Feature Request: Filter the — (for users without login data)

Heya,

Great plugin! Love how lightweight it is. One little request: Could you add a filter around the output for when there’s no data for a user?
My use case is that I want it to say like “(No logins since October 9, 2026)”, so people know when we started tracking the data and have a better idea of what not having data means.
Cheers!
