Frequently asked questions

How do I restore my purchases?

Tap "Restore Purchases" at the bottom of the Shop screen. Premium and subscription entitlements come back through your store account (just be signed in with the same Apple/Google account).

How do I cancel the 2x Speed subscription?

Subscriptions are managed by your store account: iOS — Settings → your name → Subscriptions → Kristalis; Android — Play Store → Profile → Payments & subscriptions → Subscriptions. Cancel at least 24 hours before the period ends to avoid renewal.

I saw an inappropriate player name — what can I do?

Tap the name on the leaderboard → ⚑ Report (reaches us; reviewed within 24 hours) or 🚫 Block (the name is hidden from your view immediately). We apply zero tolerance to inappropriate names.

How do I delete my data?

The only data stored on our server is your leaderboard profile (nickname + scores). To delete it: Settings (⚙) → "Delete leaderboard profile" → confirm. Your profile, scores and endless record are permanently deleted from the server. Local game progress on your device is removed when you uninstall the app. You can also send the same request by email.

How do I turn off notifications?

You can disable Kristalis notifications in system settings; in-game vibration can be turned off in Settings → Vibration.

I lost my progress / changed device

Game progress is stored locally on your device; there is no cloud save yet. Keep this in mind before uninstalling. Purchases are tied to your store account and can always be restored.
