Birth date handling
We designed this calculator so your birth date can be processed in your browser. We do not store your birth date in the first version of the site.
Analytics
We use Google Analytics 4 and Microsoft Clarity to understand page views, interaction patterns, scroll depth, clicks, device/browser information, referrers, and similar website usage signals. These tools help us improve the calculator experience and may use cookies or similar technologies. We do not send your full birth date to these analytics providers.
Affiliate links
If affiliate links are added later, they will be disclosed near relevant links and may send referral data to the partner site.
