- Effective date: July 6, 2026
- Last updated: July 6, 2026
This policy explains how the mobile application **D-day Counter+** ("this app") handles user data. This app requires no account or sign-up and does not collect personally identifiable information.
## 1. Data We Collect or Transmit
### 1-1. Personally identifiable information
This app does **not** collect names, email addresses, phone numbers, accounts, or any other directly identifying information. There is no sign-up or login feature.
### 1-2. Data stored locally on your device
The following data is stored only on your device and is never sent to any server:
- D-day entries you create (title, target date, start date, emoji, memo, category)
- App settings (theme, language, onboarding status)
Storage: a local database (Hive) and app preferences (shared_preferences). To display the home screen widget, part of this data may be copied to the device's widget storage area, which also remains on the device only.
### 1-3. Third-party service — Google AdMob (advertising)
This app uses Google AdMob to serve ads. AdMob may automatically collect:
- Advertising identifier (Advertising ID / IDFA)
- IP address and approximate location (IP-based)
- Device information (model, OS version, screen size, etc.)
- Ad interaction data (impressions, clicks)
See: [Google Privacy Policy](https://policies.google.com/privacy), [Google Advertising Policies](https://policies.google.com/technologies/ads)
On iOS, tracking permission is controlled by you through Apple's App Tracking Transparency (ATT) prompt. In regulated regions (e.g., the EEA), a Google UMP consent form is shown.
### 1-4. App update check
This app uses Google Play's in-app update feature to check whether a new version is available. No personal data is collected in this process.

This app does **not** request sensitive permissions such as camera, microphone, contacts, location, or storage. It only uses internet access for loading ads and checking updates.
## 3. Data Retention
