So, if you want to do something positive, try the Ecosia engine. Each search increases their contribution to saving the planet. At least statistically. It also encrypts your search queries, deletes your logs, and does not sell your data regarding your privacy.
However, it should be noted that the company has few proprietary technologies. Rather, he uses Microsoft Bing to work behind the scenes.
