Privacy Policy

Effective September 24, 2026 · Last updated September 24, 2026

This policy explains how CardMint (“CardMint”, “we”, “us”) collects, uses, shares and protects information about you when you use the CardMint website at cardmint.co and its related services (the “Service”), and the choices and rights you have. If you have a question, contact us at privacy@cardmint.co.

The short version

1. Information we collect

Information you give us

Information collected automatically

Information from other sources

2. How we use information

We do not use your information for targeted advertising, and we do not use your card photos or messages to train artificial intelligence models.

3. How we share information

We do not sell your personal information. We share it only as described here.

Service providers

These companies process information on our behalf, only to provide their services to us:

eBay, when you choose to list

When you list a card, we send eBay the listing you approved (title, description, item specifics, price, condition and the card's photos) to publish under your eBay account. eBay's use of it is governed by eBay's own privacy notice. The buyer's details and payment stay with eBay and are not shared with us.

Other sharing

4. What other people can see

5. Cookies and similar technologies

CardMint uses one cookie: a strictly necessary sign-in cookie named session that keeps you signed in for up to 7 days. It is marked HttpOnly (web page scripts can't read it) and, on our secure site, Secure. We also use your browser's session storage to remember scanner settings during a visit; it is cleared when you close the tab.

We do not use advertising cookies, cross-site tracking, or third-party analytics services. Because we don't track you across other websites or sell or share your information for advertising, browser “Do Not Track” and Global Privacy Control signals don't change how CardMint works. We treat a Global Privacy Control signal as a valid request to opt out of sale and sharing, which we already don't do.

6. How long we keep information

We keep information only as long as we need it for the purposes above:

We may keep information longer where the law requires it, or to resolve disputes, prevent fraud and abuse (for example, to keep a banned account from returning), or enforce our agreements.

7. How we protect information

We use reasonable administrative, technical and physical safeguards, including encryption in transit (HTTPS), salted one-way password hashing, encryption of eBay access tokens at rest, limits on repeated sign-in attempts, and restricting administrative access to authorized staff. No method of transmission or storage is completely secure, so we can't guarantee absolute security. If a breach affects your personal information, we will notify you and the authorities as required by law.

8. Your rights and choices

Things you can do yourself

Requests you can make

Depending on where you live, you may have the right to:

To make a request, email privacy@cardmint.co from the email address on your account, or message us through Questions & Feedback while signed in. We will verify your request by confirming it comes from your account's email address, and respond within 30 days (or within the time your local law requires, which we may extend where the law allows, telling you why). We won't discriminate against you or charge you more for exercising your rights.

Authorized agents: you may have someone make a request on your behalf. We'll ask for proof of their authority and may ask you to confirm your identity directly.

Appeals: if we decline your request, you can appeal by replying to our decision with “Appeal” in the subject line. We'll respond within the time required by law. If you're not satisfied, you may contact your state attorney general.

9. Additional information for U.S. state residents

This section applies to residents of California and other U.S. states with comprehensive privacy laws. In the past 12 months we have collected the following categories of personal information, for the business purposes described in section 2, and disclosed them only to the service providers and recipients described in section 3:

We do not sell personal information or share it for cross-context behavioral advertising, and have not done so in the past 12 months. We do not knowingly sell or share the personal information of consumers under 16. We use sensitive personal information only to provide the Service, so there is no need to limit its use. We do not disclose personal information to third parties for their own direct marketing (California “Shine the Light” law).

10. Additional information for the EEA, UK and Switzerland

CardMint is the controller of your personal information. We rely on these legal bases:

You have the right to lodge a complaint with your local data protection authority.

11. International transfers

CardMint is based in the United States, and our service providers process information in the United States and other countries. Where the law requires, we rely on appropriate safeguards, such as the European Commission's Standard Contractual Clauses, for transfers of personal information from the EEA, UK or Switzerland.

12. Children

CardMint is not directed to children under 13, and we do not knowingly collect personal information from children under 13 (or under 16 in the EEA and UK). If you are under 18, use CardMint only with the permission and supervision of a parent or guardian; purchases must be made by an adult. If you believe a child has given us personal information, contact us and we will delete it.

13. Third-party services

CardMint links to and works with services we don't control, including Stripe (payments) and eBay (listings and price information). Their own privacy policies govern how they handle your information, and we encourage you to read them.

14. Changes to this policy

We may update this policy from time to time. We'll change the “Last updated” date above, and if a change is material we'll tell you by email or with a notice on CardMint before it takes effect. Please review this policy periodically.
