Terms of Service

Last updated: March 21, 2026 · Patent Pending — EP26025007.1

1. Introduction

These Terms of Service (“Terms”) govern your access to and use of the TreeChain encrypted data infrastructure platform, including all APIs, SDKs, documentation, and related services (collectively, the “Service”). By accessing or using the Service you agree to be bound by these Terms.

TreeChain is operated under patent application EP26025007.1 and is subject to the jurisdiction of the Republic of Poland and applicable European Union law.

2. Acceptable Use

Prohibited content and activities. You may NOT use the Service to encrypt, store, transmit, or otherwise process any of the following:

For the complete prohibited-use list and enforcement procedures, see our Acceptable Use Policy.

3. Zero-Knowledge Architecture

TreeChain architecturally cannot access customer data. The Service is designed so that all customer content is encrypted client-side before it reaches TreeChain infrastructure. TreeChain does not hold decryption keys and cannot decrypt, read, inspect, or produce customer data in response to any legal request, subpoena, or court order. This is a mathematical property of the system, not a policy choice.

Because of this architecture, TreeChain’s ability to moderate content is limited to metadata-level signals (API usage patterns, abuse reports, etc.). Users bear full responsibility for the legality of the content they encrypt.

4. Liability Limitation

To the maximum extent permitted by applicable law, TreeChain’s total aggregate liability arising out of or relating to the Service shall not exceed the fees actually paid by you to TreeChain during the three (3) months immediately preceding the event giving rise to the claim.

In no event shall TreeChain be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, profits, or business opportunities, regardless of the theory of liability.

5. Service Availability

TreeChain provides the Service on a best-efforts uptime basis. No specific service-level agreement (SLA) is provided unless you are subscribed to an Enterprise plan with a separately executed SLA addendum.

TreeChain may perform scheduled maintenance with reasonable advance notice and reserves the right to modify or discontinue features with thirty (30) days’ notice.

6. API Usage Limits

API rate limits and quotas are determined by your subscription tier:

Exceeding your tier’s limits may result in throttling or temporary suspension of API access. Sustained overuse without upgrading may be treated as a Terms violation.

7. Account Termination

TreeChain reserves the right to suspend or terminate your account and API keys at any time if:

You may terminate your account at any time through the dashboard. Upon termination, your encrypted data will be purged within thirty (30) days in accordance with our data retention policy.

8. GDPR Compliance

TreeChain is committed to full compliance with the General Data Protection Regulation (EU) 2016/679 (“GDPR”). For details on data collection, processing, retention, and your rights as a data subject, see our Privacy Policy.

9. Governing Law & Jurisdiction

These Terms are governed by and construed in accordance with the laws of the Republic of Poland and applicable European Union regulations. Any disputes shall be submitted to the exclusive jurisdiction of the courts of Warsaw, Poland.

10. Changes to These Terms

TreeChain may update these Terms from time to time. Material changes will be communicated via email or a prominent notice within the Service at least thirty (30) days before they take effect. Continued use after changes constitutes acceptance.
