Appreciate the honesty, friend. You are awesome.

I never got into the wearables but I for sure use my phone. My phone is degoogled so I use health apps from F-Droid which help with tracking some metrics which also sync with my Nextcloud instance only, or do not request to have internet or network permissions.

I do think, like you that having some into IS useful and in that no government Left or rRght leaning should have your ior my nfo. That's just 1984 -type nightmare fuel.
