Privacy Policy

Last updated: April 22, 2026

Herbal Vanguard ("we," "our," or "us") operates the Herbal Vanguard mobile application. This Privacy Policy explains how we collect, use, and protect your information when you use our app.

Information We Collect

We collect minimal data necessary to provide our services:

• Device Identifiers: We collect anonymous device IDs for rate-limiting our AI wellness assistant (HerbAI). These are not linked to your personal identity.
• Purchase History: When you subscribe to a paid plan (Starter, Pro, or Elite), purchase information is processed through Google Play Billing (or Apple In-App Purchase) and RevenueCat. We receive subscription status data to unlock features but do not store payment card details.
• AI Chat Messages: Messages sent to HerbAI are transmitted to our secure proxy server and forwarded to the Anthropic API for response generation. These messages are processed ephemerally and are not persistently stored on our servers.

Information We Do Not Collect

• Names, email addresses, or phone numbers
• Location data
• Photos or camera data
• Contacts or address books
• Browsing or search history
• Health data — diary entries are stored locally on your device only

How We Use Your Information

• App Functionality: Device IDs are used solely for rate limiting AI requests to ensure fair usage across all users.
• Subscription Management: Purchase data is shared with RevenueCat to verify your subscription status and unlock premium features.
• AI Responses: Chat messages are sent to the Anthropic API to generate wellness-related educational responses.

Data Storage & Security

All data transmitted between the app and our servers is encrypted in transit using HTTPS/TLS. Your wellness diary, supplement logs, and personal tracking data are stored locally on your device and are never transmitted to our servers.

Third-Party Services

• RevenueCat: Manages subscription billing and entitlements. See RevenueCat's Privacy Policy.
• Anthropic API: Processes AI chat requests. See Anthropic's Privacy Policy.
• Google Play Billing / Apple In-App Purchase: Handles payment processing for subscriptions.
• Amazon Associates: Affiliate links to Amazon products. Amazon's privacy policy applies when you visit their site.

Children's Privacy

Herbal Vanguard is not intended for use by children under 13. We do not knowingly collect information from children.

Your Rights

You may request deletion of any server-side data associated with your device by contacting privacy@herbalvanguard.com. Locally stored data can be deleted by clearing app data or uninstalling the app.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date above. Continued use of the app after changes constitutes acceptance of the updated policy.
