A simple privacy policy for a deliberately simple app.

Kanji no Ma is designed to keep your study data on your device. This page explains what the app does not collect, what limited technical information may be processed to deliver this website, and how to contact us if you have any questions.

Last updated: April 22, 2026

No account You can use the app without signing in.

No ads The app does not display advertising.

No in-app analytics We do not run analytics or tracking SDKs in the app.

On-device progress Your quiz progress and bookmarks stay on your device.

1. Scope

This Privacy Policy applies to the Kanji no Ma iOS application and this informational website. If you follow a link to the App Store or another third-party site, that service's own privacy policy will apply once you leave our pages.

2. Information We Collect in the App

We do not ask you to create an account, and we do not knowingly collect personal information through the app.

Study-related data generated by the app, such as quiz progress, wrong-answer history, bookmarks, and streak-related records, is stored locally on your device using Apple's on-device storage frameworks. We do not transmit that study data to our own servers.

In plain terms: your learning history stays on your device unless you choose to remove it by deleting the app or your device data.

3. Website Delivery

When you visit this website, our hosting provider may process limited technical data that is commonly required to serve a web page, such as your IP address, browser type, device information, and request logs.

We use that hosting infrastructure only to deliver the site and maintain basic service security and reliability. We do not use this information for advertising or behavioral profiling.

4. Third-Party Services

The app does not include third-party analytics, advertising, or tracking SDKs. This website may link to third-party services such as Apple's App Store or your mail application when you choose to open them.

Those services operate independently and are governed by their own terms and privacy policies.

6. Children's Privacy

Kanji no Ma is intended for learners of Japanese and does not knowingly collect personal information from children. Because the app does not require an account and does not collect personal information through in-app tracking, it is designed to be safe for a broad audience.

7. Retention and Deletion

App data remains on your device until you remove it. You can delete locally stored app data by uninstalling the app or clearing device data through Apple's operating system controls.

Website-related server logs, if any, are retained only as needed by the hosting provider for operations and security.

8. Changes to This Policy

We may update this Privacy Policy from time to time to reflect app changes, legal requirements, or operational updates. If we make changes, we will post the revised policy on this page and update the "Last updated" date above.
