JLPT Study does not require an account. We do not collect personal information such as your name or email address. Your study progress and preferences (like theme choice) are stored locally in your browser using localStorage and are never sent to our servers.
When you use the reading or translation exercises, the text you submit is sent to a third-party AI service (Groq) to generate responses. We do not store these requests or responses on our servers. Please review Groq's privacy policy for details on how they handle data.
We use Google AdSense to display advertisements. Google may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings.

We may update this policy from time to time. Changes will be posted on this page with an updated date.
