Checking …
A device key is only needed for the ranking - a random number in your browser, nothing else. No name, no address, no e-mail. You can delete it again at any time.
An account is only needed if you want your progress on a second device. It stores one more thing than the device key: your e-mail address.
Everything you have practiced is stored in this browser. You can take it with you or remove it - it is your data.
Two steps, and you can stop after the first
The device key is a random number that lives in your browser. The server stores only a fingerprint of it, plus a nickname it made up. That is enough to appear on the ranking. There is no name, no address, no e-mail - and if you delete it, nothing of yours remains.
The account adds exactly one thing: your e-mail address. It is only needed if you want your progress on a second device, and later for a subscription. If one device is enough for you, you never need it.
What is stored, and where
- In your browser: everything you practice - character statistics, confusion pairs, settings, speeds. It never leaves the device unless you upload it yourself.
- On the server, with a device key: the fingerprint of the key, your nickname, the country you typed in, and later your results in the daily challenge.
- On the server, with an account: additionally your e-mail address and a hash of your password.
Not stored: your IP address, any location derived from it, your real name, or any tracking of what you look at. There are no cookies on this site at all - the device key travels in a header that only this page sets.
Why the nickname is not free text
Either the site picks a name for you - SWIFT-FOX, CALM-HERON - or you enter a real amateur radio callsign, which is checked against the usual pattern.
The reason is honest and practical: a public list of freely chosen names has to be moderated by somebody, and that somebody would be one person doing it in their spare time. A generated name cannot insult anyone, and among radio operators a callsign is the natural currency anyway.
Frequently asked questions
-
Do I need this to use the site?
No. Translator, decoder, trainers, simulator - everything works without any of this. The only thing you cannot do is appear on a ranking.
-
What happens when I delete the account?
The e-mail address, the password and the nickname are removed immediately and the devices are unlinked. Results already submitted stay in the ranking without a name, because deleting them would move everybody else's position.
-
Can I take my progress to another browser?
Yes, and without an account: "Download my data" gives you a JSON file, "Load data" reads it back in elsewhere. An account only makes that automatic.
-
Why 16 and older?
Under German data protection law, services like this need parental consent below 16. Rather than collect a birth date, the site asks for a confirmation - and keeps everything else usable without an account.
