Can cleaned data be recovered?

We often get the question, "If I clean my system with CCleaner for Mac, can the data be recovered later?"

The answer is that this depends on the skill and resources available to the person attempting the recovery, as well as what settings you used in CCleaner for Mac when you cleaned.

If you run CCleaner for Mac with its default settings, you'll thwart most attempts at recovery, but you can decrease the chances that someone will be able to recover files as follows:

  1. Use secure deletion - the more passes that CCleaner uses to overwrite the data, the harder it will be to recover.
  2. Wipe free space on your volumes.
