Hide it Pro vs Valv

Hide it Pro is an app for keeping private photos, videos, music, apps and notes out of view. Hidden data is encrypted and stored on the device, and the privacy policy says the maker cannot access media added to the app. Users can access the vault with a fingerprint, and app locking supports a fingerprint or password. The app also includes a private browser with ad blocking and tracking protection, plus chat for private conversations and photo exchange. Optional plugins add more functions: one can remove the app icon, while VBrowser offers incognito browsing, a download manager, video downloads from over 14 streaming sites and picture saving. An SMS hider plugin is described as early development and is not guaranteed to work. Hide it Pro is available for Android, iOS, macOS and Windows. Its free plan is listed at free, with no paid plans listed on the official site. The privacy policy says third-party ad SDKs may collect IP address, device and operating-system details, session data and diagnostics.

Valv is a free Android gallery vault for storing photos, GIFs, videos, and text files in encrypted form on a device. Files can be arranged into folders, with notes or text attached, and separate vaults can use different passwords. Access supports a password or PIN; one vault can also be unlocked with fingerprint or face authentication. Valv uses ChaCha20 encryption and derives keys with PBKDF2 and HMAC-SHA512. PBKDF2 uses 50,000 iterations by default, and that count can be changed. Encrypted files remain on local storage, supporting backups and transfers between devices, but cloud backup is not available. The project README says the app requires no permissions, while Google Play declares no data collected and no data shared with third parties. Valv requires Android 9.0 or newer and is listed at free. It is distributed through Google Play, F-Droid, and a GitHub APK, under GPL-3.0-only.
