Terms of Service
Last updated: June 22, 2026
1. Agreement to these terms
Copyright Check ("Copyright Check," "we," "us," or "our") is a service operated by Whetstone Digital. These Terms of Service ("Terms") govern your access to and use of the copyrightcheck.app website and related tools (the "Service").
By accessing or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
2. What Copyright Check is, and what it is not
Copyright Check is an informational research tool. It cross-references song and catalog information you provide against publicly available data, including the U.S. Copyright Office public bulk dataset and public datasets that circulate among AI developers, and returns indicative results.
We are not a law firm, and we do not provide legal, financial, or professional advice. We are not affiliated with, endorsed by, or acting on behalf of the U.S. Copyright Office or any AI company. Using the Service does not create an attorney-client relationship or any professional-client relationship of any kind.
3. The data and its limits
Our results are derived from third-party and public data sources that may be incomplete, out of date, or contain errors. In particular:
- Copyright Office results come from a periodic public bulk dataset that covers a fixed date range and does not reflect registrations filed after that range or still being processed.
- The absence of a match does not mean a work is unregistered. A work may be registered under a different title, spelling, author or claimant name, or as part of a group or album registration.
- A reported match does not by itself prove ownership, registration status, or any legal right.
For any decision that matters, you should verify directly with the U.S. Copyright Office at copyright.gov and consult a qualified professional. You are solely responsible for any decision you make or action you take based on the Service.
4. The AI training-data check
The Service can indicate whether a song appears in certain public datasets that are known to circulate among AI developers. A match means only that a track with matching information appears in such a dataset. It is not a statement, claim, or assertion that any specific company, model, or product trained on, used, or copied your work, and it should not be represented as such.
Dataset membership is a signal, not proof. The actual training data of specific AI products is generally not public. You agree not to use the Service, or results from it, to make or publish factual claims that a particular company trained on a specific work.
5. No legal or professional advice
Nothing on the Service is legal, financial, tax, or other professional advice, and nothing on the Service should be relied on as such. Laws referenced on the Service, including any proposed legislation, are described for general information only, may change, and may not be law. Always consult your own qualified advisor before acting.
6. Accounts, plans, and payment
- Some features require an account. You are responsible for the accuracy of your account information and for activity under your account.
- Paid features are billed through our third-party payment processor. By purchasing, you authorize the applicable charge. One-time products (such as the Audit Pack) grant the access described at the time of purchase. Subscriptions renew automatically until cancelled.
- You may cancel a subscription at any time from your account; access continues through the end of the current billing period, and we do not provide prorated refunds for partial periods.
- One-time purchases are non-refundable once the associated audit or report has been generated, except where a refund is required by law.
- Prices and plans may change on a going-forward basis.
7. Acceptable use
You agree not to:
- scrape, crawl, bulk-download, resell, or redistribute the Service or its results except as expressly permitted;
- attempt to bypass rate limits, access controls, paywalls, or any security or usage restriction;
- use the Service to violate any law or the rights of others;
- interfere with or disrupt the integrity or performance of the Service.
We may suspend or terminate access that violates these Terms or that we reasonably believe is abusive.
8. Intellectual property
The Service, including its software, design, text, and branding, is owned by us or our licensors and is protected by law. You retain ownership of the catalog and search information you submit. You grant us a limited license to process that information solely to operate and provide the Service to you.
9. Disclaimer of warranties
THE SERVICE AND ALL RESULTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY THAT THE SERVICE OR ITS RESULTS WILL BE ACCURATE, COMPLETE, CURRENT, RELIABLE, OR UNINTERRUPTED.
10. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST DATA, OR LOST OPPORTUNITIES, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100). SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.
11. Indemnification
You agree to indemnify, defend, and hold harmless Whetstone Digital and its owners, operators, and affiliates from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the Service; (b) any decision you make or action you take, or fail to take, in reliance on the Service or its results; (c) any claim, statement, or representation you make based on the Service; (d) your violation of these Terms; or (e) your violation of any law or the rights of any third party.
12. Third-party services and links
The Service relies on third-party providers for authentication, payment processing, hosting, data storage, and email, and may link to third-party sites such as copyright.gov. We are not responsible for third-party services or content, and your use of them may be subject to their own terms.
13. Changes to the Service and these Terms
We may modify or discontinue the Service, and we may update these Terms, at any time. If we make material changes, we will update the date above. Your continued use of the Service after changes take effect means you accept the updated Terms.
14. Governing law and disputes
These Terms are governed by the laws of the State of [STATE: confirm your governing-law state], without regard to its conflict-of-laws rules. Before filing any formal dispute, you agree to first contact us and attempt to resolve the matter informally. Any dispute that cannot be resolved informally will be subject to the exclusive jurisdiction of the state and federal courts located in that state, unless applicable law provides otherwise.
