> It is weird that...

Doesn't strike this USian at all as weird. This describes most online entities that I interact with. Plus, there's always the site's contact form that you can use to ask for the information you want.

What makes me trust it a whole lot are this triplet of facts

1) AFAICT, neither their privacy policy nor their terms of service have been changed in more than a decade.

2) They do not require you to give up your right to access the courts in order to use their service.

3) The backend code is open source.
