Last updated: September 26, 2026

This Privacy Policy explains how Market Pulse Sport Card Prices (“Market Pulse Sport Card Prices”, “we”, “us”) collects, uses, and shares information when you use our website, browser extensions (Chrome, Edge, and Firefox), and related services.

We do not sell your personal information. Questions? Contact support@cards-mp.com.

Summary

  • We collect account, payment, and usage data to provide and improve the Services.
  • We do not sell your personal information.
  • You can access or correct your data, and signed-in users can delete their account from account settings. You can also contact us at support@cards-mp.com.

Information We Collect

Information you provide

  • Account details (name, email, password), plan selections, and support messages.
  • Payment transactions for paid subscriptions are handled by Stripe, our third-party payment processor.

Information collected automatically

  • Log data (IP address, device/browser type, referring/exit pages, timestamps, error logs).
  • Usage data from the extension and website (features used, performance metrics, limited event telemetry).
  • Cookies/Local Storage for session management and preferences.

How We Use Information

  • Provide, maintain, and secure the Services.
  • Process payments and manage subscriptions.
  • Improve features, research aggregates, and troubleshoot issues.
  • Send transactional notices (receipts, service alerts). You can control non-essential emails.
  • Contract (to provide the Services you requested).
  • Legitimate interests (improving, securing, and supporting the Services).
  • Consent (where required, for example, certain analytics or marketing).

How We Share Information

  • Vendors/Processors: hosting, support and communications, analytics, error monitoring, email delivery, and payments. Only what’s needed to perform their services.
  • Legal/Compliance: to comply with law, enforce terms, or protect rights, safety, and security.
  • Business transfers: in connection with a merger, acquisition, or asset sale.

Payments

Payment transactions for paid subscriptions are handled by Stripe, our third-party payment processor. You can review Stripe’s Privacy Policy for more information about how Stripe handles payment data.

Cookies & Similar Technologies

We use cookies/local storage for authentication, preferences, and analytics. You may control cookies via your browser settings; disabling them may impact functionality.

Analytics & Telemetry

We use privacy-conscious analytics and minimal telemetry to understand aggregate usage and performance. Where required, we request consent and honor opt-out settings. Telemetry from the extension avoids collecting page content and focuses on feature usage and errors.

Extension problem reports

When you voluntarily submit a browser-extension problem report, troubleshooting context may include the listing title, item ID, listing URL, parsed title, and error information. We do not continuously collect ordinary browsing URLs.

Data Retention

We retain personal data for as long as necessary to provide the Services, comply with legal obligations, resolve disputes, and enforce agreements. We also preserve aggregated, de-identified statistics.

If you delete your account, access is disabled immediately. We retain a limited deletion record for 90 days for billing and transaction reconciliation, fraud prevention, legal/compliance needs, and operational auditing. After that period, the remaining account record is permanently deleted.

Security

We use administrative, technical, and organizational safeguards appropriate to the risk, including encryption in transit, least-privilege access, and continuous monitoring. No method of transmission or storage is 100% secure.

Children’s Privacy

The Services are not directed to children under 13 (or the minimum age required by your jurisdiction). We do not knowingly collect personal information from children.

Your Rights & Choices

  • Access, correction, deletion, or portability of your personal data.
  • Object to or restrict certain processing, and withdraw consent where applicable.
  • Opt-out of non-essential communications.

To exercise rights, contact us at support@cards-mp.com. We may request verification.
