This policy explains what happens to your data when you play Ferroll ("the app"), published by Mustafa Yağız ("we", "us"). It applies to the iOS app distributed on the Apple App Store and to the Android app distributed on Google Play.
In short: we do not run any servers and we do not collect, store or receive any personal information about you. Your game progress never leaves your device. The only third parties involved are Apple (on iOS) and Google, described below.
Your unlocked levels, stars, best times, remaining lives, life refill timer and your sound, music and haptics settings are saved locally on your device, using the platform's standard app storage on iOS and the app's private storage on Android. This data is not transmitted anywhere, we cannot read it, and it is deleted when you delete the app.
The app reads your device's accelerometer to steer the ball. This reading is used only in the moment to move the ball on screen. It is never recorded, stored or transmitted.
The free version of the app shows ads through Google AdMob. To deliver and measure those ads, Google may collect information such as your device's advertising identifier, IP address, device type and your interactions with ads. We never see this data ourselves; it is handled by Google under its own policies.
In the European Economic Area, the United Kingdom and Switzerland, the app shows Google's consent form before any ads are requested, on both iOS and Android. You can change your choice at any time from Settings → Privacy Options inside the game.
iOS The app also asks for your permission before any tracking identifier can be used. If you decline, you will still see ads, but they will be non-personalised. You can change this choice at any time in iOS Settings → Privacy & Security → Tracking.
Android Ads may use your device's advertising ID. You can reset or delete it in your device settings (on most devices Settings → Privacy → Ads, or Settings → Google → Ads). Once deleted, you will still see ads, but they will not be personalised.
Buying the "Remove Ads" in-app purchase stops the app from requesting the full-screen ads between levels. Optional rewarded videos, which you can choose to watch for a free life, are only requested when you open a screen that offers one.
Google's handling of this data is described in the Google Privacy & Terms and the AdMob policies.
If you are signed in to the leaderboard service on your device, your Endless mode score is submitted to the Ferroll leaderboard so it can be ranked against other players. On iOS this is Apple Game Center; on Android it is Google Play Games. The name shown on the leaderboard is the one set in your Game Center or Play Games profile — not something the app creates. You can opt out by signing out of Game Center (iOS Settings) or Google Play Games (the Play Games app); the game remains fully playable.
Purchases are processed entirely by Apple through the App Store on iOS, and by Google through Google Play Billing on Android. We never receive or store your payment card details, billing address or account credentials. The app is only told whether a purchase succeeded.
When the main menu opens, the iOS app asks Apple's public App Store lookup service whether a newer version of Ferroll is available. This request contains only the app's own identifier. No information about you is sent.
| Permission | Why the app uses it |
|---|---|
| Internet and network state | Load ads, process purchases, submit leaderboard scores and detect when you are offline |
| Vibration | Haptic feedback when the ball hits walls or collects gems (can be turned off in Settings) |
| High sampling rate sensors | Read the motion sensor fast enough for smooth tilt controls |
| Advertising ID | Used by Google AdMob to deliver and measure ads, as described above |
The app never asks for your location, contacts, photos, microphone or camera.
| Category | Collected? |
|---|---|
| Name, email or account details | No — the app has no accounts or sign-up |
| Location | No |
| Contacts, photos, microphone, camera | No — the app never requests them |
| Health or fitness data | No |
| Analytics or crash reporting by us | No — we run no analytics service |
| Game progress | Stored only on your device |
Ferroll contains no chat, no user-generated content and no social features beyond the leaderboards described above. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will act on it.
Because we hold no personal data about you on any server, there is nothing for us to export or erase on request. If you would still like to ask about your data, contact us as described below and we will respond.
If this policy changes, the revised version will be posted on this page with a new "last updated" date. Significant changes will also be noted in the App Store and Google Play release notes.
