If you want to keep your game progress, you need to close the game properly.
- Make sure that you saved your progress in the game (where this option is available)
- Click on the Exit button in the game, wait for the Boosteroid desktop to appear.
- Close the browser tab (not a gaming launcher if it appears), or press the combination of Control + Alt and click on [X]
- At this point, your gaming achievements and progress will be sent to the server and stored there until you get back to the game next time.
Subject to availability of some technical problems (such as network load) on the side of gaming platforms, there may be disruptions in the transfer of game saves to the cloud storage of gaming platforms (e.g. Steam). The Boosteroid service does not store user data.
