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.
Finally switched from from Windows to Linux (specifically EndeavourOS, an Arch-based distro with a GUI installer).
I also bought a new phone, on which I intend to install GrapheneOS and distance myself from Google's ecosystem.
I signed up for Proton Mail.
LibRedirect browser addon to switch to privacy-respecting frontends for popular websites.
