These apps can help keep prying eyes away from your conversations

There is a growing desire to keep one’s messages private. Some users are concerned about hackers, or worry about foreign or domestic government surveillance, but most people just agree with the general principle that what you say in your chat conversations ought to stay between you and the people you chat with.
It’s not a pleasant idea to think that your messages could be archived for perpetuity on a large company’s server or analyzed by some algorithm. The quest for privacy has birthed a whole generation of apps that promise to give you exactly that. Services like Telegram and Signal have turned the phrase “end-to-end encryption” into a popular discussion. We’re here to help you figure out what this is all about and which apps to try.
A little background on encryption
Before we look at some specific apps, here’s a very brief explainer. Essentially, end-to-end encryption means that only the sender and the recipient can read the message. The message is encrypted on your phone, sent to the recipient, and then decrypted. This prevents prying eyes from the telecom providers, government agencies, and even the company that hosts the service itself from being able to read your messages. This means they wouldn’t have the ability to hand over messages even if they were subpoenaed by a government agency. And if a hacker broke into the messaging service’s servers, they couldn’t get at your conversations.
The desire for end-to-end (E2E) encryption isn’t just about those who don’t want the NSA to spy on them. In practice, it’s just about a basic sense that messages should be private. With that in mind, you have to be aware that just because something has the word “encrypted” doesn’t mean it is end-to-end encrypted.
The services we’re looking at here all feature end-to-end encryption.
One of the most popular apps in this space is Telegram. It’s been a pretty hot app for a couple of years, which is like 20 years in app time.
The most painstaking part is you need to invite all of your contacts into your new, secret chat world through the app’s navigation menu. It’s the biggest problem with using over-the-top services, as it doesn’t have the ubiquity of SMS messaging.
Once you’ve done this, you can message people individually or create group channels for talking with an unlimited number of other users. The upside here is you can escape the limitations of MMS messaging that usually caps you at a particular number of people.
The interface is a little barren, but Telegram makes the list for its robust privacy and offering native apps for iOS, Mac, Windows, the web, and of course Android.
Signal’s claim to fame is that it’s the preferred messaging application of Edward Snowden. It’s among the easiest to set up, as it automatically authenticates your number and can even be used as your default SMS app.
As with Whisper, you can create a group for private banter with an unlimited number of other users. Signal also makes phone calls, which I found to be very clear when testing it out in a couple of different cases.
Signal isn’t optimized for tablets, but the company says that’s on the product roadmap.
Another good option is Wire. It offers some fun messaging tricks, like the ability to doodle, share your location, send images, or record a video. The app also includes a chat bot, Anna, which offers somewhat useful answers to various questions about how to use the app.
You can optionally create an account with your phone number, which makes setup and account deletion easy. Wire is great for one-on-one chats if you would prefer conversations with someone be off the record.
You also can’t forget about the uber-popular WhatsApp. Like the others on this list, it promises end-to-end encryption so your messages stay private. The biggest advantage is that the service, which is owned by Facebook, has more than a billion users. There’s a very good chance you won’t have to convince all your friends and family to download the app.
That shouldn’t be discounted, as one of the pains of moving to a messaging service is convincing everybody to jump aboard. However, WhatsApp is now owned by Facebook, a connection that could make some wary, especially since the social network recently announced it’d be using some account information, including phone numbers, from WhatsApp.
If you want to see messages disappear before your eyes, then Dust (formerly Cyber Dust) is the way to go. The brainchild of Dallas Mavericks owner Mark Cuban, the messages can disappear in 24 hours or as soon as they’re read, based on your preferences.
The company spells out its encryption policy, and includes a couple other features to ease your mind like chats that don’t show usernames, so even if someone took a screenshot it couldn’t necessarily be attributed to you.
The best app for you is going to depend upon your needs. Secure messaging is a huge and growing area of consumer interest, but it’s worth the effort if staying secure is what you’re after.
