Privacy Policy

Last updated: February 24, 2026

1. Introduction

CF Companion ("we", "our", or "the app") is a health tracking application designed for cystic fibrosis patients, caregivers, and family members. We are committed to protecting your privacy and handling your personal data responsibly. This privacy policy explains what information we collect, how we use it, and your rights regarding your data.

2. Information We Collect

We collect the following types of information:

Account Information: Email address and password (stored securely via Supabase Authentication).
Profile Information: Name, date of birth, user role (patient, caregiver, or family member), and patient relationships.
Health Data: Treatment logs, medication records, symptom entries, nutrition and hydration logs, airway clearance sessions, and other health-related information you choose to enter.
Usage Data: App interaction data to improve functionality and user experience.

3. How We Use Your Information

Your information is used to:

Provide and maintain the core app functionality (tracking, logging, reports).
Enable family member access to patient data (only when explicitly linked by the patient or caregiver).
Generate health reports for sharing with your medical care team.
Improve the app's features and user experience.
Process subscription payments (via Adapty — we do not store payment details).
Display advertisements to free-tier users (via Google AdMob).

4. Data Storage and Security

Your data is stored securely on Supabase servers with row-level security (RLS) policies ensuring that users can only access their own data and data explicitly shared with them. All data is transmitted over encrypted HTTPS connections. We implement industry-standard security measures to protect your information.

5. Data Sharing

We do not sell your personal data. Your health data is never shared with third parties for marketing purposes. Data is shared only in these circumstances:

Family Access: When you explicitly link family members to a patient profile, those family members can view (but not modify) health data.
Service Providers: We use Supabase (data hosting), Adapty (subscription management), and Google AdMob (advertising). These providers process data as necessary to deliver their services.
Legal Requirements: If required by law or legal process.

6. Advertising

Free-tier users may see advertisements served by Google AdMob. AdMob may collect device identifiers and usage data to serve relevant ads. You can opt out of personalized advertising through your device settings. Pro subscribers do not see advertisements.

7. Children's Privacy

CF Companion is not directed at children under 13. Caregivers and parents may use the app to track health data for minors under their care. In such cases, the caregiver is responsible for the data they enter. We do not knowingly collect personal information directly from children under 13.

8. Your Rights

You have the right to:

Access: View all personal data we hold about you within the app.
Export: Generate and download reports of your health data (PDF/CSV).
Delete: Permanently delete your account and all associated data through the app's account settings. This action is irreversible.
Rectify: Update or correct your personal information at any time.

9. Data Retention

Your data is retained for as long as your account is active. When you delete your account, all personal data and health records are permanently deleted from our servers. This deletion is irreversible and complies with GDPR requirements.

10. International Users

CF Companion is available in 10 languages and serves users worldwide. Your data may be processed in countries where our service providers operate. By using the app, you consent to the transfer and processing of your data in accordance with this policy.

11. Changes to This Policy

We may update this privacy policy from time to time. We will notify users of significant changes through the app or via email. Continued use of the app after changes constitutes acceptance of the updated policy.
