Privacy Policy
Last Updated: December 2025
Overview
Ankora is a health tracking app that helps you understand your wellness data. We prioritize your privacy and process health data anonymously.
Key Principle: Your health data stays on your device in Apple HealthKit. When you use LLM-powered features, only anonymized data is used - never any data that can identify you.
1. What We Use
