LIRIN (“we”, “our”, or “us”) is a wellness app developed by Madan Mohan Kumar Shanthakumar. This Privacy Policy explains how we collect, use, and protect your information when you use the LIRIN iOS app.
With your explicit consent, LIRIN reads the following data from Apple HealthKit:
This data is used solely to calculate your daily recovery score and generate personalised coaching insights. We never use HealthKit data for advertising or sell it to third parties.
When you create an account, we collect:
We collect basic usage information including:

LIRIN uses Claude, an AI made by Anthropic, to generate daily briefs and coaching responses. We send Anthropic anonymised, aggregated health metrics only — for example, “HRV: 52ms, sleep: 7.2h”. We never send your name, email address, or any directly identifiable information to Anthropic. See Anthropic’s Privacy Policy.
When you scan a meal photo, the image is sent to our server and to Anthropic’s API for calorie and nutrient analysis. Photos are processed and are not stored permanently.
