Privacy policy
Last updated: 18 October 2026
This policy explains what data Ather - City Control processes, on Android and iOS, and how you can control it.
1. Data controller
Ivan Cesari. For any question about your data you can write to ivancesaridev@gmail.com.
2. You can play without a Google account
Ather - City Control can be used without signing in: in that case we create an anonymous guest profile (a random identifier, with no email or name) and save your progress on our servers under the username you choose. Without linking an account, though, you won't be able to recover it on another device or after reinstalling the app.
3. If you sign in with Google
We use Firebase Authentication to let you sign in with your Google account (or to link it to your guest profile, which keeps its progress). We receive your email address, name and profile picture: the email is visible only to you on the Profile screen, while your Google account name is not stored on our servers. Leaderboards only show the nickname you choose, which you can change at any time and which doesn't have to contain your name.
4. Game data
We save your progress, both as a guest and with Google: scores, matches played, mission outcomes, unlocked achievements, in-game currency and items, unlocked content, daily and weekly rewards, selected team. This lets you pick up your game on any device and makes the leaderboards work.
5. Leaderboards
The nickname, score and date of your best matches are visible to other signed-in players in the global and weekly leaderboards.
6. Diagnostics and statistics
We use Firebase Crashlytics and Performance Monitoring to know whether the app crashes or is slow, and Google Analytics to understand, in aggregate form, how the game is used (which screens are visited, which missions succeed). These tools collect technical identifiers of the installation, device model, operating system, language and approximate location derived from the IP address. We don't use advertising, we don't track your activity across other apps or websites, and we don't sell your data.
7. Notifications
If you allow notifications, we send you a weekly alert when the leaderboard restarts. You can revoke the permission from your device settings.
8. Security
We use Firebase App Check to verify that requests come from the genuine app and to prevent score tampering. Communications are encrypted (HTTPS) and the progress saved on the device is protected by the operating system's mechanisms.
9. Where your data is
Our backend services run in Europe (europe-west3, Frankfurt). Some Google services (authentication, statistics, diagnostics, notifications) may involve transfers to the United States, covered by the Standard Contractual Clauses and by Google's participation in the EU-U.S. Data Privacy Framework.
10. How long
We keep your account data for as long as the account exists. Crash reports are kept for 90 days, technical logs for 30 days, event-level statistical data for 2 months and user-level data for 14 months.
11. Your rights
You can ask at any time to access your data, correct it, delete it, receive it in a readable format, restrict or object to its processing, and withdraw any consent given. Write to ivancesaridev@gmail.com: we reply within 30 days. You can also lodge a complaint with the Italian Data Protection Authority (Garante per la protezione dei dati personali, www.garanteprivacy.it).
12. Deleting your account
You can delete your account (including a guest profile) and all linked data from Profile → Delete account: we immediately remove your profile, username, scores and leaderboard entries. Alternatively, write to ivancesaridev@gmail.com: we take care of it within 30 days. With Profile → Unlink account you can instead remove your Google account and your email while keeping your progress on this device.
13. Children
The game is not intended for children under 13 and we don't knowingly collect their data. If you believe a child has given us data, write to us and we'll delete it.
14. Changes
If we change this policy we will publish the new version at this address and update the date at the top; for significant changes we will let you know in the app.
