Privacy is the word of the year, according to Dictionary.com, which comes as no surprise after all the NSA revelations (one of the latest being that they're tracking you through cookies), the requests for reforming privacy laws, but also as part of a bigger trend towards taking back the privacy of our communications with apps like Snapchat, too (granted, Snapchat isn't really private, since it doesn't encrypt your communications end-to-end, but at least private in the anti-Facebook sense).
The makers of the Dolphin browser seem to have caught on to this trend, and are announcing Dolphin Zero, a mobile browser for Android, that automatically deletes your sensitive data such as browsing history, form data, passwords, website cookies and cached data & files, upon exit.
This is a good start, but we could already do this ourselves with any browser. Of course, most of us never take that action, simply because it's too cumbersome, and don't even think about it when we exit our browsers. So making it so the data is deleted automatically without you even thinking about it, does significantly improve everyone's privacy.
This is not where the privacy features end, though. They've also added the option to use privacy-oriented search engines like DuckDuckGo (and hopefully Ixquick, too, soon), which I say is mandatory to be set to default for privacy-oriented browsers, because much of the tracking is done through search engines.
They've also enabled Do Not Track by default, which I still think it's mostly useless since advertising companies haven't agreed to respect it. The way DNT works is that you're sending a message to advertising companies letting them know that you do not wish to be tracked. However, the companies can easily dismiss your request. DNT doesn't actually block companies from tracking you, which is what many people still think it's what it does.
So I hope the people behind Dolphin also consider adding functionality like Ghostery, which automatically blocks tracking cookies as you receive them. This is something that's already done by browsers like the Epic Browser, which is a Chromium-based highly privacy-oriented desktop browser. Hopefully, Dolphin Zero will try to replicate much of its privacy functionality in the future, while adding other functionality of their own, because it's great to have this sort of browsers as an option.
