Privacy Policy

We only collect what the app needs to work:

• Account info. Your email address, used to create and sign you into your account.
• Your collection. The coins you add — details like year, mint, grade, metal, notes, purchase price, and any photos you take or upload.
• Coin photos. When you scan or add a coin, the image is processed to identify the coin and stored with your collection.
• Usage analytics. Basic, aggregated product analytics (pages viewed, features used) to improve the app. This is not sold and not used to track you across other apps or websites.
• Payment info (web only). If you subscribe, payments are handled by our payment processor. We never see or store your full card number.

• To operate your account and store your collection.
• To identify coins and estimate their value from your photos and details.
• To provide pricing, set-completion tracking, and metal prices.
• To keep the app secure and to improve it over time.

We do not sell your personal information, and we do not use it for third-party advertising.

We share data only with the vendors that power the app, and only so they can perform their function for us:

• Supabase — authentication, database, and photo storage.
• AI identification providers — your coin photos are sent to an AI vision service to identify the coin. Images are used to fulfill your request, not to train models.
• Stripe — subscription payments (web only).
• Product analytics — aggregated usage measurement.

We may also disclose information if required by law or to protect the rights, safety, and security of our users and the service.

We keep your data for as long as your account is active. When you delete your account, your collection, photos, and personal data are permanently deleted from our systems. Some records may persist briefly in encrypted backups before they age out.

You can permanently delete your account and all associated data at any time:

• In the iOS app: Settings → Delete account.
• On the web: your account settings, or email us at support@coinstacker.ai.

This action is immediate and cannot be undone.

Depending on where you live, you may have the right to access, correct, export, or delete your personal data. You can exercise these rights in the app, or by contacting us at support@coinstacker.ai.

Coin Stacker is not directed to children under 13, and we do not knowingly collect personal information from them.

We may update this policy as the app evolves. When we do, we'll revise the “last updated” date above, and for material changes we'll provide a more prominent notice.
