Stone & Coin Privacy

Last updated: October 13, 2026

This Privacy Policy explains what information Stone & Coin Worth AI (a WorthScan AI app) collects, how it is used, and the choices you have. The app provides AI-assisted Stone Scanner and Coin Scanner analysis.

Information we collect

• Account email — used to create and manage your account.
• Uploaded or captured scan photos — stone, mineral, or crystal photos submitted to Stone Scanner and front/back coin photos submitted to Coin Scanner.
• Scan inputs and analysis data — details you provide about an item and the resulting identification, observations, confidence, uncertainty, and value-context results.
• My Finds — scan results and items you choose to save in the app.
• App usage and allowances — information needed to operate your account, total scan credits, Coin allowance, and app features.
• Purchase and subscription status — information needed to recognize access purchased through the Apple App Store or Google Play and restore eligible purchases. Payment details are handled by the applicable app store, not directly by us.

How your photos are used

Photos and related item details are used to provide the scan you request: likely identification and educational or value context for stones, minerals, and crystals; and identification, visible evidence, estimated condition, collector significance, and classification for coins. Please do not upload personal or sensitive photos unrelated to checking an item.

Service providers

• Supabase — used for authentication, database, storage, and backend services.
• AI service providers — used to perform AI-assisted scan analysis on submitted photos and details.
• Email delivery provider (such as Brevo) — used to send account-related emails, such as sign-in and password-reset messages.
• Apple App Store and Google Play services — used for app distribution, in-app purchases, subscriptions, and purchase restoration.

Retention and deletion

Account data, saved finds, scan history and results, and uploaded scan photos may be retained while your account is active so the app can provide its features. You can delete saved finds in the app. You can also delete your account and associated data in the app where available, or request deletion through our Delete Account & Data page. Some records may be retained temporarily where required for security, fraud prevention, legal, operational, or compliance reasons.

Your choices and controls

• You can delete saved finds in the app.
• You can delete your account and associated data in the app where available.
• You can contact us for privacy questions or data deletion requests at the email below.
