Privacy Policy

Last updated: March 7, 2026

Overview

MintPick ("we", "our", "the app") is a card centering measurement tool. We are committed to protecting your privacy. This policy explains what data we collect and how we use it.

Data We Collect

Your card images and measurement data are never uploaded to any server. All image processing and measurements happen entirely on your device. However, the app uses third-party services (listed below) that may collect limited technical data such as crash reports and device identifiers.

Local Storage

The app stores the following data locally on your device:

• Card images you scan (saved to app storage)
• Measurement results and grades
• Your Board and Stack organization
• App preferences

This data never leaves your device unless you explicitly export or share it.

Third-Party Services

The app uses the following third-party services:

• Google AdMob — displays banner advertisements to free-tier users. AdMob may collect device identifiers and usage data for ad personalization. See Google's Privacy Policy.
• RevenueCat — manages in-app subscriptions. RevenueCat processes purchase transactions through Apple/Google. See RevenueCat's Privacy Policy.
• Sentry — collects crash reports and error diagnostics to help us fix bugs. Sentry may receive device type, OS version, and stack traces when the app encounters an error. No card images or measurement data are included. See Sentry's Privacy Policy.

App Tracking Transparency

On iOS, we request your permission before allowing third-party services to track your activity across other apps. You can change this setting at any time in your device's Settings > Privacy > Tracking.

Your Rights

• Opt out of ad personalization — on iOS, deny tracking in the App Tracking Transparency prompt, or go to Settings > Privacy > Tracking at any time.
• Delete your data — all data is stored locally on your device. Deleting the app removes all your data completely.
• California residents (CCPA) — we do not sell your personal information. You have the right to know what data is collected and to request deletion.
• EU residents (GDPR) — you have the right to access, correct, and delete your personal data. Since all data is local, deleting the app fulfills these rights.

Children's Privacy

The app is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
