Privacy Policy

Effective Date: May 8, 2026

H2A Digital ("we," "us," or "our") operates the Crystal mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.

📊 Information We Collect

Personal Information

  • Rock and Crystal Photos: Uploaded for identification and removed after processing
  • Identification Data: Detection results, confidence, and selected matches

Automatically Collected

  • Device Information: Device type, OS, identifiers
  • Analytics: PostHog data to improve services
  • Usage Data: Features accessed and actions taken

🧩 Third-Party Data Storage (Service Providers)

Supabase (Backend & Storage)

Do they store uploaded data? Yes. Supabase temporarily stores: uploaded rock and crystal photos in Supabase Storage under our account.

Why do they store it? We upload rock and crystal photos to create a short-lived signed URL that our backend uses to securely retrieve the image during processing. This avoids sending large image files inside the identification request payload and improves reliability (e.g., if the app is backgrounded or a retry is needed).

How long is it stored?
  • Rock and crystal photos: We delete uploaded rock and crystal photos after the identification attempt completes. If deletion fails due to network or unexpected errors, we run automated cleanup to remove any remaining photo uploads within 6 hours.

Why this length? The 6-hour window exist only as short reliability fallbacks (e.g., client disconnects, network errors, or retries) while minimizing retention of uploaded photos.

PostHog (Analytics)

Do they store uploaded photos? No. We do not send uploaded photos to PostHog.

What do they store instead? PostHog receives usage/analytics events (e.g., screen views, button taps, feature usage) to help us improve the App.
