Piriform CCleaner Telemetry

CCleaner is a popular cleaning tool that has recently added telemetry. Piriform explains the telemetry as:

As the world’s favorite device cleaning and optimization company, we want to keep your devices working better, for longer, and help protect your privacy online.

In order to do this, we are required to collect some data so we can offer you the best PC cleaning, optimization and privacy tools available. Our Privacy Policy documentation, and in particular our Products Policy, covers the data we collect and what it’s used for and how it is stored.

The step to add telemetry, the way users were (not?) informed and the availability of options to disable it caused CCleaner to appear on this list.

As a CCleaner Pro user, you can disable this in its Options > Privacy.
