What DiskMapper collects
Nothing. DiskMapper contains no analytics, no telemetry, no tracking, and no third-party services. It makes no network connections except:
- Update checks (Sparkle framework) against
diskmapper.app, once a day, which transmit only the app version being checked. You can disable automatic update checks in Settings. - The "Buy Me a Coffee" link, if you click it — this opens your browser and takes you to a third-party donation page. Nothing is sent unless you click it yourself.
Our web server counts downloads, update checks, and coffee-link clicks in aggregate — no identifiers, no cookies, no IP addresses stored.
This website uses Google Analytics
Added August 2026. It is a third-party script and it does set cookies. It is here so that "did anyone find this page?" has a number for an answer rather than a guess, and what Google collects through it is described in their privacy policy.
It is the only third-party script on the site: no ad pixels, no retargeting, no social widgets, nothing sold to anyone. Any content blocker stops it and every page works the same without it. Until August 2026 this page said the site used no third-party services and set no cookies — that was true then and it is not true now, so it no longer says it.
None of this touches the app. DiskMapper itself still contains no analytics, no telemetry and no third-party services, which is the claim that actually matters.
What stays on your Mac
Everything DiskMapper knows lives locally and never leaves your machine:
- Your settings (appearance, safety, visualization thresholds), stored in macOS's standard preferences system.
- Favorite folders and scan history, stored in a local file in Application Support.
- Full Disk Access permission, which is granted and managed entirely by macOS — DiskMapper never sees or stores anything about that grant beyond what the system tells it.
DiskMapper never reads the contents of your files — only the names, sizes, dates, and folder structure it needs to map what's using space, and to identify safe-to-remove system junk.
