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 am using https://github.com/39aldo39/Flym-DecSync. It is not updated recently. But it is the best I got from Fdroid after trying almost all.
