AR Measure Pro - Privacy Policy

Effective Date: This Privacy Policy applies to AR Measure Pro (the "App") and explains how information is collected, used, and disclosed by the App.

1. Information We Collect

1.1 Information You Provide

The App does not require you to create an account or provide any personal information to use its core features. We do not collect your name, email address, phone number, or any other personally identifiable information unless you choose to contact us for support, in which case we will collect the information you provide (such as your email address and any details about your issue).

1.2 Information Collected Automatically

When you use the App, we may automatically collect certain information about your device and usage of the App. This information may include:

Device information: Such as your device model, operating system version, unique device identifiers (e.g., iOS identifier for advertising, if available), and network information.
Usage data: Information about how you use the App, including the features you use, the actions you take, and the time and duration of your sessions.
AR Measurement Data: The measurements you take using the App, including spatial data, point coordinates, and distance calculations. This data is stored locally on your device and is not transmitted to our servers.

1.3 Camera and Sensor Data

The App uses your device's camera and sensors (such as accelerometer, gyroscope, and magnetometer) to provide AR measurement functionality. Camera frames and sensor data are processed locally on your device to generate measurements and are not stored or transmitted outside of your device, except as necessary to save your measurement sessions locally on your device.

2. How We Use Your Information

We use the information we collect for the following purposes:

To provide and improve the App's functionality, including AR measurement features, session saving, and unit conversion.
To understand how users interact with the App, which helps us improve the user experience and develop new features.
To respond to your support requests and provide customer service.
To comply with applicable laws and regulations.

3. How We Share Your Information

We do not share, sell, rent, or trade your personal information with third parties for their marketing purposes. We may share information in the following limited circumstances:

With service providers who assist us in operating the App and providing our services, such as hosting services and analytics providers. These service providers are contractually obligated to protect your information and use it only for the purposes we specify.
When required by law, such as to comply with a subpoena or other legal process, or to protect our rights, property, or safety, or the rights, property, or safety of others.
In connection with a merger, acquisition, or sale of all or a portion of our assets, in which case your information would be transferred as part of the transaction.

4. Data Retention

We retain the information we collect for as long as necessary to provide the App's services and for legitimate business purposes, such as maintaining records, complying with legal obligations, and resolving disputes. If you contact us for support, we may retain the information you provide to respond to your inquiry and for related purposes.

AR measurement data and session information are stored locally on your device and will remain there until you delete the App or clear the App's data through your device settings.

5. Your Choices and Controls

You have several choices regarding the information collected by the App:

Camera Access: You can control whether the App has access to your device's camera through your device settings. Disabling camera access will prevent the App from providing AR measurement functionality.
Local Data: You can delete the App at any time, which will remove all locally stored data associated with the App from your device.
Advertising Identifiers: You can reset your device's advertising identifier or limit ad tracking through your device settings, which may affect the information collected for analytics purposes.

6. Security

We take reasonable measures to protect the information collected by the App from unauthorized access, use, or disclosure. However, no method of transmission over the internet or electronic storage is completely secure, so we cannot guarantee absolute security. The App processes and stores all measurement data locally on your device, which reduces the risk of data breaches compared to cloud-based storage.

7. Children's Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will take steps to delete such information.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you by updating the "Effective Date" at the top of this policy and, if possible, through the App or other communication channels. We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information.

9. Contact Us

If you have any questions or concerns about this Privacy Policy or the App's privacy practices, please contact us at: weiceyi2932@163.com

10. Offline Operation

AR Measure Pro is designed to operate completely offline. No camera frames, point-cloud data, measurement logs, or personal information leave your device during normal operation. All calculations and data processing occur locally on your device, ensuring your privacy is protected without requiring an internet connection.

11. Third-Party Services

The App may contain links to third-party websites or services. This Privacy Policy does not apply to such third-party services, and we are not responsible for their privacy practices. We encourage you to review the privacy policies of any third-party services you use.

12. Data Processing Location

Since all data processing occurs locally on your device, your information is processed in the country where your device is located. If you travel with your device, your information may be processed in the countries you visit.

13. Your Rights Under Data Protection Laws

Depending on your location, you may have certain rights under applicable data protection laws, such as the right to access, correct, or delete your personal information. To exercise these rights, please contact us at weiceyi2932@163.com. We will respond to your request in accordance with applicable law.

14. Cookies and Similar Technologies

The App does not use cookies or similar tracking technologies. All usage data is collected and stored locally on your device and is not shared with third parties unless required by law.

15. Subscription Information

When you purchase a subscription to AR Measure Pro, your payment is processed by Apple through the App Store. We do not collect or store your payment information.
