How we use your information

Sharing

We do not sell your personal data. Your data is stored with our backend service providers (Firebase and Supabase), who process it only to provide the app's functionality to you, under their own security and confidentiality standards. Advertising data is handled by Google AdMob as described in the Advertising section below.

Advertising

The Free mock tests in the app show ads provided by Google AdMob. Premium users with an active package do not see ads. To show and measure ads, AdMob may collect and use your device's advertising ID, IP address, and device and app-usage information, and may use cookies or similar technologies. Where required (for example in the European Economic Area and the UK), the app asks for your consent before showing personalized ads. You can reset or delete your advertising ID, or opt out of ad personalization, in your Android device settings (Settings → Google → Ads). To learn how Google uses data from apps that use its services, see policies.google.com/technologies/partner-sites. Ads are never shown during an exam.

Data retention and deletion

You can delete your account at any time from Settings → Security → Delete Account inside the app. This permanently removes your profile and account data. Your mock test results may be retained afterward for academic record-keeping, but are no longer linked to your identity or usable to sign back in.

If you'd prefer to request deletion without using the app, see our Account Deletion Request page.

Security

All data in transit is encrypted (HTTPS/TLS). Access to backend data is restricted by authentication and access-control rules on our backend services.

Children's privacy

Nihongo Mock Test is intended for learners preparing for adult professional and academic Japanese-language exams and is not directed at children.

We may update this policy from time to time. Material changes will be reflected by updating the date at the top of this page.
