Private messages really aren’t so private, and Peter Sunde, co-founder and former spokesperson for BitTorrent search engine The Pirate Bay, isn’t happy about it. So Sunde has worked with a small group of developers to raise money for a fully private messaging app.

The iPhone and Android app will be called Hemlis, the Swedish word for “secret,” and utilizes end-to-end encryption to ensure that only the two people carrying on the text conversation will have access to its data. Unlike traditional messaging apps, which leave data trails that companies and the government can access, the security within Hemlis means that no outside force — not even Sunde and his team — would be able to see a message’s contents.

Not suprisingly, Sunde and his team aren’t planning on a traditional ad revenue model for their new free app. The crowdfunding campaign for the app, which allows users to pay in cash or Bitcoin, starts at $5 to unlock the extra features in the messenger. Spending $10 and above will allow access to pre-registering usernames — and a donation of $500 includes a fundraiser mention in the app and hundreds of unlock codes. But fundraising is still early, and there’s no release date for Hemlis.

While encrypted text messages may seem excessive to most people, texting apps do take advantage of demographic and metadata to appeal to advertisers. Sunde has been very vocal about the NSA scandal, and his app is aimed at a relatively small group of like-minded users that are not only alarmed about the levels of surveillance and data capture — but who are also exercised enough to do something about it. It is likely to appeal to the same kinds of people that use networks like Tor and search engines like DuckDuckGo.
