Can Apps See My Text Messages?
On iOS, no third-party app can read your SMS messages — Apple's system restricts this. On Android, apps with READ_SMS permission can read all your texts. Messaging apps like WhatsApp can read messages sent within their platform, but end-to-end encryption means even WhatsApp cannot read message content. Signal collects the least metadata of any major messaging app.
What Messaging Apps' Policies Say
Cannot read content, collects metadata
WhatsApp uses end-to-end encryption — WhatsApp cannot read message content. However, their privacy policy states they collect metadata: who you message, when, how often, and your device information. This metadata is shared with Meta.
