Privacy Policy

Effective April 29, 2026 · Last updated April 29, 2026

This Privacy Policy explains how Human Frontier Labs Inc.(“Sontara,” “we,” or “us”) handles personal information when you use sontara.ai, our mobile applications, and related services (the “Service”). We’ve tried to write this in plain English. If anything is unclear, email privacy@sontara.ai.

1. The short version

2. Information we collect

2.1 Information you give us

2.2 Information generated by your use of the Service

2.3 Mobile-app specifics

3. How we use information

We use the information described above to:

We do not use your conversations, files, or agent memory to train AI models, profile you for advertising, or share with data brokers.

4. Service providers

We engage third parties to help operate the Service. Their roles fall into a small number of categories:

We bind each provider by contract to confidentiality and appropriate security. A current list of subprocessors with specifics is available to enterprise customers, regulators, and auditors on request via privacy@sontara.ai.

5. International data transfers

Sontara is operated from the United States. If you access the Service from outside the U.S., your information will be transferred to and processed in the U.S. and other jurisdictions where our service providers operate. By using the Service, you consent to this transfer.

6. Data retention

We retain personal information for as long as your account is active or as needed to provide the Service. After you delete your account, we delete or anonymize your information within a reasonable period, except where we are required to retain it for legal, tax, accounting, or fraud-prevention purposes (for example, payment records may be retained by our payment processor for several years to satisfy tax and PCI compliance obligations).

7. Your rights

Regardless of where you live, you can:

European Economic Area, United Kingdom, and Swiss residents have additional rights under the GDPR (and UK equivalent), including the right to lodge a complaint with your data-protection authority. California residents have rights under the CCPA / CPRA, including the right to know, the right to delete, the right to correct, and the right to opt out of the “sale” or “sharing” of personal information — we do neither.

To exercise any right, email privacy@sontara.ai. We may ask you to verify your identity before fulfilling certain requests.

8. Children

Sontara is not directed to children under 13, and we do not knowingly collect personal information from anyone under 13. If you believe a child has provided us with personal information, contact privacy@sontara.ai and we will delete it.

9. Security

We use industry-standard practices to protect your information, including encryption in transit and at rest, isolation of your agent’s runtime from other customers’, access controls on internal systems, and the principle of least privilege for engineering access. No system is perfectly secure; if you become aware of a vulnerability, please report it to privacy@sontara.ai.

10. Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes we will notify you by email or in-app notice and update the “Last updated” date above. Continued use of the Service after a change indicates your acceptance.

11. Contact

Questions, concerns, or requests under this policy should go to privacy@sontara.ai.
