This policy explains what data is processed when you use the game Logical Crossing (Android and iOS apps, and web version), why, and how to exercise your rights.
1. Who is responsible?
The app is published by Boniface Consulting. For any question about your data: contact@bonifaceconsulting.fr.
2. What we do not collect
The game requires no account, no name, no email address. We have no server receiving your game data; the app's usage statistics are sent to Google (section 5). Purchases are handled by Google Play or the App Store (section 6).
3. Data stored on your device
To work, the game stores only on your device: the chosen language, the "Auto ✗" setting, the "Usage statistics" setting, the list of solved puzzles, the number of hints available and the number of puzzles solved during the day (used to schedule ads). It also stores the number of hint videos watched during the day (at most 7 per day) and, if you make a purchase, whether the "No ads" option is active and the identifiers of the purchases already delivered. This data is not sent to us. It is deleted with the app (or, for the web version, by clearing the site data in your browser).
4. Advertising (Android and iOS apps)
The app is free and funded by advertising provided by Google AdMob (Google Ireland Limited / Google LLC). A full-screen ad may be shown between two puzzles, and a video you choose to watch gives you a hint (rewarded ad). The web version shows no ads.
If you buy the "No ads" option (section 6), full-screen ads between puzzles are no longer shown. Videos that give a hint remain available if you choose to watch them, so the Google Mobile Ads SDK and the consent form described below are still used.
To show and measure ads, the Google Mobile Ads SDK included in the app may process:
- device identifiers: Android advertising ID, or IDFA on iPhone if you allow it, and app-specific identifiers;
- IP address and an approximate location derived from it;
- technical information: device model and operating system, language, app version;
- interactions with ads (impressions, clicks) and diagnostic data.
This data is processed by Google under its own policies: Google Privacy Policy and How Google uses information from sites or apps that use its services.
5. Usage statistics (Android and iOS apps)
To understand how the game is used and improve it, the app sends statistics to Google Analytics for Firebase (Google Ireland Limited / Google LLC): screens shown, puzzles started, solved or abandoned (level, duration, number of moves, undos and hints), hint videos watched, tutorial opened, settings changed, shop visits and in-app purchases (product, price, currency). This information is tied to a random installation identifier, never to your name or email address; the SDK also processes the IP address (for an approximate location), the device model and operating system, the language and the app version. It is not used for advertising, and the advertising identifier is not collected by Analytics. The web version sends no statistics.
In the European Economic Area, the United Kingdom and Switzerland, the installation identifier is stored only if you accepted, in the consent form, the storage of information on your device. You can turn these statistics off at any time in Settings › Privacy › Usage statistics. Google keeps this data for at most 14 months.
6. In-app purchases (Android and iOS apps)
The app offers optional purchases: the "No ads" option and packs of hints. Payment is handled entirely by Google Play (Google Ireland Limited) or the App Store (Apple Distribution International Ltd.), with your store account, under their own terms and privacy policies. We never receive your card or bank details, your name or your email address.
After a purchase, the store tells the app which product was bought, with a transaction identifier; the app keeps this information on your device only, to deliver the product once and to restore the "No ads" option (Shop › Restore purchases). Google and Apple send us sales reports (for example the order number, the product, the country and the amount), which we keep for our accounting obligations. Hints are stored on your device only and are lost if you uninstall the app.
7. Your consent
- European Economic Area, United Kingdom, Switzerland: on first launch, a consent form (Google User Messaging Platform, IAB TCF compliant) lets you accept, refuse or choose purposes. If you refuse, non-personalised or limited ads may be shown.
- iPhone: the app asks, through Apple's prompt, for permission to access the advertising identifier (IDFA). You can change this at any time in Settings › Privacy & Security › Tracking.
- Change your choice: in the game, Settings › Ads › Privacy choices. On Android you can also delete or reset your advertising ID in the device's Google settings.
8. Legal bases
Personalised advertising, access to device identifiers and storage of the statistics identifier rely on your consent. Showing non-personalised ads and preventing ad fraud rely on our legitimate interest in funding a free game, within the choices expressed in the consent form. Usage statistics rely on our legitimate interest in improving the game, and you can turn them off in the settings. In-app purchases rely on the performance of the contract (delivering what you bought) and on our legal obligations (accounting).
9. Transfers outside the European Union
Google may process data outside the European Union, in particular in the United States, with the safeguards provided by the GDPR (standard contractual clauses, EU-U.S. Data Privacy Framework).
10. Retention
Data stored on your device stays there until the app is uninstalled. Retention of advertising data is set by Google in its privacy policy. The sales reports received from Google and Apple are kept for 10 years (accounting obligations).
11. Children
The game is intended for a general audience and is not designed for children under 13. We do not knowingly collect data about children.
12. Your rights
You have the right of access, rectification, erasure, objection, restriction and portability, and the right to withdraw your consent at any time. Since we hold no data about you, most requests are handled directly with Google or through the settings described above; you can also write to contact@bonifaceconsulting.fr. You may lodge a complaint with your data protection authority (in France, the CNIL).
13. Changes
This policy may change, for example when new features are added. The update date is shown at the top of the page.
