HVAC Charge Pro1. Scope & contact
MUEN Apps provides HVAC Charge Pro and this marketing and support website. For privacy questions, contact muen@muenapps.com.
2. Calculations & saved jobs
No user account is required. Core calculations run locally on your device. Saved jobs remain on your device; the app does not send them to a MUEN Apps job database. Your device’s backup and operating-system settings may affect how on-device app data is backed up or removed.
Keep any job information you choose to enter limited to what you need. You control the records stored on your device.
3. Advertising, analytics & AI
The app has no advertising, advertising tracking, third-party analytics SDK, or third-party AI service. This website adds no analytics SDKs, tracking pixels, advertising tags, or tracking cookies.
4. Purchases & subscriptions
Apple StoreKit handles purchase and subscription processing and status. The app uses purchase or subscription status to determine access to paid features. MUEN Apps does not receive your payment card details through StoreKit.
Apple may process purchase, subscription, account, and related information under its own terms and privacy practices. See Apple’s Privacy Policy. Apple controls its own processing of that information.
5. Support & voluntary diagnostic sharing
If you email support, MUEN Apps receives the email address, message, and attachments you choose to send. We use these to respond, investigate issues, and maintain relevant support records.
Diagnostic sharing through Report Calculation Issue is user-triggered. Review the information before choosing to share it. Calculation inputs and technical details you include may help investigate a reported issue. Diagnostic information is not automatically sent merely because you perform a calculation.
Do not share passwords, authentication secrets, payment card data, unnecessary personal information, or sensitive customer or job information.
6. Device permissions
The current core functionality does not require access to Camera, Photos, Location, Contacts, or Microphone.
7. Website hosting
This static website is hosted on Firebase Hosting. Hosting infrastructure may process standard request information, such as IP address, requested page, browser information, and request time, to deliver and protect the website. This is separate from adding analytics or advertising tracking to the site. Google’s handling of information is described in its Privacy Policy.
8. Information handling & retention
Support information may be processed by the email and service infrastructure needed to receive and answer your message. We do not sell your personal information or use support messages for advertising tracking. Information may also be disclosed where required by law or necessary to protect legal rights and service security.
We retain support communications only as needed to address the request, maintain relevant support records, or meet legal obligations. No fixed retention period is promised. On-device job retention is controlled by your use of the app and your device settings.
We use reasonable safeguards for information we receive, but no transmission or storage method is completely secure.
9. Your choices & requests
You can use core calculations without an account and choose whether to contact support or share diagnostic details. Manage on-device records within the available app controls and your device settings.
To request access, correction, or deletion of personal information in support communications, email muen@muenapps.com. We will address requests in accordance with applicable law and may need to verify the request. We cannot retrieve local-only job records from your device. Contact Apple for information controlled by Apple.
10. Intended audience
HVAC Charge Pro is intended for HVAC technicians and field professionals, rather than children. We do not knowingly seek personal information from children. If you believe a child has sent personal information to support, contact us so we can address it.
11. Changes to this policy
We may update this policy when the product or relevant practices change. The updated policy and date will appear on this page. Material changes will be communicated as required by applicable law.
