Luster

Privacy Policy

Last updated: March 23, 2026

1. Who We Are

Luster ("we," "us," "our") is a precious metals collection management platform. This Privacy Policy explains how we collect, use, store, and protect your information when you use our website and services at collecttheshiny.com.

2. Information We Collect

Account Information

When you create an account, we collect your email address and display name through our authentication provider, Clerk. We do not store passwords — authentication is handled entirely by Clerk.

Collection Data

You provide information about your precious metals collection, including item descriptions, purchase details, photos, notes, storage locations, and valuations. This data is stored in our database hosted by Convex.

Photos

Photos you upload are stored using Vercel Blob storage. Photos are private by default and only shared when you explicitly create a public showcase link.

Usage Data

We collect standard web analytics data including pages visited, browser type, and device information to improve the service.

3. How We Use Your Information

  • To provide, maintain, and improve the Luster platform
  • To process your collection records and calculate valuations using live spot prices from metals.dev
  • To power AI features (identification, research, enrichment) using Anthropic's Claude API — your item data is sent to Anthropic for processing but is not used to train their models
  • To process payments through Clerk Billing (powered by Stripe) if you subscribe to a paid plan
  • To send transactional emails related to your account
  • To respond to support requests

5. Data Storage and Security

Your data is stored on servers in the United States. We use industry-standard security measures including encryption in transit (TLS), secure authentication via Clerk, and access controls on our database. Collection data is private by default — nothing is publicly visible unless you explicitly choose to share it.

6. Data Retention and Deletion

We retain your data for as long as your account is active. You can export all your data at any time as JSON or CSV. You can delete individual items or your entire account. When you delete your account, all associated data is permanently removed from our systems within 30 days.

7. Your Rights

  • Access: You can view and export all your collection data at any time
  • Correction: You can edit any record in your collection
  • Deletion: You can delete individual items or your entire account
  • Portability: Export your full collection as JSON or CSV

8. We Do Not Sell Your Data

We do not sell, rent, or share your personal information or collection data with third parties for marketing purposes. Your collection is yours.

9. Cookies

We use only functional cookies necessary for authentication and session management. We do not use tracking cookies or third-party advertising cookies.

10. Changes to This Policy

We may update this policy from time to time. We will notify you of material changes by posting the updated policy on this page with a new "Last updated" date.
