Preferences and study progress
The site stores your language, theme, and Kanji review progress in your browser's local storage. This information stays in that browser and is not attached to a learner account. Clear this site's browser data to remove it; progress may be lost when you do.
Editor accounts and submissions
Public study does not require an account. Restricted editing tools require an editor account and use essential session and security cookies. If you submit a correction, the account name, submission time, proposed changes, and any reviewer note are stored so editors can review and audit the change.
Third-party services
The site currently loads fonts from Google Fonts. Your browser contacts Google to retrieve those fonts, so Google may receive technical request information such as your IP address and browser details. Review Google's privacy information for its handling of that request.

Server and security logs
Like most websites, the hosting server may process request and security information such as IP address, requested URL, time, and browser details. The exact data and retention period depend on the hosting provider and deployment configuration.
Analytics and advertising
The site does not currently include advertising or third-party analytics trackers. If these services are added, this policy should be updated before they are enabled.
Questions or requests
For questions about this policy or a request concerning editor-submission data, contact the site operator through the contact channel published with this service. Browser-stored study progress can be removed using your browser's site-data controls.
This policy describes the current implementation and is not legal advice. Requirements may vary depending on where the service and its users are located.
