I've been using your browser for a couple months now (I think I saw it mentioned on Android Police if you're curious) and I've been liking it. It looks slick, and works exactly how I think it should. The one problem I have with it is one I'd like other opinions on, both for my curiosity and your benefit. Frankly, it's not my daily driver because I don't know who you are and don't trust you.

I'm also the developer of http://getgom.com (VPN as a Chrome extension using SPDY SSL proxies), and as a fellow Singaporean when our government openly does surveilance, I __completely__ understand where you are coming from. To be fair, I'm not sure how I can solve his problem though. Open sourcing could be a plausible answer. But fighting Google Play clones and what-not is really time-consuming and as an indie dev, m…
I would suggest you open source it under a non-commercial license. Also, take a look at how some successful android open source projects are run. In particular, I like XPrivacy (https://github.com/M66B/XPrivacy). This is an excellent app. Open source with optional purchase, similar to yours. Personally, I paid the $6 they charge because I'd rather not compile the src myself.
You've already had a lot of downloads and are an established app. Clones can't replicate that.. If you are a recognized dev on xda, with your own thread for discussion, feature requests, bug reports etc, no clones will be able to replace that aspect even if they can clone your app.
You should be able to get more downloads/purchases from privacy-aware users. And you can have donations for feature requests if you want.
Just some thoughts.. best of luck with the app!
