Privacy Policy.

Who we are

Sovereign Sign Protocol ("SSP") is the data controller for personal data processed in the application. Contact: privacy@ssp.invalid. EU representative: rep@ssp.invalid.

Data we process

  • Account: email, display name, hashed password (managed by our auth provider).
  • Masters: audio files you upload to a private bucket, plus SHA-256 hash, ISRC, ISWC, title, artist, duration.
  • Splits: contributor names, roles, Polygon wallet addresses, basis-point shares.
  • Wallet attestations: the signed EIP-191 message and signature proving you control a wallet.
  • Sanctions screening: cached boolean result from the Chainalysis OFAC oracle for each wallet you use.
  • Consent ledger: which cookie / policy versions you accepted, when, with a salted-hash of your IP and your user agent.
