Sudoku Classic
Privacy Policy
Data collected by third-party services
We have no servers of our own that receive your data. The game contains the following SDKs from Google, which process data on our behalf:
- Google AdMob (advertising). Shows a full-screen ad between puzzles (never while you are solving one) and an optional video ad you can choose to watch to get an extra hint. AdMob may collect the advertising ID, app instance ID, IP address (used to estimate approximate location), device and OS information and ad interactions to show ads, limit how often they appear, measure them and prevent fraud. Personalised ads are shown only if you allow them.
- Google Analytics for Firebase (analytics). Records gameplay events — for example screens opened, puzzles started and solved, difficulty, solve time, mistakes, hints used and ads shown — together with the app instance ID, device model, OS version and approximate country. We use it only to improve the game.
- Google User Messaging Platform (consent). Shows the consent form where required and stores your choice on the device.
- Google Play in-app updates and in-app review. Let Google Play offer an update or a rating dialog inside the game. We do not receive your review or personal data from them.
Data is sent encrypted (HTTPS) and handled under Google's Privacy Policy; see also how Google uses information from apps that use its services. Analytics data is kept by Google for a limited period (up to 14 months) and then deleted.
Consent and your choices
In the European Economic Area, the UK and Switzerland the game asks for your consent (Google's consent form, IAB TCF v2) before ads or analytics store or read anything on your device. Until you answer, Google Analytics runs in Consent Mode v2 with all storage denied. You can change your choice at any time with the Privacy button on the game's main screen. Everywhere, you can reset or delete your advertising ID or opt out of personalised ads in Android settings (Settings → Google → Ads, or Settings → Privacy → Ads).
Data stored on your device
Your best times and number of solved puzzles, your unfinished game, the sound setting, how many times the app was opened and whether the rating dialog was already shown are saved only in the app's private storage on your device. They are removed when you clear the app's data or uninstall the game.
Deleting your data
Clear the app's data in Android settings or uninstall the game to delete everything stored on the device. To request deletion of analytics data, e-mail [email protected] — details on the data deletion page.
Permissions
The game uses the internet and network-state permissions to load ads and send analytics, and the advertising ID permission added by the Google Mobile Ads SDK. It does not access your contacts, photos, files, camera, microphone or precise location.
Children
The game is not directed at children under 13 and we do not knowingly collect personal data from them.
Changes
If this policy changes, we will update this page and the "Last updated" date before the new version of the game is released.
