Private messaging: what to use instead of texts, WhatsApp, and Messenger
Texts, WhatsApp, and Messenger all feel private. Most of them aren’t, at least not in the ways that matter. Here’s a plain-language look at what each one actually protects, and the one app worth switching to.
Two things decide how private a messaging app really is. The first is end-to-end encryption, which means a message is scrambled so that only you and the person you’re writing to can read it, not the company carrying it in the middle. The second is metadata, the record of who you talked to, when, and how often. You can have perfect encryption and still leak a complete map of your relationships through metadata. A genuinely private app protects both.
Here is how the common options compare on the things that actually matter.
| What matters | Signal | Text / SMS | Messenger | Telegram | iMessage | |
|---|---|---|---|---|---|---|
| Encrypted end-to-end by default | ✓ | ✗ | ✓ | ✓ | ✗secret chats only | ✓ |
| Hides who you talk to (metadata) | ✓ | ✗ | ✗ | ✗ | ✗ | ✗ |
| Open source, independently audited | ✓ | ✗ | ✗ | ✗ | ⚠app only | ✗ |
| Run by a nonprofit, not an ad or data business | ✓ | ✗your carrier | ✗Meta | ✗Meta | ✗ | ✗Apple |
Last reviewed June 2026. Encryption and ownership change over time, so we keep this current.
Signal is the only one that protects all four. It’s free, run by a nonprofit instead of an advertising company, and works on any phone.
Why Signal, specifically
Notice that WhatsApp and Messenger do encrypt your messages now, so the chat content itself is genuinely protected. The problem is everything around the message. Both are owned by Meta, both still collect metadata about who you contact and when, and you can’t inspect how they really work. Signal collects almost nothing, publishes all of its code for anyone to audit, and is run by a nonprofit foundation with no ads and nothing to sell. That combination is why security professionals recommend it.
Plain texting is the weakest option
Regular text messages (SMS) have no encryption at all. Your phone carrier can read them, store them, and hand them over. iMessage is better between two Apple devices, but the moment you text someone on an Android phone it quietly falls back to plain SMS. If privacy matters, don’t let the default texting app be where sensitive things get said.
Making the switch easy
- Install Signal on your phone and computer. It uses your existing phone number, so setup takes a few minutes.
- Invite the people you message most. Private messaging works best when your circle is on the same app.
- Turn on disappearing messages for sensitive threads so old conversations don’t pile up on either phone.
- Move at your own pace. Keep your normal apps for everyday chatter. You don’t have to switch everything at once.
Going further: messaging with no phone network at all
If you ever need to communicate when the cell network is down or can’t be trusted, during an outage, in a crowd, or off the grid, Meshtastic is worth knowing about. It’s a small, inexpensive radio that pairs with your phone and sends encrypted text messages device to device, with no carrier, SIM card, or internet involved. It’s more of an emergency and enthusiast tool than an everyday one, but it’s the clearest example of communication that no company can switch off or listen in on.
Email follows the same logic. See our guide on switching to encrypted email for the inbox side of the same problem.
