**Effective date:** June 16, 2026

Note Trainer ("this app") respects your privacy and complies with applicable data-protection laws. This policy explains what information the app handles.
## 1. Information this app collects or transmits
### 1-1. Directly identifiable information
This app has no sign-up and does not collect any directly identifiable information such as your name, email, or phone number.
### 1-2. Information stored locally on your device
The following data is stored only on your device and is never sent to any server:
- Quiz records (accuracy, reaction time, session results)
- Weak-note analysis data (notes you miss most)
- App settings (note-naming style, sound on/off, onboarding completion)
Local storage uses `Hive` and `SharedPreferences`.
### 1-3. Information processed by third-party services
**Advertising (Google AdMob)**
This app shows Google AdMob ads. To serve personalized or non-personalized ads, AdMob may collect and use an advertising identifier, IP address, and device information. See Google's Privacy Policy (https://policies.google.com/privacy) for details.
**App Tracking Transparency (iOS)**
On iOS, an App Tracking Transparency consent dialog asks whether to allow tracking. If you decline, the advertising identifier is not used for tracking.
**Google Play / App Store (update & review)**
The app communicates with the store for version checks (in_app_update) and review prompts (in_app_review). This app collects no personal information in that process.

This app requests no sensitive permissions such as camera, microphone, contacts, location, or storage. It uses only internet access for serving ads and checking for updates.
