Effective Date: June 22, 2026
Last Updated: October 12, 2026
1. Overview
Darshn ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the Darshn mobile application ("App"). If you do not agree with its terms, please discontinue use of the App.
2. Data We Collect
2.1 Information You Provide
- Account information: email address, display name, and password via Firebase Authentication when you create an account. Guest use may create an anonymous Firebase identity.
- Early-access requests: the contact email and message you send to us by email. The website opens a draft; you choose whether to send it.
- Fitness profile: age, height, weight, fitness goals, dietary preferences, and training history.
- Workout logs: exercises performed, sets, reps, weights, and session durations.
- Nutrition logs: food items, macro estimates and ranges, meal photos, hydration, and corrections.
- In-app settings: notification preferences, display settings, and developer flags.
2.2 Data Collected Automatically
- Usage data: screens visited, features used, and interaction timestamps.
- Crash reports and diagnostics: error logs, stack traces, and device metadata where enabled.
- Analytics events: aggregated events about feature usage.
2.3 Health & Fitness Data
With your explicit permission, supported builds read selected health data through Android Health Connect or Apple HealthKit on iOS. The current health integration requests read access to steps, sleep, resting heart rate, and heart rate variability. Availability depends on your device and the permissions you grant.
Health Connect or HealthKit data is used solely to personalize your experience within Darshn and is never sold to third parties or used for ad targeting.

Food photo analysis and plan generation use cloud services. Selected coaching features can run on-device after a model download; availability and fallback behavior vary by feature. AI-generated recommendations are for informational and motivational purposes only and do not constitute medical, nutritional, or professional fitness advice.
Always consult a qualified healthcare professional, registered dietitian, or certified personal trainer before making significant changes to your diet or exercise program.
