PHPlist HOSTED subscriber history

Is there a way to either search or download subscriber’s Campaign & Subscription histories from PHPlist Hosted?
I’m looking for
a) a way to identify those who’ve not read anything in ages (& then remove them) and
b) to know the most recent date on which each user subscribed/updated their own subscription (i.e. not when admin did so) for GDPR documentation/evidence.

Any suggestions gratefully received!
