Privacy and saved progress
Nihongo Fighting Room works without an account. Practice progress is saved only in the browser on the device you are using.
What stays in your browser
Session results, internal streak history, personal bests, placement results, preferences, and unlocked badges use local browser storage. They are not synchronized to an account or cloud database. Clearing browser data, changing devices, changing browsers, or using a private window can remove them. The home screen shows only whether practice was completed today, not a multi-day streak.
Names on downloadable badges
The name you type is drawn into the badge image in your browser. The app does not save or upload that name. Request the PNG download before refreshing or closing the page, then choose where to keep the file. Share image is enabled only when the browser can hand the PNG to a share destination. Post on X requests the PNG download and opens a prepared text post; you attach the image yourself.
Hosting, analytics, and feedback
The hosting service can process standard request information such as an Internet Protocol address, browser type, and requested page. Cloudflare Web Analytics measures aggregate page use and performance, including page path, referrer host, country, browser, and device type. It does not receive typed answers, badge names, feedback text, email addresses, internal content identifiers, or saved progress from this app. A separate feedback form receives only the information you choose to submit to that form.
