Vaultaire is iPhone-only. Dead Safe Vault is being built for Android, with the same kind of features and one big difference: it has no internet access at all.
Vaultaire is a well-made app, and its security documentation is unusually honest about its own limits, which is why this comparison can be precise. Where it's ahead, we say so.
| Checked 2026-11-05 | Vaultaire | Dead Safe Vault (in development) |
|---|---|---|
| Runs on | iPhone and iPad (iOS 17 or later) | Android |
| Account or email needed | No | No |
| Can connect to the internet | Yes (analytics and iCloud backup are on by default; sharing and sync use iCloud) | No (no internet permission, so Android blocks every connection; anyone can check this in the app file) |
| Usage and crash data | Sent to PostHog by default; can be turned off | None: the app has no way to send it |
| Encryption | AES-256-GCM | XChaCha20-Poly1305 (both are modern authenticated encryption) |
| How your pattern becomes a key | PBKDF2-HMAC-SHA512, 600,000 rounds, with a salt kept in the iOS Keychain | Argon2id (designed to make guessing slow and memory-hungry), then combined with a key inside the phone's security chip that can't be copied out |
| Can a copy of the vault be guessed at on another computer? | Yes (Vaultaire's own documentation says a guess can be checked offline against the encrypted data) | No (each guess needs this phone's security chip; the app tells you if a phone has none) |
| Pattern grid | 5 × 5, at least 6 dots | 6 × 6, at least 8 dots, or a passphrase |
| Duress pattern (opens one vault, removes the others) | Yes (the other vaults' files are deleted without overwriting; the duress setting can be seen by someone with access to the Keychain) | Yes (each other vault's key is destroyed in the security chip, so even copies taken earlier can't be opened; the duress mark is hidden inside the encrypted vault) |
| Disguise | Icons only (utility icons such as Calculator; the name under the icon stays Vaultaire and it opens the pattern screen) | Yes (shows as "Calculator", name included, and opens a working calculator; your code then shows the lock screen) |
| Backups | Encrypted iCloud backup, on by default | Encrypted backup to a place you choose (Google Drive, a USB stick, an SD card...), locked with 12 recovery words, with a padded size |
| Sharing | Through iCloud; one-time phrase; read-only; can be revoked | An encrypted file, no server; needs both the recipient's phone and a one-time phrase; read-only; receipt when opened; can't be revoked once sent |
| Sync between your own devices | Yes (through iCloud) | No (not yet) |
| Videos | Yes | Yes (played from memory, never saved decrypted to a file) |
| Spyware check | Not described | Yes (known stalkerware, apps that can read the screen, overlays; see its limits below) |
| Open source | Not stated | Planned before launch |
| Independent security audit | Not stated | No (planned before 1.0) |
| Released | Yes (App Store) | No (in development) |
Vaultaire sends anonymous usage and crash data to an analytics service by default (you can switch it off), and backs up to iCloud by default. Dead Safe Vault's app file declares no internet permission, so Android refuses every connection it tries to make. It can't send anything to us or anyone else, and you don't have to take our word for it: the permission list is in the app file for anyone to read.
A pattern is short, so the question is where an attacker can try guesses. Vaultaire's documentation says that someone who copies the encrypted files can test guesses offline, slowed down by 600,000 rounds of PBKDF2. Dead Safe Vault mixes your pattern with a key held in the phone's security chip, which can't be copied out, so a copy of the vault on someone's computer gets them nowhere.
Both apps let a forced unlock open one harmless vault and remove the others. Vaultaire deletes the other vaults' files without overwriting them. Dead Safe Vault gives every vault its own key in the security chip and destroys those keys, so the other vaults can never be opened again, even from a copy of the phone's storage taken earlier.
On an iPhone: Vaultaire is a sound choice, and its documentation tells you exactly what it protects against. Consider switching its analytics off in Settings.
On Android: Vaultaire isn't available. Dead Safe Vault is built for Android, for people who want a vault that can't connect to the internet.
No. Vaultaire is made for iPhone and iPad (iOS 17 or later). Dead Safe Vault is being built for Android with the same kind of features: no account, a pattern lock, several vaults, a duress pattern, a disguise and encrypted backups.
Vaultaire uses the internet for analytics (on by default), iCloud backup and sharing. Dead Safe Vault has no internet permission at all, ties every guess at your pattern to the phone's security chip, and backs up to a place you choose. Vaultaire is released and syncs between devices; Dead Safe Vault is still in development and hasn't had an independent audit yet.
