Obviously we have to have a privacy policy.

What data do we collect?

When you visit our site, your browser sends us some data, because that is just how the internet works. We still have to inform you though. This data we recieve when you visit our page (example values for this page in cursive):

• Visited page: /privacy-policy
• Time of access: Nov. 21, 2024, 7:35 a.m.
• From where you were refered to the page
• User-Agent: Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)
• Your IP-Address:

What do we do with the data?

Mostly we don't actually want the data. You just send it to us.

• Visited page: This we need because you expect us to return you a certain page and not just something random (I guess?)
• Time of access: This we don't need, but time is mostly linear, so there is no way of not knowing
• From where you were refered to the page: This we mostly don't need. We use it internally to reduce spamming… If sent from an external page you can complain to the referer, because we can't do anything about it. Links to external pages from this page do not provide a referer.
• User Agent (Used Browser and Operating System): This we neither need nor want. But we also can't do anything about it.
• Used IP-Address: This one we need, firstly because we need to know where to send the response to. Furthermore we use it to automatically deny access to users whose access we suspect to be of malicious nature.

How long do we hold the data?

We delete the logs automatically after 2 weeks
If you're on the blacklist, then you're there for longer. Sorry I guess?
If you want to know what we know about you (although you should know everything since... well you sent it to us) or want us to delete your data, just send us a mail to .
It is probable though that your IP changes daily (then we would require a list of IPs) or you're accessing over DS-Lite (in which case the logged IPv4 represents a block of IPv6, and we can't know which visits were you).
