Note there is no current system that deletes prospects after 90 real-world days.

We have, however, issued a warning that at some point in future prospects might be deleted after 90 real-world days of inactivity so that, in future, we don't have to store data indefinitely as data storage is not free and the project was not intended to have very significant amounts of data stored indefinitely.

So to confirm, the 90-day is simply an indication that at a future time it is possible that prospects not accessed outside 90 real-world days are not guaranteed to always be on the server forever.

As another poster noted, with decentralization even this potential issue will not exist.
