AlterVault: Hidden Photo Vault

AlterVault is a hidden photo vault that keeps your private photos, videos and documents encrypted on your phone. No account to make, nothing uploaded, nothing to sign in to. ENCRYPTED BEFORE IT TOUCHES THE DISK
Every file is sealed with XChaCha20-Poly1305: your photos, your videos, your documents, and the thumbnails and filenames too. Your PIN unwraps the key through Argon2id and is never stored anywhere, so nobody can open your vault without it.

TWO GALLERIES, ONE SHAKE
Your vault can hold more than one gallery. A second one comes ready to use, and shaking the phone switches to it. Shake again, enter your PIN, and you are back in the main one. Setup walks you through the gesture once, and its sensitivity is yours to tune in Settings.

NO CLOUD, NO ACCOUNT
Your photos, videos, documents and their filenames never leave the phone. Only three things do: anonymous usage events and crash reports, what a purchase needs, and feedback you choose to send. None of it is tied to your name. The privacy policy lists all of it.

IN THE APP
• Add photos and videos from your gallery, or any file from your phone: PDFs, documents, audio
• Albums, and a filter for media or files
• Full-screen viewer with video playback, decrypted in memory only
• Screenshots and screen recording blocked while an item is open
• Blank in the recent apps screen; auto-lock immediately, after 1 minute or after 5
• Save anything back to your Gallery or Downloads at original quality, or share it. No lock-in
• An encrypted backup file you can keep anywhere and restore on a new phone
• A twelve-word recovery phrase, in case you forget your PIN
• 13 languages, dark and light

FREE AND PRO
Free shows 10 items, and the second gallery and the shake are included. Pro removes the limit and adds more private spaces, each with its own PIN, plus custom app icons. Pay once for life, or monthly. The monthly plan renews until you cancel it in Google Play.

BEFORE YOU START
Your files are encrypted with a key only your PIN can unwrap. Nobody can reset it for you, not us and not Google. Write your recovery phrase down, and keep a backup file somewhere safe.

AlterVault is a private gallery, a secret photo album, a photo locker and a file safe in one app: hide photos, hide videos, lock pictures and documents behind a PIN, and keep your private photos safe and out of the cloud.
