Topic: is this true?
There is indeed a 'history', its the personal privacy information they collect. What do you think they make a commission from? They make that commission from the collection of personal privacy information collected which includes the use history and searches from users of the Epic browser.
Claiming there is no 'WebRTC leak' issue with the Epic browser is deceptive misrepresentation. It has nothing to do with it because their proxy provider can still collect that IP information when one passes through the proxies used by the Epic browser, proxies designed to have the capability to collect such so their proxies provider (SpotFlux) can also make a buck from personal privacy information collection. Hidden Reflex, the creators of the Epic browser, has an agreement with SpotFlux that allows SpotFlux to also collect personal privacy information from users of the Epic browser. The Epic browser uses a version of the 'free' access to proxies which SpotFlux provides to its users of the free use of the SpotFlux vpn, SpotFlux tells you on their web site they collect personal privacy information from the users of the 'free' side of their service. SpotFlux is able to extract the real ISP IP address, even if one is on a VPN, from the connections through their proxies and connect it to the proxy provided IP address as in 'ISP-assigned-IP' = 'SpotFlux-driven-proxy-IP'.
No "Canvas" fingerprinting? What a joke. For those that do not know, "Canvas" fingerprinting is only one of a number of, what is called, browser fingerprinting techniques for tracking online users that allows websites to uniquely identify and track visitors using HTML5 canvas elements instead of other techniques. These other techniques still exist and are used, they do not suddenly vanish because the Epic browser might not include the HTML5 "Canvas" fingerprinting capability. The exclusion of "Canvas" fingerprinting does nothing to prevent browser fingerprinting techniques from being used nor does it prevent use of other techniques for collection of other personal privacy information collected through use of the Epic browser.
Saying there is no "Canvas" fingerprinting, WebRTC issues, no history, and a myriad of other things claimed for the Epic browser is like saying because one marble is removed from a jar of 100 marbles it means there are no more marbles in the jar. Saying these things for the Epic browser as a means to support the perception that it is somehow a 'privacy' browser is deceptive misrepresentation.
Its not really a 'privacy' browser and is 'misrepresented' by its creators (Hidden Reflex) to take advantage of 'privacy' paranoia so as to get as many to install it as possible so they can make a buck from the personal privacy information they collect from the users of the Epic browser. The more that use it the more money they make. Its a 'referral marketing' scam tool technique that's been polished up to look all bright and shiny to take advantage of 'privacy' paranoia. Its a reversal of that scam technique where one gets notified they have won a 'free' something and to collect it all they need to do is send some money to such and such. In the case of the Epic browser, they give you the browser for free and then make money from you using it. Its designed to collect personal privacy information from its users for the specific purpose of Hidden Reflex making commission revenue by selling that personal privacy information to 'third parties', advertisers, and the information broker industry.
Any company/entity that makes revenue (commissions in this case) from the use of their 'free' something is not really your friend, the bottom line is the money and the money will win every time.
