Hello Dave
Thanks for the reply, I'm not sure what happened with me missing the initial installation screen but either way, I was not best pleased when I had realised what happened.
On the GDPR point, you're quite right that the GDPR is concerned with the processing of personal data, however, the Privacy and Electronic Communications Regulations covers direct marketing which requires consent for any electronic marketing. Historically, there was no definition of consent in the PECR but instead referred to the ePrivacy Directive which in turn referred to the Data Protection Directive.
