In Germany an Imprint for a paid service is mandatory and after the ToS it seems like this is a product from a company in France? (I believe there are similar laws in France?)
> The Telemediengesetz (German meaning "Telemedia Act") requires that German websites disclose information about the publisher, including their name and address, telephone number or e-mail address, trade registry number, VAT number, and other information depending on the type of company.
The relevant German laws (搂5 TMG and 搂55 RStV) are fairly vague, so lawyers recommend publishing an Impressum if your website contains any commercial content (for example, ad banners) or any journalistic content (for example, blog posts).
