Nicko privacy policy
Last updated: October 26, 2026
This policy explains what information the Nicko app uses and why. Nicko is made by Devrim Çatak ("devca", "we"), who is responsible for the processing described here.
The short version
- Nicko has no account and no sign-up. We don't ask for your name, email or phone number.
- What you enter in the app (player names, colors and avatars, your own game rules, games, hands and scores, game nights, statistics and settings) stays on your phone. We never receive it.
- The free version shows ads from Google AdMob. Personalised ads are only shown if you agree.
- We use Google Firebase to see how the app is used and to fix crashes.
- We don't sell your personal information.
Information stored on your phone
Your player names, colors and avatars, your own game rules, games, hands and scores, game nights, statistics and settings are saved only in the app's storage on your device. Deleting the app deletes them. If you use Export data in Settings, the app creates a backup file and you choose where it goes (for example Files or a message to yourself); we never receive it.
Services that receive data
Nicko uses the following services. Each acts as our processor or as an independent controller under its own policy.
| Service | Data | Why |
|---|---|---|
| Google Firebase Analytics | How the app is used (screens opened, games started and finished, settings chosen), an app instance ID, device model, OS version, language and approximate country | Understanding which features help and fixing what doesn't |
| Google Firebase Crashlytics | Crash reports: device model, OS version, app version and what the app was doing when it crashed | Finding and fixing bugs |
| Google Firebase Remote Config | An app instance ID | Adjusting settings (for example how often ads appear) without an app update |
| Google AdMob | Advertising ID (only where you allow it), IP address, approximate location derived from it, device and app information, ad interactions | Showing ads in the free version, measuring them and preventing fraud |
| RevenueCat | A random app user ID, purchase receipts and purchase history from Apple or Google | Unlocking the paid upgrade and restoring it on a new phone |
Ads, consent and tracking
- EEA, UK and Switzerland: the first time you open the app, a consent form from Google lets you choose whether your data can be used for personalised ads. You can change your choice any time in Settings → Privacy choices.
- iPhone: the app asks for permission to track (App Tracking Transparency). If you say no, your advertising ID is not shared and ads are not personalised. You can change this in iOS Settings → Privacy & Security → Tracking.
- Android: you can reset or delete your advertising ID in Settings → Privacy → Ads (or Google → Ads).
- US state privacy laws: showing personalised ads may count as "sharing" for cross-context behavioural advertising. You can opt out by declining personalised ads or tracking as described above. We do not sell personal information for money.
If you buy the paid upgrade, ads are turned off.
Legal bases (EEA/UK)
We rely on your consent for personalised ads and tracking; on our legitimate interest in keeping the app working, secure and improving for analytics, crash reports and non-personalised ads; and on performing our contract with you for purchases.
How long data is kept
Data on your phone stays until you delete it or the app. Data held by the services above is kept under their retention settings; we keep analytics data for no longer than 14 months.
Your rights
Depending on where you live, you may have the right to access, correct, delete or restrict the use of your personal data, to object to its use, to data portability and to withdraw consent. Because Nicko has no account, we usually can't link data to you; most choices are made in the app or your phone's settings as described above. You can also email us, and you may complain to your local data protection authority.
Children
Nicko is not directed at children under 13, and we do not knowingly collect personal information from them.
International transfers
The services above may process data outside your country, including in the United States, under safeguards such as the EU Standard Contractual Clauses.
Changes
If this policy changes, we will update the date at the top of this page and, for important changes, tell you in the app.
