// FAQ

Frequently asked

• I forgot my password. Can I recover my vault? +

  No — by design. Argon2id key derivation means your password is never stored or transmitted, only a verifier. If you've lost it and have no recovery key set, the vault content is unrecoverable. This is the trade-off for 'no cloud, no backdoor.'

• Where is my data stored? +

  On your devices. Cypherrum does not have a server that holds your vaults. Sharing between your own devices and trusted contacts goes peer-to-peer over the mesh; a TURN relay is used only as a fallback when P2P can't connect through a hostile NAT.

• Does Cypherrum send telemetry? +

  No. The app does not phone home with usage data. The only network calls it makes by default are update checks against our signed release manifest and (when you enable sharing) peer connections over the mesh.

• Can I use Cypherrum offline? +

  Yes. Local vault use needs no network. Sharing and mesh features need a network. Update checks are best-effort; the app works without them.

• Is the source code public? +

  The cypherrum-relay (the TURN/STUN fallback) is open source under GPL-3.0. The desktop app is closed source — license holders receive signed binaries, not source code. We do not claim to be 'open source' for the desktop app. The on-disk vault format is documented publicly so anyone can write a compatible reader without our source.

• How do I report a bug? +

  Open an issue at github.com/logiqum/cypherrum-releases/issues — pick the 'Bug report' template and fill in version, OS, repro steps, expected vs actual. For 'how do I' questions, use Discussions instead so others can find the answer.

• How do I report a security vulnerability? +

  Email security@cypherrum.com — do not file a public issue. We aim to acknowledge within 72 hours. Coordinated disclosure window is 90 days; we'll work with you on credit in the release notes.

• Is Cypherrum free? +

  The Free tier covers the core encrypted vault, local use, and LAN / direct-WAN sharing — no account, no email, no telemetry. Premium and Team tiers add unlimited vaults, biometric and FIDO2 unlock, relay-backed sharing, and (Team) audit log + master-key escrow. See the pricing page for the full feature matrix.

• Where are the mobile apps? +

  iOS and Android are on the v1.0 roadmap — not shipped yet. Desktop (Windows / macOS / Linux) is fully supported today.

• How do I migrate an existing Cryptomator vault? +

  The app has a Cryptomator vault importer — open Cypherrum, choose 'Import vault,' and point it at the Cryptomator vault directory. See the user guide for the exact flow.
