Privacy Policy
The short version: Spur collects no data. It has no accounts, no analytics, no advertising, and no servers of its own. Your activity files stay on your Mac. The only network traffic is the map imagery the app downloads to draw the map under your route.
What Spur does with your files
Spur is a viewer. It opens GPX, FIT, and TCX files you choose and reads them in place. It never uploads, copies, or transmits them. When you export an image, a GPX conversion, or a print, the result goes only where you send it: the file you save, the clipboard, the share destination you pick, or your printer.
Two small things are stored locally so the app works better next time:
- Estimated elevation. For files without elevation data, Spur derives a profile from terrain tiles and caches it alongside the file as an extended attribute (and in the app's own container when the file can't be written). This is derived data about the route, not about you, and it is removed with the file.
- Preferences. Your unit system, map style, and layout choices are kept in the app's preferences on your Mac, shared only with Spur's Quick Look extensions so previews match the app.
Network access
When your Mac is online, Spur downloads map imagery from the following services to render the map around your route. These requests work like any web map: the service receives your IP address and the coordinates of the map tiles being drawn, which correspond to the area you are looking at. Spur sends nothing else — no file contents, no identifiers, no route geometry.
| Service | Used for | Operated by |
|---|---|---|
| OpenFreeMap | Vector map tiles and fonts for the Topo and Night styles | openfreemap.org |
| AWS Terrain Tiles | Elevation data for hillshading and estimated elevation profiles | registry.opendata.aws |
| Esri World Imagery | Satellite imagery, only when the Satellite style is selected | esri.com |
Each service has its own privacy practices, linked above. Downloaded tiles are cached on your Mac so repeated views don't fetch them again.
If you prefer that no map requests leave your Mac, use Spur offline. The complete offline world map that ships inside the app renders your route with no connection at all, and the Quick Look thumbnails and previews in Finder always work offline and never connect to anything.
What Spur does not do
- No analytics, telemetry, or crash reporting of its own. If you have enabled sharing of diagnostics with developers in macOS System Settings, Apple may share anonymized crash reports with us under Apple's privacy policy.
- No accounts, sign-in, or cloud sync.
- No advertising and no third-party tracking SDKs.
- No access to your location, contacts, calendar, camera, microphone, or health data. Spur never asks for these permissions.
Purchases
Spur is sold through the Mac App Store. Apple processes the purchase and handles receipts; we receive no personal information about buyers.
Children
Spur does not collect personal information from anyone, including children.
Changes
If this policy changes, the new version will be posted here with a new effective date. Because Spur collects no data, changes would only describe new features, never new collection without a clear notice.
