This privacy policy describes how the Matchy Matchy mobile game (“the app”, “we”, “us”) handles your information.
When you play Matchy Matchy we collect the following:
| Data | Purpose | Stored where |
|---|---|---|
| Anonymous user identifier (uid) generated by Firebase Authentication | Identify your device across sessions so your scores and nickname stay attached to you | Google Firebase |
| Nickname you enter on first launch | Displayed next to your score on the leaderboard | Google Firebase (Firestore) + locally on your device |
| Score you achieve in each game mode | Displayed on the leaderboard for that mode | Google Firebase (Firestore) + locally on your device |
| Nickname history every time you change your name | Audit trail so we can investigate abuse or impersonation if needed | Google Firebase (Firestore), private to your uid |
We do not collect: your email, phone number, real name, contacts, location, device identifiers beyond Firebase’s anonymous uid, or any data that would identify you as a real person.
A single banner ad is shown on the Game Over screen, served by Google AdMob. The app requests non-personalized ads only (requestNonPersonalizedAdsOnly: true). Google may use limited device information (general region from IP, OS version, language) to deliver a relevant ad, but does not build a cross-app profile of you for advertising. The app does not request the iOS App Tracking Transparency identifier (IDFA) and does not use the Android Advertising ID for personalised tracking. Ads are subject to Google’s privacy policy.
No other third-party SDK ships with the app.
Matchy Matchy is intended for general audiences. We do not knowingly collect data from children under 13.
You can clear your local data at any time from the in-app Reset my data option in the nickname screen. This signs you out, deletes the local nickname and best scores, and generates a new anonymous identity on next launch. Your previous score rows in Firestore are not automatically removed — to permanently delete them, contact us at the email below with the uid shown in the app and we will remove the row within 30 days.
Questions or removal requests: genji.games08@gmail.com or open an issue.
By using Matchy Matchy you consent to the data practices described in this policy.
