Your calculator math stays in your browser.
The calculators do not need your identity, an account, or a server-side calculation to produce a result.
What leaves the browser?
Calculator math stays in the browser. No personally identifiable information is submitted: the tools do not ask for your name, email address, account number, or contact details.
What is included in a share URL?
Share URLs contain only the calculator assumptions you explicitly choose to share. Ordinary edits do not change the address. A share URL is created for copying only when you press the share control, and anyone you send it to can read those assumptions.
What can analytics receive?
Analytics never receives raw calculator inputs or outputs. The only allowed events are anonymous static identifiers such as which calculator was viewed, which named assumption was used, or whether a share, embed, methodology, or Smarter Way Wealth link was selected. Those events are delivered to PostHog, a product-analytics service, tagged with a random identifier that lives only for the current browser session — no cookies, no persistent identifier, no cross-site tracking. Page addresses attached to an event are stripped of query strings, so assumptions carried in a share URL never reach analytics.
