Burrow: Private Photo Vault

Burrow keeps your private photos, videos, files and notes encrypted on your phone, behind a PIN, pattern or password only you know.

Private, on this phone
• No internet permission at all: Burrow itself can't connect to the internet. Check it under "App permissions" below.
• No account, no ads, no tracking.
• We can't see your files and we can't reset your PIN.

Strong, honest security
• Every file is encrypted with modern, well-tested cryptography (XChaCha20-Poly1305), with a tamper check on every piece.
• Your PIN is made slow to guess (Argon2id) and tied to a key inside this phone.
• File names, dates and thumbnails are encrypted too. On disk there are only random names.
• Screenshots and screen recording are blocked inside Burrow.
• A built-in Privacy self-check checks that nothing readable is stored.

Never locked out
• 12 recovery words, shown once at setup, open your vault if you forget your PIN.
• Encrypted backup to a file you keep, on another phone, a computer or Google Drive. Automatic weekly backup if you want it.
• Fingerprint unlock, free for everyone.

Everything in one place
• Import photos and videos, then remove the originals from your gallery.
• Private camera: photos and videos go straight into the vault.
• Notes, folders, full-screen viewer and smooth video playback.

Decoy vault, free
• A second vault with its own PIN. Show the decoy, keep the real one hidden.

Burrow Pro (one payment, no subscription)
• Unlimited items (free holds 300).
• Up to 16 vaults.
• Duress PIN: opens the decoy and destroys the other vaults.
• Disguised icon: Burrow can look and work like a calculator.

Encryption, fingerprint unlock, recovery and backups are free. We never sell safety.

Honest limits: if you forget your PIN and lose your 12 words, nobody can open your files, including us. Laws about destroying data differ between countries; you're responsible for how you use the duress PIN.
