These Terms of Service (the "Terms") are a binding agreement between you and Sync My Cards, LLC, a California limited liability company, 5737 Kanan Rd #832, Agoura Hills, CA 91301 ("Sync My Cards," "we," "us," or "our"). They govern your access to and use of syncmycards.com, its subdomains, our applications, our API, our Model Context Protocol server, and all related services (together, the "Service").

Our Privacy Policy describes how we handle personal information and is incorporated into these Terms by reference.

Section 19 covers how disputes are handled, including arbitration and a class action waiver. Please read it.

By creating an account, clicking to accept these Terms, or accessing or using the Service, you agree to be bound by them. If you do not agree, do not use the Service.

If you accept these Terms on behalf of a company, partnership, sole proprietorship or other entity, you represent that you have authority to bind that entity, and "you" refers to both you and that entity.

2. Eligibility

You must be at least 18 years old to use the Service. The Service is a business tool and is not directed to children. We do not knowingly permit accounts for anyone under 18, and we do not offer parent-managed or minor accounts of any kind.

You must not be located in, or a resident of, a country or region subject to comprehensive United States sanctions, and you must not appear on any United States government restricted-party list.

4. Your Account

You are responsible for the accuracy of your registration information, for keeping your credentials confidential, and for all activity that occurs under your Account, whether or not you authorized it. Notify us at support@syncmycards.com as soon as you learn of any unauthorized access.

Your plan may include team-member seats, shown at syncmycards.com/pricing. Each team member must use their own login and is bound by these Terms, and you are responsible for everything they do under your Account. You may not share one login between people, and you may not resell or provide access to anyone outside your business.

5. Subscriptions, fees and automatic renewal

5.1 Plans and fees

Paid plans are billed in advance at the price and interval shown at checkout. All fees are stated in U.S. dollars and are exclusive of taxes; you are responsible for any sales, use, VAT, GST or similar taxes, other than taxes on our income.

Subscription billing is processed by Stripe, Inc. We do not collect or store your full payment card details. By subscribing, you authorize us and our payment processor to charge your selected payment method for all fees as they become due.

5.2 Automatic renewal

YOUR SUBSCRIPTION RENEWS AUTOMATICALLY. Unless you cancel before the end of your then-current term, your Subscription will automatically renew for successive periods of the same length as the term you selected (for example, month to month for a monthly plan, or year to year for an annual plan), and your payment method will be charged the then-current price for that plan at the start of each renewal period, until you cancel.

At checkout we separately identify the auto-renewal terms and obtain your affirmative consent to them. We retain a record of that consent.

5.3 How to cancel

You may cancel at any time, online, from your Account settings, without calling or emailing us. Cancellation takes effect at the end of your current billing period. You keep access to paid features until then. We may present a retention or discount offer during the cancellation flow, but a clear cancellation control will always be available to you on the same screen.

You may also cancel by emailing support@syncmycards.com, but you are never required to do so.

5.4 Renewal reminders and change notices

We will send you a reminder at least once every twelve months stating that your Subscription renews automatically, the amount and frequency of the charges, and how to cancel.

If we change your price, or make a material change to the features of your plan, we will notify you by email at least seven and not more than thirty days before the change takes effect. If you do not want to continue on the new terms, cancel before the change takes effect.

5.5 Refunds

Except where a refund is required by applicable law, fees are non-refundable and we do not provide refunds or credits for partial billing periods, unused time, or periods in which you did not use the Service. We may issue a refund or credit in an individual case at our discretion; doing so does not oblige us to do so in any other case.

5.6 Free trials

Paid plans include a 30-day free trial on your first paid Subscription. Unless you cancel before the trial ends, your Subscription converts to the plan you selected and your payment method is charged the then-current price for that plan at the end of the trial, and on each renewal after that. We will email you before the first charge.

5.7 Non-payment

If a charge fails, we may retry it and may suspend or downgrade your Account until payment succeeds. You remain responsible for amounts owed.

6. Connected Platforms

6.1 Your authorization

The Service works by connecting to your accounts on Connected Platforms. When you link a Connected Platform, you authorize us to access, read, create, modify and delete data in that account to the extent needed to provide the features you have enabled, including creating and updating listings, adjusting prices and inventory quantities, and reading orders.

You represent that you own or are authorized to administer each Connected Platform account you link.

6.2 Connected Platform terms are yours to comply with

Each Connected Platform has its own terms, policies, fee schedules and listing rules. You are solely responsible for complying with them. Nothing in these Terms modifies your agreement with any Connected Platform, and we are not a party to it.

6.3 We do not control Connected Platforms

Connected Platforms may change, deprecate, rate-limit, suspend or revoke their APIs at any time, with or without notice, and may suspend or terminate your account with them for reasons that have nothing to do with us. We are not responsible for any Connected Platform's acts, omissions, API changes, downtime, policy enforcement, fee changes, or any suspension, restriction or termination of your account on that platform, including where it results from activity the Service performed under your authorization.

If a Connected Platform revokes or restricts our access, features that depend on it may stop working. That is not a breach of these Terms by us.

Back to top

7. Your responsibility for what gets published

This section matters more than any other section for how you should use the Service. Read it.

The Service automates the creation and updating of commercial listings on platforms where you are the seller of record. You, not Sync My Cards, are the seller. You are solely responsible for:

  • Verifying every listing after a sync, including titles, descriptions, images, item conditions, prices and inventory quantities.
  • Pricing decisions. Any price mapping, markup rule, currency conversion, rounding, or pricing suggestion the Service applies is a tool you configured. You are responsible for the resulting prices and for honoring, or declining to honor, any resulting sale.
  • Inventory accuracy and oversells. Syncing inventory across channels involves timing gaps. Two buyers on two platforms can purchase the same item before a quantity update propagates. You are responsible for handling oversells, cancellations, refunds and any platform penalties, defects or metrics impact that result.
  • Your listing content, including that it is accurate, not misleading, and does not infringe anyone's rights.
  • Legal compliance for your sales, including tax collection and remittance, consumer protection law, and any authentication, grading or provenance claims you make about a card.

We do not guarantee that any sync will be complete, timely, accurate or error-free. You should treat the Service as an aid to your operations, not as a substitute for reviewing what you have published for sale.

Back to top

8. Acceptable use

You will not:

  • Use the Service to list, sell or facilitate the sale of counterfeit, stolen, altered or misrepresented items, including trimmed, recolored or otherwise doctored cards presented as unaltered, or items with forged or misrepresented grading or authentication.
  • Circumvent, manipulate or artificially inflate any Connected Platform's fees, search ranking, metrics or policies.
  • Access the Service by any automated means other than our documented API or MCP Server, or exceed published rate limits.
  • Reverse engineer, decompile or attempt to derive the source code of the Service, except where that restriction is unenforceable under applicable law.
  • Copy, resell, sublicense or provide the Service to a third party as a service, or build a competing product using the Service or information obtained from it.
  • Probe, scan or test the vulnerability of the Service, or breach or circumvent any security or authentication measure.
  • Upload malware, or any content that is unlawful, infringing, defamatory or obscene.
  • Use the Service in violation of United States export control or sanctions laws.
  • Use the Service in a way that causes us to violate any Connected Platform's terms.

9. Your content and our license to use it

You retain all rights in your Merchant Data. You grant us a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, display, adapt and process your Merchant Data solely as needed to provide, secure, support and improve the Service, and to comply with law.

We do not use your Merchant Data or Connected Platform Data to train machine learning models.

We may generate and use aggregated, de-identified statistics about use of the Service that cannot reasonably be used to identify you, your business or your customers.

Back to top

10. Copyright and DMCA

We respect intellectual property rights. If you believe content on the Service infringes your copyright, send a notice containing the elements required by 17 U.S.C. § 512(c)(3) to:

Copyright Agent, Sync My Cards, LLC
5737 Kanan Rd #832, Agoura Hills, CA 91301
Email: support@syncmycards.com

We may remove allegedly infringing content and terminate the accounts of repeat infringers.

Back to top

11. Our intellectual property

The Service, including its software, APIs, user interfaces, documentation, and the Sync My Cards name and logo, is owned by us and protected by intellectual property law. Subject to these Terms and payment of applicable fees, we grant you a limited, revocable, non-exclusive, non-transferable right to access and use the Service for your internal business purposes. No other rights are granted.

Back to top

12. Feedback

If you send us ideas, suggestions or feature requests, you grant us an unrestricted, perpetual, royalty-free right to use them without obligation or compensation to you.

Back to top

13. AI features and the MCP Server

On eligible plans you may connect a third-party AI client to your Account through our MCP Server.

If you do, you acknowledge that:

  • You choose the AI client. When you connect one, your Account data is transmitted to that client and to the AI provider behind it, at your direction. From that point it is governed by that provider's terms and privacy policy, not ours.
  • AI output can be wrong. Any output, recommendation or action produced through an AI client is not verified by us. You are responsible for reviewing it before acting, and Section 7 applies in full to anything an AI client causes to be published.
  • You are responsible for what the AI client does under your credentials. Actions taken through your connected client are treated as actions taken by you.
  • We may log MCP requests for security, abuse prevention and support.

We may add, change or remove AI features, and may suspend MCP access if we reasonably believe it is being used unsafely or abusively.

Back to top

14. Availability and support

We aim to keep the Service available but do not commit to any uptime level. The Service is not provided with a service level agreement. We may perform maintenance, and may modify, add to or discontinue features at any time. Where we discontinue a material feature you are paying for, we will give you reasonable notice.

Support is provided at the level described for your plan, by email at support@syncmycards.com.

Back to top

15. Suspension and termination

By you. Cancel at any time under Section 5.3. You may delete your Account by emailing privacy@syncmycards.com from the email address on the Account.

By us. We may suspend or terminate your access, with or without notice, if you materially breach these Terms, if your use creates a security, legal or platform-compliance risk, if you fail to pay, if a Connected Platform requires it, or if required by law. Where practical we will notify you first and give you an opportunity to cure.

On termination. Your right to use the Service ends, and we will delete or de-identify your Merchant Data in accordance with the Privacy Policy and Exhibit A. You remain responsible for fees accrued before termination. We do not restore listings, pricing or inventory state on Connected Platforms after termination. Export anything you need before you cancel.

Sections 7, 9, 11, 12, 16, 17, 18, 19, 20 and 22 survive termination.

Back to top

16. Third-party services

The Service may link to or interoperate with third-party services beyond Connected Platforms, including payment processors and shipping providers. Those services are governed by their own terms. We do not endorse them and are not responsible for them.

Back to top

17. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED AND STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY AND NON-INFRINGEMENT.

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE; THAT ANY SYNC WILL BE COMPLETE, TIMELY OR ACCURATE; THAT PRICES OR INVENTORY QUANTITIES WILL BE CORRECTLY PUBLISHED OR UPDATED ON ANY CONNECTED PLATFORM; OR THAT USE OF THE SERVICE WILL NOT RESULT IN ACTION BY A CONNECTED PLATFORM AGAINST YOUR ACCOUNT.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.

Back to top

18. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

(a) No indirect damages. NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST SALES, LOST BUSINESS OPPORTUNITY, LOSS OF GOODWILL, LOSS OR CORRUPTION OF DATA, OR COST OF SUBSTITUTE SERVICES, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

(b) Cap. OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (i) THE TOTAL FEES YOU PAID US IN THE TWELVE MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (ii) ONE HUNDRED U.S. DOLLARS ($100).

(c) Specifically excluded. THE LIMITS IN (a) AND (b) APPLY TO, AMONG OTHER THINGS, CLAIMS ARISING FROM INCORRECT PRICES OR INVENTORY QUANTITIES PUBLISHED TO A CONNECTED PLATFORM; OVERSOLD ITEMS; SALES YOU WERE REQUIRED TO HONOR AT AN UNINTENDED PRICE; PLATFORM FEES, DEFECTS, METRIC IMPACTS, RESTRICTIONS OR ACCOUNT SUSPENSIONS; SYNC FAILURES, DELAYS OR DUPLICATION; AND OUTPUT OR ACTIONS OF ANY AI CLIENT CONNECTED THROUGH THE MCP SERVER.

(d) These limits apply even if a limited remedy fails of its essential purpose, and are an essential basis of the bargain between us. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you. Nothing here limits liability that cannot be limited by law, including for fraud or willful misconduct.

19. Dispute resolution and arbitration

Please read this section carefully. It affects your legal rights. It requires most disputes between you and Sync My Cards to be resolved by binding individual arbitration rather than in court, which means you give up your right to a jury trial and your right to participate in a class action. You may opt out of arbitration within 30 days of first accepting these Terms under Section 19.5.

19.1 Informal resolution first

Before filing a claim, you agree to try to resolve it informally by emailing a description of the dispute to legal@syncmycards.com. Both parties will attempt in good faith to resolve it for 60 days before starting a formal proceeding.

19.2 Binding individual arbitration

If informal resolution fails, any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules, before a single arbitrator. Arbitration will take place in Los Angeles County, California, or by videoconference or on documents at your election. The Federal Arbitration Act governs the interpretation and enforcement of this section.

19.3 Class action waiver

YOU AND SYNC MY CARDS AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims or preside over any form of representative proceeding. If this waiver is found unenforceable as to a particular claim, that claim must proceed in court and the rest of this Section 19 still applies to all other claims.

19.4 Exceptions

Either party may bring an individual claim in small claims court, and either party may seek injunctive relief in court to protect its intellectual property or to stop unauthorized access to the Service.

19.5 Opt-out

You may opt out of Section 19.2 and 19.3 by emailing legal@syncmycards.com within 30 days of first accepting these Terms, stating your name, the email on your Account, and that you are opting out of arbitration. Opting out does not affect any other part of these Terms.

19.6 Time limit

Any claim must be brought within one year after it arises, or it is permanently barred, to the extent permitted by law.

Back to top

20. Governing law and venue

These Terms are governed by the laws of the State of California, excluding its conflict-of-laws rules. For any dispute not subject to arbitration, you and we consent to the exclusive jurisdiction of the state and federal courts located in Los Angeles County, California, and waive any objection to venue there.

Back to top

21. Changes to these Terms

We may update these Terms. We will post the updated version with a new effective date and, for material changes, notify you by email or in-app notice at least 30 days before they take effect. Material changes do not apply retroactively.

If you continue to use the Service after the effective date, you accept the updated Terms. If you do not accept them, cancel before that date. Changes to Section 19 will not apply to any dispute of which we had actual notice before the change.

We maintain archived versions of these Terms at syncmycards.com/terms/archive.

Back to top

22. General

  • Entire agreement. These Terms, the Privacy Policy and Exhibit A are the entire agreement between us regarding the Service and supersede all prior agreements and understandings.
  • Severability. If a provision is unenforceable, it is modified to the minimum extent necessary or severed, and the rest remains in effect.
  • No waiver. Failure to enforce a provision is not a waiver of it.
  • Assignment. You may not assign these Terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition or sale of assets.
  • Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, including acts of God, war, civil unrest, labor action, internet or utility failure, or the acts of a Connected Platform or hosting provider.
  • Relationship. Nothing here creates a partnership, joint venture, agency or employment relationship.
  • Notices. We may give notice by email to the address on your Account or by posting in the Service. Notices to us go to legal@syncmycards.com and to the mailing address above.
  • No third-party beneficiaries. Except as stated in Exhibit A, these Terms create no third-party beneficiary rights.
  • Export. You will comply with all applicable export control and sanctions laws.
  • Headings. Headings are for convenience only.

Exhibit A: Data Processing Addendum

This Data Processing Addendum ("DPA") forms part of the Terms and applies where you are a controller of personal data and Sync My Cards processes that personal data on your behalf, including personal data contained in Connected Platform Data such as order shipping details.

A.1 Roles. You are the controller (or, under CCPA, the business). Sync My Cards is the processor (or, under CCPA, the service provider). Where you are yourself a processor for a third party, Sync My Cards is a subprocessor.

A.2 Subject matter and duration. Processing is for the term of your Account plus the retention periods in the Privacy Policy.

A.3 Nature and purpose. Providing the inventory sync, order sync, listing management and multi-marketplace features you enable, plus security, abuse prevention, support and legal compliance.

A.4 Categories of data subjects. Your personnel, and the customers of your Connected Platform stores whose order data is synced.

A.5 Categories of personal data. Names, email addresses, postal and shipping addresses, order details and order-related identifiers. We do not require or knowingly process special category data, government identifiers, or payment card numbers.

A.6 Our obligations. Sync My Cards will:

  1. Process personal data only on your documented instructions, which these Terms and your configuration of the Service constitute, and not for our own purposes. We will not sell or share your personal data, and will not use it for cross-context behavioral advertising or to train machine learning models.
  2. Implement appropriate technical and organizational security measures, including encryption in transit and at rest, role-based access restricted to personnel with a need to know, and logging of access to personal data.
  3. Ensure personnel with access are bound by confidentiality obligations.
  4. Notify you without undue delay, and in any event within 72 hours, after becoming aware of a personal data breach affecting your personal data, with the information reasonably available to us.
  5. Assist you, at your reasonable expense, in responding to data subject requests and in carrying out data protection impact assessments and consultations with supervisory authorities.
  6. On termination, delete or return your personal data within the periods stated in the Privacy Policy, except where retention is required by law.
  7. Make available information reasonably necessary to demonstrate compliance with this DPA. No more than once per year, we will respond to a reasonable written security questionnaire and provide the security documentation we maintain. An audit or inspection is available only where a supervisory authority requires one, subject to reasonable confidentiality and scheduling terms.

A.7 Your obligations. You represent that you have a lawful basis and all necessary notices and consents to provide the personal data you submit or authorize us to access, that your instructions comply with applicable data protection law, and that you will not submit personal data outside the categories in A.5.

A.8 Subprocessors. You authorize the use of subprocessors listed in Exhibit B. We remain responsible for their performance and will impose data protection obligations no less protective than this DPA. We will give you at least 30 days notice before adding or replacing a subprocessor, by email to the address on your Account. If you reasonably object on data protection grounds, you may terminate the affected Service without penalty for the unused portion of your prepaid term.

A.9 International transfers. Where personal data is transferred from the EEA, the UK or Switzerland to a country without an adequacy decision, the transfer is governed by the EU Standard Contractual Clauses (Commission Decision 2021/914), Module Two (controller to processor) or Module Three (processor to processor) as applicable, and the UK International Data Transfer Addendum for UK transfers, each incorporated by reference with Sync My Cards as data importer, this DPA supplying the required annex information, and the governing law and forum being those of Ireland.

A.10 CCPA. Sync My Cards is a service provider and will not retain, use or disclose personal information except to perform the Service, will not sell or share it, will not combine it with personal information from other sources except as permitted, and will comply with applicable CCPA obligations. We will notify you if we determine we can no longer meet these obligations.

A.11 Order of precedence. In case of conflict, this DPA controls over the rest of the Terms as to the processing of personal data.
