Calculator Lock - Photo Vault

Calculator Lock is a unique and practical application that allows users to create separate private vaults for their photos, videos, audio, and documents. These vaults are protected by a 4-digit PIN, which can be accessed by long-pressing the 5 key on the calculator. This ensures that only the user can access their private content.

The app functions as a normal calculator, but without the correct PIN, it remains a calculator and does not reveal the hidden vaults. Inside the vaults, users can import content from their Gallery or Files, organize items with albums, and even keep deleted files in a separate Trash folder before permanently removing them.

One of the core privacy features of Calculator Lock is its encrypted app storage on the user's device. This ensures that all content within the vaults is secure and cannot be accessed by anyone else. Additionally, the app offers screenshot protection and clipboard cleanup on sensitive flows, as well as auto-lock protection with customizable timing for added security.

The app also offers multiple private vaults, each with its own unique PIN, allowing users to keep different types of content in separate vaults. The Pro version of the app unlocks unlimited vaults and custom albums for even more organization options.

It's important to note that all content within the vaults stays on the user's device and only leaves when the user chooses to export or share it. Users also have the option to keep their original files or delete them from their public gallery for extra privacy. This, combined with the fact that the PIN is only known to the user, ensures that the vaults remain private and secure.

In summary, Calculator Lock is a practical and secure way to protect personal media behind a familiar calculator interface. With its various privacy features and customizable options, users can feel confident that their private content will remain safe and secure within the app.
