Is curiyo.com Safe?

From a ZDNet article ( ***** ) about Curiyo: "Curiyo generates a streamlined news feed of relevant posts from various social media channels such as Wikipedia, YouTube, Twitter, and Reddit, on one smartphone screen with its new app." From the same article, "The app brings together videos, pictures, social media feeds, Reddit threads, and Wikipedia articles. It enables you to create a customised content discovery experience for your favorite items and is available in 15 different languages." The smartphone aspect is the latest offering from Curiyo whereas before it was a browser extension. It let's you do things like long-click on a word or phrase to bring up a search on that over wikipedia and social media. It actually makes more sense to me as a phone app. As such, I don't think Curiyo is tracking individual users much. They probably track searches you do so they can spot trending topics. That would allow them to locate and gather relevant information ahead of the next person asking, which would save them resources and let them seem more responsive.
