Effective Date: May 2026
ThreeDays ("the App") is developed by an independent developer. This Privacy Policy explains how we handle information when you use our App.
1. Data Collection
We do not collect, store, or transmit any personal data.
All your tasks, settings, and preferences are stored locally on your device using Apple's SwiftData framework. No data is sent to any server.
2. Data Storage
- On-device only: Your todo items, labels, bundles, and settings are saved in the app's sandboxed storage on your device.
- App and Widget sharing: To display your tasks in the home screen widget, the main app and widget share a local database on your device. All data remains on your device at all times — no network transmission is involved.
- Preferences: We store app preferences locally on your device (notification schedule, date rollover records, purchase status, etc.). This data never leaves your device.
3. In-App Purchases
ThreeDays offers a one-time In-App Purchase ("3Days Pro") processed through Apple's StoreKit framework. During the purchase process, StoreKit communicates with Apple's servers to verify transactions. We do not have access to your payment information. All purchase and transaction data is handled by Apple.
4. Network Communication
The App does not communicate with any developer-owned servers. The only network activity is:
- In-App Purchases: StoreKit communicates with Apple's servers for product loading, purchases, and restoration.
- External links: When you tap on Privacy Policy or Terms of Use links, the corresponding web page opens in your browser.
Your task data is never uploaded through any means.
5. Analytics and Tracking
We do not use any analytics, advertising, or tracking services. The App does not contain any third-party SDKs for analytics or advertising.
6. Notifications and Background Tasks
The App may send local notifications for daily task reminders. These notifications are scheduled locally on your device and do not involve any network communication. You can enable or disable notifications in the App's settings.
The App uses the system's background refresh capability to perform task expiration checks and notification updates locally on your device. No data is transmitted during background execution.
7. Children's Privacy
The App does not knowingly collect any information from children. Since no data is collected from any user, we comply with applicable children's privacy laws.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
