Privacy policy

Navigation pages (/q, /map): your language choice (a cookie) and, only if you allow it, your device location — used on your device and for routing. While you navigate we also keep an anonymous trace of the walk (positions under a random id, never linked to you) to improve the map and directions. Standard analytics (Google Analytics) measure page visits.

Mapper app: your account (name and email from Sign in with Apple or Google) and the walks you record — 3D geometry of streets and GPS trajectories. The camera is used only for motion tracking on your device; no photos or video are ever saved or uploaded.

Only if you agree. The iPhone and Android apps ask once, before anything is collected, and you can change your answer any time in Profile. If you say no, nothing is sent — that is also the default on a fresh install.

If you say yes, we use Google Analytics for Firebase and Firebase Crashlytics (Google Ireland Limited) to count which screens and features get used, and to receive crash reports so we can fix them. What is sent: the screen or button name, counts, your language, the app version, a random app-instance identifier, device model and OS version, and your approximate country, which Google derives from your IP address and which we cannot switch off. What is never sent: your name, your email, your account, your saved accommodation, your search text, or your GPS position. Advertising identifiers are disabled outright (no IDFA, no Android advertising ID, no IDFV, no SSAID); nothing is used for advertising or shared with advertisers.

Legal basis: your consent (ePrivacy Article 5(3); GDPR Article 6(1)(a)). Withdraw it any time in Profile — the analytics identifier is then deleted from your device and collection stops. Retention: events 14 months, crash reports 90 days.

The anonymous walk trace described above is separate and continues regardless of this setting: it carries no identifier of any kind, never leaves our own servers, and exists so we can find where our directions send people wrong.

Walk data builds the public street map of the island. Approved contributions earn points shown on the public leaderboard (first name only). We don't sell personal data.
