Privacy & Cookie Policy

Last Updated: January 2026

"Your privacy is not just a policy, it's our architecture. Kairos Vault is designed to know as little as possible about you."

Data We Collect

We only collect your email address for authentication and notification purposes. We do not track your IP address or perform browser fingerprinting.

Cookies

We use essential technical cookies solely for authentication (Supabase Auth). No third-party tracking, analytics, or advertising cookies are used.

Files & Encryption

Before the release date, your files are stored heavily encrypted and fragmented across our decentralized P2P network. After the release date, reconstructed files are temporarily stored on secure cloud storage to facilitate download, based on your plan's retention policy. You can manually delete them at any time.

Third-Party Processors

To provide our service, we rely on trusted infrastructure partners who act as Data Processors: Supabase (Authentication & Database), DigitalOcean Spaces (File Storage post-release), and Brevo (Transactional Emails).

Your Rights & Zero-Knowledge Limitations

Under the GDPR, you have the right to access, rectify, delete, and port your data. However, due to our Zero-Knowledge and Time-Lock architecture, we cannot recover forgotten passphrases, nor can we bypass the time-lock to retrieve files for you or law enforcement.
