Primary Care ("we," "our," or "the app") is a personal health companion for iOS. This Privacy Policy explains what data we collect, how it is used, and how it is protected.
When you sign in with Apple, we receive your name and email address (or an Apple relay address, if you choose to hide your email). This information is stored locally on your device.
With your permission, the app reads health metrics from Apple HealthKit, including:
If you connect a Fitbit account, similar health metrics are accessed via OAuth with your explicit consent.
Medications you add and dose records you log are stored locally on your device.
You may upload photos or PDFs of lab reports for AI-powered analysis. These are processed by our AI provider (see Section 3) and are not stored on our servers.
Conversations with the AI assistant are stored locally on your device.
Primary Care does not have a backend database. All personal data — health metrics, medications, dose records, lab results, chat history, and profile information — is stored locally on your device using encrypted storage (Expo SecureStore, backed by the iOS Keychain).
We do not have access to your data. Deleting the app deletes all of your data permanently.
The app interacts with the following third-party services:
When you use the AI assistant or upload lab reports, your health context and questions are sent to Anthropic's Claude API for processing. Anthropic processes this data according to their privacy policy. Primary Care does not store this data on any server.
Authentication is handled by Apple. We receive only the information you choose to share (name and email). Apple's privacy policy governs this data.
If you choose to connect Fitbit, health data is accessed via OAuth with your explicit consent. You can revoke access at any time through your Fitbit account settings at fitbit.com/settings.
We use PostHog for anonymous behavioral analytics to understand how the app is used (e.g., screen views, feature usage). No health data values, medication information, or personal health details are ever sent to PostHog.
We use Sentry to collect crash reports and error traces so we can fix bugs. No health data values or personal health information are included in crash reports.
All personal data is stored on your device only. We do not retain any health data, medication records, or chat history on servers. Deleting the Primary Care app from your device permanently deletes all of your data.
Primary Care is not intended for use by children under the age of 13. We do not knowingly collect data from children under 13. If you believe a child under 13 has used the app, please contact us and we will assist with any concerns.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the app after changes constitutes acceptance.
