Right to be forgotten
The ability to require a service to delete what it holds about you.
Established in EU law and echoed elsewhere, it is the practical test of a privacy policy: a service that cannot delete you on request does not really know what it holds. In practice it covers the live record and usually excludes anything a service is legally required to keep.
It is distinct from account closure. Closing an account often only hides it.
Where Naven stands
Naven deletes an account and its content on request. Messages you sent into other people's conversations are a harder case, and the privacy page says which is which rather than implying everything vanishes.
