- Their webpage is available in several languages of EU countries (e.g. German) and they offer a service (for free), so they have to fulfill GDPR
- They store the user's phone number (and optionally more), so they process private information, but they don't name an EU representative located in the EU
- They don't tell the user the rights like deleting data, making requests and so on.
So do I miss something or is Signal in violation of GDPR?
