Privacy policy

LAST UPDATED · AUGUST 4, 2026

CheckMyMac is built to be run on machines you are inspecting — including machines you don't own yet. So the privacy rule is simple: the app looks at hardware and keeps what it sees on that Mac.

What the app reads

Hardware state only: battery health, port topology, sensor readings, model identifiers and system diagnostics logs. This data is used to render checks and reports on the Mac where the app runs.

What leaves the Mac

• Nothing, during diagnostics. All checks run locally and work fully offline.
• License activation contacts our payment provider (Lemon Squeezy) once, sending the license key and a device identifier — this is required to bind the license. No hardware report data is included.
• Update checks fetch a signed version feed from this website; update packages download from GitHub Releases. No personal data is sent.

What we never do

• No analytics, no tracking, no telemetry in the app.
• No fingerprint or biometric data is read, stored or transmitted — the Touch ID test counts sensor reactions, not fingerprints.
• PDF reports stay where you save them; we never see them.

This website

The site is static, sets no cookies and runs no analytics scripts. The app download is hosted on GitHub Releases, so GitHub’s privacy policy applies to the download request. Purchases are processed by Lemon Squeezy as merchant of record — their privacy policy applies to checkout.
