Privacy

There are no accounts here. We do not collect anything that can identify you. This is the whole list.

The one cookie

When you start a run, we set one cookie. It holds a random run number and a signature. It lasts a year. It is there so you can continue a run and reach your results afterwards. It holds nothing else. We do not use it to track you, to advertise, or to link your runs together.

What we store about a run

• For each game: the door you picked first, the door that opened, whether you stayed or switched, where the car was, and the time you decided.
• For the run: how many games you played, your running counts, and whether you finished.

What we do not store

• No name, email address, or any other personal detail.
• No IP address, browser, device, or location in our own database.
• No analytics, no tracking pixels, no third-party scripts, no fingerprinting.

The web server in front of this app may keep short request logs that include IP addresses, as almost every web server does. Those logs are for running the site. We never join them to run data.

Adverts

These pages keep space for adverts. If an advert is served by another company, that company sets its own rules about what it collects. We do not share anything from your run with it.

Linking runs

We do not link runs to each other or to a person. If you play several times, each run is separate. From the stored data, there is no way to tell that two runs came from the same visitor.

Published numbers

The totals on Everyone are built from run counts. No single run is named there.
