FFFFOUND Desktop is an Adobe AIR application that brings the joy of FFFFOUND to your desktop through an original interface.
It allows you to manage a list of your favorite users, sign in and mark items you love. Just like on the website you can choose to see either users' findings or posts, browse suggested images, favorites users and followers...
I made this app on my own and am not affiliated with FFFFOUND in any way. I am using FFFFOUND's name and logo with Keita Kitamura's permission.

Your username/email and password are not stored anywhere if you don't check "Remember me", I swear. If you do they're stored in the EncryptedLocalStore.
