Weave Vault on Android

Weave Vault is a single product built twice, not an iPhone app with a port bolted on. The encryption is identical on both: the same AES-256-GCM sealing, the same Argon2id parameters, the same BIP-39 recovery phrases. A vault created on one behaves the same way on the other.

What Android has today

• Pattern unlock on the same 5×5 grid, with the pattern never written to disk.
• Multiple vaults — every pattern opens its own, with no list and no count.
• AES-256-GCM on files, thumbnails, filenames and metadata.
• Encrypted backup to the hidden application folder of your own Google Drive.
• The in-app camera, capturing straight into the vault rather than the gallery.
• Large files, streamed and sealed in 4 MB chunks.
• Folders — organise inside a vault, with the folder names sealed like everything else.
• Secure sharing — send a point-in-time copy of a vault, openable with a one-time phrase.
• Duress mode — a second pattern that makes the device forget its keys to the others.

The same product, built twice

Every feature on this site is available on both platforms. Some arrived on iPhone first and Android second, but the encryption, the vault model and the recovery phrases are identical — a vault created on one behaves the same way on the other.

Platform differences worth knowing

On Android, release builds mark the vault window as secure, so the system declines to screenshot or record it at all. On iOS the app instead detects the capture and locks. Different mechanisms, same intent — and on neither platform would we describe it as making screenshots impossible.

Vault storage is also excluded from Android's cloud backup and device-transfer paths, so a routine phone backup does not carry it.

Available on Android 8.0 and later, via Google Play.
