This website generates a link based on your preferences to use the RaPla Middleware which filters unwanted events.
Please only select a Wahl- / Profilmodul if you are in the 5./6. Semester and have any of these as otherwise, the middleware might not work as expected.
Of course, I try my best to only exclude the events you want to have removed, but of course I can't guarantee that this tool works exactly as expected all the time. Please don't only rely on this tool working perfectly.
If you have any questions or bugs, contact me via one of the options on p4ddy.com
Here is the link that you can use for importing RaPla into your iCloud etc. calendar (click to copy):
