Terms of Service

Effective November 1, 2026

These Terms of Service ("Terms") govern your access to and use of CardVine, a product of StatZhub Consulting LLC ("CardVine," "we," "us," or "our"). By creating an account or otherwise using CardVine, you agree to these Terms. If you don't agree, please don't use the Service.

1. The Service

CardVine helps you catalog your trading card collection, see estimated market values, connect with other collectors, list cards for sale, make and accept offers, and propose and complete trades. CardVine is a platform that helps collectors find each other and coordinate sales and trades — we are not a party to any sale or trade you make, and we don't buy, sell, appraise, authenticate, or take possession of any cards.

2. Accounts

• You must provide accurate information when creating your account and keep it up to date.
• You're responsible for maintaining the security of your account and password, and for all activity that occurs under your account.
• You must be at least 13 years old to use CardVine.
• CardVine is available only in the United States. To use it you must live in the United States and have a valid US address, which you provide when you create your account and keep up to date. Shipping, seller payouts, and Buyer Protection are available only for US addresses and US bank accounts. We may limit or close an account that doesn't meet these requirements.
• You may delete your account at any time; some information may be retained as described in our Privacy Policy.

3. Plans, subscriptions, and payments

Plans. CardVine offers a free Basic plan and two optional paid plans, billed monthly: Premium (currently $4.99 per month) and Premium Card Shop (currently $9.99 per month). Premium lowers your selling fee (see Section 4), lets you promote up to 3 of your for-sale cards, and adds a Premium badge to your profile. Premium Card Shop includes everything in Premium, plus a Verified Card Shop badge, your shop name on your profile, and the ability to promote up to 3 events. We may change plan features and prices; for an existing subscription, a price change takes effect at your next renewal after we notify you.

Card scanning. Scan a Card is included in every plan, with a limit on how many scans you can make in a calendar month: 250 on Basic, 1,500 on Premium, and 5,000 on Premium Card Shop. The count starts over on the first day of each month (UTC), and the number of scans you have left is shown when it runs low. A scan sends your photo to a third-party recognition service to find the closest matching cards (see our Privacy Policy). Results are best matches, not a guarantee of what a card is or what it is worth, so check a card before you list or trade it. We may change the limits, and we may limit or suspend scanning that looks automated, abusive, or an attempt to get around these limits.

Billing and cancellation. Paid plans are billed in advance on a recurring monthly basis until canceled, and payments are processed by Stripe. Applicable taxes are added at checkout. You can cancel at any time from the Plans page in the app; cancellation takes effect at the end of the current billing period, you keep your plan until then, and we don't provide prorated refunds for partial periods except where required by law. When a paid plan ends, your selling fee returns to the Basic rate and your promotions end.

Premium Card Shop verification. Premium Card Shop is available only to businesses we verify. To apply you must give your shop name, address, and company identifier, and the information must be accurate. We review each application and may approve it, decline it, or ask for more information; you are not charged for the Card Shop plan until your shop is verified. We may remove the Verified Card Shop badge and end the plan if the information turns out to be inaccurate or if you violate these Terms. A badge is not an endorsement: CardVine does not guarantee a verified shop's cards, prices, or service.

Promoted listings. Paid plans let you promote cards or events so they are shown to other users in the app. Promotion does not guarantee views, offers, or sales, and the order and rotation of promoted items may vary. Promoted items must follow these Terms and our Community Guidelines, and we may remove a promotion at any time.

Price estimates shown in the app are informational only, based on available market data, and are not appraisals, guarantees of value, or offers to buy or sell.

4. Selling and trading between users

CardVine lets you list cards for sale, make and accept cash offers, buy cards, and propose and accept trades with other users. Where you choose to complete a sale or trade through CardVine, the following applies.

• We are not a party to your sales or trades. They are agreements between you and the other collector. CardVine does not inspect, authenticate, grade, insure, or guarantee the condition, authenticity, or value of any card.
• We never take possession of cards. Cards ship directly between users.
• Direct payments. When you buy a card, or pay the cash portion of a trade, through CardVine, your payment is processed by Stripe and sent directly to the seller's Stripe account when the payment succeeds, less CardVine's selling fee and the payment processor's fees. CardVine does not hold your money while the card is on its way, and CardVine is not a bank. The money is in the seller's Stripe balance right away. CardVine pays a seller's balance out to their bank account 30 days after each sale, which covers the Buyer Protection period; Stripe's own processing times and the seller's account status also apply.
• Seller payouts. To sell for cash, you must set up a payout account with Stripe and accept Stripe's terms. Until you have, buyers cannot pay you through CardVine. Payouts from your Stripe balance to your bank account are sent 30 days after each sale.
• Buyer Protection. Eligible purchases are covered by CardVine Buyer Protection, described in our Refund Policy, which is part of these Terms. Under it, a buyer may be refunded if an item never arrives or is significantly not as described. If a claim is approved because of the seller, the refund may be recovered from the seller's payout account, and a seller who cannot cover it may have their account limited.
• Selling fee. When you ship a card away through CardVine — selling it for cash, or giving it up in a card-for-card trade — you owe CardVine a selling fee of 10% of the card's value on the Basic plan, or 5% on Premium and Premium Card Shop, with a minimum of $1 per sale. The fee is deducted from the payment before it is sent to you or, where there is no cash to deduct it from, charged to you at checkout, and it is returned if the order is refunded. It is not charged twice on the same shipment. The payment processor's fees (card processing and payout fees) are also deducted from a seller's payout.
• Shipping labels. You can buy a tracked shipping label through CardVine at the carrier's cost, plus a handling fee of 7% of the label's postage cost on the Basic plan (5% on Premium and Premium Card Shop) and payment processing. The handling fee is charged to whoever pays for the label, is in addition to the selling fee, and is refunded with the label if the label purchase fails but is otherwise not refundable. A tracked label is required for shipments valued above $50; below that you may ship untracked, in which case CardVine cannot help trace a lost shipment and the selling fee still applies. A cash sale over $100 must ship insured for the full order value; the insurance premium is added to the label checkout. A label is not insurance, and CardVine does not guarantee delivery and is not responsible for lost, delayed, or damaged shipments, subject to whatever coverage (if any) you purchase or the carrier or shipping partner provides for that shipment.
• Refunds. Refunds are handled under our Refund Policy. Payment processing fees may not be refundable.
• Chargebacks. If a buyer disputes a card payment with their bank or card issuer, the seller bears the loss as described in Section 8 of our Refund Policy: if a dispute is lost or cannot be contested in time, the disputed amount and the dispute fee are recovered from the seller. By selling through CardVine you authorize CardVine, to the extent permitted by Stripe's terms and applicable law, to reverse transfers to your Stripe account, debit your Stripe balance, withhold or offset payouts, and limit your account until the amount is repaid. You agree to respond to dispute requests promptly and to repay any amount we cannot recover from your payouts. Buyers agree not to dispute a payment for a purchase they received as described, or one already refunded, and we may limit or close the account of a buyer who does.
• Your responsibility. You're solely responsible for evaluating who you buy from, sell to, or trade with and what you trade. We encourage you to deal only with collectors you trust and to use the ratings and community features to make informed decisions.
• Disputes. CardVine is not responsible for resolving disputes between users and does not guarantee any particular outcome. Claims about a purchase are decided under our Refund Policy. We may also, at our discretion, review other disputes and suspend accounts involved in reported abuse.

5. Acceptable use

You agree not to:

• Use CardVine for any illegal purpose, or to defraud or attempt to defraud another user
• Misrepresent a card's identity, grade, authenticity, or condition when trading
• Harass, abuse, or threaten other users, or post hate speech
• Post sexual, graphically violent, or otherwise objectionable content, or any content that sexualizes or exploits minors
• Pressure other users to pay or trade outside CardVine, send spam, or impersonate another person
• Advertise or promote outside businesses, services, or websites, or post links to outside sites to do so. Posts, comments, and events that contain a link are held for review before other people can see them, and links are not allowed in message requests, trade notes, profile text, or community names and descriptions
• Upload content you don't have the right to share, or that infringes another party's intellectual property
• Attempt to interfere with, disrupt, or gain unauthorized access to the Service
• Use automated means to scrape or access the Service outside of its intended use

CardVine has zero tolerance for objectionable content or abusive behavior. Any user can report a post, photo, comment, or conversation, and can block any other user at any time. Reported posts, photos, and comments are hidden from other users while our team reviews them, and we also use automated checks on posts, comments, and photos. Private direct messages are not scanned automatically and are reviewed only if reported. We may remove content, restrict an account for a period of time, or permanently terminate it, and we may report unlawful content to the appropriate authorities and retain it as the law requires. If you believe we made a mistake, contact support@cardvine.app. See our Community Guidelines in the app for details.

5A. Communities

Any user may create a community. The person who creates a community may choose rules for it from the options we provide and add their own, and may remove members who do not follow those rules; a removed member cannot rejoin unless the creator allows it. Community creators are not our employees or agents and do not speak for CardVine, and they can only act inside their own community. Everyone must follow our Community Guidelines in every community, whatever the community's own rules say. We may remove any community, post, or member, or restrict a creator's tools, at any time, and a user who is removed from a community can contact support@cardvine.app.

6. Your content

You retain ownership of the content you upload to CardVine (such as card photos, posts, and messages). By uploading content, you grant CardVine a non-exclusive, worldwide license to host, store, and display that content solely as needed to operate the Service. You're responsible for making sure you have the right to share any content you upload, including respecting the intellectual property of card games, publishers, and other rights holders.

7. Third-party services

CardVine relies on third-party services — including Stripe for subscriptions, payments, seller payouts, and tax; our shipping partner for label generation; Resend for email; OpenAI for content moderation; Scrydex for card recognition and card data; Cloudflare for bot protection (CAPTCHA); our hosting provider; and third-party card databases for search results, prices, and images — to operate. Your use of those integrated services is also subject to those providers' own terms, including Stripe's terms for sellers who receive payouts.

8. Disclaimers

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DON'T WARRANT THAT PRICE ESTIMATES ARE ACCURATE, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CARDVINE AND STATZHUB CONSULTING LLC WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF CARDS, VALUE, DATA, OR PROFITS, ARISING FROM YOUR USE OF THE SERVICE OR ANY TRADE CONDUCTED THROUGH IT, EVEN IF WE'VE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID TO CARDVINE IN THE 12 MONTHS BEFORE THE CLAIM AROSE.

10. Termination

You may stop using CardVine and delete your account at any time. We may suspend or terminate your access to the Service if you violate these Terms or if we reasonably believe doing so is necessary to protect CardVine or other users.

11. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we'll notify you by updating the effective date above and, where appropriate, through the Service. Continued use of CardVine after changes take effect means you accept the updated Terms.

12. Governing law

These Terms are governed by the laws of the State of California, United States, without regard to its conflict-of-laws principles.
