Covert Browser’s been around since November, but apparently doesn’t support cookies or POST requests. (Easy way to test POST by itself: try a search with https://duckduckgo.com/lite/ or the regular DDG with the "Address Bar: No (POST)" option, it doesn’t work.)
Also figured an open-source clone would be more beneficial/trustworthy to really paranoid folks (who could even go as far as build it themselves).
