Privacy Policy

Last updated: 2026-04-06

1. Introduction

Thank you for using Cervi Tracker. We respect your privacy and are committed to protecting any personal data you share with us. This policy explains what data we collect, how we use it, and your rights regarding your information.

2. Data We Collect

Cervi Tracker collects only the information necessary to provide its core tracking functionality:

• Account data: Your email address, used for authentication via Supabase.
• Medical tracking data: Information you enter into the app — including treatment events, blood test results, imaging study measurements, and clinical profile details (cancer type, stage, histology). This data is entered by you and stored to provide the tracking and reporting features of the app.
• Settings data: App preferences such as theme mode and language, stored locally on your device.

We do not collect location data, biometric data, or any information beyond what you explicitly enter into the app.

3. How We Use Your Data

Your data is used solely to provide the features of Cervi Tracker:

• To display your treatment timeline, blood trends, imaging dynamics, and cycle-based overview.
• To generate local PDF reports that you can share with your physician.
• We do not sell, rent, or share your personal or medical data with third parties.
• We do not use your data for advertising or profiling purposes.

4. Data Storage and Security

Your tracking data is stored securely using Supabase, a cloud backend provider with industry-standard security practices. PDF reports are generated locally on your device and are not transmitted to our servers.

We take appropriate technical measures to protect your data, but no method of electronic storage is 100% secure. We encourage you to use a strong password and keep your account credentials private.

5. Medical Data Disclaimer

Cervi Tracker is a personal tracking tool, not a medical device or clinical system. The data you enter is used only to display your personal tracking history. We do not analyze, interpret, or act on your medical data in any way. All clinical interpretation remains the sole responsibility of qualified healthcare professionals.

6. Data Deletion

You have full control over your data. You may delete your account and all associated information at any time from within the app (Settings → Delete Account). Upon deletion, your personal profile and all associated tracking records are permanently removed from our servers.

7. Children's Privacy

Cervi Tracker is intended for adult users managing their own health tracking. We do not knowingly collect data from children under the age specified by applicable local laws.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Continued use of the app after changes are published constitutes acceptance of the updated policy. We will update the "Last updated" date at the top of this page.
