What sits behind an OpponentBook article.
OpponentBook is responsible for the articles published here. We want readers to be able to distinguish a study's finding, a practical suggestion and a product example.
Follow the evidence
Research claims link to primary studies or their institutional records where available. We describe what was measured and the limits of applying it to another sport or setting. A suggested note-taking routine is not a validated intervention unless a cited study actually tested it.
Write for the language
Each language edition is written and reviewed from shared facts, with its own headings, examples and structure. AI may assist writing and review. OpponentBook remains responsible for publication.
Checks and updates
Statements about what OpponentBook does are checked against the app itself, not only against its descriptions. Every language edition also goes through a separate review pass, independent of whoever wrote it. When we revise an article substantially, the date at the top of the page shows when.
Examples and corrections
Invented match notes and demo screens are labeled as examples. They are not testimonials or evidence that the app improves results. Product details can change. To report an error or an outdated statement, email support@opponentbook.com with the page and the passage concerned.
