WhatsApp has announced more privacy protections on the messaging app. You’ll now be able to silence calls from unknown numbers, Meta CEO Mark Zuckerberg said Tuesday, as well as using a “privacy checkup” feature to see every privacy option on the app.

Silence unknown callers will automatically prevent spam, scams and unknown calls from going through. They’ll still appear in your calls list, but won’t actively ring on your phone.

For added privacy, here’s how to lock your more intimate WhatsApp chats.
