Privacy Policy

Effective May 21, 2026

Chiari Companion ("the app") is built as a private, local-first journal for people living with Chiari malformation and the people who care for them. This policy explains what data the app handles, where it stays, and what choices you have.

1. Information you enter

The app stores only the information you choose to enter, including:

• Daily check-ins (severity ratings for headache, neck pain, dizziness, fatigue, brain fog)
• Headache episodes (severity, duration, triggers, position, pain locations, notes)
• Symptom logs and custom symptom names
• Medication names, dosages, schedules, and dose logs you record
• Medical records you enter (titles, dates, facility, key notes, attached PDFs or photos)
• Surgery timeline entries
• Appointment notes and questions
• Cognitive check (brain-fog quiz) results
• Your first name (used only inside the app for greetings)

2. Where your data lives

Your journal is stored on your device using Apple's SwiftData framework and your device's secure file storage. iCloud backup may include this data only if you have iCloud backup turned on in iOS Settings, and in that case Apple handles the encryption per Apple's terms.

The app does not transmit your journal to us. We do not operate a backend server that stores it.

3. Permissions the app asks for

Apple Health (HealthKit)

If you grant access, the app reads sleep, blood oxygen, resting heart rate, walking steadiness, and selected symptom data from Apple Health to display alongside your own logs. This data stays on your device and is never sent off-device by the app. You can revoke access any time in iOS Settings → Privacy & Security → Health.

Location (when in use)

If you grant access, the app requests your approximate location no more than once per day to query Apple WeatherKit for local barometric pressure. The pressure reading is stored on your device. Your location coordinates are not stored and are not sent to us.

Notifications

Used only for medication reminders and a daily check-in nudge if you enable them. Notification content stays on your device.

Camera & Photo Library

Used only when you choose to attach a photo of an MRI report or clinic note to your records. Attached files are stored locally on your device.

Face ID / Touch ID

If you enable biometric lock, authentication is performed by iOS. The app never receives or stores your biometric data.

4. Apple WeatherKit

When the app fetches barometric pressure, it sends an approximate location to Apple's WeatherKit service. Apple's privacy policy governs that request: apple.com/legal/privacy/data/en/weather.

5. Purchases (RevenueCat & App Store)

Optional Pro features are sold through the Apple App Store. Apple processes the payment. We use RevenueCat to verify your subscription status. RevenueCat may receive an anonymous user identifier and your purchase status. RevenueCat's privacy policy: revenuecat.com/privacy. We do not receive your name, email, or payment details from Apple or RevenueCat.

6. Analytics & tracking

The app does not include third-party analytics SDKs, advertising SDKs, or trackers. We do not collect usage telemetry about which screens you visit.

7. Children

The app is not directed to children under 13. We do not knowingly collect personal information from children.

8. Sharing & exports

You can generate a visit summary (PDF) from your own logs. The summary is created on your device. Any sharing of that PDF — by email, AirDrop, print, or other means — is initiated by you and uses the system share sheet. We do not receive a copy.

9. Deleting your data

Settings → Delete Everything removes all journal entries and attached files from your device. Uninstalling the app also removes its on-device data (any iCloud backup copies are subject to Apple's controls in iOS Settings).

10. Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected in the "Effective" date at the top.
