English

Welcome to Anthropic! Before you access our services, please read these Terms of Service.

These Terms of Service (“Terms”) govern your use of Claude.ai, Claude Pro, and other products and services that we may offer for individuals, along with any associated apps, software, and websites (together, our “Services”). These Terms are a contract between you and Anthropic, PBC ("Anthropic") (and not our Providers), and they include our [Acceptable Use Policy](https://anthropic.com/aup). By accessing our Services, you agree to these Terms.

Please read our [Privacy Policy](https://anthropic.com/privacy), which describes how we collect and use personal information.

Please note: Our [Commercial Terms of Service](https://www.anthropic.com/legal/commercial-terms) govern your use of any Anthropic API key, the [Anthropic Console](https://console.anthropic.com/), or any other Anthropic offerings that reference the Commercial Terms of Service. For clarity, this does not include Claude.ai or Claude Pro use for individuals or entities.

1. Who we are.

Anthropic is an AI safety and research company working to build reliable, interpretable, and steerable AI systems. We conduct frontier research, develop and apply a variety of safety techniques, and deploy the resulting systems via a set of partnerships and products.

2. Account creation and access.

Minimum age. You must be at least 18 years old or the minimum age required to consent to use the Services in your location, whichever is higher.

Your Anthropic Account. To access our Services, we may ask you to create an Account. You agree to provide correct, current, and complete Account information and allow us to use it to communicate with you about our Services. Our communications to you using your Account information will satisfy any requirements for legal notices.

You may not share your Account login information, Anthropic API key, or Account credentials with anyone else. You also may not make your Account available to anyone else. You are responsible for all activity occurring under your Account, and you agree to notify us immediately if you become aware of any unauthorized access to your Account by sending an email to support@anthropic.com.

You may close your Account at any time by contacting us at support@anthropic.com.

Business Domains. If you use an email address owned by your employer or another organization, your Account may be linked to the organization's Anthropic enterprise account, and the organization’s administrator may be able to monitor and control the Account, including having access to Materials (defined below). We will provide notice to you before linking your Account to an organization's enterprise account. However, if the organization is responsible for notifying you or has already informed you that it may monitor and control your Account, we may not provide additional notice.

Evaluation and Additional Services. In some cases, we may permit you to evaluate our Services for a limited time or with limited functionality. Use of our Services for evaluation purposes are for your personal, non-commercial use only.

You may need to accept additional terms to use certain Services. These additional terms will supplement our Terms for those Services and may change your rights or obligations for those Services, including your obligations to pay fees.

3. Use of our Services.

You may access and use our Services only in compliance with our Terms, including our [Acceptable Use Policy](https://anthropic.com/aup), the policy governing [the countries and regions Anthropic currently supports](https://www.anthropic.com/supported-countries) ("Supported Regions Policy"), and any guidelines or supplemental terms we may post on the Services (the “Permitted Use”). You are responsible for all activity under the account through which you access the Services.

You may not access or use, or help another person to access or use, our Services in the following ways:

You also must not abuse, harm, interfere with, or disrupt our Services, including, for example, introducing viruses or malware, spamming or DDoSing Services, or bypassing any of our systems or protective measures.

4. Inputs, Outputs, Actions, and Materials.

Generally. You may be allowed to interact with our Services in a variety of formats (we call these “Inputs”). Our Services may generate responses (we call these “Outputs”), or enable the Services to take actions on your behalf, such as software manipulation, data processing, and system interactions (we call these "Actions"), based on your Inputs. Inputs and Outputs collectively are “Materials.”

Rights and Responsibilities. You are responsible for all Inputs you submit to our Services and all Actions. By submitting Inputs to our Services, you represent and warrant that you have all rights, licenses, and permissions that are necessary for us to process the Inputs under our Terms and to provide the Services to you, including for example, to integrate with third-party services, to share Materials with others at your direction, and to take Actions. You also represent and warrant that your submitting Inputs to us or directing Claude to take Actions will not violate our Terms, our [Acceptable Use Policy](https://anthropic.com/aup), or any laws or regulations applicable to those Inputs or Actions. As between you and Anthropic, and to the extent permitted by applicable law, you retain any right, title, and interest that you have in the Inputs you submit. Subject to your compliance with our Terms, we assign to you all of our right, title, and interest—if any—in Outputs.

Reliance on Outputs and Actions. Artificial intelligence and large language models are frontier technologies that are still improving in accuracy, reliability and safety. When you use our Services, you acknowledge and agree:

Our use of Materials. We may use Materials to provide, maintain, and improve the Services and to develop other products and services, including training our models, unless you opt out of training through your account settings. Even if you opt out, we will use Materials for model training when: (1) you provide Feedback to us regarding any Materials, or (2) your Materials are flagged for safety review to improve our ability to detect harmful content, enforce our policies, or advance our safety research.

5. Feedback

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 related conversation as part of your Feedback. You have no obligation to give us Feedback, but if you do, you agree that we may use the Feedback however we choose without any obligation or other payment to you.

6. Subscriptions, fees and payment.

Fees and billing. You may be required to pay us fees to access or use our Services or certain features of our Services. You are responsible for paying any applicable fees listed for the Services on the [Model Pricing Page](https://www.anthropic.com/pricing) unless otherwise communicated to you by Anthropic in writing.

If you purchase access to our Services or features of our Services, you must provide complete and accurate billing information (“Payment Method”). You agree that we may charge the Payment Method for any applicable fees listed on our Services and any applicable tax. If the fees for these Services or features are specified to be recurring or based on usage, you agree that we may charge these fees and applicable taxes to the Payment Method on a periodic basis.

If you purchase access to our Services through a distributor (e.g. an app store) (“App Distributor”), then you will make payment to the App Distributor, and the App Distributor’s terms in relation to payment methods, billing, and refunds will apply instead of these Terms.

Except as expressly provided in these Terms or where required by law, all payments are non-refundable. Please check your order carefully before confirming it, and see below for additional information about recurring charges for our subscriptions.

Additional fees. We may increase fees for our Services. If we charge additional fees in connection with our Services, we will give you an opportunity to review and accept the additional fees before you are charged. Also, additional fees may apply for additional Services or features of the Services that we may make available. If you do not accept any such additional fees, we may discontinue your access to the Services or features.

You agree that we will not be held liable for any errors caused by third-party payment processors used to process fees paid by you to us.

Subscriptions. To access Claude Pro and other subscription services we may make available to individuals, you must sign up for a subscription with us (a “Subscription”), first by creating an Account, and then following the subscription procedure on our Services. When you sign up for a Subscription, you agree to these Terms.

7. Third-party services and links

Our Services may use or be used in connection with third-party content ("Third-Party Content"), services, or integrations. We do not control or accept responsibility for any loss or damage that may arise from your use of any Third-Party Content, services, and integrations, for which we make no representations or warranties. Your use of any Third-Party Content, services, and integrations is at your own risk and subject to any terms, conditions, or policies (including privacy policies) applicable to such third-party content, services, and integrations.

8. Content Moderation

Third-Party Content is the responsibility of the person or entity that provides it to our Services. Anthropic is under no obligation to host or serve Third-Party Content. Third-Party Content may appear in Inputs or Outputs and become part of Materials. If you see any Third-Party Content you believe does not comply with these Terms, including by violating the Acceptable Use Policy or the law, you can [report](https://docs.google.com/forms/d/e/1FAIpQLSeDGdVzv9XYm0eNaI88Aqm8fXO63UhbvFB9_4t-8CMlfUPewQ/viewform) it to us.

If we become aware that any Third-Party Content (1) infringes another’s copyright or any other intellectual property or related or neighboring right, (2) is in breach of these Terms or our Acceptable Use Policy, or (3) may cause harm to Anthropic, our users, or third parties, we reserve the right to remove or take down some or all of such Third-Party Content using, where appropriate, algorithmic and human review.

You can learn more about our monitoring and enforcement, including how to appeal an account suspension or termination, in our [T&S Support Center](https://support.anthropic.com/en/collections/4078535-trust-safety).

9. Software

We may offer manual or automatic updates to our software including our apps (“Anthropic Software”), without advance notice to you. Anthropic Software may include open source software. In the event of any conflict between these Terms and any other Anthropic or third-party terms applicable to any portion of Anthropic Software, such as open-source license terms, such other terms will control as to that portion of the Anthropic Software and to the extent of the conflict.

10. Ownership of the Services

The Services are owned, operated, and provided by us and our affiliates, licensors, distributors, and service providers (collectively “Providers”). We and our Providers retain all of our respective rights, title, and interest, including intellectual property rights, in and to the Services. Other than the rights of access and use expressly granted in our Terms, our Terms do not grant you any right, title, or interest in or to our Services.

11. Disclaimer of warranties, limitations of liability, and indemnity

Our team works hard to provide great services, and we’re continuously working on improvements. However, there are certain aspects we can’t guarantee. We are using ALL CAPS to explain this, to make sure that you see it.

YOUR USE OF THE SERVICES, MATERIALS, AND ACTIONS IS SOLELY AT YOUR OWN RISK. THE SERVICES, OUTPUTS, AND ACTIONS ARE PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS AND, TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW, ARE PROVIDED WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. WE AND OUR PROVIDERS EXPRESSLY DISCLAIM ANY AND ALL WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE, TITLE, MERCHANTABILITY, ACCURACY, AVAILABILITY, RELIABILITY, SECURITY, PRIVACY, COMPATIBILITY, NON-INFRINGEMENT, AND ANY WARRANTY IMPLIED BY COURSE OF DEALING, COURSE OF PERFORMANCE, OR TRADE USAGE.

TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW, IN NO EVENT WILL WE, OUR PROVIDERS, OR OUR OR THEIR RESPECTIVE AFFILIATES, INVESTORS, DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, SUCCESSORS OR ASSIGNS (COLLECTIVELY, THE “ANTHROPIC PARTIES”), BE LIABLE FOR ANY DIRECT, INDIRECT, PUNITIVE, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR OTHER DAMAGES ARISING OUT OF OR IN ANY WAY RELATED TO THE SERVICES, THE MATERIALS, THE ACTIONS, OR THESE TERMS, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHER THEORY, EVEN IF ANY ANTHROPIC PARTIES HAVE BEEN ADVISED OF THE POSSIBILITY OF DAMAGES, AND EVEN IF THE DAMAGES ARE FORESEEABLE.

TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW, THE ANTHROPIC PARTIES’ TOTAL AGGREGATE LIABILITY TO YOU FOR ALL DAMAGES, LOSSES AND CAUSES OF ACTION ARISING OUT OF OR IN ANY WAY RELATED TO THE SERVICES, THE MATERIALS, THE ACTIONS, OR THESE TERMS, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID TO US FOR ACCESS TO OR USE OF THE SERVICES (IF ANY) IN THE SIX MONTHS PRECEDING THE DATE SUCH DAMAGES, LOSSES, AND CAUSES OF ACTION FIRST AROSE, AND $100. THE FOREGOING LIMITATIONS ARE ESSENTIAL TO THESE TERMS, AND WE WOULD NOT OFFER THE SERVICES TO YOU UNDER THESE TERMS WITHOUT THESE LIMITATIONS.

YOU AGREE TO INDEMNIFY AND HOLD HARMLESS THE ANTHROPIC PARTIES FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, DAMAGES, EXPENSES (INCLUDING REASONABLE ATTORNEYS’ FEES AND COSTS), AND OTHER LOSSES ARISING OUT OF OR RELATED TO YOUR BREACH OR ALLEGED BREACH OF THESE TERMS; YOUR ACCESS TO, USE OF, OR ALLEGED USE OF THE SERVICES, THE MATERIALS, OR THE ACTIONS; YOUR FEEDBACK; ANY PRODUCTS OR SERVICES THAT YOU DEVELOP, OFFER, OR OTHERWISE MAKE AVAILABLE USING OR OTHERWISE IN CONNECTION WITH THE SERVICES; YOUR VIOLATION OF APPLICABLE LAW OR ANY THIRD-PARTY RIGHT; AND ANY ACTUAL OR ALLEGED FRAUD, INTENTIONAL MISCONDUCT, GROSS NEGLIGENCE, OR CRIMINAL ACTS COMMITTED BY YOU OR YOUR EMPLOYEES OR AGENTS. WE RESERVE THE RIGHT TO ENGAGE SEPARATE COUNSEL AND PARTICIPATE IN OR ASSUME THE EXCLUSIVE DEFENSE AND CONTROL OF ANY MATTER OTHERWISE SUBJECT TO INDEMNIFICATION BY YOU HEREUNDER, IN WHICH CASE YOU AGREE TO COOPERATE WITH US AND SUCH SEPARATE COUNSEL AS WE REASONABLY REQUEST.

THE LAWS OF SOME JURISDICTIONS DO NOT ALLOW THE DISCLAIMER OF IMPLIED WARRANTIES OR CERTAIN TYPES OF DAMAGES, SO SOME OR ALL OF THE DISCLAIMERS AND LIMITATIONS OF LIABILITY IN THESE TERMS MAY NOT APPLY TO YOU.

OUR PROVIDERS ARE INTENDED THIRD PARTY BENEFICIARIES OF THE WARRANTY DISCLAIMERS AND LIMITATIONS OF LIABILITY CONTAINED IN THIS SECTION 11.

12. General terms

Changes to the Services. Our Services are novel and will change. We may sometimes add or remove features, increase or decrease capacity limits, offer new Services, or stop offering certain Services.

Unless we specifically agree otherwise in a separate agreement with you, we reserve the right to modify, suspend, or discontinue the Services or your access to the Services, in whole or in part, at any time without notice to you. Although we will strive to provide you with reasonable advance notice if we stop offering a Service, there may be urgent situations—such as preventing abuse, responding to legal requirements, or addressing security and operability issues—where providing advance notice is not feasible. We will not be liable for any change to or any suspension or discontinuation of the Services or your access to them.

Changes to these terms. We may revise and update these Terms at our discretion. Some examples of times, we may update these Terms include (1) to reflect changes in our Services, like when we add or remove features or services, or update our pricing, (2) for security or legal reasons, or (3) to promote safety or prevent abuse. If you continue to access the Services after we post the updated Terms on Anthropic’s website or otherwise give you notice of Terms changes, then you agree to the updated Terms. If you do not accept the updated Terms, you must stop using our Services.

Supplemental terms. We may offer Services or features that we believe require service-specific terms or guidelines. When using our Services, you agree to comply with any applicable guidelines, rules, or supplemental terms that may be posted on the Services from time to time (“Supplemental Terms”). If these Terms conflict with Supplemental Terms, the Supplemental Terms will govern for the applicable Service.

Entire agreement. These Terms and any other terms expressly incorporated by reference form the entire agreement between you and us regarding the subject matter of our Terms.

Termination. You may stop accessing the Services at any time. We may suspend or terminate your access to the Services (including any Subscriptions) at any time without notice to you if we believe that you have breached these Terms, or if we must do so in order to comply with law. If we terminate your access to the Services due to a violation of these Terms and you have a Subscription, you will not be entitled to any refund. In addition, if you have a Subscription, we may terminate the Subscription at any time for any other reason. If we exercise this right and you purchased the subscription via our website, we will refund you, on a pro rata basis, the fees you paid for the remaining portion of your Subscription after termination. Any refunds for Subscriptions purchased via an App Distributor are subject to the App Distributor’s terms and not these terms.

We may also terminate your Account if you have been inactive for over a year and you do not have a paid Account. If we terminate your Account due to inactivity, we will provide you with notice before doing so.

Upon termination of these Terms, a Subscription, or your access to the Services, we may at our option delete any Materials or other data associated with your Account. Sections 6 (with respect to fees outstanding as of such expiration or termination) and 9 – 12 will survive any expiration or termination of our Terms or a Subscription.

Severability. If a particular Term or portion of these Terms is not valid or enforceable, this will have no effect on any other Terms.

No waiver. Any delay or failure on our part to enforce a provision of these Terms is not a waiver of our right to enforce them later.

No assignment. These Terms may not be transferred or assigned by you without our prior written consent, but may be assigned by us without restriction.

Use of our brand. You may not, without our prior written permission, use our name, logos, or other trademarks in connection with products or services other than the Services, or in any other way that implies our affiliation, endorsement, or sponsorship. To seek permission, please email us at marketing@anthropic.com.

Export Controls. You may not export or provide access to the Services into any U.S. embargoed countries or to anyone on (i) the U.S. Treasury Department’s list of Specially Designated Nationals, (ii) any other restricted party lists identified by the Office of Foreign Asset Control, (iii) the U.S. Department of Commerce Denied Persons List or Entity List, or (iv) any other restricted party lists. You represent and warrant that you and anyone accessing or using the Services on your behalf, or using your Account credentials, are not such persons or entities and are not located in any such country.

Legal Compliance. We may comply with governmental, court, and law enforcement requests or requirements relating to provision or use of the Services, or to information provided to or collected under our Terms. We reserve the right, at our sole discretion, to report information from or about you, including but not limited to Inputs, Outputs, or Actions to law enforcement.

U.S. Government Use. The Services were developed solely at private expense and are commercial computer software and commercial computer software documentation within the meaning of the applicable Federal Acquisition Regulations and their agency supplements. Accordingly, U.S. Government users of the Services will have only those rights that are granted to all other end users of the Services pursuant to these Terms.

13. In case of disputes

Equitable relief. You agree that (a) no adequate remedy exists at law if you breach Section 3 (Use of Our Services); (b) it would be difficult to determine the damages resulting from such breach, and any such breach would cause irreparable harm; and (c) a grant of injunctive relief provides the best remedy for any such breach. You waive any opposition to such injunctive relief, as well as any demand that we prove actual damage or post a bond or other security in connection with such injunctive relief.

Governing law and exclusive jurisdiction. Our Terms will be governed by, and construed and interpreted in accordance with, the laws of the State of California without giving effect to conflict of law principles. You and Anthropic agree that any disputes arising out of or relating to these Terms will be resolved exclusively in the state or federal courts located in San Francisco, California, and you and Anthropic submit to the personal and exclusive jurisdiction of those courts. By accessing our Services, you waive any claims that may arise under the laws of other jurisdictions.
