Privacy Policy
자린이와 고비들 ("the developer") values the privacy of users of the iOS/iPadOS application Zarinegobi (자린이와 고비) ("the app") and complies with applicable laws. This policy transparently describes how information is handled while you use the app.
The app does not directly collect or store personally identifiable information such as your name, phone number, or address. The ledger data you enter is stored only in your own Apple iCloud account and is inaccessible to the developer.
1. Information processed
The app processes only the limited information listed below. The developer does not collect or store any data on its own servers; the items below are processed through third-party services (Google, Apple).
| Actor | Items | Nature |
|---|---|---|
| App (local) | Income, spend, memos, categories, goals you enter | Your device and your iCloud only |
| iCloud (Apple) | Cloud copy of the local data above | Managed by Apple; inaccessible to the developer |
| Firebase Analytics (Google) | Anonymous app events, device model/OS/language, app version, coarse region | Aggregate stats for quality improvement |
| Google AdMob | Advertising identifier (IDFA etc.), IP address, ad impressions/clicks | Ad delivery and measurement |
1-1. Information collected directly by the developer
None. There is no sign-up process, and no user data is stored on servers operated by the developer.
2. Purposes of use
- Ledger functionality: save and sync the data you enter across your device and iCloud.
- Quality improvement: detect crashes and improve features using anonymous Firebase Analytics statistics.
- Ad delivery: show in-app ads via Google AdMob and control ad frequency via advertising identifiers.
3. Retention period
- In-app ledger data: retained on your device/iCloud until you delete it or uninstall the app.
- iCloud data: retained according to Apple's iCloud policy; you may delete it in Apple Settings.
- Firebase Analytics data: retained per Google's default retention (up to 14 months).
- AdMob data: retained per Google's policies; you may reset the advertising identifier or limit tracking in device settings.
4. Third-party providers and processors
The developer does not provide or sell user information to third parties without your consent. The following services are used to operate the app and deliver analytics/advertising.
- Apple Inc. (iCloud / CloudKit) — cross-device sync · Apple Privacy Policy
- Google LLC (Firebase Analytics) — anonymous usage statistics · Firebase Privacy and Security
- Google LLC (Google AdMob) — advertising · Google Ads policies
5. Cookies and similar technologies (advertising identifiers)
Web cookies are not used. However, Google AdMob uses advertising identifiers (e.g., IDFA) and IP addresses for personalized advertising and frequency capping. On iOS 14+, when asked, you may choose "Ask App Not to Track" under App Tracking Transparency, or reset the advertising identifier under "Settings → Privacy & Security → Apple Advertising."
6. Your rights
- Access / correction / deletion: You may view, edit, or delete in-app data at any time. iCloud data is managed via Apple Settings.
- Opt-out: You may limit ads/analytics through your device settings or by uninstalling the app.
- Inquiries: Please contact the privacy officer below to exercise your rights.
7. Data security
The app does not transmit your data to servers operated by the developer. iCloud sync uses Apple's encrypted CloudKit infrastructure. Communication with third-party services (Firebase, AdMob) is encrypted via TLS.
8. Children's privacy
The app is not intended for children under the age of 13, and the developer does not knowingly collect personal information from children under 13. If we become aware that personal information from a child under 13 has been collected without proper consent, we will delete it promptly.
