This add-on is built and maintained by workers at Aarhus University in Denmark. We are privacy researchers that got tired of seeing how companies violate the EU’s General Data Protection Regulation (GDPR). Because the organisations that enforce the GDPR do not have enough resources, we built this add-on to help them out.

Nice!
