Privacy Policy
Calm Sort is developed by lei cao ("we"). This policy explains what data the app handles and why.
What we collect
- Usage analytics (Google Firebase Analytics): anonymous gameplay events such as level start/complete, hints used, and screen views, plus device identifiers used by Firebase. We use this to understand how the game is played and improve it.
- Crash reports (Firebase Crashlytics): technical crash data (stack traces, device model, OS version) to fix bugs. Not linked to your identity.
- Advertising data (Google AdMob): when ads are shown, Google's SDK may use your device's advertising identifier to serve and measure ads. On iOS we ask permission via App Tracking Transparency first; in regions covered by GDPR we show Google's consent form (UMP) before any ads load. After the one-time "Remove Ads" purchase the app shows no ads at all.
What we don't collect
No accounts, no names, no emails, no contacts, no location, no photos, no messages. Your level progress, stars, and daily streak are stored only on your device. The app has no backend.
Purchases
The one-time "Remove Ads" purchase is processed entirely by Apple App Store / Google Play. We never see your payment details. Removing ads removes every ad in the game, including optional rewarded ads.
Your choices
- Decline tracking in the iOS permission prompt — the game works identically.
- Change ad-consent choices anytime in Settings → "Manage privacy consent".
- Remove all ads permanently via the in-app purchase.
Children
Calm Sort is not directed at children under 13 and does not knowingly collect personal information from them.
