Privacy Policy

Last updated: July 28, 2026

ClearBreath ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application ClearBreath (the "App").

1. Information We Collect

1.1 Information You Provide

  • Account Information: You can use the App with an anonymous account. If you choose to link your account through Apple Sign-In or Google Sign-In, we collect your email address and authentication identifiers.
  • Smoking Profile: Information about your smoking habits, including cigarettes per day, pack price, smoking duration, and quit date.
  • Health Data: Mood check-ins, craving levels, and relapse logs that you voluntarily submit.

1.2 Information Collected Automatically

  • Usage Data: App interactions and feature usage, collected via Firebase Analytics. We log the fact that a feature was used — not the health-related content of your entries.
  • Diagnostic Data: Crash reports and error logs, collected via Firebase Crashlytics.
  • Device Information: Device type, operating system version, and app version.

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve the App's functionality
  • Track your quit-smoking progress and health recovery timeline
  • Generate personalized quit plans and recommendations
  • Calculate achievements, streaks, and money saved
  • Send notifications and reminders (with your permission)
  • Analyze usage patterns to improve the App

3. Data Storage and Security

Your data is stored securely using the following services:

  • Firebase Authentication: Managed by Google, handles secure sign-in.
  • Firebase Firestore: Cloud database for syncing your data across devices. Data is encrypted in transit and at rest.
  • Firebase Analytics: Usage statistics that help us improve the App.
  • Firebase Crashlytics: Crash reporting and diagnostics.

4. Data Sharing

We do not sell, rent, or trade your personal information. We may share data only in these circumstances:

  • Service Providers: With Google (Firebase — authentication, database, analytics, crash reporting) and Apple (App Store purchases and subscription management) to operate the App, under strict data processing agreements.
  • Legal Requirements: If required by law, regulation, or legal process.
  • Safety: To protect the rights, safety, or property of our users or the public.

5. Your Rights

You have the right to:

  • Access: Request a copy of your personal data.
  • Correction: Update or correct inaccurate information.
  • Deletion: Delete your account and all associated data directly in the App (Profile → Delete Account), or by contacting us.
  • Export: Request a copy of your data in a portable format.
  • Opt-out: Disable notifications at any time in your device settings.

To exercise these rights, contact us at support@clearbreath.app.

6. Data Retention

We retain your data for as long as your account is active. When you delete your account:

  • Your account data is deleted when the in-app deletion process completes. If you request deletion by email, we complete it within 30 days.
  • Limited records may be retained only where required by law.
  • Anonymized, aggregated analytics data that can no longer be associated with your account may be retained for service improvement.

7. Children's Privacy

ClearBreath is not intended for use by anyone under the age of 13. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete it immediately.

8. Third-Party Services

The App may contain links to third-party websites or services (such as scientific research references). We are not responsible for the privacy practices of these external sites.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes through the App or via email. Your continued use of the App after changes constitutes acceptance of the updated policy.
