Privacy Policy
This Privacy Policy explains how Quick Vocabnote (the "App") handles personal information.
1. Information We May Collect
The App may collect the following information. None of this information is linked to personally identifiable information such as your name, email address, or phone number.
Purchase Information
To manage the status of premium features (a one-time, non-consumable in-app purchase), the App retrieves your in-app purchase history through Apple StoreKit. This is processed via Apple's StoreKit framework and RevenueCat (a third-party service), and is used solely to verify your purchase status.
Advertising Information
For ad delivery and optimization, the following information may be collected through Google AdMob (a third-party service):
- Device identifier (IDFA) — only if you grant permission via ATT
- Coarse location (country / region level)
- Product interaction data within the App
- Advertising data (ad impressions, clicks, etc.)
Diagnostics
To improve App stability and performance, the App may collect standard diagnostic data provided by Apple:
- Crash data
- Performance data
- Other diagnostic data
2. Purposes of Use
The collected information is used solely for the following purposes:
- Enabling and verifying premium features
- Restoring past premium purchases (Restore Purchases)
- Ad delivery and optimization (Google AdMob)
- Fraud detection and ad performance measurement
- Improving App stability and performance
3. Third-Party Services

4. Tracking and External Transmission
The App may track certain data (IDFA, interaction data, coarse location, etc.) through Google AdMob to optimize ad delivery.
About App Tracking Transparency (ATT)
On iOS 14.5 and later, a tracking permission dialog will appear at first launch. If you select "Ask App Not to Track", the IDFA will not be collected and only non-personalized ads will be shown.
Disabling Tracking
You can change the tracking permission for this App at any time from iOS Settings → Privacy & Security → Tracking.
Note that the auto-translation and text-to-speech features operate entirely on-device and do not transmit any data to external servers.
5. Data Storage
User-created vocabulary and deck data are stored in the following locations:
- A local database (SQLite) on the device
- If the user is signed in to iCloud, the user's own private iCloud database (CloudKit)
The developer has no access to any of this data.
6. Children's Privacy
The App is not intended for children under the age of 13, and we do not knowingly collect personal information from children under 13.
7. Changes to This Privacy Policy
This policy may be changed without prior notice. The updated policy will be posted on this page.
