You can create your PIN to encrypt a file or a directory by AES 256-bit encryption algorithm. Multiple PINs can be created for different file or directory.
This app never lists or shows up your PINs. It is your responsibility to remember all your PINs. It is designed as this way so that you can keep some files or directories secret if someone you love checks your phone and you don't need give all PINs out since no one else knows how many PINs you have.

There are so many accounts or password to remember in modern life. You can put the account and password clue in a text file then encrypts it by a PIN you are choosing so no one can view it. You can view it just simply open this app and enter the PIN relating to that file. Then you can view edit and encrypt it again in this app.

If you have some private photos videos and documents don't want anyone else to find and open them in your phone/tablet so just create a PIN to encrypt them and hide them. You can copy move and delete files within this PIN directory in this app.

The encrypted text file can be backed up/restored to/from Google Drive so that you never lost your secrete information.
