01 Privacy Philosophy
At FastPure, we believe tracking your intermittent fasting routine should remain 100% private and air-gapped. FastPure is designed as a standalone, lightweight utility app. We do not operate remote servers, track user behavior across apps, or collect any personal information.
02 Data Inventory Matrix
The table below summarizes how FastPure handles data on your device:
| Data Type | Collected Remotely? | Stored Locally? | Notes |
|---|---|---|---|
| Personal Identifiers | NO | NO | No account, email, or registration required. |
| Fasting Logs & History | NO | LOCAL ONLY | Stored in local sandbox preferences on your hardware. |
| Location & IP Address | NO | NO | No GPS, IP, or network location tracking. |
| Analytics & Advertising | NO | NO | Zero third-party trackers, analytics, or ad SDKs. |
| Payment Details | NO | NO | Processed 100% securely by Apple & Google. |
03 System Permissions
FastPure requests only essential system permissions required for local features:
| Permission | Purpose | Network Access |
|---|---|---|
| Local Notifications | To alert you locally when your fasting goal is reached or when metabolic milestones (Ketosis, Autophagy) occur. | NONE (100% Offline) |
| Widgets & Shared Memory | To display live countdowns on home screen widgets (iOS WidgetKit / Android Glance) and Live Activities. | NONE (On-Device App Group) |
| Local Storage & File Sharing | To persist preferences and generate manual CSV history exports on your device. | NONE (Offline Sandbox) |
04 On-Device Storage & Sovereignty
All fasting logs, protocol selections (14:10, 16:8, 18:6, 20:4, OMAD 23:1, Custom), streaks, and user settings are stored exclusively in local storage on your device hardware.
- Your data remains inside your operating system's application sandbox.
- We operate no cloud database, so we cannot access, view, sell, or analyze your data.
- Data is never transmitted to any remote servers.
05 In-App Purchases
FastPure is free to use with the 16:8 protocol, with a one-time lifetime purchase (FastPure Pro) to unlock all other protocols, full history & stats, CSV export, and metabolic milestone notifications. The end-of-fast alert stays free for everyone.
FastPure Pro is a single, lifetime unlock. There are no recurring subscription fees. Payments are handled directly by the Apple App Store or Google Play Store under their official store privacy policies.
06 Local Notifications
The end-of-fast reminder (free for everyone) and the metabolic milestone alerts (Ketosis, Autophagy — a FastPure Pro feature) are scheduled natively on your operating system's local notification engine. No push servers are used.
07 Data Control & Total Deletion
- CSV Export: With FastPure Pro, you can export your complete fasting history log as a raw CSV file from the History tab at any time.
- Total Deletion: Uninstalling FastPure permanently deletes all locally stored data and preferences from your device hardware.
08 Health & Educational Disclaimer
FastPure is a time-tracking tool for informational and educational purposes only (tracking metabolic stages such as digestion, fat burning, and autophagy). It does not provide medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before beginning any fasting routine.
