Calculator Lock: Secret Vault

Calculator Vault – Private Photo & File Locker Behind a Real Calculator

Calculator Lock: Secret Vault disguises a secure media and file vault behind a fully functional calculator interface. Enter your secret PIN to access encrypted photos, videos, notes and documents stored only on your device. Key features include a photo & video vault, notes locker, document/file protection, intruder selfie capture on wrong PIN entries, and icon camouflage to stay hidden in plain sight.

This app works offline, doesn’t collect or share personal data, and uses military-grade encryption for privacy. On Android 11+ it requests All Files Access (MANAGE_EXTERNAL_STORAGE) so it can hide and restore files from any folder; uninstalling without restoring files will permanently delete them. Ideal for anyone who wants discreet, on-device protection for sensitive media and documents.
