# MR Physics, Chemistry and Biology Experiment — Observing the Structure of Chicken Eggs Privacy Policy

 

This privacy policy applies to the application "MR Physics, Chemistry and Biology Experiment — Observing the Structure of Chicken Eggs" (hereinafter referred to as "the Application") developed and published by Shenyang Jinran Technology Co., Ltd. (hereinafter referred to as "we"). We value the protection of user privacy and will collect, use, store, and share your personal information in accordance with this privacy policy. Please read this privacy policy carefully before using the Application to understand how we process your personal information.

1. Personal Information We Collect

1. Basic Information When you use this Application, we will not actively collect personal identity information such as your name, ID number, etc., in the traditional sense. However, in order to provide you with services and continuously optimize your application experience, we will collect the following information related to your use of the Application: 1. Device information: We collect information about your Pico device model (such as Pico4U), system version, device ID, etc., to ensure that the Application is compatible with your device and to provide you with stable service. Collecting this information helps us troubleshoot device-related technical issues and optimize application performance. 2. Sensor data: This Application uses the PICO Unity Integration SDK and collects your headset position, head and hand movement trajectories, spatial positioning data, etc., through the device's sensors (including but not limited to gyroscope, accelerometer, magnetometer, etc.). This data is used to implement spatial positioning and gesture interaction functions in MR scenarios, such as grabbing virtual experimental equipment, moving and operating them in experiments, all of which rely on this data. 3. Camera data: When you use the MR function of this Application, we will use the device's camera to capture real-time environmental images. The purpose is to overlay and merge virtual experimental models (such as virtual chicken egg structures) with the real environment to create an immersive experimental experience for you. 4. Usage logs: We record relevant log information about your use of the Application, including when you start and close the application, which functional modules you use, operation steps, etc. This information helps us analyze how the application is being used and optimize its functionality and performance.
2. Methods of Collecting Information 1. We collect the above information through your active operation of the Application and the automated means of interaction between the Application and Pico devices. 2. We only collect relevant information during your use of the Application, and will delete the relevant information within a reasonable period after you stop using the Application or cancel your account, unless otherwise stipulated by laws and regulations.

2. Permission Acquisition and Use

1. Camera Permission We obtain camera permission to capture real-time environmental images and achieve the fusion of virtual models with the real environment in MR experimental scenarios. You can turn off camera permission in device settings at any time. After turning it off, the normal use of MR functions may be affected, but it will not affect the use of other basic functions of the application.
2. Sensor Permission Obtaining sensor permission is to track the movement trajectories of the headset and hands, enabling precise spatial positioning and gesture interaction. If you turn off sensor permissions, you will not be able to perform normal gesture operations in MR experiments, such as grabbing and moving experimental equipment.

3. Use of Personal Information

1. Providing Services We use the personal information collected to provide you with the services of the "MR Physics, Chemistry and Biology Experiment — Observing the Structure of Chicken Eggs" application, including but not limited to: 1. Ensuring the application runs normally on your device and optimizing compatibility based on device information. 2. Implementing the interactive functions of MR experiments based on sensor and camera data, allowing you to perform experimental operations in a virtual environment. 3. Understanding how you use the application's functions through analyzing usage logs, and improving the application's functionality and performance.
2. Security Guarantee We will use personal information to prevent, detect, investigate, and handle potential security issues, including but not limited to preventing fraud, abuse, infringement, and ensuring the security of the application and users.

4. Sharing, Transfer, and Public Disclosure of Personal Information

1. Sharing We will not share your personal information with any third party, except: 1. With your explicit consent. 2. When providing a certain service jointly with partners, and such partners are bound by confidentiality agreements. For example, we use the PICO Unity Integration SDK, and the provider of this SDK may access some information related to device interaction, but only the necessary information required for implementing application functions, and they must comply with strict confidentiality obligations.
2. Transfer We will not transfer your personal information to any third party unless we obtain your explicit consent or as otherwise provided by laws and regulations.
3. Public Disclosure We will not publicly disclose your personal information unless we obtain your explicit consent, or as required by laws and regulations, when necessary to disclose to relevant regulatory authorities, judicial authorities, etc.

5. Cross-border Data Transfer If cross-border transfer is involved, a data export assessment needs to be initiated.
6. Protection of Minors The target user group of this Application is not limited. If we discover that the personal information collected belongs to minors (under 18 years of age), we will delete the relevant information as soon as possible after confirmation, unless otherwise stipulated by laws and regulations. If we subsequently provide services to minors, we will establish a parental consent mechanism, obtain the express consent of their parents or legal guardians before collecting personal information of minors, and take special measures to protect the personal information security of minors. If you are the guardian of a minor and find that the minor is using this Application and generating personal information that is being collected, you can contact us at windymeteor@163.com, and we will handle it promptly. VII. Updates to the Privacy Policy We may update this privacy policy due to changes in laws and regulations, business development, or adjustments to application functions. The updated privacy policy will be published within the Application or on our official website, and you will be notified in an appropriate manner (such as in-app pop-up notifications). If you continue to use the Application after the privacy policy is updated, you are deemed to have agreed to the content of the updated privacy policy.
7. Contact Us If you have any questions, comments, or suggestions regarding this privacy policy, or if you wish to exercise your related rights, you can contact us through the following means:
