Privacy Policy

Effective Date: July 2026

Synapse is a personal health tracking application designed to help you manage your health on your terms. Your privacy is sacred—and that's why Synapse is built to be local-first, private, and fully under your control.

Our Core Promise

Your health data belongs to you.

Synapse does not sell, share, or use your data for advertising or profiling. Your data is stored on your device and, if you choose, securely backed up to your private iCloud.

1. What Information Do You Provide?

When you use Synapse, you may choose to enter:

• Your name and basic profile information (e.g., age)
• Health conditions and allergies
• Medication information and dosages
• Appointments and provider details
• Daily health logs (symptoms, mood, energy, sleep)
• Cycle tracking data (flow, symptoms, notes)
• Emergency contact information
• Any other health-related information you choose to track

You control what you enter. No health data is required beyond what you choose to log.
