Local data such as stats are stored locally on the user device using Chrome Storage Sync or localstorage if the users opts in.

Data Sharing
All in game statistics (high scores and games played) will be accessible to other users, accompanied by a random id and username (this can be opted out of).
Error reports can be optionally (opt in not opt out) shared with Arcade Classics.
