NDT Helper ("the App") is developed and operated by Edison Iverbotor. This privacy policy explains how we collect, use, and protect your information when you use our mobile application.

Data We Collect

When you use NDT Helper, we may collect the following types of information:

• Account Information: When you sign in with Apple, we receive your name and email address (or a private relay address if you choose to hide your email). This is used solely for authentication and displaying your identity within the app.
• Inspection Data: Defect photos, project data, equipment records, diagrams, and raw data records that you create within the app. This data is created by you and belongs to you.
• Device Identifiers: Basic device identifiers used for authentication purposes through Firebase Authentication.

How We Use Your Data

• To provide and maintain the App's core functionality
• To enable cloud sync and backup of your inspection data
• To enable team collaboration features when you choose to share projects
• To authenticate your identity and secure your account

Data Storage

• Local Storage: All inspection data is stored locally on your device by default. The app works fully offline.
• Cloud Storage: When you use cloud features (collaboration, cloud share), your data is stored in Google Firebase services (Firestore and Cloud Storage), hosted in the United States. Data is transmitted using industry-standard encryption (TLS/SSL).

Data Sharing

We do not sell, trade, or rent your personal information to third parties. Your inspection data is only shared with collaborators you explicitly invite via share codes. When you generate a share code, only users with that specific code can access the shared project.

Third-Party Services

The App uses the following third-party services:

• Firebase Authentication: For secure sign-in with Apple. Firebase Privacy Policy
• Firebase Firestore: For cloud data storage and sync.
• Firebase Cloud Storage: For storing photos and images.

These services are operated by Google and are subject to Google's privacy policy.

Data Retention

• Local data remains on your device until you delete it or remove the app.
• Cloud data associated with shared projects is retained as long as the project exists.
• You may delete your account and associated cloud data at any time by contacting us.
