This browser sounds interesting, but it collects browsing history. While it claims this is kept anonymous, I would think it would be anything but anonymous if you were not exceedingly careful how you used the browser.

From the apps privacy policy (https://insightbrowser.com/privacy):

" Some information — such as your Internet Protocol (IP) address, browsing history and/or browser and device characteristics — is collected automatically when you visit our App. However, this information is anonymous and is never linked to your personal information."
