📋 2. Data We Collect

We collect the following categories of data:

2.1 Account Registration Data

When you create an account, we collect:

2.2 Calculation / Patient Data

When you use the calculators, the app can save:

• Patient name and optional MRN (if you choose to save a calculation)
• Gestational age, EDD, LMP, and calculation method
• Date and time of each saved calculation

2.3 Automatically Collected Data

We do not use analytics SDKs, advertising trackers, or usage profiling tools. Firebase may collect limited technical data (such as crash reports and app performance metrics) as described in Google's Firebase Privacy Policy.

⚙️ 3. How We Use Your Data

• To create and manage your user account
• To authenticate you securely across sessions
• To store your saved patient records and calculation history
• To display your name and clinic on PDF exports
• To maintain your app preferences (dark mode, Hijri display, font size, etc.)
• To respond to support requests you send us

We do not use your data for advertising, profiling, resale, or any purpose not listed above.

☁️ 4. Data Storage & Security

Your data is stored using Google Firebase services, including:

• Firebase Authentication — manages login credentials securely
• Cloud Firestore — stores your profile and saved patient records
• Firebase Storage — stores your profile photo (if uploaded)

All data is stored on Google's infrastructure with industry-standard encryption at rest and in transit (TLS). Access to your data is protected by Firebase Security Rules that restrict each user to their own records only.

Calculation history (last 100 entries) is stored locally on your device using SharedPreferences and is not transmitted to our servers unless you explicitly save a patient record.

🤝 5. Data Sharing

We do not sell, rent, trade, or share your personal data with any third parties for commercial purposes.

We may share data only in the following limited circumstances:

• Service providers: Google Firebase (data storage and authentication) — bound by Google's data processing terms
• Legal requirements: If required by law, court order, or governmental authority
• Safety: To prevent imminent harm or protect the rights and safety of users

⏳ 6. Data Retention

• Account data is retained for as long as your account is active
• Saved patient records are automatically deleted when gestational age exceeds 60 weeks, or when you delete them manually, or when you delete your account
• Calculation history (local) is limited to the last 100 entries and can be cleared at any time from the app
• Profile photos are stored until you delete them or delete your account

Upon account deletion, all associated data (profile, patient records, photos) is permanently removed from our servers within 30 days.

⚖️ 7. Your Rights

You have the following rights regarding your personal data:

• Access: View all data stored in your account via the My Account screen
• Correction: Update your profile information at any time
• Deletion: Delete individual patient records, clear your history, or delete your entire account from within the app
• Portability: Contact us to request an export of your data
• Objection: Contact us to raise concerns about how your data is processed

To exercise any of these rights, contact us at support@obicalc.com. We will respond within 30 days.

👶 8. Children's Privacy

ObiCalc is strictly intended for use by qualified healthcare professionals. It is not directed at, and should not be used by, anyone under the age of 18.

We do not knowingly collect personal information from anyone under 18. If you believe a minor has created an account, please contact us at support@obicalc.com and we will promptly delete the account and associated data.

Continued use of ObiCalc after a policy update constitutes acceptance of the revised policy.
