S Keeper is an Android-based application developed by Sixmons that helps you securely manage your private photos. This free app is a perfect solution for those who use mobile banking and require high-level security for their personal photos. With S Keeper, you can view your photos in portrait or landscape mode, and also create memos and copy them conveniently.

One of the most significant features of S Keeper is its ability to encrypt your photos using AES encryption, a standard set by the US government. The app also allows you to transfer your photos from one device to another by performing a Google Drive backup and restore. However, to use this feature, you need to perform a backup on your old device and then restore it on your new device.

The app requires no essential access permissions, but it does require access to your storage and contacts for Google Drive backup and encryption purposes. It is recommended that you set up a password when you first launch the app. S Keeper is an excellent app for those who need to keep their private photos secure and accessible on their mobile devices.
