Privacy Policy

Last updated: September 10, 2026

CardCalc LLC ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and protect your information when you use the CardCalc app and website.

1. Information We Collect

CardCalc LLC collects minimal information to provide its services:

• Calculator sessions: Card names, prices, and percentages you enter are stored locally on your device only. We do not transmit this data to our servers.
• Slab Scanner data: Certificate numbers, cert images, comp prices, and offer percentages you scan, enter, or edit are stored locally on your device.
• Subscription information: Managed entirely by Apple's App Store. We do not collect or store your payment information.
• App preferences: Settings such as default percentages and currency are stored locally on your device.
• Support communications: If you contact us by email, we receive your email address and message content.

2. Camera Access

CardCalc requests camera access for the Slab Scanner feature (Pro):

• The camera is used to read the barcode or QR code printed on a graded card's slab label.
• The scanned certificate number is sent to CheckCOA, a third-party verification service, to identify the card and check for fraud reports.
• No photo of the card or slab is captured, stored, or transmitted as part of this process — only the certificate number read from the barcode/QR code.

If photo-based card identification is reintroduced in a future update, this Privacy Policy will be updated to reflect that before the feature is enabled.

3. Third-Party Services

CardCalc uses the following third-party services to provide functionality:

• Poketrace — provides card pricing and price history data. Card search queries are sent to their servers. See poketrace.com for their privacy policy.
• CheckCOA — provides graded card certificate verification and fraud-report checking for the Slab Scanner feature. Certificate numbers you scan or manually enter are sent to their servers for processing. See checkcoa.com for their privacy policy.
• Apple App Store — handles all subscription payments and in-app purchases.
• TCGPlayer — card links may direct you to tcgplayer.com in your browser.

4. Data Storage

Most data in CardCalc is stored locally on your device using iOS secure storage. This includes your calculator sessions, saved card lists, scanned slab data, session history, app settings, and subscription status. This data remains on your device and is not transmitted to CardCalc LLC servers. You can delete this data at any time by uninstalling the app or using the Clear History / Clear All options in Settings and the Slab Sheet.

5. Analytics and Crash Reporting

CardCalc does not currently use any analytics or crash reporting services. We do not track your usage of the app or collect behavioral data.

6. Children's Privacy

CardCalc is not directed at children under 13. CardCalc LLC does not knowingly collect personal information from children under 13. If you believe a child has provided personal information through our service, please contact us at phu@cardcalcapp.com.

7. Your Rights

Since CardCalc stores data locally on your device, you have full control over your data:

• Delete all app data by uninstalling CardCalc
• Clear session history in Settings → Clear History
• Clear scanned slab data in the Slab Sheet's Clear All option
• Manage or cancel your subscription through Apple ID settings
• Contact us to request information about any data we may hold

8. Security

CardCalc LLC takes reasonable measures to protect your information. All API communications use HTTPS encryption. Your data is stored using iOS secure storage mechanisms. We do not store sensitive personal or financial information on our servers.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of significant changes through the app. Continued use of CardCalc after changes are posted constitutes acceptance of the updated policy.
