Privacy Policy
Koofunnel (クーファンネル) ("we") sets out below how user information is handled in the game "GENKAI ICHIGEKI" (web, iOS and Android versions; the "Game").
1. Information we collect
We do not collect personally identifiable information such as your name or email address. There is no account registration.
2. Data stored on your device
Game records such as personal bests, the collection, titles and play counts are stored only on your device (browser local storage or the app's storage). They are not sent to our servers, and they are deleted when you clear your browser data or uninstall the app.
3. Advertising
The Game may use third-party advertising services (web: Google AdSense; apps: Google AdMob). These providers may use cookies or advertising identifiers (IDFA / Advertising ID) to show ads based on your interests.
- How Google uses information: How Google uses information from sites or apps that use our services
- You can turn off personalized ads in Ad Settings. In the apps, you can limit the use of advertising identifiers in your device settings.
4. Result images for sharing
When you use "Post on X" or "Send on LINE", the result image generated by the Game (only the numbers and drawing of your result) is stored on our server and a result-specific URL is issued, so that social networks can show it in the link preview. The image contains no personally identifiable information. Anyone with the URL can view it, and it is deleted automatically after about 90 days.
To prevent abuse, the sender's IP address is converted into an irreversible hash and recorded only for a short time (about 10 minutes).
5. Play counts
To build the "popular" list on our website, when you start playing we send only which game was played and on which day to our server. To avoid counting the same person twice, your IP address and browser type are converted into an irreversible hash, used for that day only and discarded the next day. No personal information such as your name is sent. We do not use any other analytics tools.
6. Sharing
Sharing your results happens only through your own action, via your device's share feature or social networks. We do not receive the content you share.
7. Changes
We may update this policy as needed. The updated policy takes effect when it is posted on this page.
8. Contact
