2. Information We Collect
2.1 Account Information
If you create an account, we collect your email address and a password (stored in hashed form). Your name is optional but may be collected if provided during registration. This data is stored securely in our database and is used solely to authenticate you and manage your subscription.
2.2 Subscription & Purchase Data
We use RevenueCat to manage in-app subscriptions and purchases. RevenueCat may collect your device identifier, purchase history, and subscription status.

2.3 App Usage & Analytics
We collect anonymised analytics data about how you use the app — including which screens you visit, how long you spend in the app, and general usage patterns. This data is collected via our internal analytics system. It cannot identify you personally and is used purely to improve the app experience.
2.4 Device & Technical Data
We may collect technical information such as your device type, operating system version, app version, and crash reports. Crash and error reporting is handled by Sentry (see Third-Party Services). This data helps us fix bugs and ensure app stability.

If you use the Formula Builder or Ask Herbert features, the content of your formulas and chat messages may be stored locally on your device and/or transmitted to our servers to generate AI responses. We do not sell or share this content with third parties.
2.6 No Health Data Sold or Shared
We do not sell, rent, or share your personal data or any health-related queries with advertisers or data brokers. Any wellness content you interact with in the app remains private.
