In our games we use various identification systems: custom ID, temporary session ID or login/pass systems.
All that is needed to provide you two things: web / online highscore option and online gaming mode - multiplayer.
These data are stored in secured database, on server protected by firewall and anti-virus software.
No other company, person, third party entity has ability to read them, and these data wont be used for any marketing purposes.
In any time you want, your identification data can be deleted.
Such request need to be send from one of our games on mobile device. Each game has 'Privacy Policy' page, and there you can find 'Delete Info' button.
