OffVault

Your private photos deserve a vault that physically cannot leak. OffVault locks your photos, videos, documents and passwords behind military-grade encryption — and it works 100% offline. No internet. No cloud. No accounts. Everything stays on your phone, encrypted, and under your control alone.

🔒 SERIOUS ENCRYPTION, IN PLAIN WORDS
✦ Every file is sealed with AES-256-GCM — the same encryption standard banks and governments rely on
✦ Each file gets its own unique key, so one file can never expose another
✦ Your PIN is hardened with Argon2id, a modern algorithm built to defeat brute-force and password-cracking rigs
✦ The app's database is fully encrypted with SQLCipher
✦ Tamper detection: if anyone modifies an encrypted file, OffVault knows

📵 100% OFFLINE — BY DESIGN, NOT BY PROMISE
OffVault does not even request internet permission from Android. That means your files physically cannot be uploaded, synced or sent anywhere — the operating system itself blocks it.
✦ No sign-up, no account, no email required
✦ No analytics, no ads, no trackers, no crash reporting
✦ Nothing ever leaves your device. Delete the app, and the data is gone with it

🖼️ WHAT YOU CAN LOCK
✦ Photos & videos — imported into a beautiful encrypted gallery with folders, favorites, image zoom and smooth video playback
✦ Documents and any file type — PDFs, backups, anything private
✦ Encrypted notes — for thoughts that are nobody's business
✦ Password manager — store logins securely, with a strong password generator and strength meter
✦ Export or share a decrypted copy anytime — you stay in charge

🎭 DECOY VAULT
Forced to open your vault? Enter your fake PIN instead. It opens a separate, innocent-looking vault with its own encryption keys — your real vault stays invisible.

⚡ SMART PROTECTION
✦ PIN lock + fingerprint/face unlock
✦ Auto-lock the moment you switch apps (instant, 15s, 30s, 1m or 5m)
✦ Shake-to-lock panic gesture — one shake and the vault slams shut
✦ Screenshot and screen-recording blocking inside the app
✦ Intruder log — see every failed unlock attempt
✦ Live security score and a full security event timeline

⚠️ AN HONEST WARNING
If you forget your PIN, there is no recovery. No reset email, no backdoor, no way in — not even for us. That is not a flaw; that is real security. Choose a PIN you will remember.

OffVault is built for everyone who believes private should mean private — no servers, no strangers, no fine print.
