With real-time spam detection, Messages makes chatting easier and safer. Spam detection 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, Messages uses machine learning models that operate on your device to detect known spam patterns in your messages. Messages doesn’t share or send the content of your messages to Google servers unless you report messages as spam. Even when you don’t have a data connection, Messages can detect spam on your device.
Depending on the features that you have opted into, spam information is sent to Google anonymously to improve spam and abuse protection. Google temporarily stores the phone numbers of messages you receive from people that aren't in your contacts, your country, and other non-identifying information. Google doesn't store any data on persistent identifiers like your name or phone number, which means Google doesn't know who you're messaging.
Messages combines the available data from your device and Google servers to improve spam detection. This process happens on your device.
