HVAC Tech collects no personal data. None. It is a fully offline calculator. Everything you do stays on your device.
Nothing. HVAC Tech does not collect, store, or transmit any personal information. There are no accounts, no logins, and no sign-up.
Calculations and saved jobs are stored locally on your iPhone only. They are never uploaded to us or anyone else. If you delete the app, that data is removed with it.
HVAC Tech makes no network requests for its functionality. There is no analytics, no advertising, no third-party SDKs, and no tracking of any kind.
HVAC Tech Pro is a one-time in-app purchase processed entirely by Apple. We never see or receive your payment details. Apple's handling of that transaction is governed by Apple's Privacy Policy.
HVAC Tech is safe for all ages because it collects no data whatsoever.
Any updates to this policy will be posted on this page.
