HVAC Calculator ("the App") is designed with your privacy in mind. We do not collect, store, transmit, or share any personal data. All calculations and saved data stay on your device.
This Privacy Policy explains what information the App handles and how. By using the App, you agree to this policy.
We do not collect, request, or have access to:
The App does not contain accounts, sign-in, or user registration.
Any data you create in the App — such as calculation inputs, results, projects, or saved entries — is stored locally on your device using Apple's on-device storage (SwiftData). This data:
If you have iCloud backup enabled on your device, your App data may be included in your personal iCloud backup. This is controlled entirely by you through your device settings and Apple's iCloud service, governed by Apple's Privacy Policy.
The App offers an optional one-time or subscription purchase to unlock Pro features. All purchases are processed by Apple through the App Store using Apple's in-app purchase system. We do not receive or store your payment details, credit card information, or Apple ID.
Purchase and restore-purchase information is handled by Apple and governed by Apple's privacy terms. We only receive anonymized, aggregated sales information from Apple, which does not identify you personally.
The App does not integrate third-party advertising, analytics, or tracking SDKs.
The only third party involved is Apple, which operates the App Store and the in-app purchase system. Apple's handling of your information is governed by Apple's own privacy policy.
The App does not knowingly collect any personal information from anyone, including children under the age of 13 (or the equivalent minimum age in your jurisdiction). Since no personal data is collected, the App is safe for users of all ages.
Because your data stays on your device and is not transmitted to us, the security of your data is protected by your device's built-in security features (such as device passcode and Apple's data protection). We recommend keeping your device and iOS up to date.
Since we do not collect or store any personal data on our servers, there is no personal data for us to access, correct, or delete. You remain in full control of all App data on your device and can delete it at any time by removing the data within the App or by uninstalling the App.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the App after changes are posted constitutes acceptance of the revised policy.
