The Best Chat App For Privacy

In a world where our conversations have shifted from whispering secrets in the schoolyard to sharing memes in encrypted chat apps, one thing remains clear: privacy matters. But with so many options out there, how do you know which app is actually keeping your messages safe from prying eyes? Let's dive into the world of secure messaging, where we’ll unravel the mysteries of end-to-end encryption (E2EE) and see which apps are more private than your high school diary.

End-to-End Encryption: The Bodyguard of Your Messages

So, what is this fancy term everyone’s throwing around—end-to-end encryption? Imagine you’re passing notes in class (the good old days, right?). But instead of the teacher intercepting your note, only your friend on the receiving end can read it. That’s basically what E2EE does—it ensures that only you and the person you're chatting with can read the messages. No one else, not even the app’s company, can peek at what you’re saying. It’s like having a personal bodyguard for your messages, ensuring they stay between you and your friend.

But here’s the kicker: while your messages are safe, the app can still see who you’re chatting with and when. So, while E2EE is a strong defense, it’s not an impenetrable fortress.

Mainstream Chat Apps: Privacy or Just Good PR?

Now, let’s talk about the big players—WhatsApp and Facebook Messenger. They’re convenient, sure, but when it comes to privacy, they might be more like a fence than a wall.

WhatsApp: Ah, WhatsApp, the app that probably has more users than there are grains of sand on a beach. It’s easy to use, offers E2EE, and is owned by Facebook (now Meta). Wait, what? Yep, that’s where things get a bit dicey. Even though your messages are encrypted, Facebook still has access to metadata—like who you’re talking to and when. And let’s not forget that Facebook’s privacy track record isn’t exactly spotless. So, while WhatsApp might make you feel secure, just remember that it’s not completely out of reach for those with the right (or wrong) authority.

Facebook Messenger: Speaking of Facebook, let’s not leave out Messenger. This app, by default, doesn’t even offer E2EE—ouch. You have to enable "Secret Conversations" for that, which feels like a lot of effort just to keep your cat GIFs private. (I have to add that Facebook started implementing E2EE in the past 6 months, it's just not clear, when and how this actually happens.) And since Messenger is deeply embedded in Facebook’s data-gathering ecosystem, you can bet your bottom dollar that your conversations are feeding into the company’s massive data machine.

And here’s the thing: both of these and a bunch of other apps might be legally required to hand over information if the authorities come knocking. So, while your messages might be safe, your privacy isn’t entirely bulletproof.

More Secure Alternatives: The Good, The Bad, and the Private

Now, if you’re serious about privacy (and who isn’t, in these times?), you might want to consider some alternatives.

Signal: Let’s start with Signal, the poster child for secure messaging. It’s like that friend who’s always looking out for you. Signal is almost entirely open-source, which means anyone can inspect the code to make sure it’s doing what it promises—keeping your messages private. But not everything is as open as we’d like; some parts of Signal are still closed-source. And then there’s the phone number issue. You need one to register, which can be a bit of a privacy hiccup if you’re not into sharing your digits with the app. Still, Signal remains one of the most solid choices out there for those who want to keep their chats on the down-low.

Telegram: Next up is Telegram, the app that’s like the cool kid in school—everyone wants to hang out, but you’re not quite sure what they’re up to. You can register without a phone number (you need a workaround though), but here’s the catch: it’s not entirely open-source, and by default, your messages aren’t even end-to-end encrypted. You have to opt for “Secret Chats” if you want that level of security. And just when you thought it was private to chat, Telegram’s CEO Pavel Durov recently got arrested in France. While that doesn’t mean your messages are suddenly at risk, it does raise questions about the future. If the authorities decide to turn the screws, Telegram might have to comply.

Session: Finally, we come to Session, the privacy purist’s dream app. If Signal is your reliable friend and Telegram is the cool kid, Session is that mysterious new student who doesn’t say much, but you just know they’ve got secrets. Fully open-source, decentralized, and not needing a phone number to register—Session is the real deal. Just share your public key, and you’re ready to chat. Plus, it’s like the Marie Kondo of messaging apps, stripping all sent files of metadata (Signal does this too, to be fair). The only downside? Voice messages are a bit buggy and video calls are still in beta, so if you’re big on hearing your friends’ voices, you might need a bit of patience.

Conclusion: Choose Your Chat App Wisely

At the end of the day, the chat app you choose depends on how much you value your privacy. If you’re after the ultimate in security and privacy as well, Session is the way to go. If you’re looking for something more mainstream but still relatively safe, Signal is your best bet. And if you don’t mind a bit of risk for the sake of convenience, Telegram might work—just keep an eye on the news.

The biggest issue though is to convince your friends to use these apps as well. It's harder than you think, but still, Naomi Brockwell, one of my favorite privacy advocates, gives you some tips and tricks in her video.

As for WhatsApp and Facebook Messenger, well, they’re like using a picket fence to guard a secret. It might work, but don’t be surprised if someone peeks through.

So, next time you fire off a message, remember: it’s not just about who you’re talking to—it’s about who might be listening in.
