Privacy Policy

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 and other places where Anthropic acts as a data controller—for example, when you interact with Claude.ai or other products as a consumer for personal use ("Services") or when Anthropic operates and provides our commercial customers and their end users with access to our commercial products, such as the Claude Team plan (“Commercial Services”).

This Privacy Policy does not apply where Anthropic acts as a data processor and processes personal data on behalf of commercial customers using Anthropic’s Commercial Services – for example, your employer has provisioned you a Claude for Work account, or you're using an app that is powered on the back-end with Claude. In those cases, the commercial customer is the controller, and you can review their policies for more information about how they handle your personal data.

For information about how we collect and use personal data to develop our language models that power our Services, and your choices with respect to that information, please see our Notice on Model Training.

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, please read section 11 of the Privacy Policy which applies to you.

If you are located in Brazil, please read section 12 of the Privacy Policy which applies to you.

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 products and services.
• Inputs and Outputs: Our AI services allow you to interact with the Services in a variety of formats (“Prompts” or "Inputs"), which generate responses (“Outputs”) based on your Inputs. If you include personal data in your Inputs, we will collect that information and this information may be reproduced in your Outputs.
• 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 will store the entire related conversation as part of your Feedback. You can learn more about how we use Feedback here.
• 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.

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:

• 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

We use your personal data for the following purposes:

• With an individual's consent. Anthropic will otherwise disclose personal data when an individual gives us permission or directs us to disclose this information.

You can find information on our Subprocessor List about the third parties Anthropic engages to help us process personal data provided to us where Anthropic acts as a data processor, such as with respect to personal data we receive, process, store, or host when you use Anthropic's commercial services.

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 process 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 emailing us at privacy@anthropic.com. After we receive your request, we may verify it by requesting information sufficient to confirm your identity. 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.

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. 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.

5. Data Transfers

When you access our website or Services, your personal data may be transferred to our servers in the US, or to other countries outside the European Economic Area (“EEA”) and the UK. This may be a direct provision of your personal data to us, or a transfer that we or a third party make.

Where information is transferred 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 recognise 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 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.

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 may process personal data in an aggregated or de-identified form to analyze the effectiveness of our Services, 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 potentially violating our Usage Policy, 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 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.

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 about, children under the age of 18.

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.
