physiprac Privacy Policy

Effective date: October 13, 2026
App: physiprac (com.mawatarishoji.physiprac)
日本語

physiprac(the "App") teaches mechanics through diagrams and simulation puzzles. So that middle and high school students and other children can use it safely, the App is designed not to collect users' personal information.

1. Personal Information

The App does not collect personal information from anyone, including children.

• It does not ask for your name, email address, age, school, location, or similar information, and there is no account or sign-in.
• It does not use the camera, microphone, photos, or contacts.
• No analytics or behavior-tracking tools (analytics SDKs) are used.
• No ads are shown, and no advertising SDKs are included. No data is provided to advertisers.
• Your learning progress is never sent off your device.

2. For Parents and Guardians

The App has no features for interacting with other users (no chat, posts, or rankings). Children are never asked to enter their name or to share anything with us. We accept questions by email; if a child wishes to contact us, we ask that they do so together with a parent or guardian.

3. Data Stored on Your Device

Solved puzzles, hint steps, settings, and which news items you have read are stored only on your device. We cannot access this data. It is not synced with iCloud. Deleting the App also deletes the data from your device. If device backups are turned on, the data is included in those backups.

4. In-App Purchases

If we offer a paid plan (subscription) in the future, purchases will be processed through Apple's In-App Purchase system. Payment, renewal, and cancellation are managed by Apple through your Apple Account, and we do not receive credit card or other payment details or information that identifies you. We will update this page before such a plan becomes available.

5. News Data and Notifications

To show announcements, the App retrieves a static news file from mawatarik.com. This request contains none of your progress and no user or device identifier, and the downloaded data is used only to display news. Like any website, the server that delivers this file (https://mawatarik.com/apps/physiprac/news.json) keeps standard access logs (such as IP address and time). These logs are used only to operate the service and not to identify users.

If you turn on news notifications in Settings (off by default), the App retrieves the same news file using iOS background refresh and shows a local notification on your device when there is a new announcement. No push notification server is used, and no device token is sent.

6. External Links

News and the support page may include links to websites. Information on those sites is handled according to their own privacy policies.

7. Changes to This Policy

Any changes to this policy will be published on this page. If a new feature changes how information is handled, we will update this page before that feature becomes available.

8. Contact
