Built on trust

Your money is private. We mean it.

A side-by-side rundown of every layer of defence between attackers and your data.

End-to-end encryption

TLS 1.2+ in transit and AES-256 at rest. Your ledger never leaves the wire unencrypted.

PIN + biometric lock

Optional 4–6 digit PIN with fingerprint/face unlock. Auto re-locks on background.

Per-user Firestore rules

Server-side rules guarantee only the signed-in owner can read or write their own document tree.

Firebase infrastructure

Google Cloud hosts our auth, database, storage, and push messaging — SOC 2, ISO 27001 certified.

Granular file access

Volt documents live in your private Storage folder with 15 MB / image+PDF whitelist enforced at the rule layer.

Zero tracking, zero ads

No third-party analytics inside the app. No advertising SDKs. Only anonymised crash reports.

Responsible disclosure
