About this app

Guardian keeps your most private things in one encrypted place on your phone.

WHAT YOU CAN STORE
• Passwords, with a generator, strength meter and automatic clipboard clearing
• Photos and videos, with an in-app viewer and player
• Notes, credit cards, contacts, websites and any file

BUILT FOR PRIVACY
• Works offline: no account, no servers of ours, no analytics
• Strong encryption (AES-256, Argon2id, SQLCipher) for the database and every file
• Unlock with a master password or PIN, plus fingerprint or face unlock
• Screenshots and recent apps never show your content
• Auto-lock when you leave the app

BACKUP YOUR WAY
• One encrypted backup file you can save anywhere
• Optional upload to your own Google Drive (the app can only see files it created)
• Restore on a new device with your master password

MORE
• Private browser: browse with no history or cookies saved, and send downloads straight into your encrypted vault
• Intrusion alert (optional): if someone enters a wrong password, the app can photograph them and note where it happened. Everything stays encrypted on your device
• Private apps: shortcuts to open other apps from your vault, plus a guide to hide apps with Android's Private Space (Guardian does not hide apps itself)
• Light, dark and automatic themes; English, Portuguese, Spanish, Italian, French and German

FREE AND PRO
Try it free with generous limits. Unlock Pro once for unlimited storage and extra features. One payment, no subscription.

Your master password is never stored. If you forget it, your data cannot be recovered. That is what keeps it private.
Offline encrypted vault for passwords, photos, videos, notes and cards.
