Our own example page
These are two imagined games, with no download and no account. Each button opens only a short text on this page.
Explore a puzzle
A door with three symbols. A note with a clue. You try different orders until the lock clicks. That could be the start of a small puzzle game.
Build a world
An empty island is waiting for your ideas. Add paths, build a lookout and connect two riverbanks. There is no right result, just your design.

After 30 seconds without clicking, typing or scrolling, timing pauses. No typed content or pointer paths are saved. Sleep, slow devices and privacy protections can leave time uncounted.

That is not a cookie and is not automatically sent with server requests. “Delete experiment data” removes only this experiment.Storage and limitsGamesSportTravelWhat do your clicks reveal?Open a topic. Then see what the demo observes — and what it can only guess.One click. One trace. Many possible reasons.Try it with my own clicksView an example without savingStart a new round with my clicksWith your own clicks: Only after you start do we save your topic choices in this browser tab. No experiment data is sent, and no real name is used. We do not measure reading time here. Example mode saves no new experiment data. On the optional example pages, we then also count page visits, button clicks and active-window time — not measured attention.Valid for up to 30 minutes; expired data is removed at the next check. You can delete it yourself at any time.View saved topicsThis tab still contains experiment data. A new round replaces it. Example mode leaves it unchanged.Your clicks · in this tabExample · no new saved dataStartFinishStep {step} of 4BackOpen a topic that makes you curious right now.OpenTopic opened: {topic}.Possible interest: {topic}.Does the demo now know for sure that you are interested in {topic}?YesNoNot sureThat would read too much into it.Exactly: the click does not reveal your reason.That uncertainty makes sense.Perhaps you were curious. Perhaps you were just following the instructions. The demo does not know your reason.A website can save something in the browser and read it again later. That recognizes stored data first, not a person.A note in the browserTopics in this tabFictional identifierNot checked yetFind the saved topics againShow recognition in the exampleReload and check againFound in this tab: {topics}. We read the saved experiment to find this. It does not tell us your name.Found again after reloading: {topics}. The note is still there — we have not identified a person.In the example, A7 is read again. The same identifier does not necessarily mean the same person. A7 is only an illustration here and is not saved.Your actual experiment data is in this website’s tab storage (sessionStorage). Reloading does not remove it. Browsers, profiles and other websites do not simply share this storage.Cookies and tab storage: what is the difference?Now an illustrated story: the fictional person Hugo Müller signs in with the same provider. What could the provider connect?Simulate signing in as HugoIn the example, the provider links identifier A7 to Hugo’s account. Hugo supplied the name himself when signing in.A7 and Hugo Müller are fictional. We have neither discovered nor asked for your name. This login does not automatically reveal the name to other websites.Technology helps. Your behavior matters too.Tor protects the connection route.A regular website sees the Tor exit’s IP instead of your connection’s IP. This does not make an account or information you provide disappear.Consider what you share.Where you sign in and what you provide also matter. Tor Browser limits further recognition, but does not prevent every form of tracking.You open a sports article to find a gift. Which statement is an observation?The sports article was opened.You are a sports fan.Exactly. “Opened” is observed. “Sports fan” would be an uncertain interpretation.That would be a guess. The only observation was that the article was opened.Choose another topicChoosing another topic does not delete existing experiment data.
