Privacy Policy

Changsha Youlong Robot Co., Ltd. (hereinafter referred to as "we," "us," or "Maddox") understands the importance of your personal information. We are committed to protecting your personal data in compliance with applicable laws and regulations. This Privacy Policy (hereinafter "this Policy") explains how we collect, use, store, and safeguard your information when you use the Maddox Tech app (hereinafter "the App").

1. Information Collection

We do not collect any personal information. Maddox Tech serves as a control center for Maddox smart exoskeleton robot devices, and all data processing is performed locally on your device. We do not collect, upload, or store any of your personal data through the App.

Specifically:

• We do not require you to create an account or provide any personally identifiable information (such as name, email address, or phone number);
• We do not collect your location, contacts, photo library, or any other device permission-related data;
• We do not use any third-party analytics tools or advertising tracking technologies;
• Device-level training data is stored exclusively on your phone locally and is never uploaded to any server.

2. Local Data Processing

During normal operation, the App may create and store the following types of data locally on your device:

• Training Records: Including training duration, step count, motion mode, joint range of motion, and other rehabilitation data, used solely to generate your personal rehab reports;
• Device Connection Records: Including information about previously connected Maddox exoskeleton devices, used for quick reconnection and status management;
• App Preferences: Including language selection, notification preferences, and other configuration settings.

All of the above data is stored exclusively on your device locally. We do not collect, upload, or access this data in any way.

3. Information Sharing and Disclosure

Since we do not collect any personal information, there is no sharing or disclosure of personal data. We affirm that:

• We will not sell, trade, or transfer your personal information to any third party;
• We will not use your data for any commercial purposes;
• We will not respond to any external requests for user data, as we do not possess such data.

4. Information Security

Although we do not collect personal information, we take the security of your locally stored data seriously. We employ the following measures:

• The App uses iOS system-standard data isolation mechanisms, ensuring app data cannot be accessed by other applications;
• The App contains no network data transmission functionality (except for app update checks), minimizing data exposure risk;
• You can completely erase all locally stored data at any time by deleting the App from your device.

5. Children's Privacy

The App is rated 4+ and is suitable for users of all ages. Since we do not collect any personal information, there is no special collection or processing of children's data. If you are a parent or guardian and have questions about your child's information, please contact us using the details below.

6. Updates to This Privacy Policy

We reserve the right to update this Privacy Policy from time to time. When changes are made, we will notify you through appropriate means within the App. We encourage you to review this Privacy Policy periodically to stay informed about our privacy practices.
