Privacy Policy for MySudoku
Last updated: September 15, 2026
```This Privacy Policy describes how MySudoku, provided by Nir Barzilay, handles information when you use the MySudoku mobile application.
MySudoku is a premium Sudoku puzzle game. The App does not display advertisements and does not offer in-app purchases or subscriptions.
The App is designed to minimize the collection of personal information. Some information may nevertheless be processed by the App or by third-party services used to provide optional functionality, analytics, synchronization, or platform services.
Who We Are
For the purposes of this Privacy Policy:
- "App" means the MySudoku mobile application.
- "We", "us", or "our" means Nir Barzilay.
- "You" means the person using the App.
- "Service Providers" means third-party companies whose services or software may be used by the App.
Information We Collect
MySudoku does not require you to create an account and does not ask you to provide your name, email address, telephone number, password, or payment information in order to play the game.
Depending on the features you use and the configuration of the App, the following information may be processed.
Gameplay and App Data
The App may store information required to provide its gameplay features, including:
- Puzzle progress
- Difficulty selection
- Daily challenge progress
- Completion status
- Solve times
- Mistakes
- Hint usage
- Notes and gameplay preferences
- Statistics
- Achievements
- Theme and application settings
This information is primarily stored locally on your device so that the App can provide its functionality and preserve your progress.
iCloud Synchronization
If iCloud synchronization is enabled and supported by the App, certain gameplay and application data may be synchronized through Apple's iCloud services.
This may include information such as game progress, statistics, achievements, settings, daily challenge progress, and other information required to synchronize your experience between your Apple devices.
iCloud is an Apple service. Information stored or synchronized through iCloud is subject to Apple's applicable terms and privacy practices.
Analytics
The App may use Firebase Analytics, provided by Google, to understand general usage of the App and help us improve its functionality, stability, and user experience.
Depending on the configuration of the App, analytics information may include:
- App launches and sessions
- General interactions with the App
- Game-related events
- Daily challenge usage
- Hint usage
- Settings interactions
- App version and build information
- Device type and operating-system version
- Technical and diagnostic information
Analytics information is used to understand how the App is used, identify problems, and improve performance, reliability, and gameplay.
Local Notifications
If you grant notification permission, the App may schedule local notifications, for example to remind you about a Daily Challenge.
Local notifications are controlled by iOS. You can disable notification permission at any time through your device settings.
Game Center
If Game Center functionality is enabled and you choose to use it, Apple may process information associated with your Game Center account, achievements, leaderboards, or other Game Center functionality.
Game Center is an Apple service and its processing of information is governed by Apple's applicable privacy practices.
Feedback and Support
If you choose to contact us by email, you voluntarily provide the information contained in your message, including your email address and any information you choose to include.
We use this information to respond to your request, provide support, investigate issues, and improve the App.
Advertising
MySudoku is completely ad-free.
The App does not use Google AdMob, Google Mobile Ads, advertising networks, advertising SDKs, or other third-party advertising services.
We do not use information collected through the App to display advertisements or to create advertising profiles.
In-App Purchases and Payments
MySudoku does not currently offer in-app purchases, subscriptions, paid upgrades, or other purchases within the App.
The App therefore does not directly collect or process credit-card, debit-card, or other payment information.
App Tracking
MySudoku does not use advertising or other cross-app tracking technologies for advertising purposes.
The App does not use an advertising identifier for targeted advertising. No advertising consent or App Tracking Transparency permission is required solely for the purpose of using MySudoku.
How We Use Information
Information processed by the App or its service providers may be used to:
- Provide and maintain the App
- Save and restore gameplay progress
- Synchronize supported data through iCloud when enabled
- Provide Daily Challenges
- Provide statistics and achievements
- Provide optional notifications
- Provide Game Center functionality where enabled
- Understand general App usage
- Identify and diagnose technical problems
- Improve gameplay, performance, stability, and usability
- Respond to support requests
- Maintain the security and integrity of the App
- Comply with applicable legal obligations
Third-Party Services
The App may use third-party services that process information according to their own privacy policies and terms.
- Google Firebase Analytics: https://firebase.google.com/support/privacy
- Google Privacy Policy: https://policies.google.com/privacy
- Apple Privacy Policy: https://www.apple.com/legal/privacy/
Third-party services may process information on servers located in countries or regions outside your country of residence.
Sharing of Information
We do not sell your personal information.
We may allow third-party service providers to process information where reasonably necessary to provide the functionality described in this Privacy Policy, including analytics, cloud synchronization, platform services, and technical diagnostics.
We may also disclose information where reasonably necessary to:
- Comply with applicable laws or legal processes
- Protect our rights, property, or security
- Prevent fraud, abuse, or other unlawful activity
- Protect the safety of users or others
- Defend against legal claims or liability
Your Choices
You can control certain privacy-related features of the App:
- You can disable notifications through iOS settings.
- You can control iCloud functionality through your Apple device and iCloud settings.
- You can choose whether to use Game Center functionality where available.
- You can uninstall the App to remove locally stored App data from your device.
Information stored by Apple through services such as iCloud or Game Center may need to be managed through your Apple account or Apple's privacy tools.
Data Retention and Deletion
Locally stored gameplay and settings data generally remains on your device until you delete it, reset it using available App functionality, or uninstall the App.
Information synchronized through iCloud may remain in iCloud according to Apple's services, retention practices, and your iCloud account settings.
Analytics and technical information processed by third-party service providers may be retained according to those providers' applicable retention policies and legal obligations.
Because MySudoku does not maintain its own user account system, we generally do not maintain a database containing your name, email address, or other directly identifying account information.
Security
We take reasonable measures to minimize unnecessary data collection and protect information processed by the App.
However, no electronic storage or transmission method can be guaranteed to be completely secure. We therefore cannot guarantee absolute security of information.
Children's Privacy
MySudoku is a general-audience Sudoku game and is not specifically directed toward children.
We do not knowingly collect directly identifying personal information from children through the App.
If you believe that a child has provided personal information to us, please contact us so that we can review the situation and take appropriate action where required by applicable law.
International Data Processing
Some third-party service providers used by the App may process information on servers located outside your country of residence.
Such processing is subject to the applicable privacy practices, contractual protections, and legal requirements of the relevant service providers.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time, including when the App's functionality or the third-party services it uses change.
When we make changes, we will update the "Last updated" date at the top of this Privacy Policy. The updated policy becomes effective when it is published.
