Zero-knowledge and fully offline. No servers, no accounts — the app doesn't even request the INTERNET permission. Your secrets physically cannot leave the device.
Android · fully offline · AES-256-GCM · Argon2id
Pick a track and tap through the screens that matter to you — real screens from the app, no mock-ups.
Trust isn't asked for — it's verified. Hypervault's cryptographic core is published as a standalone module with its whitepaper and test vectors.
Standard, audited primitives only — Argon2id, HKDF-SHA-256 and AES-256-GCM, with all randomness from a CSPRNG.
Pure Kotlin, one dependency, no Android code — easy to read and audit end to end.
Your entire vault is one portable file. Back it up anywhere — without your device and master password it is just noise.
Entry names, URLs and structure all live inside the encrypted body. The header holds only crypto parameters.
Flip a single byte and authentication fails. The body is cryptographically bound to its header.
A stolen file is undecryptable even with a weak password — the 128-bit Secret Key is the second component.
From a shipped 1.0 to a network of devices across Android, iOS and macOS — every release stays fully offline and holds the same security standard.
The full offline vault: passwords, air-gapped wallet, 2FA, encrypted files, duress-PIN and dead-man switch — shipped and stable.
ShippedExtending fully offline QR signing to Bitcoin (PSBT) and Solana — sign on the air-gapped phone, broadcast from a watch-only wallet.
In progressMove big encrypted files between devices — chunked AEAD transport over any channel, ciphertext only, no size ceiling.
PlannedLink X devices into one network — your phone becomes the key to a corporate environment with flexible permissions, still with no internet and the same security standard. Ships alongside the native iOS release.
Vision · 2026The full vault, wallet and HVN on the desktop — a native macOS app closing the loop across phone, tablet and Mac, on the same encrypted HV1 core.
Vision · 2026Same app, same encryption. Choose how much you want the app to be able to reach the outside world.
The right pick for almost everyone. A fully secure vault that also sends anonymous crash reports (Firebase Crashlytics) so we can fix issues fast — your vault contents are never part of it.
Download Secret Download SHA-256Fully offline — the app can't reach the network at all. Pick this only if you want zero connectivity and don't mind losing crash diagnostics.
Download Blackout Download SHA-256Both builds are downloaded over HTTPS and signed. Before installing, you can verify the published SHA-256 checksum and the app's signing certificate — or grab it from Google Play / RuStore, which verify the signature for you.
Hypervault has no ads, no subscriptions, no telemetry — and no revenue. If it protects something you care about, a donation keeps the audits coming.
