New desktop setup and taking ownership of data

I have switched to a new desktop setup . An iPad mini and a Dell Venue 11 pro (dual booting Windows 10/Ubuntu/Kali).

Utilizing Nextcloud for sync , Bitwarden (to my own self hosted bitwarden_rs server) for passwords, Firefox for browsing (using Chrome not signed in for sysadmin portals, Firefox for general net browsing). No account in Firefox, planning to setup the private firefox sync server. I keep iCloud turned off on iPad/iPhone for security reasons.

More details later (and I will finish up my previous posts on enterprise data center build out).
