Xtreix Oh I didn't read all the pages. Ctrl+F did a lot of heavy lifting, so it was mostly a matter of parsing through the keyword hits to see what the context around them were. Which as I said had nothing to with GrapheneOS and mostly concerned "where/why did you have this phone and using Signal to talk to these people?".
I also have the fortune of both speaking Swedish and rather liking doing stuff like this so I'm glad it was of use :)
