Privacy Policy
This Privacy Policy explains how yunoktech ("we", "us") handles information in the Sudoku Play mobile app for Android (the "App"). By using the App you agree to this policy.
- You don't need an account. We never ask for your name, email or phone number.
- Your game progress, settings and statistics stay on your device. We don't receive them.
- The App shows ads from Google AdMob. Google may collect device identifiers and usage data to show and measure ads.
- Where the law requires it, you're asked for consent before ads are personalised, and you can change your choice at any time.
1. Information stored only on your device
To make the game work, the App saves the following on your device:
- Level progress, unlocked levels, stars and best times
- Your current saved games (board, notes, timer)
- Statistics, daily streaks and achievements
- Settings such as theme, sound, vibration and gameplay options
- A short technical error log if the App crashes
This information is not sent to us or to anyone else. It is deleted when you uninstall the App or use Settings → Reset all progress. Android may include it in your personal device backup, depending on your device settings; that backup is handled by Google under your Google account terms.
2. Advertising (Google AdMob)
The App is free and supported by ads provided by Google AdMob. To serve ads, limit how often you see them, measure their performance and prevent fraud, the Google Mobile Ads SDK may collect and process:
| Data | Purpose |
|---|---|
| Advertising ID and other device identifiers | Advertising, analytics, fraud prevention |
| IP address and approximate location derived from it | Advertising, analytics, fraud prevention |
| Device and app information (model, OS version, app version) | Ad delivery and measurement |
| Ad interactions (views, taps) | Advertising and analytics |
| Diagnostic data from the ads SDK | Performance and fraud prevention |
This data is collected and processed by Google, not by us. Learn more in How Google uses information from sites or apps that use its services and the Google Privacy Policy.
Optional "rewarded" ads give you an extra hint only if you choose to watch them.
3. Your choices
- Consent: In the European Economic Area, the UK, Switzerland and other places where it is required, the App shows a consent message (Google's User Messaging Platform) before personalised ads are used. You can review or change your choice at any time in Settings → Privacy choices.
- Advertising ID: You can reset or delete your advertising ID, or opt out of ad personalisation, in your device's Google or Privacy settings.
- Offline play: The game works without an internet connection. When you are offline, no ads are requested.
4. Permissions
The App itself needs no special permissions to play. The Google Mobile Ads SDK and Android libraries it includes add:
- Internet and network state – to load ads when you are online;
- Advertising ID (
AD_ID) – to show and measure ads; - Android ad services (Ad ID, Topics and Attribution APIs of the Android Privacy Sandbox) – privacy-preserving ad features you can control in your device's Privacy settings;
- Wake lock and foreground service – used internally by the SDK and Android libraries for short background tasks.
The App does not access your contacts, photos, camera, microphone, GPS location or files.
5. Children
Sudoku Play is a general-audience puzzle game and is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us and we will help remove it.
6. Data sharing and sale
We do not sell your personal information and we do not share it with anyone ourselves. The only third party that receives data from the App is Google, through the ads SDK described above.
7. Data retention and security
On-device data stays until you delete it or uninstall the App. Data handled by Google is retained according to Google's policies. Data sent by the ads SDK is encrypted in transit (HTTPS).
8. Your rights
Depending on where you live (for example under the GDPR in Europe, the UK GDPR, the CCPA/CPRA in California, or India's Digital Personal Data Protection Act), you may have rights to access, correct or delete personal data and to object to or limit certain processing. Because we do not hold your personal data, most requests are best handled through the in-app privacy choices and Google's controls, but you can always contact us and we will help.
9. Changes to this policy
We may update this policy from time to time. The new version will be posted on this page with a new effective date. Significant changes will also be noted in the App's release notes.
