In this video, I put Signal vs Telegram head-to-head the way it should be done: not with hype, but by tearing down the fundamentals. I break down who owns each app (Signal’s nonprofit foundation vs Telegram’s private, for-profit structure), then I dig into what actually matters for privacy—encryption defaults, protocol choices, and what happens to your messages when they hit a company’s servers. Signal is the gold standard here because it uses the Signal Protocol with always-on end-to-end encryption for messages, calls, and files, plus perfect forward secrecy. Telegram is the feature giant, but the privacy story is more complicated. Most Telegram chats are “cloud chats,” meaning Telegram holds the keys while messages sit on their servers, and end-to-end encryption is something you have to opt into via Secret Chats (and those are device-specific). I also cover metadata and logging: Signal keeps it minimal (basically just your number and timestamps), while Telegram can collect things like IP address, devices, and username history—and its policy has shifted to allow sharing IP/phone with authorities under certain court orders. My takeaway is simple: pick based on your threat model. If you want maximum privacy, Signal wins. If you want massive groups, channels, bots, and seamless multi-device syncing, Telegram can work—just use Secret Chats when it counts and pair either app with a VPN to protect your IP-level metadata.
