1. Information Collection
WeldGauge does not collect, store, or transmit any personal information, usage data, analytics, or device identifiers. The app runs entirely on your device and never contacts external servers.
2. Use of Information
Because no data is collected, no data is used, processed, shared, or sold to any third parties.
3. Camera & Photo Library
WeldGauge uses the device camera and photo library solely to capture and import weld images for on-device measurement. Photos are stored only in the app's local sandbox or the system photo library at your discretion. No images are uploaded, transmitted, or shared with any server or third party.
4. Third-Party Services
The app does not integrate any third-party SDKs, advertising frameworks, or analytics services. There are no in-app purchases.
5. Data Security
All image processing, edge detection, calibration, and weld measurement calculations occur entirely on your device. Measurement projects and reports are stored locally using SwiftData and are never synced to any cloud service.
6. Changes to This Policy
If the app's functionality changes in a way that affects privacy, this page will be updated with the new policy and an effective date.
7. Contact
