I use OneDrive, but there are plenty of options - Dropbox etc

I second Joplin - works well on Linux Mint and on my Android phone and syncs seamlessly

Hello! I grew up on Portland, so perhaps it is very regional. I think we used the term specifically for the large black kind that roll up, the other brown/grey ones that don’t we called Wood Lice too!

Growing up in Dorset, UK we always called them “Chiggy-wigs”
