Nothing. Here is how to check that yourself.
This whole test is about not taking a company’s word for it, so our word for it should not be worth much either. What follows is not a promise. It is your own browser, reporting what this page has actually done while you have been reading it.
Your browser's own answer, right now
Your browser keeps its own record of every site a page contacts and everything a page saves on your machine. This reads that record back to you. Nothing below left your computer.
Checking…
What that means
There is no account, no email box, no cookie, and nothing counting what you read or how long you stayed. The test itself lives in this browser tab and is gone when you close it. If you send someone your result, your answers ride inside the link itself, in the part after the # that browsers keep to themselves and never pass on — so even then, no computer of ours ever sees them. The single exception is described below, and only happens if you choose it.
And it cannot quietly stop being true. If a future version of this page ever loaded something from another company, set a cookie, or wrote anything to your browser, it would fail its own checks and never reach you.
The one exception, stated plainly
There is a part of this test where you can ask a question of your own. That part cannot work without sending something somewhere, and it would be dishonest to bury that on a page called “what we store”.
If — and only if — you choose to use it, what you selected and what you type are sent to our own server in Germany, which asks an AI service running in France. Neither of them writes any of it down. We still never ask who you are, so there is no name to attach to it. You are told this on the screen before you use it, not afterwards.
While it answers, that same server also goes and reads your suppliers’ own pages again, so you get what they are saying today rather than what we wrote down weeks ago. Our server does that, not your browser, and it tells the supplier nothing about you: not your question, not your name, not where you are. It is only allowed to open pages this test already lists, so nothing you type can send it off somewhere else. Every answer shows you which pages it read, and at what time.
At the very end there is a second one, and it only happens if you fill it in: the test offers to introduce you to us. You are shown the exact lines that would be sent before there is a button to press, you can leave them out, and your address is used to reply to you and for nothing else. It is not added to any list. That mail is the only record of it — nothing about it is written down at this end either.
Every other page here, including the whole test, sends nothing. The check above will show you that: use the test, then come back and look again.
Why it is built this way
We are telling you that your tools quietly hand your work to companies you never chose. If this page did the same thing, the first person to check would have every reason to stop listening — and they would be right.
