The onboarding we refused
Many free game sites ask for an email before the first round. That is convenient for the company and expensive for the player: another password, another inbox, another identity fragment. BrainBounce Arcade is built so a guest can play immediately. Favorites, personal bests, XP, coins, streaks, and life counters are written to localStorage in this browser.
The cost is obvious. A new phone does not inherit the old scores. Clearing site data is permanent. We describe that in the privacy policy because a feature that cannot survive a cache-clear should not be advertised as a cloud profile.
What this design protects
Guest-first progress means we do not need a child account, a public username, or a friends list to make a high score feel real. It also means we are not storing your play history on a server just to show you a number you already earned. Advertising partners still operate under their own policies; local scores are not a substitute for reading the privacy notice.
If you want a ritual that survives devices, keep a note of a favorite game and a practice goal. The number in the HUD is a local souvenir. The skill is what actually transfers.
