Privacy Policy

Last updated: February 23, 2026

Welcome to PureLung. We respect your privacy and are committed to protecting your personal data. This Privacy Policy outlines our practices regarding the collection, use, and disclosure of information when you use our mobile application (the "App").

1. Information We Collect

When you use our App, we may collect the following types of information:

Health and Fitness Data (Apple HealthKit): PureLung integrates with Apple’s HealthKit framework to provide comprehensive insights, such as heart rate changes and breathing capacity, related to your smoke-free journey. You have full control over what data is read from or written to HealthKit directly through the Apple Health app settings. We do not use this data for marketing or advertising purposes.
App Usage Data: We may collect anonymous data about your interactions with the app, such as session durations and feature engagement, to improve our services and user experience.
Crash Data: In the event of an app crash, anonymous diagnostic reports may be collected to help us identify and fix technical issues.

2. How We Use Your Information

We use the information we collect for the following purposes:

To provide, maintain, and improve the App's core functionality (e.g., tracking smoke-free days, calculating money saved, and displaying health milestones).
To synchronize and process HealthKit data securely on your device, enhancing the personal accuracy of your health improvement timelines.
To communicate with you, including responding to support inquiries and sending essential app updates.
To analyze app performance and fix bugs.

3. HealthKit Data Privacy

Because PureLung handles sensitive health data through Apple HealthKit, we adhere to strict guidelines:

Data Security: HealthKit data is processed locally on your device or securely synced via your iCloud account. We do not store your HealthKit data on external servers.
No Third-Party Sharing: We will never sell, lease, or rent your HealthKit data to third parties. We do not use HealthKit data for advertising, marketing, or use-based data mining.
Consent: Reading and writing data to Apple Health requires your explicit authorization. You can revoke this access at any time through the iOS Settings or the Apple Health app.

4. Third-Party Services

The App may utilize third-party services (such as analytics or crash reporting tools) that may collect information used to identify you. These third-party service providers have their own Privacy Policies addressing how they use such information.

5. Security of Your Data

The security of your data is important to us. We strive to use commercially acceptable means to protect your personal information, but remember that no method of transmission over the Internet or method of electronic storage is 100% secure.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date at the top.
