But Is It Safe?, an open-source messaging app that includes video calling, has been making waves with promises of never-before-seen security for messages and calls. Unlike other instant messaging (IM) apps, works over a P2P network.

By protecting all traffic on the app with superior encryption, promises you an easy way to stay in touch with your friends, family, and coworkers without worrying about your chat history being sold, censored, or hijacked.

But how safe is to use, really? Is there any truth to the rumors that using the service exposes your IP address? If so, what risks does that exposure create?

We put to the test to see if it lives up to the hype, if the alleged vulnerabilities are real, and how you can make sure your data and devices are completely safe when you use it.

Features of uses a peer-to-peer (P2P) network, which means that data is channeled through a vast network of user connections. There's no central server where messages are stored – and potentially read or collected by third parties.

The software is free to use, but also readily available for anyone to modify or share since it’s open source. There are seven different versions, with a range of support for Windows, OSX, Android, and iOS, as well as alternative clients for Linux and BSD.

All of the clients support basic features: text messaging, audio and/or video calling, group chats, file transfers, and desktop sharing. Some clients have unique additional features – the Toxygen client, for example, offers faux offline file transfer.

You can download and use any of the clients at no cost, but bear in mind that they’re all still in development. That means you can expect exciting new features in the future, but some bugs in the present.

The best part? You will never see ads on any of the primary seven clients!

Potential Risks of Using’s developers make bold claims of offering game-changing security in a private messaging service. Critics have answered with charges of major vulnerabilities that put your identity and data at risk.

As usual, the truth lies somewhere in between.

Shortcomings of’s encryption

First off, we can offer some reassurance. We’ve reviewed’s encryption protocols, and they are advanced and rock solid.

But as we’ve seen with the security failures of other messaging services like WhatsApp, the phrase “end-to-end encryption” leaves many big questions unanswered, such as: What data is encrypted? And more importantly, what isn’t?

In the case of, the encryption methods don’t hide your IP address, and that raises some legitimate concerns. Anyone you connect with via can see your IP, which means they can easily find out your exact location.

Even if you trust your contacts with your IP address, the information would be available to anyone who accesses their devices, including hackers. The risk grows with group messaging or video conferencing.

Concerns about’s network structure

One of the big selling points of is decentralization. A P2P network means there is no hub server where data is stored, which in turn means greater user privacy. However, some users have alleged that is not fully decentralized, after all.

More importantly, even a fully decentralized P2P network creates risk.

Specifically, using any P2P network involves some risk of DoS, malware, or spyware attacks because your connection is accessed by others on the network. This is one reason why many P2P services recommend always using a virtual private network (VPN).

Further testing is needed

Without doubt, the creators of have put many hours and a lot of effort into giving you an alternative to mainstream IM apps that have known security issues.

However, with all apps still in development, there’s no way to fully assess the risks. Fortunately, you don’t have to take any chances when you try out, because there’s an easy way to protect your devices and data right now.

Why You Should Use a VPN with

For all the good things it has to offer, can’t do one crucial thing – mask your IP address. This shortcoming is the root of all risks associated with using the service and one of the major reasons to use a VPN.

When you use a VPN, your true IP will be replaced with one matching the remote server you use. No other user, not even a cybercriminal who sneaks onto the network, could trace your traffic back to you.

This protection is especially important in countries with heavy government internet surveillance. By connecting to a server in another country, you can keep your use of completely invisible to the authorities.

We recommend using a well-established VPN that offers DNS leak protection and a kill switch. The kill switch stops data transmission if your VPN server connection drops for any reason, ensuring that your IP will never become visible.

DNS leak protection ensures that none of your data will make its way onto the public internet, where it would be vulnerable to eavesdropping by your ISP, government surveillance, or hacking.

The best VPNs strongly encrypt your messages and everything else leaving your device, while providing protection against tracking and malware. Extra layers of encryption on top of the encryption provides mean extra security.

Make sure to choose a VPN with lightning-fast network speeds to ensure easy messaging and smooth video calls. Finally, since is a P2P network, it’s best to choose a VPN that allows P2P activity, particularly if you exchange files.

You’ll find all of these features with any of our top-rated VPNs listed below.
