What Sessyn stores on its coordinator
- Your account email (from Google OAuth) and a stable user ID.
- The set of machines you've registered, with display names you chose.
- Workspace generation metadata: timestamps, file paths, file hashes, sizes — not file contents.
- Encrypted file blobs only while they are in flight between your machines. Blobs are deleted after every paired machine has acknowledged delivery, or after a hard TTL — whichever comes first.
- Standard server logs (IP, request path, status code, timestamp), retained for 30 days, used only for abuse and reliability.
What Sessyn does not store, ever
- Plaintext file contents. Files are encrypted client-side with AES-256-GCM before upload.
- Decryption keys. Per-pair keys live only on your trusted machines.
- Any analytics, advertising IDs, behavioural tracking, or third-party telemetry.
