Most Mac cleaning apps cost $30-50/year, collect usage data, and show upsell popups. PureMac does the same job for free, runs entirely offline, and the source code is right here for you to audit.
- 100% free - no trial, no premium tier, no subscriptions
- 100% private - no analytics, no telemetry, no network calls
- 100% native - built with SwiftUI, no Electron, no web views
- 100% open source - MIT licensed, audit the code yourself
- Signed & notarized - Apple Developer ID, no Gatekeeper warnings
