Trafica, website and iPhone app

Trafica shows trains, roads and prices from public sources. It needs nothing about you to do that: no account, no cookies, no analytics, no ads and no tracking. What it does receive, and what it keeps, is below.

Who decides

MAXOPOLI, a sole proprietorship in Ontario, Canada, runs Trafica and decides how anything you send is used. The owner's name, and how to write to him, are on the contact page.

Every visit

Vercel hosts this website and its servers. Vercel's request logs record each request (its time, the address asked, your network address and your browser) for Vercel's own log period. Vercel is in the United States and certified under the EU-US Data Privacy Framework, which the European Commission found adequate on 10 July 2023. Every page, font, map and video comes from this site, so no other company sees your visit. The world clock keeps the cities you pick in your own browser and sends them nowhere.

Your position

Only when you tap the map's location button, or Find me, and allow it. Your phone's exact point stays in the page. To find the trains around you, the page sends Trafica that point rounded to about 100 m, inside the request's body, so no request log holds it. While you move, your course goes with it, rounded to a whole degree, so trains going the other way are left out. Trafica answers with the trains near it and keeps none of it. If you turn on the ride log in that card, each answer, and your fix every 5 seconds, is kept in your own browser, with your exact point, for 7 days or until you delete it, at most 4,000 entries; it leaves the phone only if you copy it. The same answer can also be asked with the point in the web address (GET /api/italy/near), which Cove's page uses; asked that way, the address, with the point in it, can land in a request log, and the answer is cached for 20 seconds. This site and the iPhone app ask the body way only.

The two forms

“Tell me when it's ready” keeps your email. “Submit your own walk” keeps your email and what you write: the place, the camera, a link and your notes. Both are kept in a private store at Vercel, only to write to you about that, until you ask for them to be deleted. Max alone reads them, and nothing goes to marketing. You give them by consent (GDPR art. 6(1)(a)) and may withdraw it at any time.

The contact form

Your message goes to Max by email, through Brevo, and no copy stays on this website. The contact page says how it is handled.

The iPhone app

No account, no analytics, no ads and no tracking. The train you follow and the stop you choose stay on the phone.

Your position, only after you allow it: while the app is open, and, if you turn on the always-on pin, in the background while you follow a train, until it arrives or you stop following it. The exact point stays on the phone. Trafica gets it rounded to about 100 m, in the body of a request, to find the trains around you, and keeps none of it.

Alerts with the app closed: the phone's push address (a token Apple gives the app), the train you follow and the phone's language go to Trafica's watcher. They are kept in a private store at Vercel until the train arrives, you change train, or 36 hours pass, whichever comes first. The alert travels through Expo's push service and Apple's. Change train, and the watcher lets go at once.

Your rights

You may ask to see what is kept about you, to correct or delete it, to limit or object to its use, and for a copy, through the contact page. You may also complain to the Garante per la protezione dei dati personali (garanteprivacy.it), or to the authority where you live. No decision about you is made by machine.
