Methodology
- Data comes from devices connected to Kudu Cloud and seen in the last 30 days, in organisations that have not opted out of anonymous statistics. Devices that use only the free desktop app do not send this data.
- A figure is published only when enough separate organisations and devices contribute to it. Device counts are rounded. No hostnames, file paths, or per-device data are published.
- Kudu Cloud is used by IT teams, repair shops, and individuals who chose to manage their computers. This is a sample of Kudu users, not of all computers.
- Junk figures are what a scan found, not what was deleted. Space recovered is the sum of completed cleanups.
