a verifiable request, and where your request is complex or you have made a number of requests within a short timeframe, we may extend that period by up to a further two months. Where another law applies to you and sets a different period, we will respond within that period. You may also have the right to appeal requests that we deny by emailing privacy@anthropic.com. Anthropic will not discriminate based on the exercising of privacy rights you may have. Set out below is a summary of the rights which you may enjoy, depending on the laws that apply in your country of residence.

• Right to know: the right to know what personal data Anthropic processes about you, including the categories of personal data, the categories of sources from which it is collected, the business or commercial purposes for collection, and the categories of third parties to whom we disclose it.
• Access & data portability: the right to request a copy of the personal data Anthropic processes about you, subject to certain exceptions and conditions. In certain cases and subject to applicable law, you have the right to port your information.
• Deletion: the right to request that we delete personal data collected from you when you use our Services, subject to certain exceptions. You also are able to delete individual conversations, which will be removed immediately from your conversation history and automatically deleted from our back-end within 30 days. Learn more here.
• Correction: the right to request that we correct inaccurate personal data Anthropic retains about you, subject to certain exceptions. Please note that we cannot guarantee the factual accuracy of Outputs. If Outputs contain factually inaccurate personal data relating to you, you can submit a correction request and we will make a reasonable effort to correct this information—but due to the technical complexity of our large language models, it may not always be possible for us to do so.
• Objection: the right to object to processing of your personal data, including profiling conducted on grounds of public or legitimate interest. In places where such a right applies, we will no longer process the personal data in case of such objection unless we demonstrate compelling legitimate grounds for the processing which override your interests, rights, and freedoms, or for the establishment, exercise or defense of legal claims. If we use your information for direct marketing, you can object and opt out of future direct marketing messages using the unsubscribe link in such communications.
• Restriction: the right to restrict our processing of your personal data in certain circumstances.
• Withdrawal of consent: Where Anthropic’s processing of your personal data is based on consent, you have the right to withdraw your consent. For example, you can disconnect your health app integration and withdraw your consent in your settings. The withdrawal of consent will not affect the lawfulness of processing based on consent before its withdrawal.
• Automated decision-making: Anthropic does not engage in decision making based solely on automated processing or profiling in a manner which produces a legal effect (i.e., impacts your legal rights) or significantly affects you in a similar way (e.g., significantly affects your financial circumstances or ability to access essential goods or services).
• Sale & targeted Anthropic marketing of its products and services: Anthropic does not “sell” your personal data as that term is defined by applicable laws and regulations. You can opt-out of sharing your personal data for targeted advertising to promote our products and services, and we will honor global privacy controls. To learn more, click here.

Anthropic gives you access to a variety of tools to help you manage your data. You can access these in your Privacy Settings.

5. Data Transfers

Anthropic is a global company, and when you access our Services, your personal data is transferred to our servers in the US, or to other countries outside the European Economic Area (“EEA”) and the UK for the purposes outlined in Section 2 of this Privacy Policy, for example to provide you with the Service, or to train our models, or to conduct research. This may be a direct provision of your personal data to us, or a transfer that we or a third party make. You can find more details about the affiliates and third parties we transfer data to, including their locations, in our Trust Center.

Where Anthropic transfers information outside the EEA or the UK, we ensure it benefits from an adequate level of data protection by relying on:

• Adequacy decisions: These are decisions from the European Commission under Article 45 GDPR (or equivalent decisions under other laws) where they recognize that a country outside of the EEA offers an adequate level of data protection. We transfer your information as described in “Collection of Personal Data” to some countries with adequacy decisions, such as the countries with EU adequacy decisions listed here and countries with UK adequacy decisions listed here; or
• Standard contractual clauses: The European Commission has approved contractual clauses under Article 46 GDPR that allows companies in the EEA to transfer data outside the EEA. These (and their approved equivalent for the UK and Switzerland) are called standard contractual clauses. We rely on standard contractual clauses to transfer information as described in “Collection of Personal Data” to certain affiliates and third parties in countries without an adequacy decision.

In certain situations, we rely on derogations provided for under applicable data protection law to transfer information to a third country. If you have questions about international transfers, or the safeguards we apply, you can contact us.

6. Data Retention, Data Lifecycle, and Security Controls

Anthropic retains your personal data for as long as reasonably necessary for the purposes and criteria outlined in this Privacy Policy and explained further in our privacy center.

When the personal data collected is no longer required by us, we and our service providers will perform the necessary procedures for destroying, deleting, erasing, or converting it into an anonymous form as permitted or required under applicable laws.

Aggregated or De-Identified Information

We apply aggregation and de-identification techniques where appropriate as part of our data minimization practices. For example, we may process personal data in an aggregated or de-identified form to analyze and improve the effectiveness of our Services including to conduct analytics, conduct research, study user behavior, and train our AI models as permitted under applicable laws. For instance:

• When you submit Feedback, we disassociate Inputs and Outputs from your user ID to use them for training and improving our models.
• If our systems flag Inputs or Outputs for harmful content or for potentially violating our policies, we disassociate the content from your user ID to train our trust and safety internal classification and generative models. However, we may re-identify the Inputs or Outputs to enforce our Terms of Service or Usage Policy with the responsible user if necessary.
• To improve user experience, we may analyze and aggregate general user behavior and usage data. This information does not identify individual users.

Where data is de-identified, Anthropic will maintain and use this information in its de-identified form, and will not attempt to re-identify such information, except as permitted by law.

Security Controls Relating to our Processing of Personal Data

We implement appropriate technical and organizational security measures designed to protect personal data from loss, misuse, and unauthorized access, disclosure, alteration, or destruction.

7. Children

Our Services are not directed towards, and we do not knowingly collect, use, disclose, sell, or share any information from children under the age of 18. We have measures in place to detect and remove children from our Services. If you become aware that a child under the age of 18 has provided any personal data to us while using our Services, please email us at privacy@anthropic.com and we will investigate the matter and, if appropriate, delete the personal data.

Supplemental Disclosures for Residents of Brazil

These supplemental disclosures contain additional information relevant to residents of Brazil. This content should be read in conjunction with the rest of our Privacy Policy. In case of conflict between our Privacy Policy and these supplemental disclosures, the supplemental disclosures shall prevail in relation to residents of Brazil.

Legal Bases. Depending on the specific purpose of the processing, we may rely on different grounds than those listed under section 2, where permitted by and in accordance with the Brazilian General Data Protection Law (LGPD). For example, we may rely on the "exercise of legal rights" basis to process personal data associated with customer complaints and to enforce our Terms of Service and similar terms and agreements, including our Usage Policy.

Data Subject's Rights. LGPD grants certain rights regarding your personal data, which differ from the ones listed under section 4. We will respond to your requests to exercise your rights below in accordance with applicable law:

• Confirmation of whether your data is being processed. You have the right to receive a confirmation on whether Anthropic processes your data.
• Access to your data. You have the right to know what personal data Anthropic processes about you.
• Correction of incomplete, inaccurate or outdated data. You have the right to request the correction of your data that is incomplete, inaccurate, or outdated.
• Anonymization, blocking or erasure of data. You have the right to request the anonymization, blocking or erasure of data that is unnecessary, excessive or processed in non-compliance with the provisions of the law.
• Portability of personal data to a third party. You have the right to request portability of your data to a third-party, as long as this does not infringe on our trade secrets.
• Information of public and private entities with which we shared data. You have the right to request information of public and private entities with which we have shared your data.
• Information about the possibility to refuse to provide consent and the respective consequences, when applicable.
• Withdrawal of your consent. You have the right to withdraw your consent. This procedure will be carried out free of charge.
• Request a review of decisions made solely based on automated processing of personal data.

Please keep in mind that these rights are not absolute and may not apply in certain circumstances. For example, in certain cases we may continue to process and retain data regardless of your request for deletion, objection, blocking or anonymisation, in order to comply with legal, contractual and regulatory obligations, safeguard and exercise rights, including in judicial, administrative and arbitration proceedings and in other cases provided for by law.

International Data Transfers. You acknowledge that Anthropic is a company based and headquartered in the United States. Any information we hold about you will be transferred to, used, processed, and stored in the United States and other countries and territories, which may not have data privacy or data protection laws equivalent to those in your country or territory. For the proper operation of the Services, Anthropic needs to carry out international transfers of personal data. In the case of Brazil, we will rely on standard contractual clauses (SCCs) for our data transfers where required and in instances where they are not covered by an adequacy decision. These SCCs have been approved by the Brazilian Data Protection Authority (ANPD), which is the "competent supervisory authority" for these transfers, as governed by Brazilian Data Protection Laws. You can view the SCCs adopted by the ANPD here.
