Privacy Policy — 日本語能力試験対策
Last updated: 18 September 2026
「日本語能力試験対策」(“the App”) is an iOS app provided by zheng weng (“the Developer”) for studying JLPT N2 and N1. It is designed not to collect personal information. It is unofficial study material, not an app from the exam administrators.
1. Information collected
The App does not collect or send personally identifiable information. There is no account.
- Level, next test date, study progress, mock records, study plans, and display language stay on your device (SwiftData). They are not sent to the Developer’s server. There is no Developer server for study data.
- Questions, reading texts, listening audio, and transcripts ship inside the app. They are shown and played on device.
- There are no ads, analytics, or tracking SDKs.
- The network is used to (1) read the next test date from jlpt.jp, (2) open public pages such as the exam site or JEES in Safari, and (3) handle App Store purchase or restore (StoreKit). The Developer does not relay that traffic.
- Payment details are handled by Apple. The Developer does not receive card numbers or similar data.
2. Device features
