Privacy Policy

A1. Data and purposes

Applications process data needed for their features. Depending on the type of application, this can include:

• local content, settings, notes, saved games and progress;
• network and connection information for features that inspect or manage networks;
• technical information needed for compatibility, troubleshooting or update checks;
• information you voluntarily provide when requesting support.

Processing data on your device and sending it to the developer or an external provider are different activities. Accessing data to operate a feature does not, by itself, mean that the data is transmitted off your device.

The specific types of collected and shared data must also be described in the application’s explanations and its Data safety section on Google Play.

A2. Permissions

Required permissions depend on the application’s features and the Android version. An application must explain the purpose of access to sensitive data before using it.

On some Android versions, location permission can also be necessary to access certain wireless-network information. The permission’s name alone therefore does not establish whether an application records a route or transmits location.

You can manage permissions in Android settings. Refusing or withdrawing a permission may limit the feature that requires it.

A3. External services, diagnostics and advertising

The use of external services differs between applications. A service is not included in a particular application merely because it is mentioned in this shared policy.

Where actually integrated, external services can include:

• Google services for distribution and feature operation;
• Firebase Crashlytics for technical crash reporting;
• Google AdMob for displaying advertisements.

An application using such a service must clearly identify the provider, purpose and types of data the service receives. Information about Google’s data practices is available in the Google Privacy Policy.

We do not sell user data. The use of data for advertising or other additional purposes must be separately disclosed and, where required, depend on the user’s consent.

A4. Specific information for Sudoku for Android

The verified Sudoku for Android version 4.25 stores games, progress, notes, statistics, settings and learning progress locally. It does not include the AdMob advertising SDK or Firebase Crashlytics.

The application uses an internet connection for automatic or manual update checks. It retrieves available-version information from a public resource hosted on GitHub. During the network connection, the host can receive your IP address and ordinary technical request information. Update checks do not send saved games, notes or statistics.

GitHub handles network information under its privacy statement.

Archive exports and log sharing are initiated by the user. Android or the selected provider manages any system backups according to the user’s settings.

A5. Retention and deletion on Android

You can remove local data by clearing the application’s data in system settings or uninstalling the application.

Resetting an individual feature, such as statistics, does not necessarily delete all application data.

Exported files, copies already shared and system backups must be managed separately with the provider or at the location where they are stored.

B1. Data collection

Sudoku for iOS does not send personal information, device information or gameplay data to the developer. It has no advertising, analytics, tracking or automatic crash-reporting service. No account is required.

B2. Local storage and backups

Saved games, progress, notes, move history, spent hints, statistics, learning progress and settings are stored in the app's space on your device. iOS manages any system backups according to your settings. The app does not operate its own cloud-sync service.

B3. Import and export

You choose whether to import or export a progress archive. Exports are saved to the location you select in Files, which may be an external or cloud-storage provider. That provider handles the file under its own terms. An exported archive contains gameplay data and should be shared only with people you choose. Android-compatible exports do not preserve every iOS-only setting or recovery copy; use the native iOS backup for a complete local backup.

B4. Retention and deletion

Local progress remains until you replace it or delete the app. Reset statistics clears the current statistics; it is not a full data-deletion action. To remove the app's local data, choose Delete App in iOS, rather than Offload App. Copies you exported or kept in system backups must be managed separately in Files, your storage provider or the relevant iOS backup settings.

B5. System timer

The app uses systemUptime to measure playing time, inactivity and time between events within the app. These values are used for timers, not to identify your device or track you. The privacy manifest declares Apple's approved reason 35F9.1 for measuring elapsed time and enabling timers.

B6. Optional diagnostics and support

Developer logging is optional and stored locally. A log is shared only when you choose Share log and a recipient in the system share sheet. You can clear it with Clear log. If you contact support, the message and information you choose to provide are used to answer your request. Please do not send passwords or unrelated personal information. Contact: mangona.net@gmail.com.

B7. External websites and updates

Website and email links open only when you select them. The website, browser, email service, Apple and any storage provider you select operate under their own privacy practices. This iOS section describes Sudoku for iOS; it does not describe the data practices of other Mangona apps. Changes to the app's practices will be reflected in an updated policy and privacy declarations.

C1. Support and voluntarily provided information

If you contact us, we receive your email address, message and any attachments you choose to send. We use this information to handle your request and investigate the reported issue.

Support correspondence may be retained for up to two years. You can request deletion using the contact address below, subject to any applicable legal retention obligations.

C2. Security

We limit access to information we receive to handling its intended purpose. We use appropriately protected network connections where network transmission forms part of an application’s operation.

No storage or transmission method guarantees complete security. When exporting or sharing files, check the selected destination and recipient.

C3. Your rights

Where data-protection law applies, you may, subject to its conditions, request access, correction, deletion, restriction of processing or data portability, and object to certain processing. Where processing relies on consent, you can withdraw that consent.

Send requests to mangona.net@gmail.com. You can also lodge a complaint with the competent data-protection authority. Further information about GDPR rights is available from the European Commission.

You can also manage data that remains solely on your device or with a storage provider you selected through the relevant device or provider settings.

C4. Children

If a parent or guardian believes that a child has provided personal information to us, please contact us. We will investigate the request and remove the information where appropriate under applicable obligations.

C5. Changes to this policy

We update this policy when features or data practices change. We identify the last-updated date when publishing changes. Where a change requires a new notice or consent, we provide it before beginning that processing.
