A computing device may place or receive a call to establish the call with a caller. The computing device may determine whether a user of the computing device has configured the computing device to analyze call data from the call. While the call is ongoing, the computing device may analyze the call data from the call when the computing device has been configured to allow the analysis. The computing device may determine, based on contextual information associated with the call, whether the call satisfies a scam call threshold. Responsive to determining that the call satisfies the scam call threshold, the computing device may output an alert indicating the call with the caller is a scam call. The computing device may terminate the call with the caller in response to receiving user input to end the call.
