Editorial Policy

Our goal is simple: be the most accurate, least cluttered source on caffeine and sleep. Here’s how we keep it that way.

Accuracy first

Every caffeine value and claim traces to a primary source — manufacturer labels, USDA FoodData Central, FDA/EFSA guidance, or peer-reviewed research. We cite them on the page. Where evidence is mixed, we say so rather than pick a tidy answer.

How we write

• Plain language, no scare tactics, no “miracle” framing.
• The calculator’s math is the same engine described in our methodology — we don’t fudge numbers for a cleaner story.
• Author and reviewer are named on every guide, with the last-updated date.

Independence

We make money from the app, not from ads or affiliate links on drinks. No brand pays for a placement, a caffeine number, or a favorable review.
