JLPT Study Room (“the app”, “jlpt.win”) is a study website for JLPT and Business Japanese (BJT) learners. This policy explains what information is handled when you use it.
Your progress, settings, text size, theme, and learned-word marks are saved in your browser’s local storage on your own device. This data stays on your device. We do not receive or copy it to our servers.
The app does not require an account and does not ask for your name, email, or phone number to use the free content. The hosting provider (Cloudflare) may keep standard server logs (such as IP address and request time) as part of normal web hosting and security.
If you buy an unlock, payment is handled by the payment provider (PayPal). We do not see or store your card or payment account details.
The app does not use advertising cookies. If we add analytics later, this policy will be updated before it is turned on.
You can delete all local data at any time with the “Delete my data” link in the footer, or by clearing your browser’s site data.
The app is a general study tool and is not directed at children under 13.
We may update this policy. The date at the top shows the latest version.
