Smart Cookie Secure Web Browser is a lightweight, basic and secure web browser that uses less than 8MB of space.
There is an Incognito Mode which can be enabled and stops web trackers completely. As well as this, the user agent (your web "fingerprint") is the same as every other Smart Cookie user so websites can't track you.
Smart Cookie is ad-free and always will be. There is also an ad blocker included which is enabled by default.
