Looks like PrivateStorage is finally launching later this year.
"PrivateStorage began as a joint venture between Least Authority and Private Internet Access. Together, we facilitated user testing as we investigated improvements to increase the usability of the application. At the end of 2020, the two companies mutually agreed to change their relationship and PrivateStorage is now 100% owned by Least Authority."
