HAIRPIN

Privacy policy

Privacy

Hairpin is built for driving, not for collecting data. This page lists everything that leaves your phone, where it goes and why, in plain words.

Last updated: 27 September 2026

What we don’t do

Who is responsible

The data controller is Simone Spinozzi, a private individual who develops Hairpin. For anything about your data, write to privacy@hairpin.racing. For help with the app: supporto@hairpin.racing.

There is no data protection officer: the law does not require one for a project like this.

What leaves your phone, and where it goes

To find the roads and draw the map, Hairpin has to ask a few other services. Every request carries your IP address, like any internet connection. Here they are, one by one.

Your phone does the rest, under its own rules: the position is worked out by the system (Apple or Google), the voice is the system’s own, and if you download the app from a store, Apple or Google handle the download under their policies. For these, Apple and Google are controllers in their own right, not us.

Each of these services is itself bound by the GDPR, by a law the EU recognises as equivalent (United Kingdom, Switzerland) or, for Cloudflare in the USA, by the EU–US Data Privacy Framework: they give your data the same protection, and you the same rights, described on this page. What each one keeps, and for how long, is written in its card.

What stays on your phone

Recorded drives, your corrections to the notes, recent routes, roads saved for when there is no signal, and your settings stay in the phone’s storage. They are also in the backups your phone makes to your Apple or Google account: those are your copies, not ours.

They leave the phone only if you export a drive or share a route. To delete them, delete them in the app, or uninstall it.

No cookies. The site remembers the language you pick, and the web app your settings, in the browser’s own storage, on your device only, because they need them to work.

A route link carries the start, the stops and the finish, with their names and their coordinates to about a metre: if the start is “Your location”, the link says where you are. It goes wherever you send it. The part after the # never reaches our server.

How long

We keep nothing that says who you are, apart from the emails you send us, only for as long as it takes to handle the request. Otherwise we keep only the road data of an area, for up to 7 days, without your IP. What the other services keep is written in their cards above.

How your data is protected

Every connection the site and the apps make travels encrypted (HTTPS), including the one from Cloudflare to the road servers; the versions we publish don’t allow unencrypted connections. What stays on your phone sits in the storage reserved to the app (for the web app, to the site, in your browser). We don’t switch on Cloudflare’s visit logs, our road server’s log records only Cloudflare’s address, and Cloudflare handles the data only on our behalf, under a data processing agreement.

Outside the European Union

Three recipients are outside the EU. Cloudflare (USA): the transfer relies on an EU adequacy decision, the EU–US Data Privacy Framework (art. 45 GDPR, decision 2023/1795), to which Cloudflare is certified; if its certification lapses, the Commission’s standard contractual clauses already in its data processing agreement (section 6) apply. The OpenStreetMap Foundation (United Kingdom), covered by an EU adequacy decision, whose map network can serve you from anywhere in the world. Proton (Switzerland), covered by an adequacy decision. komoot, our road server and the public Overpass servers are in the EU.

Your rights

You can ask to see your data, correct it, delete it, limit its use or take it with you (articles 15 to 20 of the GDPR). Write to privacy@hairpin.racing: we answer within a month. Unless you have written to us, we keep nothing linked to you, so we will often have nothing to show; if so, we will tell you. For what Nominatim, the map, Photon and the public Overpass servers receive, you can also write to them directly.

Right to object. Everything described in the cards above is based on legitimate interest, so you can object to it at any time, on grounds relating to your particular situation (art. 21 GDPR): write to privacy@hairpin.racing or, for what they receive, directly to Nominatim, the map, Photon and the public Overpass servers. One limit: the services your phone contacts directly cannot answer without receiving your IP address, and on the road requests to the Overpass servers Cloudflare passes your IP address along in a header that cannot be removed; so for that part objecting means not using the service.

You can complain to the Italian data protection authority, the Garante per la protezione dei dati personali, or to the authority of the country where you live.

You don’t have to give us anything. Your position is what lets the app follow the road while you drive; without it you can still type places and read the notes. No automated decisions are made about you.

Children

Hairpin is made for people who drive. We don’t ask anyone’s age and we don’t build profiles of anyone.

Changes

If something changes, we write it here and update the date at the top. If a new feature sends something new off your phone, the app asks you before it does.
