DMCA, takedown and corrections

Three separate processes live on this page, because three different kinds of request arrive and they deserve different handling.

1. Copyright — notice and takedown

If you believe material on this site infringes your copyright, send a notice containing:

1. Identification of the copyrighted work claimed to be infringed.
2. The specific URL or URLs of the material you say is infringing, precisely enough for us to locate it.
3. Your name and an address at which we can respond.
4. A statement that you have a good-faith belief the use is not authorised by the copyright owner, its agent or the law.
5. A statement that the information in the notice is accurate and that you are the owner or authorised to act on the owner's behalf.
6. Your signature, electronic or physical.

Notices are addressed to the site operator via the postal address published in our domain registration record. We do not publish an email address on the site, because publishing one produces spam rather than correspondence. Complete notices are acted on promptly; incomplete ones will be returned with a note of what is missing. Counter-notices follow the same requirements and will be forwarded to the original complainant.

Substantially all textual content on this site is original to it and licensed CC BY-SA 4.0. Where a published trial or a certificate of analysis is discussed, we quote figures and cite the source; we do not reproduce copyrighted documents.

2. Factual corrections

We would much rather be corrected than be wrong, and a correction request is easier to satisfy than a takedown. Send the URL, the specific sentence, what is wrong with it, and ideally the source that settles it. Corrections to substantive factual errors are made and, where the error was material, noted on the page.

Things that are corrections: an incorrect trial figure, a wrong citation, a unit error in worked arithmetic, an out-of-date regulatory statement, a misattributed method parameter. Things that are not corrections: a disagreement with an interpretation, a dislike of a rating, or an assertion that a critical answer is unfair without saying which part of it is inaccurate.

3. Right of reply for named suppliers

All twenty suppliers in the vendor directory are named on this site without their involvement and without any payment in either direction. If you represent one of them, you may:

• Correct a factual error about your legal name, short code, city, establishment year or domain. These are business facts and we want them right. Send documentation and they will be fixed.
• Respond to a specific claim. If an independently obtained test result reported here is inaccurate, tell us why with reference to the lot and the method. A substantive response will be published alongside the claim.
• Supply better documentation. The single most effective way to improve a rating on this site is to publish lot-specific certificates carrying a method section and a quantified content figure. That is not a negotiating position; it is the criterion, and it is published.

What we will not do: remove a critical thread because it is critical, adjust a rating in exchange for anything, accept payment or product from a supplier, or treat a legal threat as a factual argument. Ratings and community assessments are opinion, clearly labelled as opinion, and they stay.

4. Personal data

Requests concerning personal data are handled under the privacy policy and use the same contact route.

5. What happens to reported content while we look

Content that is plausibly unlawful is made unavailable while assessed. Content that is merely disputed stays up, with the dispute noted where that is useful to a reader.
