What data is processed, why, and with whom

Effective date: 7 November 2026

Cross Math Metro needs no account. Your progress, coins and settings stay on your phone. Data leaves your phone only when an ad is shown or when you make a purchase.

This policy explains the personal data processed when you use the Cross Math Metro mobile app (iOS and Android), under the Turkish Personal Data Protection Law No. 6698 (KVKK) and, for users in the European Economic Area, the General Data Protection Regulation (GDPR).

2. What stays on your phone

Your level and stars, coins, daily puzzle history, streak, statistics and settings are stored only on your phone. They are not sent to us.

3. Ads

From level 12, every third “Next level” shows a full-screen ad between levels; not if you bought Remove ads. You can also choose to watch a short ad for one life, a hint or 25 coins; only you start those. No ad appears on its own during play. Ads are served by Unity Ads and ironSource Ads through Unity LevelPlay (Unity Technologies and ironSource).

Before the first ad you answer “How should ads work?”: Allow personalized ads or Use general ads only. No request is sent to the ad network before you answer.

How Unity processes data is described in the Unity privacy policy.

4. Purchases

For coin packs and Remove ads, payment is taken by the App Store (Apple) or Google Play (Google). We never see your card details. RevenueCat (RevenueCat, Inc., USA) is used to verify purchases and for “Restore purchases”. RevenueCat receives: an anonymous user ID created by the app, purchase and transaction details (product, date, store transaction number), country, platform and app version. Your name and email are not sent to RevenueCat.

5. When you write to us

If you email us through “Write to us”, we use your address and message only to answer you and solve the problem. Your phone’s operating system version is added to the email; you can see and delete it before sending. The rating window is Apple’s or Google’s own; the store handles any rating you give.

6. What we don’t use

Cross Math Metro has no account and no separate analytics or crash reporting tool. It asks for no location, contacts, photos, camera or microphone access. We do not sell your personal data.
