RailPin is a preview service operated by Exametry.xyz (“we”, “us”, “our”). We are the data controller responsible for the personal data described in this notice.

RailPin is an evolving prototype. This notice describes how the current version handles data and may be updated as the service develops.
To make the app work, we save a small amount of information in your browser’s local storage. This is not a cookie, is never transmitted to us, and stays on your device until you clear it:
rp_home | The “Home” location you set (a map coordinate), so the map can orient to it on return. |
|---|---|
rp_consent | A flag remembering that you’ve seen this notice, so it isn’t shown on every visit. |
Lawful basis: strictly necessary for a service you have requested. You can remove this at any time by clearing “Home” in the app or clearing your browser storage.
If you use the “locate me” or GPS features, your browser will ask your permission to share your location. If you allow it, your coordinates are used in the app to place you on the map and are sent to our service only to look up the nearest railway track and place name. We do not store your location or link it to your identity.
Lawful basis: your consent (the browser permission prompt). You can decline, or revoke it later in your browser/device settings, and still use the rest of the app.
If you choose to add a new structure or submit a correction, we receive and store the information you provide — for example the structure’s position, type, reference codes, mileage and any free-text notes you type — together with technical metadata (a timestamp and your IP address, used to prevent abuse). We store this so we can review, moderate and, where appropriate, publish it.
Please do not include personal information about yourself or others in free-text notes. Lawful basis: our legitimate interest in building and verifying an accurate railway dataset, and your voluntary submission.
Like any website, our servers and content network automatically record basic technical information (IP address, browser type, and the requests made) in short-lived logs to keep the service secure and working. Lawful basis: our legitimate interest in security and reliability.
We do not use any cookies of our own, and we do not use analytics or advertising. The only first-party storage we use is the essential browser storage described in section 2(a).
However, RailPin embeds third-party services that may set their own cookies or storage and receive your IP address when their content loads:
Because we only use essential storage and no tracking, we show a one-time notice rather than a consent wall. You can withdraw from third-party content at any time by not using the map, or by blocking those domains in your browser.
We do not sell your data or use it for advertising. Data is processed by the providers above (Google, Cloudflare, jsDelivr, unpkg) solely to deliver RailPin. Some of these providers may process data outside the UK and EEA; where they do, they rely on appropriate safeguards such as the UK Addendum to the EU Standard Contractual Clauses. We may also disclose information where required by law.
Under UK data protection law you have the right to access, correct, erase, restrict or object to our processing of your personal data, and to data portability. To exercise any of these, email [email protected]. You also have the right to complain to the UK Information Commissioner’s Office (ico.org.uk) if you are unhappy with how we have handled your data.
RailPin is not directed at children and we do not knowingly collect data from children.
We may update this notice as RailPin develops. The “last updated” date above shows the current version.
