And they're explicitly tracking and logging it all to their servers:

> With the Flattr button it was only possible to flattr creators that joined Flattr. The new extension does not use the button so it does not need to know if there is a signed up receiver or not for flattrs. So simply put, if there is an owner they gets your money, if not the flattrs become the statistics we need to convince the creators.

Yikes. Don't use this, they clearly don't care about privacy.

That is just plain wrong. Check the privacy policy: https://flattr.com/files/privacy_policy.pdf

The extension keeps everything locally, only the information necessary to make payments is transferred. There is even a blacklist in place that prevents any information about sensitive sites (online banking, mail accounts, other adult content) from ever being stored.

Here is a blogpost about it: https://blog.flattr.net/2017/06/key-elements-of-the-new-flat...

Then how can they be collecting statistics about non-participating sites?
