Terms of Use

Effective date: January 20, 2026

These Terms of Use (“Terms”) govern your access to and use of the CheckCOA website, apps, and related services (collectively, the “Service”). The Service is operated by CheckCOA (“CheckCOA”, “we”, “us”, “our”). By using the Service, you agree to these Terms.

1. The Service (what we do)

CheckCOA is a verification aggregator for collectibles certificates (COA/LOA) and grading certifications. We help you retrieve and view certificate information from supported third-party providers in a structured, easy-to-read format.

Important: CheckCOA does not authenticate items, issue COAs/LOAs, grade collectibles, or provide appraisal/valuation services.

2. Non-Affiliation & Third-Party Data Disclaimer

CheckCOA is not affiliated with, endorsed by, sponsored by, or officially connected to PSA, Beckett, CGC, SGC, TAG, Wata, Fanatics, Upper Deck, or any other authentication/grading provider (each a “Provider”).

All Provider names, trademarks, logos, and related marks are the property of their respective owners.

The Service displays information obtained from Providers’ official sources (e.g., public databases, pages, APIs, or other official endpoints), without altering the meaning of the underlying data.

Providers are solely responsible for the accuracy, completeness, availability, and timeliness of their data. CheckCOA does not guarantee Provider results and is not liable for errors, omissions, or outages originating from Providers.

3. Eligibility

You must be at least 16 years old (or the age of digital consent in your region) to use the Service. If you use the Service on behalf of an organization, you represent you have authority to bind it.

4. Accounts & Authentication

You can create an account using Google sign-in or email/password. Authentication is handled by Supabase Auth.

Passwords are hashed and are never stored in plain text.

You are responsible for maintaining the confidentiality of your account and for all activity under your account.

5. Verification methods & usage types (AI vs Manual)

CheckCOA may offer different scan/check types that consume different quotas/credits:

  • AI Scans: checks that use text recognition (OCR) to extract certificate numbers from images/camera input.
  • Manual Checks: any check without OCR, including QR code scanning, paste-from-clipboard, manual typing, or other non-OCR methods.

6. Plans, quotas, credits, and one-time packs

The Service may include free and paid plans with monthly/annual quotas for AI Scans and Manual Checks. We may also offer one-time packs of checks that do not expire unless explicitly stated at checkout.

If you reach your quota:

  • the relevant scan/check type may be paused until the next billing cycle, or
  • you can upgrade your plan and/or purchase a one-time pack (if available).

We may change plans, quotas, or pricing prospectively. Any changes will apply at renewal or as otherwise required by law.

7. Payments, billing, and renewals

Payments are processed by Stripe (our payment processor). CheckCOA does not store full payment card details.

Subscriptions renew automatically until cancelled. You can cancel anytime via your account billing page; cancellation stops future renewals (you keep access until the end of the current paid period unless stated otherwise).

Refunds: Unless required by law, fees are non-refundable. We may issue refunds at our discretion (e.g., duplicate charge, technical failure clearly attributable to CheckCOA). Provider outages typically do not qualify.

8. Acceptable use

You agree not to:

  • use the Service to break laws or violate Provider terms;
  • attempt to scrape, reverse-engineer, abuse, overload, or bypass limits/security;
  • submit malicious content or interfere with the Service;
  • use the Service for misleading claims (e.g., “CheckCOA authenticated this item”).

9. User content (your uploads)

You may upload images, notes, prices, tags, and collection metadata (“User Content”). You retain ownership of your User Content.

You grant CheckCOA a limited license to host, store, process, and display your User Content solely to operate and improve the Service.

10. Availability & Provider access

Providers may block traffic, rate-limit, change formats, or restrict access in certain regions. CheckCOA may use server-side retrieval to display official data where possible, but we cannot guarantee access for every Provider, region, or time.

11. Intellectual property

The Service, including software, design, and content (excluding User Content and Provider marks), is owned by CheckCOA and protected by law.

12. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY OF THIRD-PARTY DATA. CHECKCOA DOES NOT WARRANT THAT RESULTS WILL BE ERROR-FREE OR THAT PROVIDER DATA WILL BE AVAILABLE.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CHECKCOA WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE OR PROVIDER DATA.

14. Indemnification

You agree to indemnify and hold harmless CheckCOA from claims arising out of your use of the Service, your User Content, or your violation of these Terms.

15. Changes to these Terms

We may update these Terms from time to time. We’ll update the “Effective date” and may notify you of material changes.
