Keyboard Browser

good app just needs updates

I'm using this on my S10 since the death of my keyone a few weeks ago. I would pay for this if I could get dark mode. I prefer it over both the Samsung and Google browsers. Much better for one hand use. Please add dark mode. Paid for ad removal, dark mode is great. One problem now though. Changed phones again, lost all my book marks and am now on a version with ads. How can, I get my ad free version back?
