Gymnos Smart Vault: Auto Hide is a smart and secure vault app that helps you hide delicate photos and videos on your Android phone. The app automatically detects any sensitive or nsfw media on your device and sorts and shows you the photos or videos present in your phone gallery that are delicate in nature. You can choose to hide them or delete them from your gallery.

One of the best things about this app is that it does not back up data to a server or cloud, which means your data never leaves your phone. Gymnos can only be opened with your fingerprint or PIN, making it secure and safe to use. The app comes with a minimalistic yet elegant user interface for easy navigation. You can also schedule Gymnos to run automatically at a later point in time, say when the phone is idle.

However, there are some limitations to the app. It does not support SD card or external storage, there is no PIN recovery, and you cannot recover hidden media if you uninstall the app.

Overall, Gymnos Smart Vault: Auto Hide is a useful app for those who want to keep their private photos and videos safe and secure on their Android phone. Contact the developer at for any assistance you may need.
