Privacy Policy

Kanji Monster (the “Service”) can be used with only a nickname and a recovery code, without any email address or password. The Service collects and stores the following information.

• Nickname and recovery code (stored as a hash, never in plain text)
• Study session records (level, grid size, correct/incorrect answers, points earned)
• An anonymous identification cookie stored in your browser

The Service may use Google AdSense to display advertising, and third-party advertising vendors, including Google, may use cookies to serve ads based on your interests. You can opt out of personalized advertising through your browser settings or Google Ads Settings.

The information collected is used only to provide and improve the Service and to calculate rankings, and is not shared with third parties except as required by law.

This policy may be changed without prior notice depending on how the Service is operated.
