Welcome to MySudoku.com. We value your privacy and are committed to protecting your personal data. This Privacy Policy outlines how we collect, use, and safeguard your information when you use our website, games, and related services (collectively, the "Services"). Please read this policy carefully to understand our practices.

This Privacy Policy applies to MySudoku.com, a website delivering over 17 million unique Sudoku puzzles to players worldwide since 2016. For any questions, contact us at support@mysudoku.com.

We collect certain information ("Personal Data") to provide and improve our Services. This includes data you provide, data collected automatically, and data from third-party tools like Google AdSense and Google Analytics.

Data You Provide

• Contact Information: If you reach out via email or our support feature, we may collect your name and email address.
• User-Generated Content: Feedback or inquiries sent to us may include additional details you choose to share.

Data Collected Automatically

• Device Information: When you access MySudoku.com, we collect details like your device type, operating system, IP address, browser type, and unique device identifiers (e.g., Advertising ID).
• Usage Information: We track how you interact with our Services, including pages visited, time spent, puzzles solved, and ranking participation.
• Location: We infer your general location (e.g., country) from your IP address for analytics and ad personalization.

Data from Third Parties

• Google AdSense: To deliver personalized ads, AdSense collects data like your IP address and Advertising ID, governed by Google’s Privacy Policy.
• Google Analytics: We use Analytics to understand usage patterns, collecting data such as device info, session duration, and navigation paths, per Google’s Analytics Terms.

We use your Personal Data for the following purposes, based on legal grounds like contract performance, legitimate interests, or consent where required:

• To Provide and Enhance Our Services: Deliver 17M+ Sudoku puzzles, maintain ranking features, and sync progress where applicable (legal basis: contract performance).
• To Analyze and Improve: Gain insights into how players use MySudoku.com to optimize puzzles, fix bugs, and enhance user experience (legal basis: legitimate interests).
• To Serve Ads: Display personalized ads via Google AdSense to support our free Services (legal basis: legitimate interests or consent, depending on your region).
• To Communicate: Respond to your inquiries or support requests (legal basis: contract performance or consent).
• To Comply with Laws: Meet legal obligations, such as data retention regulations (legal basis: legal obligation).

Opt-Out Options:
- For ads, see "Opt-Out of Personalized Advertising" below.
- For analytics or communication, email us at support@mysudoku.com.

We share your data only as necessary to operate MySudoku.com:

• With Google:
  - AdSense: Shares data like IP address and Advertising ID with advertising partners to serve relevant ads (see Google’s partners list here).
  - Analytics: Processes usage data to provide us with performance insights.
• Service Providers: We use third-party hosting and support services to store and manage data securely.
• Legal Requirements: We may disclose data if required by law or to protect our rights, safety, or property.
• Business Transfers: If MySudoku.com undergoes a merger or sale, your data may be transferred as part of that process.

Cross-Border Transfers: Data may be transferred outside your region (e.g., to Google servers in the US), with safeguards like Standard Contractual Clauses ensuring compliance with GDPR where applicable.

We keep your Personal Data only as long as needed for the purposes outlined above:

• Service Delivery: Data like rankings or inquiries is retained while you use MySudoku.com.
• Analytics: Usage data is kept for up to 26 months (Google Analytics default) for performance analysis.
• Legal Obligations: We retain data as required by law (e.g., tax or fraud prevention purposes).

After this period, data is deleted or anonymized, meaning it no longer identifies you and cannot be used to exercise certain rights (e.g., access or erasure).

We and our partners (Google AdSense, Google Analytics) use cookies and similar tools:

• Essential Cookies: Enable core functionality, like puzzle navigation.
• Analytics Cookies: Track usage patterns to improve MySudoku.com.
• Advertising Cookies: Personalize ads based on your interests.

For details, see our Cookie Policy. You can manage preferences via our Google AdSense consent tool or browser settings. Note: We do not respond to "Do Not Track" browser signals.

Depending on your location (e.g., GDPR for EU, CCPA for California), you have rights over your Personal Data:

• Access: Request what data we hold.
• Rectification: Correct inaccurate data.
• Erasure: Delete your data, subject to exceptions (e.g., legal retention).
• Restriction: Limit how we process your data.

• Objection: Opt out of certain uses (e.g., ads or analytics).

Personalized Advertising:

• Via AdSense Tool: Adjust settings in our consent popup.
• Device Settings:
  - iOS: Settings > Privacy > Tracking > Disable "Allow Apps to Request to Track".
  - Android: Settings > Google > Ads > Enable "Opt out of Ads Personalization".
  Opting out switches to non-personalized ads; you’ll still see ads, but not tailored to you.

Analytics: Email support@mysudoku.com to opt out of Google Analytics tracking.

MySudoku.com is for users aged 16+ (or higher per local laws). We do not knowingly collect data from children under 16. If you believe we have such data, contact us at support@mysudoku.com to request deletion.

Our Services may link to external sites (e.g., Google policies). We’re not responsible for their privacy practices – review their terms before engaging.
