Privacy Policy — HVAC Load Calc

Last updated: July 9, 2026

HVAC Load Calc ("the App") is operated by Vladimir Lukashov ("we", "us"). This policy explains how the App handles your information. The short version: your inputs stay on your device.

Your calculations stay on your device

• The App works on your device and offline. It has no accounts and no login.
• The house dimensions, insulation, and other load inputs you enter are used locally on your device only. We do not collect, see, or transmit them.
• We do not collect your name, email, location, or any personal or usage data.
• We do not use advertising or tracking of any kind.

Purchases

The App offers an auto-renewing subscription. Payment is processed by Apple through the App Store; we never see your payment details. To validate purchases the App uses RevenueCat, which receives an anonymous purchase receipt and a random identifier — never your identity. See RevenueCat's privacy policy.

Children

The App collects no data and is rated 4+.

Changes

We may update this policy; changes are reflected by the "Last updated" date above.
