Numistry is built on honesty, and that includes how we treat your data. This policy explains what the Numistry mobile app and the numistry website collect, what they don't, and where your information goes. The short version: no account is required, your collection stays on your device, and we never sell your data.
Coin photos you scan. When you scan a coin, the photo is sent over an encrypted connection to our server so our AI can identify it. The photo is processed to produce your result and is not used to build advertising profiles. AI analysis is performed by Anthropic's Claude API as a data processor; per Anthropic's commercial API terms, API inputs are not used to train their models.
Your collection. Coins you save are stored locally on your device only. We do not have a copy. If you delete the app, your collection data is deleted with it.
Purchase information. Subscriptions are processed by Apple's App Store or Google Play — we never see your card number. Our subscription partner, RevenueCat, receives an anonymous app identifier and purchase status so the app knows you're a Pro subscriber.
Waitlist email (website only). If you join the waitlist on our website, your email address is collected via Formspree and used only to tell you about Numistry's launch and major updates. Every email includes a way to opt out. No spam, ever.
We share data only with the vendors that make the product work, and only what they need:
Scan photos are processed to generate your result and are not retained as a photo archive tied to your identity. Waitlist emails are kept until you unsubscribe or we delete the list after launch outreach. Collection data lives on your device and is yours.
Numistry is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.
You can request access to, or deletion of, any personal data we hold (in practice: your waitlist email) by contacting us. Depending on where you live (e.g., EU/EEA, UK, California), you may have additional rights under local law, and we honor reasonable requests regardless of geography.
If we make material changes, we'll update the effective date above and, for significant changes, note it in the app or by email to the waitlist.
