The User Interface in this game is made using HTML,
The website backend does not keep data in persisted storage as none is needed for Single and Community modes.
Every match session expires after a certain period of time (between 1 and 24 hours after inactivity).
However, for the coming advanced features (not yet implemented), session data will be stored during the feature's life cycle only.

Enjoy the game!
