Privacy and external services in Distance Master
Distance Master sends only the customer’s postcode to Nominatim, and the shop and customer coordinates to OSRM. It sends no names, emails, addresses or order data. Results are cached locally for 30 days.
External services
| Service | Receives | Policies |
|---|---|---|
| Nominatim (OpenStreetMap) | The customer’s postcode only | Nominatim usage policy, OSM privacy policy, OSM terms of use |
| OSRM (router.project-osrm.org) | The shop coordinates and the customer’s resolved coordinates | Project OSRM, OSRM backend |
Caching
Postcode-to-distance results are cached for 30 days in WordPress transients, so a repeat postcode makes no external request. The cache index is capped at 2,000 keys.
Data and uninstall
Deactivating never deletes data. Tick Delete plugin data on uninstall (off by default) to remove settings when you uninstall.
Security
Checkout validation uses WordPress nonces, and inputs are sanitised.
Public servers
The public Nominatim and OSRM servers have fair-use policies. Busy stores should consider hosting their own OSRM instance. In this version the OSRM address is fixed to the public server.
