Privacy Policy for NumisTrack Last updated: 17/05/2026
NumisTrack ("we", "our", or "us") respects your privacy. This policy explains what information we collect, how we use it, and your rights regarding your data.
Information We Collect
Account Information If you sign in with Google or Apple, we collect and store your email address and a unique account identifier. This is used only to identify your account, enable cloud sync, and associate your collection data with you. We do not access your password or any other account data beyond what is listed here.
Collection Data If cloud sync is enabled, your NumisTrack data — including coins, notes, grades, values, wishlist items, and sales history — is stored on secure cloud infrastructure to enable backup, sync across devices, and restore on reinstall. This data is associated with your account identifier and is never shared with other users.
Push Notification Tokens If you enable push notifications, we store a device token on our servers. This token is used only to send you eBay price alerts when a coin on your wishlist matches your target price. We do not use push tokens for marketing or any other purpose.
Purchase Information If you purchase Collector Plus or Remove Ads, we receive a purchase token and transaction ID from Apple or Google. These are sent to our backend solely to verify your purchase and apply your entitlement. We do not store full payment details.
How Your Data Is Used
Your data is used only to:
Provide core app functionality
Enable cloud backup and multi-device sync
Send eBay price alert notifications you have requested
Verify in-app purchases
We do not sell, rent, or share your personal data with third parties for marketing purposes.
