I found this brilliant website that gives you list of all sorts of tools to protect your digital life.
The software/services listed in the website are supported nearly on all operating systems. Windose, OS X, Linux, Android, iOS, and sometimes even BSD.
They range from
- OS, browsers, plug-ins, search engines
through
- IM chat, email clients, Disk encryption
all the way to
- Cloud storage, VPNs, DNS services
If privacy means anything to you then this is really worth a read. https://www.privacytools.io/
