Short version: this site asks nothing of you and passes nothing about you on.
What you fill in (name, email address, subject, message) is used to deliver your message to info@brilman.me and to be able to answer you. Not for anything else, and it is not shared with third parties.
The web server keeps the usual technical log lines (time, requested address, error codes) so that faults can be found. They are not used to track or recognise visitors.
Some addresses within eanna.house are not public but protected by a login. A session cookie does apply there — see the cookie statement. Those parts are not meant for visitors.
