Is it encrypted? The app-by-app guide
"Is it encrypted?" sounds like a yes-or-no question. It almost never is. Most apps encrypt something: your connection, their servers, one kind of chat but not another. The question that matters is narrower and sharper: can the company itself read this conversation? If the answer is "no, the keys live only on our devices", that is end-to-end encryption. Anything else is a promise, not a lock.
This desk answers that question app by app. Every guide carries a "Checked on" date at the top, because these facts move: in 2026 alone Instagram removed its encrypted DMs, X moved its chats into a separate app, Discord encrypted every call and WhatsApp put ads in its Updates tab.
The one-minute version (checked 5 Nov 2026): WhatsApp encrypts personal chats, groups and calls by default. Messenger encrypts personal chats and calls by default. Telegram encrypts only Secret Chats (one-to-one, opt-in) and calls; groups are not end-to-end encrypted. Instagram DMs have not been end-to-end encrypted since 8 May 2026.
How to read these guides
Each guide answers the questions people actually type, in the order they type them: is it encrypted by default, what about groups, can the company read it, what about backups, and what to do instead. Each ends with a short FAQ and a list of sources with dates. Where we could not find an official statement, we say so rather than guess.

Three questions that work on any app
- Who holds the keys? If the company can restore your chats on a new phone without anything you saved, it can probably read them.
- Does it cover groups? Many apps encrypt one-to-one chats and quietly leave groups in the cloud.
- What about the backup? An encrypted chat backed up to an unencrypted cloud is only as private as the cloud.
