Today this website shows no ads and has no affiliate links.
To keep the encyclopedia free, we may later add a shop, affiliate links or ads. If we do, these rules will always apply:
- Health information is written first and is never changed to sell something.
- Commercial content is clearly labelled and appears only in grown-up sections, never in the kids’ parts or quizzes.
- Affiliate links are marked as sponsored. We may earn a small commission, at no extra cost to you.
- No personalised advertising for children, and no ads on quiz or “My garden” pages.
- We never sell products for children, and we never suggest that a supplement replaces food, sleep, play or medical care.
