Your Privacy Choices
Effective November 11, 2026
Analytics
Product analytics, through PostHog and Google Analytics, runs only if you allow it. Allowing or rejecting it changes nothing about the calculator. Your choice is saved in this browser for 180 days, and a Global Privacy Control or Do Not Track signal keeps analytics off. Error reports, which contain no IP address or personal content, are a necessary part of running the Service and are not affected. Withdrawing stops Google Analytics at once and deletes its cookies.
Your date of birth and name
The date you enter in the calculator stays in your browser and is never sent to us. Reloading or leaving the page clears it. If you save your chart to an account, your name and date of birth are kept encrypted with it: in your account you can download your account data or delete your account.
Other requests
