In the last week:
I started using Syncthing. I was using cloud storage as a way of copying files from one device to another. Syncthing is so much better.
I signed up with Mullvad VPN yesterday.
Deleted my Surfshark account today which I signed up with over two years ago when I didn’t care about privacy.
Finally convinced my sister to start using Signal.
I started using the browser extension Chameleon. It automatically changes your user agent to make it look like you’re using another browser or OS. As usual, this should be used in conjunction with other addons such as uBlock Origin.

This actually drastically decreases privacy and makes you more trackable. The best thing to do with your user agent is to set it to the most common one and leave it at that. Anything else (especially an ever-changing one) is a much more uniquely identifying piece of information.
