In 2019 protecting our privacy is a serious issue and it is often difficult to find an ideal solution. The economy of Internet services revolves around data collection and data analysis, every kind of data regarding the users can be analyzed and generate profit. To survive in this kind of Internet - where the main currency is the users' data - it is important to trust the product we use. Open source softwares are a partial solution to this problem and they can help to protect our data. By allowing anyone to read and study the source code, users can see how their data are managed. Some examples of useful softwares used to protect our privacy are Tor Browser, Pi-hole, Tails and Signal.
