With real-time spam detection, Messages makes chatting easier and safer. This feature works with your message data while keeping your messages private. And it’s optional—so you're in control.
How spam detection works
How we protect your data
We use data without personally identifying you.
When Spam protection is on, Google temporarily stores the phone numbers of received and sent messages for numbers that aren't in your contacts. This helps Google identify spammers.
This data is not linked to you or to identifiers like your name or phone number, which means Google doesn’t know who you’re messaging. Your message content is not seen or stored by Google as part of this feature. Learn more about reporting spam or blocking a number.
You're in control
Spam protection is turned on automatically, and you’ll be notified when this happens. You can turn it off anytime in Settings:
- Open the Messages app .
- Tap More Settings.
- Tap Advanced Spam protection. You'll only see "Spam protection" if it's available on your device.
- Turn Enable spam protection on or off.
