Terms of Service

Last updated: January 29th, 2026.

These Terms of Service (“Terms”) govern access to and use of the services, software, APIs, and websites (collectively, the “Services”) provided by Better Auth, Inc. (“Company,” “we,” “us,” or “our”). These Terms apply to customers that create an account or otherwise use the Services (“Customer,” “you,” or “your”). If you are using the Services on behalf of an organization, you represent and warrant that you have authority to bind that organization.

By accessing or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

1. Description of the Services

The Services provide authentication and related functionality, including APIs, SDKs, dashboards, and developer tools, that enable Customers to authenticate and manage their end users (“End Users”).

We may modify, update, or discontinue portions of the Services from time to time. We will use commercially reasonable efforts to notify you of material changes that adversely affect the Services.

2. Account Registration and Administration

2.1 Account Creation

You must create an account to use the Services. You agree to provide accurate, current, and complete information and to keep your account information up to date.

2.2 Account Security

You are responsible for maintaining the confidentiality of your credentials and for all activities that occur under your account. You must promptly notify us of any unauthorized access or security incident related to your account.

2.3 Administrators

You may designate administrators who can manage your account, configuration, integrations, and End User access. You are responsible for the actions of your administrators.

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable right to access and use the Services for your internal business purposes and to authenticate your End Users.

  • Reverse engineer, decompile, or disassemble the Services;
  • Circumvent usage limits, security features, or access controls;
  • Use the Services to violate applicable laws or regulations;

You are responsible for your End Users’ compliance with these Terms and for obtaining all necessary consents, notices, and permissions required to authenticate and process End User data.

4. Customer Data and Privacy

4.1 Customer Data

“Customer Data” means data, content, and information submitted to the Services by you or your End Users, including identifiers, authentication credentials, metadata, and logs.

You retain all rights to Customer Data. We process Customer Data solely to provide and improve the Services, in accordance with these Terms and our Privacy Policy.

4.2 Data Protection

We will implement reasonable administrative, technical, and physical safeguards designed to protect Customer Data. Details regarding our data practices are described in our Privacy Policy.

4.3 Data Processing Addendum

If required by applicable law (including GDPR), the parties will enter into a Data Processing Addendum (“DPA”), which will govern the processing of personal data.

5. Security and Compliance

We maintain an information security program designed to protect the confidentiality, integrity, and availability of the Services and Customer Data. This may include industry-standard controls such as encryption, access controls, and monitoring.

You acknowledge that no system is completely secure and that we do not guarantee absolute security.

6. Service Levels and Support

Any service level commitments or support obligations will be set forth in a separate Service Level Agreement (“SLA”) or order form, if applicable. Absent an SLA, the Services are provided on a commercially reasonable efforts basis.

7. Fees and Payment

7.1 Fees

You agree to pay all fees specified in an applicable order form or pricing page. Fees are non-refundable except as expressly stated.

7.2 Usage-Based Fees

If fees are based on usage (e.g., security events, authentication events), you are responsible for monitoring usage and associated costs.

7.3 Taxes

Fees are exclusive of taxes. You are responsible for all applicable taxes, except for taxes based on our net income.

8. Intellectual Property

8.1 Company IP

We retain all right, title, and interest in and to the Services, including all intellectual property rights. No rights are granted except as expressly stated.

8.2 Feedback

You may provide feedback or suggestions regarding the Services. We may use such feedback without restriction or obligation to you.

9. Confidentiality

Each party may receive confidential information of the other. Confidential information must be protected using reasonable care and used only to fulfill obligations under these Terms.

Confidential information does not include information that is publicly available, independently developed, or rightfully obtained without breach of confidentiality.

10. Third-Party Services

The Services may integrate with third-party products or services. We are not responsible for third-party services and disclaim all liability related to them. Your use of third-party services is governed by their terms.

11. Suspension and Termination

11.1 Suspension

We may suspend access to the Services if you violate these Terms, pose a security risk, or fail to pay applicable fees.

Either party may terminate these Terms upon written notice if the other party materially breaches and fails to cure within 30 days.

Upon termination, your right to use the Services ceases. Upon request, we will make Customer Data available for export for a limited period, subject to applicable law.

Except as expressly provided, the Services are provided “as is” and “as available.” We disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

13. Limitation of Liability

To the maximum extent permitted by law, in no event will our total liability arising out of or related to the Services exceed the amounts paid by you to us in the 12 months preceding the event giving rise to the claim.

In no event will we be liable for indirect, incidental, consequential, special, or punitive damages.

14. Indemnification

You agree to indemnify and hold harmless the Company from claims arising out of your use of the Services, your Customer Data, or your violation of applicable law.

These Terms are governed by the laws of the State of California, excluding conflict of law principles. Any disputes will be resolved in the state or federal courts located in San Francisco County, California, and the parties consent to personal jurisdiction.

16. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated through the Services or by other reasonable means. Continued use of the Services constitutes acceptance of the updated Terms.

17. General

These Terms constitute the entire agreement between the parties regarding the Services and supersede all prior agreements. If any provision is held unenforceable, the remaining provisions will remain in effect.

You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
