Calculator Lock - Photo Vault

Calculator Lock - Photo Vault is a private Android vault behind a working calculator. Use it as a calculator photo vault for personal photos, videos, audio, PDFs, files and Secure Notes inside encrypted app-private storage. To unlock it, simply enter your 4-digit PIN and press the equals (=) button.

A real calculator entry
The app opens as a working calculator. Vault access stays completely hidden—just type your matching PIN on the calculator pad and tap the equals (=) button to enter.

• Different PINs can open different vaults.
• Keep content separated without a visible session switcher.

Private media and file vault
Import from Gallery or Files. Organize content by type: Photos, Videos, Audio, PDF and Files.

• View photos, videos and audio in the app.
• Preview PDFs inside the vault.
• Unlock, export or share other files when in-app preview is not supported.
• If your goal is to hide photos or videos from normal gallery browsing, import them into the vault and remove originals when Android and the source app allow it.

Secure Notes
Create encrypted text notes for private reminders, ideas and personal details.

• Search notes.
• Pin important notes.
• Edit notes, move them to Trash and restore them when needed.

Albums and Trash
Use built-in folders for Photos, Videos, Audio, PDF, Files and Restored. Pro users can create custom albums. Deleted media and notes go to Trash, where you can restore them or delete them permanently.

Vaults, Pro extras and privacy controls
Enjoy up to 2 personal vaults for free, and smoothly secure your files using our optimized, batch-by-batch importing.

Pro removes in-app ads and unlocks unlimited vaults, larger bulk imports, custom albums, custom auto-lock timing and optional Intruder Detection. Intruder Detection requires camera permission.

Calculator Lock uses screenshot protection and clipboard cleanup on sensitive flows. Core calculator disguise, encrypted vault storage, media import, file storage, PDF preview and Secure Notes are available without Pro.

Important privacy notes
Vault content is designed for local encrypted app-private storage. It can leave the vault when you export, share, unlock to device, copy text, open an external PDF link, contact support or choose another app.

Free users may see ads. Google Play, Firebase, AdMob, UMP and configured ad partners may process service, consent, purchase, diagnostic or ads-related data as described in the privacy policy.

Calculator Lock does not provide cloud backup or PIN recovery. Imported originals may still exist outside the vault unless you choose deletion and Android or the source app allows it.

If you forget a PIN, clear app data, uninstall the app, lose the device or remove encrypted files, vault access or content may be lost.
