Am I being dense… How or where are install instructions for Debian based distros?

Proton Pass is a thing mate take a look it might suit your needs

I was in same boat, I ended up going with Tabby for my Linux clients.

It is by no means a like for like replacement BUT you can someshat backup and sync profiles and config across machines.

Is a huge shame it doesn’t work on android though

Strava, komoot and a calorie tracker that’s actually decent

Komoot and strava… General route planning and teavkinv software…
