Editorial Policy
PortionPal Food Calculators is responsible for the calculator logic and guidance published on this website.
What we publish
We publish interactive food-quantity calculators and practical planning guides. A page must have a distinct purpose, transparent assumptions, useful outputs and contextual links before it is eligible for indexing.
Sources and claims
We prefer primary sources for food-safety claims and link them beside the relevant advice. We do not invent authors, credentials, ratings, reviews, usage figures, testimonials or update dates.
Calculator changes
Formula changes must state the assumption and pass automated tests. Content and calculator configuration must describe the same food, event and units.
Corrections
Reports are reviewed against the formula, page copy and source material. Material corrections update the page’s reviewed date; routine deployments do not. Report an issue.
