We welcome corrections, data questions and partnership enquiries. Please use the channel that fits:

Corrections and factual errors

If a page states something the data does not support, email [email protected] with the page URL and the specific claim. Corrections that change a claim are logged on the changelog and the page is re-reviewed; the “Reviewed by” line on the page is updated.

Data and methodology questions

For questions about how a score is computed, what a “share of reported problems” means, or why a product is missing, start with Data Sources & Limitations and the scoring standards . If the answer is not there, email us with the question and the page you were reading.

Privacy, data removal and legal

• Privacy questions: see our Privacy Policy .
• If you are a brand or a rights holder and believe a page identifies your product unfairly, email us. We will review the underlying aggregate data and either correct the page or explain the method in writing.

Partnerships and licensing

We licence aggregated data and publish findings that media can cite. For data licensing, research collaboration or press enquiries, email [email protected] with a short description.

Response times

We are a small team and aim to respond within 5 business days. Correction requests that affect a published claim are prioritised.

Before you write

To help us help you faster:

• Include the page URL and, where relevant, the product ASIN.

Thank you for helping keep the data honest.
