Last Updated: August 16, 2024

Welcome to Sudoku Zen. This Privacy Policy is provided by YOONGOO KANG (referred to as "we", "us", or "our"), and it's meant to help you understand what information we collect, why we collect it, and how you can manage it.

1. Information We Collect

Our primary goal is to provide you with a great gaming experience. The information we collect depends on whether you play as a guest or create an account.

  • For Registered Users: To create an account, we collect your email address and create a username (derived from your email). We store your game records (best times per difficulty), hint points, and user ID on our secure Firebase servers. This allows you to access your progress across devices.
  • For Guest Users: We do not require you to provide any personal information. Your best time is stored locally on your device using your browser's local storage and is not transmitted to our servers.
  • Information for Advertising: To keep the game free, we partner with third-party advertising networks. These partners may collect and process data to provide personalized ads, which may include: device identifiers, IP address, general location data (e.g., country or city), device information, and information about your interactions with ads.

2. How We Use Your Information

We use the collected information for the following purposes:

  • To provide, operate, and maintain our Game.
  • To save your records and personalize your game experience.
  • To serve personalized and non-personalized advertisements to support the Game financially.
  • To allow for competitive rankings between registered players.
  • To comply with legal obligations and prevent misuse.

3. Data Sharing with Third Parties

To support our Game, we display ads from third-party partners like Google. These partners may use cookies and other identification technologies to collect data for ad personalization. We do not share your personally identifiable information like your email with them, but non-identifiable data like your player name may appear in public rankings.

For more information on how Google handles your data, you can review their policies: Google's Privacy & Terms.

4. Your Choices and Rights

You have control over your information.

  • Clearing Local Data: You can delete your guest statistics at any time by clearing your browser's cache and site data for our Game.
  • Managing Account Data: Registered users can contact us to request the deletion of their account and associated data.
  • Opting Out of Personalized Ads: You can opt-out of personalized ads by using the privacy settings on your device. For mobile devices, this is typically located in your device's "Settings" app under "Privacy" or "Ads".

5. Children's Privacy

Our Game is designed for a general audience and does not knowingly collect personal information from children under the age of 13 (or the relevant age in your jurisdiction). If you are a parent or guardian and believe we have inadvertently collected such information, please contact us so we can promptly take steps to remove it.

6. Changes to This Privacy Policy

We may update this privacy policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify you of any changes by posting the new policy on this page and updating the "Last Updated" date.
