Notifications Security
Notification Content
Push notifications don't contain message text. When receiving a notification, the app establishes a secure connection with the server, downloads the message content, decrypts it, and only then displays it as a notification to the user.
The notification itself carries only service data, which the app uses to understand what happened. These are the chat, message, and sender IDs, the chat type and event type, and counters for unread messages and missed calls. For conferences — also the name and start time. The notification contains no message text, attachments, call content, or user data.
Hiding Notification Text
In all client apps, you can hide notification text in the settings of the app itself or the OS (see below).
