Don't try. There is no way to protect yourself from our absurd German privacy laws. (Except if you are the government, then nothing matters.)
Even the local residents' registration offices simply sell your private data for next to nothing to cheap ad companies.
..but if you are an US company, we hate you for the votes.
Default checked is still illegal. Even if it gives you a full screen of info. As someone who doesn’t read it and just clicks through the options should never lose any private data.
Everything that touches your private data has to be opt-in. Or it does not count as "explicit permission", meaning the upload, processing, etc is illegal.
So, again, what are you talking about?
