What is Calculator?
You screenshot something you'd rather keep private, then spend the rest of the day wondering if someone who borrows your phone will see it. Calculator - photo vault is a privacy and security tool that hides photos, videos, and files behind a working calculator interface that unlocks only with a numeric PIN.
The app looks and functions as a scientific calculator. Enter your PIN and tap the equals button to access the vault. Files stay encrypted with AES, with no cap on format or size. The inbuilt private browser lets you download images straight into the vault without leaving system traces, so your gallery and download history stay clean.
What stands out:
- Intruder Selfie captures a photo of anyone who enters the wrong password, so you know if someone tried to break in.
- The Fake Vault accepts a different PIN and shows decoy content, useful when you need to unlock under pressure.
- Shake Close exits the app instantly when you shake your phone, no fumbling with the home button.
- Fingerprint unlock skips the PIN step entirely, trading a few taps for biometric speed.
- AES encryption works on any file type or size, so you can lock documents and recordings alongside media.

The calculator panel doubles as the lock screen. Type your code, press equals, and the vault opens. If you forget your PIN, enter 11223344 and answer your security question to reset access. Restoring encrypted files takes a long press to enter edit mode, then a tap on the restore button. The app includes several color themes, but the mechanics stay the same across all of them.
Other photo vault apps
Keepsafe Photo Vault focuses on cloud backup and multi-device syncing, so your hidden media follows you across phones and tablets. LockMyPix also uses AES encryption and supports fake vaults, but stays local like Calculator - photo vault. The working calculator front and the private browser with direct-to-vault downloads set this one apart if you want both disguise and web access in the same tool.
This works for anyone who needs media locked away without obvious vault branding on their home screen. Keep in mind that files stay only on your device, so a factory reset or phone transfer wipes the vault unless you back up manually first. The app also contains ads and in-app purchases ranging from $0.99 to $14.99.
