This policy describes what Amble does with your data. It's written in plain language because that's how privacy policies should be written. If anything here is unclear, email privacy@amble.fit and we'll fix it.
This data is stored on your iPhone in the app's local storage. It does not leave your phone unless one of the following sections applies.
To plot you a route, we send small, anonymous queries to public OpenStreetMap-based services. These services do not know you are an Amble user.
| Service | What we send | Why |
|---|---|---|
| Overpass API (overpass-api.de) | A bounding box around you (typically 1-2 km radius) | To download the walking-path data for your area |
| OpenStreetMap Nominatim | A search string (e.g. "Sheffield Cathedral") or coordinate | When you type into the via-point picker, or to name your start location |
| OpenTopoData / SRTM | A list of route coordinates | To compute the elevation profile of a generated walk |
| open-meteo.com | Your latitude and longitude | To show you the current weather glance |
| BRouter / OpenRouteService / GraphHopper | Route start and end coordinates | When the offline planner can't compute a route and we fall back to a hosted routing service |
These services have their own privacy policies; see Third-party services below. None receive any identifier that links the request to you, your device, or your phone number.
Sign-in is optional. When you sign in, Amble will:
The cloud copy is encrypted in transit (HTTPS) and at rest (Supabase encrypts its disks). You can delete your account at any time from the Profile tab; deleting wipes everything we hold within 30 days.
If you grant permission, Amble can:
This data flows directly between Amble and the iOS Health / Android Health Connect system. It is not transmitted to our servers. You can revoke this permission at any time in your device settings.
If you use the web trip planner, it stores your sign-in session in your browser's local storage so you stay logged in. No cookies are used. Route planning queries are sent to BRouter (an open-source routing service) over HTTPS; these contain route coordinates but no account information.
| Permission | Why | If you decline |
|---|---|---|
| Location (When in use) | To plan a route from where you are, and track your walk | Use Plan-a-Walk mode by typing a start address |
| Location (Always) | To keep tracking your walk when the screen is off | Walk tracking pauses when you lock the phone |
| Notifications | To send a daily walk reminder if you set one | No reminders sent |
| Camera & Photos | To attach photos to walks | Photo feature unavailable |
| Apple Health | To import past walks and save new ones | Health integration unavailable |
Amble does not use any of these. There is no tracking SDK in the app. We don't measure how often you open the app, which features you use, or how long your sessions last. We do not show ads.
Amble is intended for users aged 4 and over. We don't knowingly collect personal information from anyone, of any age, beyond what's described above.
You can:
If you're in the EU/UK, GDPR gives you the right to data access, correction, deletion, portability, and to object to processing. To exercise any of these, email us; we'll respond within 30 days.
Amble uses these external services. Each has its own privacy policy; the terms apply when your device communicates with them.
If we change this policy, we'll update the "Last updated" date at the top and, if the change is material, show you a notice in the app the next time you open it.
