Thank you for choosing HealthHill: Blood Sugar & Blood Pressure (hereinafter referred to as "the App"). We understand the sensitivity of health data and always prioritize your privacy protection. This Privacy Policy aims to clearly and transparently explain to you how we collect, use, store, and protect your relevant information when you use the iOS version of the App.
We strictly comply with the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and the Apple App Store privacy guidelines, and are committed to providing you with a safe and reliable user experience. Please carefully read and understand this policy before using the App. If you continue to use the App, it indicates that you agree to our processing of your information in accordance with this policy.
1. Information We Collect and Collection Methods
To ensure the normal operation of the App's core functions, we only collect the minimum data necessary to provide services and do not collect any unrelated information.
1.1 Health-Related Data (Heart Rate Data)
- Collection Scope: The App may obtain heart rate data through two methods: ① With your authorization, accessing your device's built-in sensors (such as camera and flash) for real-time measurement; ② Heart rate records you manually enter (including historical heart rate data you actively record).
- Data Nature: This type of data belongs to sensitive health information and is only used to implement the core function of heart rate monitoring. It is stored only on your device locally throughout the entire process and will not be uploaded to our servers, cloud, or shared with us or any third parties in any form.
1.2 Non-Personally Identifiable Information (Device and App Technical Data)
- Collection Scope: To optimize app performance, fix potential vulnerabilities, and improve user experience, we may collect the following anonymized, non-personally identifiable technical data:
- Basic device information: Device model, iOS system version, device language settings, region (only accurate to country/region, not involving specific geographic location);
- App usage information: Installation version of the App, launch frequency, feature usage records (such as the number of times the "heart rate measurement" function is used);
- Performance and fault data: App crash logs, crash records, loading delays, and other performance statistics (all personally identifiable associated data has been removed).
- Collection Method: This type of data is automatically collected by the app in the background without requiring manual operation and does not affect your normal use.
2. How We Use Your Information
We use the collected information only for the following explicit purposes and do not use it beyond the necessary scope:
- To provide you with core heart rate monitoring services: Real-time measurement, calculation, and display of heart rate results, generation of locally stored heart rate data charts and historical change trends for your convenience in viewing your heart rate status;
- To optimize app performance and stability: By analyzing anonymized technical data, troubleshoot app faults, fix vulnerabilities, improve app operation smoothness, and optimize functional design;
- To ensure service compliance: Conduct necessary technical adaptations and compliance adjustments according to relevant laws and regulations and Apple App Store requirements to ensure that the App continues to meet usage standards.
3. Data Storage and Security Protection
3.1 Data Storage Methods
- All sensitive health data (including heart rate records and manually entered related information) is stored only on your iOS device locally, without cloud synchronization, remote backup, or server storage;
- Anonymized technical data (such as crash logs) is only temporarily stored when necessary and is automatically cleared regularly, not retained long-term.
3.2 Security Protection Measures
We employ industry-standard security technologies and protective measures to safeguard the data on your device:
- Data is stored in an encrypted manner within the App to prevent unauthorized access;
- Data access permissions are strictly limited, and only core functional modules of the App can call relevant data;
- Security mechanisms are continuously optimized to address potential security risks and ensure data is not tampered with, leaked, or lost.
4. Third-Party Services and Data Sharing
We promise not to share, sell, or rent your personal information or sensitive health data (including heart rate data) to any third party.
To achieve app performance analysis and fault troubleshooting, we may use strictly reviewed third-party tools (such as crash reporting tools and app statistics tools), but such tools can only collect anonymized, non-personally identifiable technical data (such as device model and crash logs). They cannot access or obtain any of your health information or personally identifiable information. The use of third-party tools strictly follows their own privacy policies, and we supervise their compliant processing of relevant data.
5. Your Rights and Data Control
You have complete control over all your data and can exercise the following rights at any time:
- Right to View Data: View all locally stored heart rate records and related data within the App at any time;
- Right to Complete Deletion: If you uninstall the App, all health data and usage records related to the App stored on your device will be completely cleared without residue;
- Right to Withdraw Authorization: If you have previously authorized the App to access device sensors, you can withdraw authorization through iOS system settings (Settings - Privacy & Security - Health/Camera/Flash). After withdrawal, the App will no longer be able to measure heart rate through sensors, but it will not affect your ability to manually enter data.
6. Updates and Notifications to Privacy Policy
We may revise this Privacy Policy from time to time based on updates to laws and regulations, adjustments to app functions, or optimization of privacy protection practices.
When this policy changes, we will update the "Effective Date" above. Please check regularly.
