Thoughts on Computer Science, Politics and Philosophy



I’m not interested in your data and I don’t save any of it that’s not needed for my websites to work. If you have any questions about your data, do not hesitate to contact me.

The annoying part

Now, thanks to the European General Data Protection Regulation (GDPR) I have to provide this superfluous privacy statement. It caused me serious pain while writing (I hate beaurocracy) and nobody will ever read it. By the way, meanwhile Facebook, Microsoft, Google & Friends are still unethically collecting everybody’s data in bulk pretty much undisturbed. Oh, and a lot of small sites had to close due to this beaurocracy, pushing their users to said corporations. Anyway – enjoy!

This privacy statement is applicable to the following public web services I provide:

Your Data


All my services are only available using modern and state-of-the-art end-to-end encryption using TLS and HTTPS, meaning that nobody, like providers and attackers, should be able to read the contents of any communications between my services and you.

However, please keep in mind that even state-of-the-art technology can have security holes. Therefore, a gapless protection of all data cannot be guaranteed.


My websites https://online-lenz.de, https://eisfunke.com and https://assets.eisfunke.com are hosted on a virtual server provided by Netcup GmbH.

As that server is not under my direct control, please consult the absolutely beautiful and not at all beaurocratic and superfluous additional agreement concerning the mandated processing of data (in German).

All my other services are served from my homeserver completely under my control. The internet connection is provided by Telekom Deutschland GmbH. As mentioned, all my services are only available over encrypted connections, so they should only be able to collect meta information like the times of visits to my sites, something your own internet service provider is capable of anyway though.


My servers do not keep any access logs. That means that under normal cicrumstances I do not know when somebody used my websites. I do however keep error logs for diagnostic purposes which contain the IP address of the client that caused the error. These logs are deleted regularly.

I don’t use any analytic tools to keep track of you.

https://git.eisfunke.com and https://forum.eisfunke.com naturally have to save data when registering. That includes your IP address, mail address and chosen username.

User content

https://git.eisfunke.com and https://forum.eisfunke.com allow you to submit content as a registered user. This content will, of course, be saved and be made publicly available where applicable.


Cookies are small files saved in your browser by websites. That is necessary to recognize you so that you don’t need to enter your password every time you open a website. https://git.eisfunke.com and https://forum.eisfunke.com use cookies for that purpose.


When you write me an e-mail, I of course have to process the mails data, including your e-mail address, to be able to read and reply to your message. Like every recipient of any e-mail has to.

Third parties

I do not sell, trade or transfer any data to third parties.

Your rights

According to the GDPR you have the right to

Please contact me if you want to utilize any of these rights and note that these rights are subject to restrictions and exceptions, e.g. when infeasible.
