When it's not mentioned I just assume it's US only. Which is usually the case.
IIRC Tiny came out of MetaLab and MetaLab is Canadian.
Don't know if they might be registered elsewhere though. They probably are.
If so, no wonder. I've done a lot of data analysis contracts over the years and they were, by far, the most concerned about protecting user privacy way before it was cool. Tiny sounds just like their values.
