Privacy Policy

1. Information We Collect

When you create an account, we collect:

• Email address — used for login and account recovery
• Name — used for display purposes within the application
• Password — stored only as a salted, one-way hash (PBKDF2); we never store or have access to your plaintext password
• Usage data — basic information about how you interact with the service (features used, timestamps, error logs)

2. Case Data Processing

When you upload a case for analysis, the case text is sent to third-party AI providers for processing. Our privacy parser automatically strips personally identifiable information before it is transmitted to any AI service. This includes names, dates of birth, addresses, phone numbers, Social Security numbers, email addresses, medical record numbers, and other common personal identifiers.

During analysis, case text is processed in memory only. We do not retain raw case data for training, analytics, or any other purpose. If you do not save your analysis, all case data is discarded when your session ends. You are also welcome to upload case files that have already been de-identified.

3. Saved Analyses

HomeoBrain never asks for or stores patient names. If you choose to save an analysis, the results (extracted observations, rubrics, and remedy scores) are stored in our database and associated with your account — not with any patient identity. We strongly recommend using anonymized labels (e.g., "Case #42" or "Spring 2026 Follow-up") rather than patient names.

You have full control over saved data: you can view, manage, and permanently delete any saved analysis at any time from within the application. Deletion is immediate and irreversible.

4. Cookies

HomeoBrain uses a single session cookie to keep you logged in. This cookie is essential for the application to function and expires after 30 days of inactivity.

We do not use:

• Tracking cookies
• Analytics cookies
• Third-party advertising cookies
• Any form of cross-site tracking

5. Payment Processing

All payment processing is handled by Stripe. When you subscribe or make a payment, your card details are entered directly into Stripe's secure payment form. We never see, receive, or store your credit card number, CVV, or full card details. We only receive a confirmation of payment status and a truncated card identifier (e.g., "Visa ending in 4242") from Stripe for your records.

6. Third-Party Services

HomeoBrain relies on the following third-party services:

• Google Cloud — hosting and infrastructure
• Stripe — payment processing
• Anthropic (Claude) — primary AI provider for case essence extraction, remedy matching, clinical chat, and all pipeline analysis stages
• Google AI (Gemini) — secondary/fallback provider, used only when the primary provider is unavailable

Each of these services operates under its own privacy policy. Case data sent to AI providers is used solely for generating your analysis results and is subject to each provider's data handling terms. The vast majority of case processing is handled by Anthropic's Claude models.

7. Data Retention

• Account data (email, name, hashed password) is retained until you delete your account
• Saved analyses are retained until you delete them or delete your account
• Usage logs (anonymized) are retained for 90 days and then automatically purged
• Case text is processed in memory only and not retained beyond your active session (unless you explicitly save the analysis)

8. Your Rights

You have the right to:

• Delete your account — removes all associated data, including saved analyses
• Export your data — request a copy of your stored data
• Modify your data — update your name, email, or password

To exercise any of these rights, you can use the in-app settings or contact us.

9. Children's Privacy

HomeoBrain is not intended for use by individuals under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will promptly delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically to stay informed about how we handle your data.
