Privacy Policy

Last updated: September 26, 2026

This Privacy Policy explains how minnanihongo.com ("we", "us", or "the Site") collects, uses, shares, and protects information when you visit or use our services.

Information We Collect

When you create an account, we collect your email address and profile information you choose to provide (such as display name or avatar). When you use lessons, quizzes, JLPT mock tests, and vocabulary review, we store learning progress, scores, and study activity linked to your account. If you are signed in, we also record how long you actively use the Site (visible-tab time on learning and browsing pages) so we can improve the product and identify learners who may need more support.

We also collect standard technical data through cookies and similar technologies, including browser type, device type, pages visited, and approximate usage patterns.

How We Use Information

We use your information to provide and improve the learning experience, maintain your account, save quiz results, send account-related emails (such as email verification), fix technical issues, and understand how the Site is used so we can improve content and features. Signed-in usage time is first-party product analytics (not sold) and does not depend on Google Analytics cookie consent.

We may also use information to display relevant advertisements through Google AdSense and Adsterra.

If you opt in, we may send occasional emails with study-resource recommendations. Those emails link to pages on this Site; product clicks may go to partner stores (affiliate). You can turn this off in Profile or via the unsubscribe link in each email. We do not send these emails unless you opt in.

Cookies and Local Storage

The Site uses cookies and similar technologies for authentication (keeping you signed in), language preferences, and advertising. You can control cookies through your browser settings. Disabling cookies may limit features such as staying logged in.

Advertising (Google AdSense and Adsterra)

We use Google AdSense to display advertisements on public pages of the Site. Google and its advertising partners may use cookies or similar technologies to serve ads based on your visits to this Site and other websites. You can learn more and opt out of personalized Google advertising at Google Ads Settings. Google's privacy policy is available at policies.google.com/privacy.

We also use Adsterra to display banner advertisements on public pages. Adsterra and its partners may use cookies or similar technologies. Adsterra's privacy policy is available at adsterra.com/privacy-policy.

How We Share Information

We do not sell your personal information. We share data only with service providers that help us operate the Site (hosting, email delivery, advertising) under their respective privacy policies, or when required by law.

Data Security

We implement appropriate technical and organizational measures to protect your data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet is 100% secure.

Your Rights

Depending on your location, you may have the right to access, correct, or delete your personal data. You can update profile information in your account settings, request account deletion through the delete-account flow, opt out of personalized ads via Google Ads Settings, and contact us at vjsoft.contact@gmail.com with privacy questions. We may update this policy from time to time; continued use of the Site after changes means you accept the updated policy.
