Privacy Policy

Effective: 2025-08-22

What we are

GreenCoast is a zero-trust, end-to-end encrypted (E2EE) social platform. By default, we do not collect analytics, do not store personal data, and do not maintain server logs that identify users.

Data we process

• Public posts: Stored as plaintext objects keyed by content hash. No account profile is required.
• Private posts: Encrypted client-side with a passphrase only you know. The server sees ciphertext only.
• Authorization: Device-key and/or third-party SSO (if you choose) issue a short-lived bearer. We do not persist profile data.

Third-party SSO

If you use Discord/Google/etc., those providers may process your data under their own terms. We cannot vouch for their security.

Cookies & local storage

We use browser storage on your device to keep connection settings and, if you choose, session tokens. You can wipe them with “Panic wipe”.

Security

E2EE for private content, proof-of-possession on mutations, rate-limits, CSP/COOP/COEP, and optional hardware keys via WebAuthn (if enabled on your shard).

Your rights

Because we do not maintain user identities or server-side profiles, requests to access/correct/erase personal data typically do not apply. For encrypted content, we cannot decrypt it for you.
