Statement on Thyroid Tracker and Privacy
Last Updated: 2026.07.21
Thyroid Tracker is provided by Chengdu Star Crown Technology Co., Ltd. (hereinafter referred to as "we" or "us") for the Thyroid Tracker application. This privacy statement is formulated by us for processing your personal information.
We attach great importance to your personal information and privacy protection, and will provide corresponding security protection measures for your personal information in accordance with legal requirements and industry mature security standards.
1. How We Collect and Use Your Personal Information
We only use your personal information when we have a legal basis to do so. In accordance with applicable laws, we may use your personal information based on your consent, necessity for performing/contracting with you, or compliance with legal obligations.
1.1 Health Information Recording Function
When you use related services, we process necessary information to fulfill our contractual obligations. If you do not provide relevant information, it will affect your ability to use related functions/services of this app.
For the health information recording function, after obtaining your consent, the app will archive the following data that you voluntarily record:
- Examination indicators
- Exercise information
- Heart rate
- Blood pressure
- Other health information
We will not collect or share any of your personal privacy. If necessary, only anonymized indicator data is recorded.
2. Device Permissions
2.1 Permission List
| Permission | Purpose | Platform |
|---|---|---|
| Camera | Take photos of paper examination reports you need to upload | All |
| Media | Upload examination photos or screenshots you select | All |
| Storage | Store exported health charts | All |
| Network | Only when needed: - Register and login - Sync and backup data | All |
| Local Notification | Send medication or health reminders to your notification bar as local notifications | All |
| Boot Completed Broadcast Receiver | We use the 'boot completed' permission to ensure that after your device restarts, you can still receive your set reminders (such as to-do reminders/alarms) on time, preventing your reminder tasks from being lost. We will not use this permission to wake up the app for other operations without authorization. | Android only |
2.2 Special Permission Explanations
2.2.1 Special Explanation for Boot Completed Broadcast Receiver Permission
To ensure the reliability of health reminder functions, when you set medication or health reminders, the app will "register" the reminder into the system when your device restarts (by listening for system boot broadcasts), automatically restoring the reminder service. This process is completed locally only and does not collect any personal data.
Example: We set a medication reminder for 8 AM every morning, but the phone automatically restarts in the middle of the night. Without RECEIVE_BOOT_COMPLETED permission, the reminder won't ring. With it, the app can re-"register" the reminder into the system after boot, ensuring the reminder triggers normally.
2.2.2 Special Explanation for Local Notification Permission
When you set medication or health reminders, the app will register the set reminders into the system, and will remind you at the time point you set (by sending local notifications). This process is completed and notified locally only, does not involve network operations, and does not collect any personal data.
3. Third-Party SDKs
To provide you with some features/services, we have integrated software development kits (SDKs) or similar applications from partners. We conduct strict security checks on SDKs or similar applications and require partners to take strict measures to protect your personal data.
When new service requirements and business function changes arise, we may adjust the third-party SDKs we integrate and promptly disclose the latest information about third-party SDK integrations in this statement. Please note that third-party SDKs may have some changes in data types due to version upgrades, policy adjustments, etc. Please refer to their officially published explanations.
