Takken — Exam Prep
Privacy
Last updated: September 18, 2026
Takken — Exam Prep (the “app”) is an iOS study app provided by zheng weng (the “developer”). It is designed not to collect personal information. It is unofficial study material, not an app from the examination body.
1. Information collected
The app does not collect or transmit any personally identifiable information. No account registration is required.
- The selected exam year, study progress, mock-exam records and study plan are stored only on your device using native local data storage. They are not sent to the developer’s server; the developer does not operate a server.
- Questions and statute texts are bundled with the app. Opened statute text is displayed on your device.
- There are no advertising, analytics or tracking SDKs.
- Network access is used to open public pages from Japan’s Ministry of Land, Infrastructure, Transport and Tourism and the Real Estate Transaction Improvement Organization in your browser and for App Store purchases and restoration using Apple’s purchase framework. The developer does not relay this communication.
- Apple handles payments; the developer does not receive card numbers or other payment information.
2. Device features
| Feature | Purpose | Data handling |
|---|---|---|
| Calendar | Write study-day events to the dedicated Takken Drill calendar only when you choose Add to Calendar | Events remain in the system calendar and are not sent to the developer’s server. You can delete them in the calendar app |
| Notifications | Remind you of today’s study only when you enable on-device reminders | Local notifications only; no remote push notifications. Off by default |
| Network | Links to public materials, purchases and restoration | Communication does not pass through the developer’s server |
| In-app purchase | Unlock questions in all four areas, all memorization cards and further mock exams (one-time ¥680) | Apple processes purchases; the developer does not retain payment information |
The camera, microphone, location, contacts and photo library are not used.
3. Deleting data
Progress and study plans are on your device. Deleting the app also deletes them. Purchase entitlement can be restored using Restore Purchases, but progress cannot be recovered from the cloud. Events written to the calendar can be deleted in the calendar app.
4. Changes
This page will be updated if the policy changes.
