DMCA & Copyright Policy

Effective July 29, 2026

Professor Lockin respects intellectual-property rights and expects the same of its users and authors (see the Content Policy). We respond to notices of alleged copyright infringement that comply with the Digital Millennium Copyright Act (17 U.S.C. § 512) as described below.

1. Filing a takedown notice

If you believe content on Professor Lockin infringes your copyright (this includes certification vendors whose exam content has been reproduced), send a written notice to our designated agent containing all of the following:

  1. identification of the copyrighted work you claim is infringed (or a representative list);
  2. identification of the infringing material and where it is on the Service — a direct URL to the guide, section, or deck is best;
  3. your name, mailing address, telephone number, and email address;
  4. a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law;
  5. a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorized to act for the owner; and
  6. your physical or electronic signature.

On receiving a valid notice we will remove or disable access to the material promptly, notify the user who posted it, and record the strike under our repeat-infringer policy.

2. Designated agent

Our Copyright Office designated-agent registration is in progress. Until it completes, send notices by email to ProfessorLockin@gmail.com with the subject line “DMCA notice” — we review every notice under the process described on this page.

3. Counter-notice

If your content was removed and you believe that was a mistake or misidentification, you may send our designated agent a written counter-notice containing:

  1. identification of the removed material and where it appeared before removal;
  2. a statement, under penalty of perjury, that you have a good-faith belief the material was removed as a result of mistake or misidentification;
  3. your name, address, and telephone number, and a statement that you consent to the jurisdiction of the federal district court for your address (or, if outside the US, any judicial district in which we may be found) and that you will accept service of process from the person who filed the original notice; and
  4. your physical or electronic signature.

Unless the original claimant notifies us within 10–14 business days that they have filed a court action, we may restore the removed material.

4. Repeat infringers

We terminate the accounts of users who repeatedly infringe copyright, and we may withhold marketplace earnings attributable to infringing content as described in the Author Agreement.

5. Misrepresentation

Under 17 U.S.C. § 512(f), anyone who knowingly and materially misrepresents that material is infringing — or that it was removed by mistake — may be liable for damages, including costs and attorneys’ fees. Don’t file false notices.
