Realistically, it is really hard to protect your privacy online unless you decide to stop using 3rd party services like email, calendar, file sharing, social networks, etc. All these services collect enormous amounts of information about everyone. The internet protocols (TCP/IP, HTTP) have not been designed with privacy in mind and the only way to ensure real privacy for internet users is to start from scratch and rethink the whole stack. Unfortunately, it is not going to happen thus users pretty much have a tradeoff: either to accept privacy violations from various parties or to (significantly) limit the use of internet services.
