Privacy Policy

MingMing Team ("we," "us," or "our") operates the Electrician Field Pro mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. Please read this policy carefully. By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

We collect minimal information to operate and improve the App. The types of information we may collect include:

a. Information You Provide Voluntarily

• Support communications: If you contact us for support, we may collect your email address and any information you include in your message.
• Feedback: Any feedback, suggestions, or reviews you voluntarily submit.

b. Automatically Collected Information

• Usage data: We may collect anonymized, aggregated data about how you interact with the App (e.g., feature usage frequency) to improve performance and user experience.
• Device information: Non-identifiable technical data such as device model, operating system version, and app version, used for diagnostics and compatibility.
• Crash reports: If the App crashes, we may collect anonymized crash logs to fix bugs. These logs do not contain your calculation inputs or personal identifiers.

c. Calculation Data

All calculations, inputs, saved history, and favorites are stored locally on your device. We do not transmit, access, or store your calculation data on our servers. You have full control over this data and can delete it at any time by clearing the App's data or uninstalling the App.

2. How We Use Your Information

We use the limited information we collect for the following purposes:

• To provide, maintain, and improve the App's functionality.
• To respond to your support requests and feedback.
• To monitor usage trends and diagnose technical issues.
• To comply with legal obligations and enforce our terms.

3. Sharing and Disclosure

We do not sell, trade, or rent your personal information to third parties. We may share information only in the following limited circumstances:

• Service providers: Trusted third-party services that assist us in operating the App (e.g., analytics, crash reporting) under strict confidentiality agreements. These providers only receive anonymized data.
• Legal requirements: If required by law, regulation, or valid legal process, we may disclose information to comply with such obligations.
• Business transfers: In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you of any such change.

4. Data Security

We take reasonable measures to protect the information we collect. However, no method of electronic storage or transmission over the internet is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

Because core calculations are stored locally on your device, the security of that data depends on your device's security settings (e.g., passcode, encryption). We recommend keeping your device software updated and using device-level protections.

5. Children's Privacy

The App is not directed to individuals under the age of 13 (or the applicable age of consent in your jurisdiction). We do not knowingly collect personal information from children. If you become aware that a child has provided us with personal information, please contact us, and we will take steps to delete such information.

6. Third-Party Links and Services

The App may contain links to third-party websites or services (e.g., NEC references, manufacturer documentation). We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies before providing any information.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy within the App or on our website. Your continued use of the App after such changes constitutes your acceptance of the updated policy.
