What is available today
The reviewed calculators and their on-page previews work without payment details or advertising action. Private report pages, accounts, checkout, and exports are not part of the current public service.
Advertising is separate from results
Contextual advertising may appear on eligible editorial pages, but viewing or interacting with an ad never unlocks a result. Ads do not alter the calculation, score, interpretation rules, or result order.
Not available in this review version
The current site does not offer payment, account access, saved reports, email delivery, or PDF export. Any future service must publish its data handling, price, delivery, and consumer terms before it is activated.
