Lenovo Customer Feedback Program can be preinstalled on Lenovo systems and communicates telemetry data over the Internet.
Lenovo itself describes this telemetry:
In Windows 8, 8.1 and 10, Lenovo may also include an application in the preload called “Lenovo Experience Improvement”. This keeps track of what preloaded applications are uninstalled within the first 90 days of system use. The data is uploaded to a server in the United States at various times during the first 90 days. The data does not include any personally identifiable information (PII)
It can be argued that transmitting data always involves IP addresses, which are regarded as PII by many legislations.
This immunizer is available for users of the Plus version. It will only be shown within Anti-Beacon if Lenovo Customer Feedback Program is installed.
