Absolutely not. M-Lab tests are designed to protect your privacy by measuring only synthetic traffic (“fake” traffic generated by a test solely for the purpose of measurement) between your device and an M-Lab server. M-Lab’s Privacy Policy and Acceptable Use Policy prohibit the collection of personally identifiable information and private user traffic.
M-Lab collects and publishes all test data, which include the IP address assigned to your device by your Internet service provider (ISP). However, this does not include any personal information about you as an Internet user, where you browse, or any other details that could be used to associate you with your history of tests.
