Privacy Policy
This Privacy Policy describes how your personal information is collected, used, and shared when you use the Sizing application (the "App").
1. Information We Collect
When you use the App, we may collect the following types of information:
1.1 Information You Provide
We do not require you to create an account or provide any personal information to use the basic features of the App. However, if you choose to contact us for support or feedback, you may provide us with information such as your name and email address.
1.2 Information Collected Automatically
When you use the App, we may automatically collect certain information about your device, including:
- Device model and operating system version
- Unique device identifiers (such as IDFV)
- Camera usage data (only when using the measurement features)
- Usage data, such as features used and time spent in the App
1.3 Measurement Data
All measurement data created using the App is stored locally on your device. We do not collect, store, or have access to this measurement data unless you explicitly choose to share it with us (for example, when seeking technical support).
2. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the App
- Develop new features and functionality
- Understand how users interact with the App
- Respond to your support requests and feedback
- Prevent fraud and ensure the security of the App
3. Local Storage of Data
The App stores all measurement data locally on your device. This means:
- Your measurement data remains private and is not sent to our servers
- You have full control over your data
- Data may be lost if you uninstall the App or reset your device, unless you have backed up your device
4. Sharing Your Information
We do not share your personal information with third parties except in the following cases:
- With your explicit consent
- To comply with applicable laws, regulations, or legal requests
- To protect our rights, privacy, safety, or property, and that of our users
- With service providers who assist us in operating the App, under strict confidentiality agreements
5. Data Retention
Since all measurement data is stored locally on your device, we do not retain any measurement data. If you provide us with personal information (such as when contacting support), we will retain that information only for as long as necessary to fulfill the purposes for which it was collected, unless a longer retention period is required by law.
6. Your Rights
You have the right to:
- Access the personal information we hold about you
- Request correction of any inaccurate personal information
- Request deletion of your personal information
- Object to or restrict our processing of your personal information
To exercise these rights, please contact us at chicunceliang9749@163.com.
7. Security
We take reasonable measures to protect the information we collect 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.
8. 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 that information.
9. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the App and updating the "effective date" at the top of this policy. You are advised to review this Privacy Policy periodically for any changes.
