HideMaster: Hide Apps Vault for Android

App overview

HideMaster — Hide Apps Vault is an Android privacy tool that intentionally looks like a regular calendar to avoid attracting attention. It creates an encrypted, private vault on your device where photos, videos and other files can be stored out of sight. Access is restricted to whoever knows the password or uses an enrolled biometric credential.

Privacy capabilities

• Keeps all protected items only on the device; nothing is uploaded to cloud services
• Unlocks the vault via fingerprint or facial recognition as well as a passcode
• Removes visible traces by hiding its launcher icon and excluding itself from the recent apps view
• Stores multiple media types and documents inside an encrypted container for organized, private access

Security and storage

The app emphasizes local, end-to-end protection: files are saved exclusively on your phone under strong encryption, which reduces exposure from remote breaches. Biometric unlocks (fingerprint and face) are supported for convenience, and the combination of a secret passcode plus stealth mode helps prevent casual discovery by others who might use your device.

Alternative option (free)

XAPK Installer — Free If you’re looking for another option related to app installation and management, the free XAPK Installer can be useful for sideloading apps and packages not obtained from an app store. It’s not a direct privacy vault, but it can complement workflows where you manage APK/XAPK files offline before installing them.
