Ludixa privacy policy

Last updated: November 4, 2026

Ludixa is a logic games app (Sudoku, Minesweeper and Word search) for Android. This policy explains what data the app uses, where it stays and what you can do with it.

Summary

• There are no accounts or sign-in, and the app has no server of its own: your progress stays on your phone.
• The app shows Google AdMob ads. Google receives device data to show and measure them, as explained below.
• You can delete your progress from the app at any time.

Who is responsible

Gonisoma, developer of Ludixa. Contact: nicolas.jorqueramartinez@gmail.com.

Data the app stores on your phone

So you can keep playing, the app stores on the phone:

• Your games: game, level, result, time and date; games in progress; your streak, the challenge calendar, achievements and statistics.
• Your settings: language, theme, text size, colorblind palette and each game's options.
• Ad counters: how many puzzles you completed and when the last ad was shown, to respect the frequency limits.

This data is not sent to any server of ours.

Backups

• Android automatic backup: if it is turned on, Android may copy this data to your Google account and restore it on a new phone. Google manages it, and you can turn it off in Android settings.
• Export progress: in Settings › Data and privacy you can save a file with your progress wherever you choose, and import it later. The app doesn't send that file anywhere.

Ads (Google AdMob)

The app uses Google AdMob to show ads: a banner on some screens, at most one full-screen ad every few puzzles and, if you ask for it, a video in exchange for a hint or to undo your last tap in Minesweeper. To show and measure them and to prevent fraud, Google's SDK collects from the device, among other things:

• the Android advertising ID;
• the IP address and general device data (model, Android version, language);
• how you interact with the app and the ads (for example, opening the app, taps and videos watched);
• diagnostic data about the performance of the app and the SDK (for example, launch time).

Google handles that data under its own policies: how Google uses information from apps that use its services.

• Consent: where the law requires it (for example, in the European Economic Area, the United Kingdom and Switzerland), the app shows Google's consent form before requesting personalized ads. You can change your choice in Settings › Data and privacy › Privacy options.
• Advertising ID: you can delete or reset it in Android settings (Privacy › Ads).
• Content: the app asks Google for ads suitable for teens at most.

Android permissions

• Internet and network state: only for ads. The games work offline.
• Advertising ID and Android advertising features (Privacy Sandbox): used by the Google AdMob SDK.

Children

Ludixa is meant for people aged 13 and over and is not directed at children under 13. That's why the app asks Google for ads suitable for teens at most.

If you are a parent or guardian and a child under 13 uses the app, you can uninstall it to delete everything it stores on the phone, and write to the contact email.

How to delete your data

• Settings › Data and privacy › Reset all progress deletes your games, streak, calendar, achievements and statistics.
• Uninstalling the app deletes everything it stores on the phone. Android's automatic backup is managed from your Google account.
• For the data Google receives through ads, see Google's policy linked above.

Questions and data deletion

You can write to us to ask what data the app uses or to request its deletion:

• The app has no accounts and doesn't keep your data on servers of its own: we can't see or remotely delete what's on your phone. You delete it from the app or by uninstalling it, as explained above.
• The data Google receives through ads is managed by Google. You can review it, delete it or limit personalized ads in My Ad Center and in your Google account.

For any question about this policy, write to nicolas.jorqueramartinez@gmail.com.

Changes

If the app changes how it uses data (for example, by adding analytics), this page will be updated before that version is released, with a new date at the top.
