Android/iOS/Web: Encrypted chat service Gliph already gives you disposable emails and secures your mobile messages. Its new GliphMe service lets you chat privately with anyone, even if they're not using Gliph.
Here's how it works: GliphMe lets Gliph users create a short link that they can give to anyone they want to talk to privately. When someone clicks that link, they're presented with a private Gliph chatbox that they can use to communicate with you instantly. They type, and as they send their message, it's routed to you in Gliph, on your phone. When the message comes in, you'll get a push notification that a new encrypted message has arrived.
From there, you can respond and chat with them like any other IM service or texting app — only they're using the web interface, you're using your phone (and getting notifications when they send messages), and the conversation is completely private. Hit the link below to give the new feature a try, or sign up for Gliph if you're not currently a user.
