Data Collection Methods

We support multiple account creation methods including email/password, OAuth (Google Sign-in), and other authentication methods. Some data collection is required for core functionality, while other data is optional.

Password Vault (End-to-End Encrypted)

Public provides an optional in-app Password Vault that lets you save website credentials (site name, URL, email or username, password, and notes) and sync them across your devices. The vault is designed as a zero-knowledge system: your credentials are encrypted on your device before they ever reach our servers, and we cannot decrypt them under any circumstances.

How your passwords are protected

  • β€’ You choose a master password known only to you. It is never sent to our servers and is never persisted on your device.
  • β€’ Your master password is run through Argon2id, a memory-hard key-derivation function, to derive a 256-bit key.
  • β€’ That key is used only to unwrap a randomly generated vault key, which in turn encrypts every saved credential with AES-256-GCM on your device.
  • β€’ Only the resulting opaque ciphertext, the random nonce, and the public KDF parameters are transmitted (over HTTPS) and stored on our servers.

What we store on our servers

  • β€’Encrypted blob: the AES-GCM ciphertext for each saved entry
  • β€’Random nonce: a 12-byte initialisation value per entry
  • β€’KDF parameters: salt, memory cost, time cost, and parallelism
  • β€’Wrapped vault key: your random vault key encrypted by your master-password-derived key
  • β€’Verifier blob: a tiny known constant encrypted with the same key, used by your device to detect a wrong master password

What we cannot see

  • β€’The plaintext of any saved password
  • β€’The websites, apps, emails, or usernames inside your vault
  • β€’Your master password β€” at any point, on any device
  • β€’Any data that would let us or a third party recover your vault without the master password

Master password is unrecoverable

Because zero-knowledge encryption means we never hold your key, we cannot reset or recover your master password. If you forget it, the encrypted data on our servers becomes permanently unreadable and we will not be able to restore your saved credentials. You can change your master password from within the app while your vault is unlocked; this re-wraps the same vault key without re-encrypting individual entries.

Additional safeguards on your device

  • β€’ Vault screens use Android's FLAG_SECURE to block screenshots and hide content from the app switcher.
  • β€’ Your unlocked vault key is held only in memory and is automatically wiped after a short period of inactivity.
  • β€’ When you copy a password to your clipboard, it is marked as sensitive on Android 13+ and automatically cleared after 30 seconds.
  • β€’ You can delete individual entries or your entire account at any time from within the app.

The Password Vault is an opt-in feature. If you never create a vault, no credential data of this type is collected. The vault is independent of the password you use to sign in to your Public account β€” the two are stored and protected separately.
