# How our baby tools work
   
Verdict
 
Tools on this site run in your browser from published ranges — TOG maps, packing lists, legal categories. They are not medical devices and they do not fetch live shop prices. If a tool cannot see your room temperature, it should tell you to measure, not guess. Skip tools that would replace your midwife or installer.
    
Each tool ships a static HTML answer: a table or a checklist that does not need a click. JavaScript may personalise; it may not be the only copy of the advice.

No runtime price API. No third-party widget host. No claim that a calculator is a medical device. If a tool cannot run, we take the advert down.
