Linux, but I don't really mind MacOS, just that they're too pushy on restricting control while enabling their own services on your computer. With Linux I've been able to keep only what I use and remove the rest.

Never Windows, unless it's for work.

# Applications

I use Firefox with Ublock and Containers. I have one Container for Google stuff, another for Meta (Whatsapp is the de facto communication tool in my country). I was thinking of deleting cookies, but my workstation stay on for days, and it ultimately won't matter.

I don't have anything really essential on Google either (I use it only for collaboration and the odd emails).

# Online Storage

Backup is either as is (media files) or encrypted in some vaults. I use Syncthing for syncing with encrypted nodes online.

# Social Media

I only have my Linkedin and X account left, but I don't use them. No apps on my phone other than WhatsApp.

I don't really care about privacy other than trying to replicate the real world. If you really want to know about me, you can with some work, but I try not to publicize everything online.
