When people think about private communication, names like Zoom and Signal often come up. But what does privacy actually mean in the context of video calls—and do these apps really protect your identity, metadata, and conversations?

In this post, we break down how three leading platforms—Zoom, Signal, and EXTRA SAFE—compare across key privacy dimensions.

What "Private" Actually Means

To evaluate privacy in video apps, we looked at:

• Does it require registration or a phone number?

• Are calls end-to-end encrypted?

• Is metadata collected or stored?

• Can you use it without downloading an app?

• Does it use peer-to-peer (P2P) architecture?

• Are encryption keys stored locally or on company servers?

Why EXTRA SAFE Wins for Privacy

EXTRA SAFE is the only app in this comparison that:

• Requires no signup, phone number, or email

• Is built entirely on P2P technology

• Stores nothing—not even metadata or call history

• Uses asymmetric encryption, with keys created and kept on the user’s device

• Doesn’t require the person you're calling to install anything

It’s not just encrypted—it’s anonymous, decentralized, and server-free.
