Calculator Photo Vault is a mobile application that allows users to hide their private files, including photos, videos, and other documents, on their phones. The app is designed to look like a regular calculator, but it has a secret vault where users can store their files. To access the vault, users need to enter a numeric PIN on the calculator panel. The app offers several features, including AES encryption, an inbuilt private browser, shake close, intruder selfie, fake vault, fingerprint unlock, colorful theme, and calculator.

One of the top features of Calculator Photo Vault is the vault, which allows users to encrypt their files using the AES encryption algorithm. There are no restrictions on file format or size, and users can even take pictures and record videos directly within the app. The app also has an inbuilt private browser that allows users to browse the web safely and download photos directly into the vault. Additionally, users can quickly close the app by shaking their phone, and the app will automatically take a selfie of anyone who enters the wrong password.

Another feature of Calculator Photo Vault is the fake vault, which allows users to create a fake vault with a different password to store fake photos and videos. The app also offers fingerprint unlock, which allows users to use their fingerprint to unlock the app. Users can choose from a variety of fashionable colors to create their own theme, and the app also functions as a regular and scientific calculator. If users forget their password, they can enter a specific number into the calculator and answer a security question to retrieve it.

Overall, Calculator Photo Vault is a useful app for anyone who wants to keep their private files safe and secure on their phone. The app offers several features that make it easy to use and customize, and users can contact the developers if they need help or have any questions. However, users should be aware that their files are stored only on their device, so they should back them up before transferring to a new device or factory resetting.
