In contrast to other "private" search engines (except for Presearch and SearX), it doesn't have trackers, or not nearly as many. This information can be verified by installing uBlock Origin and ClearURLs, which detect 0 and 2 trackers respectively, against for example DuckDuckGo's nearly 10 and 19. Other alternatives are SearX (No trackers AT ALL, still kinda user-friendly) and Presearch (A bit easier to use but a tiny bit worse for privacy, it has 1 more tracking element).
