The short version
We keep what you type into a form on this site, and what signing you in requires. Nothing is sold, nothing is handed to advertisers, and there is no tracker on this site building a picture of you.
What this site keeps about you, why it keeps it, and how to have it removed.

We keep what you type into a form on this site, and what signing you in requires. Nothing is sold, nothing is handed to advertisers, and there is no tracker on this site building a picture of you.
Only what one of the things this site does actually needs:
To answer you, to sign you in, and to run the selection the trainings depend on. None of it is used for advertising, and none of it is passed to anyone who wants to sell you something.
The site runs on services that hold the data on our behalf, and nobody else. They may keep it outside the country:
For as long as it is still doing the job it was given for. Login sessions expire on their own. Ask us to delete your account and what is attached to it, and we will.
Two, and both of them do a job you asked for: one remembers which language you chose, and one keeps you signed in once you have signed in. There is no analytics cookie and no advertising cookie on this site, which is why you have never been shown a consent banner here.
Write to us and ask. You do not need a reason, and asking costs you nothing:
Applying at 17 is normal here. If you are under 18, go through it with a parent or guardian: they are the ones agreeing to it, and they can ask for anything above on your behalf.
The date at the top changes with it. If the change is one that matters, if we start doing something with your details that this page does not already say, we tell the people it affects rather than leaving it to a date nobody checks.
Write through the contact page and say what you want. One of the two founders reads it.
