In order to answer this question, we need to provide you with some background information.
Active Monitoring is concerned with system and browser monitoring. It is a mechanism that triggers different actions that help keep your computer clean. For example, it activates automatic cleaning when you’ve reached a certain level of junk or when you close your browser. It also tells your system when a new CCleaner update is available, as using the latest version of CCleaner will ensure that your system gets the best clean. It does not, and has never, reported any data to us.
In version 5.45, as part of our ongoing mission to improve CCleaner and deliver a better customer experience, we introduced some features aimed at providing us with better aggregated, anonymous usage data that we can use to spot trends to improve our software, fix bugs more quickly and deliver a better user experience. CCleaner does not report any personally identifiable information.
Although the reporting of anonymous usage data was a completely separate function to Active Monitoring they shared the same underlying mechanism, meaning in v5.45 it wasn't clear when Active Monitoring had been disabled.
How to resolve this issue
After listening to your feedback, version 5.46 resolved this issue by separating cleaning functionality (Active Monitoring) from analytics reporting, providing more user control options and renaming some features to make their function clearer. With this version we also released a Data Factsheet which describes the data reported by CCleaner, why it is reported and what it's used for.
We recommend that you read our Data Factsheet and update to the latest version of CCleaner.
