Information stored on your device
Kanji Flash stores quiz progress such as score, EXP, level, streak, questions answered, and accuracy in localStorage. This data stays in your browser and is used to keep the quiz state between visits.
You can remove this progress by clearing site data for Kanji Flash in your browser settings.
Shared devices
If you use Kanji Flash on a shared computer, another person using the same browser profile may see the saved quiz progress. Use a private window or clear site data if you do not want progress to remain on that device.
Server and hosting data
Kanji Flash is a static website. Like most websites, hosting and CDN providers may process technical request logs such as IP address, URL, user agent, timestamp, and error data for security, delivery, and diagnostics.
Kanji Flash does not sell personal data and does not run an account database for the current preview.
External links
Kanji Flash links to septn.com, Jepang.org, and related ecosystem sites. Those external sites may have their own privacy practices and policies.
If the site later adds analytics, accounts, or server-side learning history, this policy should be updated before or alongside that change.
