TL;DR - The Short Version
- No ads. No tracking. No analytics.
- We never sell your data.
- Routes and settings stay on your device.
- Location data is processed on-device for navigation. Mapbox receives map tile requests based on the area you're viewing and waypoint coordinates when using road routing.
- Account info (email) is stored securely via Firebase for authentication only.
PreRun.io is designed with privacy at its core. We collect the minimum data needed to make the app work.
Introduction
PreRun.io ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our mobile application and web app PreRun.io (the "App").
By using PreRun.io, you agree to the collection and use of information in accordance with this policy.
Information We Collect
Account Information
- Email Address: When you create an account (required for Pro features), we store your email address via Firebase Authentication. This is used solely for sign-in and account management.
- Authentication Provider: If you sign in with Google or Apple, we receive your name and email from the provider. We do not access your contacts, calendar, or other account data.
Location Data
- GPS Coordinates: When you use Follow Mode (GPS navigation), the App accesses your device's GPS to show your real-time position on the map, calculate distance to waypoints, and provide turn-by-turn guidance.
- How Location Is Used: Your GPS coordinates are sent to Mapbox to load map tiles and calculate driving routes via the Mapbox Directions API. This is necessary for the app to function.
- We Do Not Store Location: Your GPS position is calculated in real-time on your device. We do not log, record, or store your location history on any server.
GPX Files and Route Data
- GPX Files: When you import GPX files, they are processed entirely on your device. We do not upload or store your GPX files on any server.
- Waypoints and Settings: Your custom waypoint labels, navigation settings, and app preferences are stored locally on your device.
Subscription Data
- Subscription Status: If you subscribe to PreRun Pro, your subscription status (active/inactive and expiry date) is stored in Firebase Firestore linked to your account. This allows the app to verify your subscription across devices.
- Payment Information: Payments are processed by Stripe. We never see, store, or have access to your credit card number or payment details. Stripe handles all payment security.
Information We Do NOT Collect
- Usage Analytics: We do not collect analytics, usage patterns, or track how you use the App.
- Advertising Data: We do not collect data for advertising. The App contains no advertisements.
- Device Identifiers: We do not collect device IDs, IDFA, or fingerprint your device.
- Location History: We do not log or store your GPS position history.
Third-Party Services
PreRun.io integrates with the following third-party services:
Mapbox
- Used for: Map display, 3D terrain visualization, satellite imagery, and driving directions (Directions API)

Firebase (Google)
Stripe

Data Storage
- On Your Device: GPX files, waypoints, navigation settings, cached map tiles, and app preferences are all stored locally on your device.
- In the Cloud (Firebase): Your email address, authentication credentials, and subscription status (active/inactive, expiry date) are stored in Firebase. This data is secured by Google Cloud infrastructure.
- We Do Not Store: Your GPS location, GPX files, route data, or waypoints on any server.
Data Sharing
We do not sell, trade, or share your personal data with third parties for marketing or advertising purposes.
Data is only shared with the third-party services listed above, and only as necessary for the App to function (maps, authentication, payments).
Children's Privacy
PreRun.io does not knowingly collect any information from children under the age of 13. The App is not directed at children under 13.
Data Security
- Local data is protected by your device's built-in encryption
- All network communication uses HTTPS encryption

Your Rights
- Access: Your local data is on your device. Your account data can be viewed in the App's settings.
- Deletion: You can delete your account at any time, which removes all cloud-stored data (email, subscription status). Uninstalling the App removes all local data.
- Portability: You can export your routes as GPX files at any time.
- No Account Required: Free features work without creating an account.
