Terms of Service

1. Acceptance of Terms

By downloading, installing, accessing, or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not use the Service.

If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization, and “you” refers to that organization.

2. Eligibility

RareBlink does not impose its own minimum-age requirement beyond what applicable law requires. The RareBlink app carries a 13+ age rating in the Apple App Store (consistent with comparable marketplace apps, including eBay’s own app), which Apple enforces at the device level through its parental-control and Screen Time mechanisms. The Service is not directed to children under 13, and we do not knowingly collect personal information from children under 13 (see our Privacy Policy, Section 8). Any purchase of a card or item occurs exclusively on a third-party marketplace (e.g., eBay), which imposes and enforces its own age and account requirements — eBay requires account holders to be at least 18. Subscriptions are billed through your Apple ID, which is subject to Apple’s own age, consent, and family-account rules.

If you are under the age of majority in your jurisdiction, you may use the Service only with the involvement and consent of a parent or legal guardian who holds the underlying Apple ID and payment method.

You further represent that you are not barred from using the Service under the laws of the United States or any other applicable jurisdiction, including export control and sanctions laws (see Section 19.6).

3. The Service

RareBlink is a marketplace-intelligence tool for trading cards and collectibles. RareBlink monitors third-party marketplace listings (initially eBay), identifies cards via automated and AI-assisted means (“Scan”), estimates market value (“RareBlink Value”) from third-party sales-comparable data, generates a relative opportunity score (“Blink Score”) for individual listings (“Blinks”), and allows you to configure alert criteria (“Watches”) for push notifications when a qualifying Blink is found.

RareBlink is not a marketplace, retailer, escrow service, payment processor, or auction platform, and no purchase, sale, bid, or transaction of any kind occurs within the Service. Tapping “View on eBay” (or a similar call-to-action for another supported marketplace) opens or deep-links to that third-party marketplace’s own website or app. Any transaction you enter into occurs solely between you and the third-party seller and/or marketplace, and is governed entirely by that marketplace’s own terms of service, policies, and buyer protections — not by these Terms. See Section 10 (Disclaimers) and Section 11 (Affiliate Disclosure) below.

4. Accounts

No account is required to use the free tier of the Service. Free-tier usage (browsing Blinks, a limited number of Watches, and a limited number of Scans) is tied to an anonymous, device-scoped identifier rather than a personal account.

You may optionally create an account, via Sign in with Apple or Google (through our authentication provider, Supabase), to (a) sync your data across devices, (b) subscribe to a paid tier, or (c) access other account-gated features. If you create an account, you agree to:

• provide accurate information (limited to the name and email address made available by the sign-in provider);
• keep your login credentials confidential and secure;
• notify us promptly of any unauthorized use of your account; and
• accept responsibility for all activity that occurs under your account.

We are not liable for any loss or damage arising from your failure to safeguard your account credentials or device.

5. License to Use the App

Subject to your compliance with these Terms, RareBlink grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use the Service on devices you own or control, solely for your personal, non-commercial use.

All rights not expressly granted to you in these Terms are reserved by RareBlink and its licensors.

6. Acceptable Use

You agree that you will not, and will not attempt to:

• scrape, crawl, harvest, mine, or otherwise systematically extract data from the Service by any automated means (bots, scripts, spiders) without our prior written consent;
• reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code, underlying algorithms, scoring formulas, or data models of the Service;
• copy, resell, sublicense, rent, lease, redistribute, or otherwise commercially exploit RareBlink Value figures, Blink Scores, comp data, or any other data or content obtained from the Service, in whole or in part, whether or not for a fee;
• use the Service to build or train a competing product, dataset, or machine-learning model;
• circumvent, disable, or interfere with any rate limit, authentication mechanism, security feature, or usage quota of the Service;
• misrepresent your identity, impersonate any person or entity, or use the Service to harass, defraud, or deceive any seller, buyer, or other user;
• use the Service for any automated purchasing, bidding, sniping, or checkout activity (RareBlink contains no such functionality and none may be layered on top of it via unauthorized integrations);
• upload, transmit, or Scan any content that infringes a third party’s intellectual property rights, violates any law, or that you do not have the right to submit;
• upload malicious code, or interfere with or disrupt the integrity or performance of the Service or its underlying infrastructure; or
• use the Service in violation of eBay’s, Apple’s, or any other integrated third party’s own terms of service.

We may investigate and take appropriate action against anyone who violates this section, including suspending or terminating access, and, where warranted, reporting to law enforcement.

7. Subscriptions, Billing, and Apple In-App Purchases

Certain features of the Service (currently marketed as the “Pro” tier) are offered on a paid, auto-renewing subscription basis (each a “Subscription”). Subscriptions on iOS are sold and billed exclusively through Apple’s In-App Purchase system, and the following applies:

• Payment. Payment will be charged to your Apple ID account at confirmation of purchase.
• Auto-renewal. Your Subscription automatically renews for the same subscription period unless you turn off auto-renew at least 24 hours before the end of the current period, in the App Store account settings on your device.
• Price changes. We may change Subscription pricing from time to time; any price change will be presented through Apple’s standard notice mechanisms before it takes effect for you, consistent with Apple’s guidelines.
• Free trials. If a free trial period is offered, your Subscription converts to a paid Subscription automatically at the end of the trial unless you cancel before it ends.
• Cancellation. You may cancel your Subscription at any time through your Apple ID account settings (Settings → [your name] → Subscriptions on iOS). Cancellation takes effect at the end of the current billing period; you will retain access to paid features through that period.
• Refunds. All billing is handled by Apple, and all refund requests must be submitted to Apple, not RareBlink, via reportaproblem.apple.com or your device’s purchase history. Refunds are granted or denied solely at Apple’s discretion and under Apple’s own refund policies; RareBlink has no ability to process refunds directly and cannot guarantee any particular refund outcome.
• What a Subscription is (and isn’t). A paid Subscription unlocks features of the Service itself (e.g., faster/broader Blink Alerts, additional Watches, expanded Scans). It does not purchase, reserve, or guarantee any card, listing, or item on any third-party marketplace, and it does not entitle you to any refund, credit, or compensation based on the outcome of any purchase you make on a third-party marketplace.
• Web checkout (if offered). If we ever offer subscription purchase through a non-Apple checkout (e.g., a web-based payment processor), separate billing terms specific to that checkout method will be presented to you at the time of purchase and will govern that transaction.

8. User Content

“User Content” means any content you submit to the Service, including photographs you take or upload for the Scan feature, Watch criteria you configure, and any feedback, ratings, or correction submissions you provide (e.g., flagging a Blink as accurate/inaccurate).

By submitting User Content, you grant RareBlink a worldwide, non-exclusive, royalty-free, sublicensable license to host, store, reproduce, transmit, and process that User Content solely for the purposes of (a) operating and improving the Service (including sending Scan photographs to third-party AI/vision and card-database providers for identification, valuation, and comp-matching purposes), (b) diagnosing and fixing errors, and (c) internal analytics to improve the accuracy of identification and scoring. See our Privacy Policy for how Scan photographs and other data are handled by us and by our processors.

You represent that you own or have the necessary rights to any User Content you submit, and that submitting it does not infringe any third party’s rights. We may, but are not obligated to, review, moderate, or remove User Content at our discretion.

9. Intellectual Property Ownership

The Service, including its software, design, user interface, “Blink,” “Blink Score,” “RareBlink Value,” “Watch,” “RareBlink Scan,” and other RareBlink branding, trademarks, logos, text, graphics, and underlying scoring methodology, is owned by RareBlink and/or its licensors and is protected by copyright, trademark, trade secret, and other intellectual property laws. Nothing in these Terms transfers any such rights to you beyond the limited license in Section 5.

Third-party marks referenced within the Service (including eBay, PSA, BGS, CGC, SGC, Topps, Panini, Pokémon, and other manufacturer, grading, or marketplace names and logos) are the property of their respective owners and are used solely for identification and informational purposes. See Section 10.7 for our disclaimer of affiliation with these entities.

11. eBay Affiliate Disclosure

RareBlink participates in the eBay Partner Network (EPN), an affiliate advertising program. When you tap “View on eBay” (or a similar link-out) and are directed to eBay, RareBlink may earn a referral commission on qualifying purchases you or others make on eBay within the applicable attribution window, at no additional cost to you. This commission does not influence, and is not a factor in, how Blinks are identified, scored, or ranked. See Section 12 for how EPN link-outs may use tracking cookies.

12. Third-Party Links and Services

The Service links out to and relies on third-party services (including eBay, Apple, and card-pricing data providers) that RareBlink does not own, control, or operate. RareBlink is not responsible for the content, accuracy, availability, security practices, or terms of any third-party website, marketplace, or service. Your use of any third-party service is governed solely by that third party’s own terms and privacy policy.

14. Indemnification

You agree to defend, indemnify, and hold harmless RareBlink (Nickolas Parker) and its contractors, agents, and licensors from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use or misuse of the Service; (b) any purchase or transaction you enter into with a third-party seller or marketplace; (c) your violation of these Terms; (d) your violation of any third party’s rights, including intellectual property or privacy rights; or (e) User Content you submit.

15. Term and Termination

These Terms remain in effect while you use the Service. We may suspend or terminate your access to the Service (or any part of it), with or without notice, at any time, including for suspected violation of Section 6 (Acceptable Use) or for operational or legal reasons. You may stop using the Service, and delete your account and associated data (see Privacy Policy for the account-deletion mechanism required by Apple), at any time.

Sections 8–14, 17, and 19 survive termination of these Terms, along with any other provision that by its nature should survive.

Terminating your use of the Service does not automatically cancel an active Apple Subscription; Subscriptions must be canceled separately through your Apple ID account settings (Section 7).

16. Governing Law and Dispute Resolution

16.1 Governing law.

These Terms are governed by the laws of the State of North Carolina, without regard to its conflict-of-laws principles, and without regard to the United Nations Convention on Contracts for the International Sale of Goods.

16.2 Venue.

Subject to Section 16.3 (Arbitration, if adopted), you and RareBlink agree that any dispute arising out of or related to these Terms or the Service will be brought exclusively in the state or federal courts located in North Carolina, and you consent to personal jurisdiction there.

16.3 Arbitration (optional clause — attorney decision required).

17. Changes to These Terms

We may modify these Terms from time to time. If we make material changes, we will provide notice (for example, through the app, by posting an updated “Last Updated” date above, or by email if you have an account). Continued use of the Service after changes take effect constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, you must stop using the Service.

18. Miscellaneous

18.1 Entire agreement.

These Terms, together with the Privacy Policy, constitute the entire agreement between you and RareBlink regarding the Service and supersede any prior agreements.

18.2 Severability.

If any provision of these Terms is held unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force.

18.3 No waiver.

Our failure to enforce any provision of these Terms is not a waiver of our right to do so later.

18.4 Assignment.

You may not assign these Terms without our prior written consent. We may assign these Terms freely, including in connection with a merger, acquisition, or sale of assets.

18.5 Force majeure.

RareBlink is not liable for any failure or delay in performance resulting from causes beyond its reasonable control, including third-party API outages (e.g., eBay, Apple, Supabase, Vercel, CardSight, OpenAI), internet or infrastructure failures, or acts of God.

18.6 Export control / sanctions.

You may not use the Service if you are located in a country subject to a U.S. government embargo, or that has been designated by the U.S. government as a “terrorist supporting” country, or if you are listed on any U.S. government list of prohibited or restricted parties.

18.7 Apple as a third-party beneficiary.

You acknowledge that these Terms are between you and RareBlink only, not with Apple, and Apple is not responsible for the Service or its content. Apple has no obligation to furnish any maintenance or support for the Service. In the event of any failure of the Service to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the Service to you; to the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the Service. Apple is not responsible for addressing any claims by you or any third party relating to the Service, including but not limited to product liability claims, any claim that the Service fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection or similar legislation. Apple is not responsible for the investigation, defense, settlement, and discharge of any third-party claim that the Service infringes that third party’s intellectual property rights. You agree to comply with any applicable third-party terms when using the Service. Apple, and Apple’s subsidiaries, are third-party beneficiaries of these Terms, and upon your acceptance, Apple has the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
