The ferry takes a PID ticket, like a tram.
This Prague is built from open data. Thanks to:
Made with the open-source libraries three.js, proj4 and Leaflet. Read their licences.
The game has no adverts and no tracking cookies. Your saved games and settings stay in your browser and are never sent anywhere.
The game is sent to you by Cloudflare, which sees your IP address when it does, as any website would. Three other services are asked for something as you play and see your IP address too: Google Fonts for the lettering, Open-Meteo for today's weather in Prague, and a radio station while it plays in a car.
Unless you switch off Anonymous statistics in the settings, the game reports how well it runs for you, which errors come up and what gets played: your browser, system and graphics card, frame rates, which settings get changed, what you do in the game (riding a tram, being arrested, what your money goes on) and how far into a game you first do it, and totals such as time played and distance driven. Nothing in it identifies you: there is no cookie or lasting identifier, your IP address is not kept (only the country it is in), and where you are on the map is not sent. Cloudflare keeps the reports for three months.
If you sign up for news about the game, your email address and the language you picked for the emails are kept by Brevo, the service that sends them, until you unsubscribe with the link in any of them. Cloudflare Turnstile checks that a person is signing up.
Feedback you send reaches the author by email, with your address if you gave one, the game's version, your browser and graphics card, and where you were in the game. It is used only to fix the game and to answer you.
