@paequ2 It has been so long since I started using JOSM that I don't really know what's tutorials are the best. HOT did a two minute introduction to building tracing that's linked from the wiki: https://www.youtube.com/watch?v=DcKewl94jR4 (skip the HOT specific bit)
LearnOSM has a longer written introduction to JOSM here: https://learnosm.org/en/josm/
@Koreller did a very good collection of GIFs suggesting efficient ways to trace buildings with the building tools plugin here: https://www.openstreetmap.org/user/Koreller/diary/404988

It also looks to the tile providers privacy policy.
Only F-Droid would take the stated purpose of an app and warn you about it as an anti-feature, but here we are.
