Calculator Lock

Install the App: Download and install Calculator Lock from the Google Play Store. Set Up a Secret PIN: Open the app, and you will be prompted to set up a secret PIN code. This PIN will be used to unlock the hidden vault. Make sure to choose a code that only you will remember. Add Files to Your Vault: After setting up your PIN, tap the "+" or "Add Files" button to start adding your private photos, videos, or documents. These files will be securely stored in the vault and will not be accessible without the secret PIN. Hide Your Files: To hide files, simply select them from your gallery or file manager and choose the option to hide them in the app. Once hidden, the files will not appear in your normal phone storage and will only be accessible through the locked vault. Access Your Vault: To access your hidden files, open the Calculator Lock app and input your secret PIN. The app will unlock, allowing you to view, move, or delete your protected files. Use the Calculator: In case anyone tries to open the app, it will appear as a regular calculator until the correct PIN is entered. You can still use the app to perform basic calculations while keeping your vault discreet. Set Up a Fake PIN (Optional): If you’re worried about someone trying to break into your vault, you can set up a “fake PIN” to unlock a decoy vault with harmless content. This allows you to keep your real files secure while maintaining the illusion of the app being a simple calculator. Back Up and Restore: Make sure to back up your protected files regularly. Some versions of the app offer backup options to keep your files safe, even if you switch devices or need to reinstall the app.
