Privacy Policy

Caesura for macOS, iOS, and Apple Watch — Effective March 6, 2026

What Caesura Does

Caesura is a personal health visualization app. The Apple Watch app collects health data from HealthKit. The macOS and iOS apps display that data as a living garden that reflects your wellbeing.

Data We Collect

Caesura accesses the following data, only with your explicit permission:

• HealthKit data — heart rate, step count, blood glucose, insulin delivery, sleep analysis, blood oxygen, respiratory rate, active energy, stand time, VO2 max, walking metrics, and related health samples. This data is read from HealthKit on your Apple Watch and iPhone.
• Account identifier — if you choose to sign in, a unique user ID is created to link your devices. No name, email, or personal information is required.

How Your Data Is Used

• Health data is used solely to generate your personal wellness visualization and health insights within the app.
• If you sign in, health data is synced to a secure database (Supabase) so your macOS and iOS apps can display data collected by your Apple Watch.
• If you do not sign in, the app operates in standalone mode and no data leaves your device.

Data We Do NOT Collect

• We do not collect your name, email address, phone number, or location.
• We do not use analytics, tracking, or advertising frameworks.
• We do not sell, share, or monetize your health data in any way.
• We do not access Apple Health Records (clinical data).

Data Storage and Security

Synced health data is stored in Supabase, a SOC 2 compliant cloud database with row-level security. Data is encrypted in transit (TLS) and at rest. Only your authenticated devices can access your data.

Data Retention and Deletion

You can delete your account and all associated health data at any time from within the app. Upon deletion, all synced data is permanently removed from our servers within 30 days.

Third-Party Services

Caesura uses Supabase for optional data synchronization between your devices. No other third-party services receive your data. Supabase's privacy policy is available at supabase.com/privacy.

Children's Privacy

Caesura is not directed at children under 12. We do not knowingly collect data from children.
