Privacy policy

Last updated: November 11, 2026

Sprotter has no account and no ads. The only data that may leave your phone is anonymous usage statistics, and only if you agree.

Your location

Your location is used only on your device, to center the map, scan around you and compute walking routes. It is never stored on a server or sent to the developer.

Third-party services

To show places, the app requests map areas (a geographic rectangle, with no identifier) from public OpenStreetMap servers (Overpass). Maps and walking routes are provided by Apple Maps (MapKit), under Apple's privacy policy.

Data on your device

Your targets, favorite places, saved walks and the cache of places (14 days) and routes (30 days) stay on your phone. They are deleted with the app.

Usage statistics

Only if you accept (the app asks once, and you can change your mind in Settings › Privacy), the app sends anonymous usage events to Google Firebase Analytics: features used (scans, walks, favorites, subscription screen), decor types searched and number of places found, planned walks (distance, number of stops and decor types, with or without detours), number of favorites and saved walks, app version, device model, iOS version and country. The position of a scan or of a walk is rounded to about 10 km (the city or district, never the place). Events are tied to a random installation ID, never to your name. No advertising ID, no ads, no sharing for advertising. Data is kept 2 months and may be processed in the United States (EU-US Data Privacy Framework). With the same consent, crash reports (Firebase Crashlytics: the code that failed, device model and iOS version, the last events before the crash) help fix bugs. Turning the option off stops collection and deletes the installation ID. Legal basis: your consent.

Purchases

The Sprotter+ subscription is handled by Apple. The developer never receives your name or payment details, only anonymous sales reports from Apple.

Shared walks

When you share a walk, the link contains its name and its stops (place names and positions, as in OpenStreetMap), never your starting point. The walk is placed after the « # » of the link: browsers never send that part to sprotter.com, so the website does not receive or keep it.

Support emails

If you write to support, we receive what you put in the email, plus the app and iOS versions added to help diagnose issues (you can remove them). Emails are only used to answer you.

This website

sprotter.com uses no cookies and no advertising or cross-site tracking. It is hosted by Cloudflare, which keeps technical logs. To count visits, the site uses Cloudflare Web Analytics: a small script measures, without cookies or any identifier, the page viewed, the referring site, the country, the type of browser and device, and page loading speed. It cannot recognise you from one visit to the next and the data is only shown as totals. Donations are processed by Stripe, under Stripe's privacy policy.
