Privacy Policy

FastFaster ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application FastFaster: Intermittent Fasting (the "App").

Please read this Privacy Policy carefully. If you do not agree with the terms of this Privacy Policy, please do not download or use the App.

1. Information We Collect

FastFaster is designed to protect your data. We operate under a privacy-first, local-first architecture with private iCloud synchronization. The App does not require user accounts, email registration, or passwords to function.

A. HealthKit Data (Apple Health Integration)

The App requests read and write access to Apple's HealthKit database (HKHealthStore) to provide weight and workout tracking features.

  • Data Requested: Weight (Body Mass), blood oxygen, active energy burned (calories), distance (cycling/walking/running/swimming), cardio fitness (VO2 max), and workout activity types.

  • Storage: All HealthKit data is read from and written directly to your device's Apple Health App database. We do not store, upload, or transmit this data to any external servers.

  • HealthKit Restrictions: In compliance with Apple developer policies, we do not use HealthKit data for marketing, advertising, or profiling, nor do we sell, rent, or disclose your HealthKit data to any third parties.

B. Local App Storage & iCloud Sync (SwiftData & CloudKit)

  • Your fasting sessions, manually logged weights, workout logs, and customized goals are saved locally on your device using Apple's secure SwiftData framework.

  • iCloud Sync: If you are signed in to your Apple ID and have iCloud enabled, your data is synchronized across your devices using Apple's secure CloudKit database. This synchronization occurs directly and securely between your devices and your personal, private iCloud container (iCloud.com.anasdamri.fastFaster).

  • Access: We do not host, store, or have any access to your data or your iCloud container. The transmission and storage of synced data are fully managed by Apple's secure iCloud infrastructure, and we do not have access to your iCloud account or backups.

C. Technical Data & Logs

  • The App runs entirely on-device and does not send telemetry, analytics, crash logs, or usage metrics to us or any third-party analytics SDKs.

2. How We Use Your Information

We do not have access to your information. The data processed on your device is used solely to:

  1. Calculate and display fasting timer durations and biological phases.

  2. Visualize weight loss trends and goal progression via interactive charts.

  3. Calculate active calories burned and exercise minutes for daily activity rings.

  4. Trigger local notifications reminding you of fasting milestones (e.g., entering Ketosis or completing a fast).

  5. Generate Dynamic Island and Lock Screen Live Activities.

3. Sharing and Disclosure of Information

We do not sell, trade, license, or rent your personal health data to anyone.

Because we do not collect or store your data on our own external servers, we cannot disclose it to third parties. Your data remains under your absolute control on your physical devices and in your private iCloud storage.

4. Security of Your Data

We rely on Apple's robust security architecture (iOS Sandbox, File Data Protection, Apple Health encryption, and iCloud/CloudKit security) to safeguard your data. HealthKit data is encrypted on-device when your phone is locked with a passcode/FaceID, and any data synchronized via iCloud is stored securely in your private Apple iCloud container, encrypted both in transit and at rest.

5. Your Choices and Data Management

You have complete control over your data:

  • HealthKit Permissions: You can grant, modify, or revoke FastFaster's access to read or write weight and workout data at any time by opening the native Apple Health App > Profile (top right) > Apps > FastFaster.

  • Notification Controls: You can enable or disable fasting milestone alerts in Settings > Notifications > FastFaster.

  • Live Activities: You can disable Lock Screen and Dynamic Island widgets in Settings > FastFaster > Live Activities.

  • iCloud Sync Controls: You can disable iCloud synchronization for FastFaster at any time by going to your device's Settings > [Your Name] > iCloud > Apps Using iCloud (or Saved to iCloud) and toggling FastFaster off.

  • Data Deletion: To permanently delete all fasting sessions, weight entries, and goals recorded in the App, you can uninstall the App from your device. If iCloud sync is enabled, uninstalling the app or deleting its container data through Apple's iCloud storage settings will also clean up stored data in your private iCloud database. To delete HealthKit records, you must delete them from the native Apple Health App.

6. Children's Privacy (COPPA Compliance)

Our App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. Since we do not collect any user registration data, children's privacy is protected on-device and within their private iCloud account.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by updating the "Effective Date" at the top of this document and displaying a notice in the App Store update notes. You are advised to review this Privacy Policy periodically for any changes.
