Privacy Policy

Emerald is designed with a "Local First" architecture. Whenever possible, your sensitive health data (including cycle tracking, symptoms, and journal entries) is stored directly on your device using encrypted local storage. We do not monetize, sell, or aggregate your personal health data for advertising purposes.

We collect only the minimum information necessary to provide our services:

• Account Information: Name, email address, and encrypted password for authentication.
• Health Metrics: Data you explicitly log, such as cycle dates, mood, and symptoms.
• Usage Data: Anonymous, aggregated telemetry to help us improve app performance (e.g., crash reports).

All data transmitted between your device and our servers (for backup or sync features) is encrypted using industry-standard TLS 1.3 protocols. Data at rest is encrypted using AES-256 encryption. We employ strict access controls, ensuring that no unauthorized personnel can access your personal information.

4. Third-Party Services

We do not share your identifiable data with third parties for marketing. We may use trusted infrastructure providers (like secure cloud hosting) solely to operate the service. These providers are bound by strict data processing agreements to protect your privacy.

5. Your Rights

You maintain full ownership of your data. You have the right to:

• Export your data in a portable format.
• Delete your account and all associated data permanently.
• Opt-out of any optional data collection features.
