Terms of Service

Version 2026-09-15 · Effective 15 September 2026 · Last updated 15 September 2026

These terms are the agreement between you and us for using Cardonomics. We have written them in plain English. Please read them, especially the parts on subscriptions, on the information being for reference only, and on how disputes are resolved.

1. Accepting these terms

Cardonomics is a DBA of Powerhouse Holdings, LLC, an Alabama limited liability company (“Cardonomics”, “we”, “us”). These Terms of Service (“Terms”) cover your use of cardonomics.io and everything it offers: the pages, the data, the account features, the exports and the API (together, the “Service”).

By creating an account, starting a subscription, or otherwise using the Service, you agree to these Terms and to our Privacy Notice, which explains how we handle personal information. If you do not agree, do not use the Service.

2. Who can use Cardonomics

You must be at least 13 years old. Nobody under 13 may use the Service or create an account.
If you are 13 to 17, you may use the Service only with the permission of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your use.
Only adults may pay. You must be 18 or older, and the age of majority where you live, to buy a subscription. A parent or guardian may buy one for a teen they supervise.
You may not use the Service if the law forbids you to, or if we have previously closed your account for breaking these Terms.

If we learn that an account belongs to someone under 13, we will close it and delete its personal information.

3. Your account

You can sign in with Google or with an email address and password. Give accurate information and keep it up to date. One account is for one person; do not share your sign-in or let anyone else use your account. You are responsible for what happens under your account, so keep your password safe. You can see and sign out every device under Settings → Security. If you think someone else has got into your account, change your password and tell us at [email protected].

4. Subscriptions, billing, cancellation and refunds

Plans and the free trial

Some features are free and others need a paid plan. The pricing page shows what each plan costs and includes, and says plainly which features are not switched on yet. A new account gets a free trial of a paid plan, currently 7 days. No card is needed for the trial, and it never turns into a paid subscription on its own. When the trial ends, the account moves to the free plan and nothing is deleted. You are only charged if you choose a paid plan and check out.

Payment and automatic renewal

Payments are processed by our payment processor, Stripe. Card details are entered on Stripe's pages and never reach our servers. Paid plans are billed monthly, in advance, and renew automatically each month at the then-current price until you cancel. By checking out you authorise us, through Stripe, to charge your payment method each month until you cancel. Prices are shown before you pay. Any sales tax or similar tax that applies will be added.

If a payment fails, we may retry it, and the account may lose paid features until the payment goes through.

Cancelling

You can cancel at any time from Settings, which opens Stripe's billing portal, or by writing to [email protected]. Cancelling stops future renewals. You keep paid features until the end of the month you have already paid for, and then the account moves to the free plan. Cancelling does not delete your account; you can do that separately (see section 14).

Refunds

Payments cover the month already started, so we do not give refunds or credits for part of a month, unused features, or a month in which you did not use the Service, except where the law requires it. If the Service was broken on our side for a significant stretch, write to us and we will look at it fairly.

Price changes

We may change our prices. If the price of a plan you are on changes, we will tell you by email or on the Service before the new price applies to you, and it will take effect at your next renewal after that notice. If you do not want to pay the new price, cancel before then.

5. Acceptable use

You agree not to, and not to help anyone else to:

scrape, crawl or copy the Service or its data by automated means, or run automated bulk extraction against it, other than through the exports and API your plan includes, used within their limits;
resell, redistribute, sublicense or publish our data or calculations, or build a competing product or dataset from them, without our written permission;
get around plan limits, rate limits, access controls or security measures, or probe, scan or test the Service's weaknesses (except under our security reporting policy);
use the Service to harass, threaten, stalk, dox or intimidate anyone, including breakers, sellers and buyers;
try to identify, contact or profile individual buyers or bidders from anything the Service shows;
claim a stream handle that is not yours, or pretend to be someone else;
upload or send malware, or interfere with or overload the Service;
use the Service for anything unlawful, including any break, sale or promotion that breaks the law where it happens.

If you want to use our data for something we do not offer, ask us first at [email protected].

6. Our content and your license to use it

The Service, including its software, design, text, the Cardonomics name and logo, and the way we collect, organise, calculate and present data, belongs to us or our licensors and is protected by law. Subject to these Terms and your plan, we give you a limited, personal, non-exclusive, non-transferable, revocable license to use the Service for your own collecting or breaking. You may download exports your plan includes for that same purpose. Everything not expressly granted is reserved.

If you send us suggestions or feedback, we may use them without owing you anything.

7. Your content and stream handle claims

You keep what you own in the settings, watchlists and other information you put into your account. You give us permission to store and use it to run the Service for you.

A breaker can link a live-stream handle to their account to see their own figures. You may claim only a handle you own or are authorised to act for. We verify a claim before it opens anything, and we may refuse or remove a claim, or ask for more proof, at any time. Linking a handle does not give you rights over what other people say or sell in a stream, or over data about anyone else.

8. Third-party trademarks, and no affiliation

Product, brand, league, team and platform names shown on the Service, including Topps, Bowman, Panini, Upper Deck, Whatnot and eBay, are trademarks of their owners. We use them only to identify the products and platforms we describe. Cardonomics is not affiliated with, sponsored by or endorsed by any of them. Links to other sites are for convenience; we do not control those sites and are not responsible for them.

9. Information only: not financial advice

Everything on the Service is general information, not financial, investment, tax or legal advice, and not a recommendation to buy, sell or take part in anything. We are not a broker, dealer, appraiser or financial adviser.

Our figures come from live streams we observe and from prices, checklists, odds and release dates published by manufacturers and online shops and marketplaces. They are observations and calculations, not promises. They can be wrong, incomplete or out of date: capture misses streams, sources change or restate figures, and prices move after we read them. Published odds describe packs, not your chance of pulling anything. Check anything important before you spend money.

A break is a paid game of chance. What you receive depends on what is pulled, and many people get back less than they paid. Sports cards are a speculative collectible market. Only spend what you can afford to lose. Your decisions, and what comes of them, are your own.

10. Availability and changes to the Service

We work to keep the Service running, but we do not promise that it will be uninterrupted, error-free or available at any particular time. Data capture sometimes stops, sources sometimes fail, and the site goes down for maintenance and deploys. We may add, change, limit or remove features. If we remove a paid feature you rely on in a way that materially reduces your plan, you may cancel, and we will handle any refund fairly.

11. The Service is provided “as is”

To the fullest extent the law allows, the Service and all data are provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy and uninterrupted or error-free operation. Some places do not allow certain warranties to be excluded, so some of this may not apply to you.

12. Limitation of liability

To the fullest extent the law allows: (a) we are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost revenue, lost data, or money lost buying, selling or breaking cards or taking part in breaks, even if we were told such losses were possible; and (b) our total liability for all claims about the Service or these Terms is limited to the greater of the amount you paid us in the 12 months before the event giving rise to the claim, or US $100.

Nothing in these Terms limits liability that the law does not allow to be limited.

13. Indemnity

If someone brings a claim against us because of your breach of these Terms, your misuse of the Service, or your violation of the law or of someone else's rights, you agree to defend and indemnify us, and to cover reasonable costs, including attorneys' fees, to the extent the claim arises from what you did. We will tell you about the claim and may take part in the defence with lawyers of our choosing.

14. Ending your account

You can stop using the Service at any time, and delete your account from Settings → Your data. Deleting an account does not cancel a Stripe subscription by itself, so cancel first (section 4).

We may suspend or close your account, with or without notice, if you break these Terms, if a payment is charged back or fraudulent, if we are required to by law, or if your use puts the Service, other users or third parties at risk. Where it is reasonable we will tell you why. If we close a paid account without cause, we will refund the unused part of the current month.

Sections that by their nature should survive the end of your account survive it, including sections 6 to 9 and 11 to 19.

15. Governing law

These Terms are governed by the laws of the State of Alabama and applicable federal law, including the Federal Arbitration Act, without regard to conflict-of-laws rules. Subject to section 16, any claim that is not arbitrated will be brought only in the state or federal courts located in Alabama, and you and we consent to their jurisdiction. If you live outside the United States, mandatory consumer protections of the country where you live still apply to you.

16. Dispute resolution, arbitration and class action waiver

Please read this section carefully. It affects how disputes are resolved and your right to go to court.

Talk to us first

Before starting any formal proceeding, the person with the dispute agrees to send a written notice describing it and the remedy wanted, to [email protected] (for disputes with us) or to the email on your account (for disputes with you). Both sides will try in good faith to settle it within 60 days.

Binding individual arbitration

If the dispute is not settled within 60 days, you and we agree that any dispute, claim or controversy arising out of or relating to these Terms or the Service will be resolved by binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court. The arbitrator may award the same individual relief a court could. Arbitration may be held by video or phone, or in the county where you live. Payment of filing and arbitrator fees will follow the AAA's consumer rules.

No class actions

You and we may bring claims against each other only individually, and not as a plaintiff or class member in any class, collective, consolidated or representative proceeding. The arbitrator may not combine more than one person's claims. If this class action waiver is found unenforceable for a claim, that claim must be decided in court, not in arbitration.

Exceptions

Either side may bring an individual claim in small claims court if it qualifies. Either side may also ask a court for an injunction to stop infringement or misuse of intellectual property or unauthorised access to the Service.

Opting out

You can opt out of this arbitration agreement by emailing [email protected] within 30 days of first accepting these Terms, with the subject “Arbitration opt-out” and the email address on your account. Opting out does not affect anything else in these Terms.

17. Copyright complaints

We respect intellectual property rights. If you believe material on the Service infringes a copyright you own or control, send a notice to our designated agent under the Digital Millennium Copyright Act:

Email: [email protected] (subject: “Copyright notice”)
Mail: Copyright Agent, Powerhouse Holdings, LLC d/b/a Cardonomics, (postal address available from [email protected])

Your notice should include: your physical or electronic signature; identification of the copyrighted work; identification of the material you say is infringing, with enough detail for us to find it; your contact details; a statement that you believe in good faith the use is not authorised by the owner, its agent or the law; and a statement, under penalty of perjury, that the notice is accurate and that you are the owner or authorised to act for the owner. If material you posted was removed, you may send a counter-notice with the information the law requires. We may close the accounts of repeat infringers.

18. Changes to these Terms

We may update these Terms. When we do, we will change the version and date at the top of this page. If a change is material, we will tell you in advance by email or on the Service, and ask you to accept the new Terms before you continue using your account. Changes do not apply to a dispute already notified under section 16 before the change. If you do not agree to a change, stop using the Service and cancel any subscription before it takes effect.

19. General terms

Severability. If any part of these Terms is found unenforceable, the rest stays in effect, and that part will be enforced as far as the law allows, except as section 16 says about the class action waiver.

Entire agreement. These Terms, together with the Privacy Notice and any terms shown when you buy a plan, are the whole agreement between you and us about the Service, and replace any earlier agreement about it.

Other terms. If we do not enforce a right, we have not waived it. You may not transfer these Terms without our consent; we may transfer them as part of a merger, sale or reorganisation. Nothing in these Terms creates a partnership, agency or employment relationship. Neither side is responsible for delays caused by events beyond its reasonable control.
