Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 5.56 MB, so it installs quickly even on modest connections.
This build is signed by "SECUSO - Security Usability Society" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Privacy Friendly Solitiare is a Klondike Solitaire Game. Its goal is to move all cards to the foundations. A detailed description of the rules can be found in the app's help site.

Which features offers Privacy Friendly Solitaire?

Privacy Friendly Solitaire provides different difficulty levels that draw either one or three cards from the deck. Additionally there are the following versions of counting points:
- None: No points are counted.
- Standard: The Player starts with zero points, moves give different points.
- Vegas: The Player starts at -52 points and tries to get more than zero points, while the deck can only be passed through one time.

The Player can generate an automatic move by clicking the Hint-Button or automatically move all possible cards to the foundation by shaking the device (if it is activated in the Settings).
Addtionally he can undo and redo moves. Optionally he is shown the time of play.
When the game is almost won (meaning that there are no more cards turned face-down), it will finish automatically.
