Privacy Policy

The public site has no visitor account system. Calculators run in your browser; entering a value does not submit a calculation form to our server.

Sharing a scenario places the selected inputs in the link fragment after #. That fragment is not sent in the HTTP page request, but anyone with the complete link can read the inputs. Older links can contain inputs after ?; those query parameters are sent with the page request and may appear in hosting logs. Use illustrative amounts when sharing private financial scenarios.

Watchlists and saved preferences use browser storage. They are not synchronized to an account and can be removed by clearing this site’s browser data. Other people using the same browser profile may see them.

Serving a page requires technical request data, including the requested address and network information, to pass through hosting and security infrastructure. This is separate from the calculator computation. We do not promise that browsing leaves no server records.

The site supports optional audience analytics. When configured, it records page views and interaction events such as opening a comparison or sharing a calculator. Our event properties exclude calculator amounts and search text. Hosting or security services may also measure requests; those counts do not identify human visitors or Google traffic by themselves.

Affiliate and official links open third-party services governed by their own privacy policies. Affiliate tracking can associate a visit or purchase with the referring link. Check the destination’s policy before providing account, payment or identity information.

Do not enter passwords, seed phrases, private keys, card numbers, tax identifiers or identity documents into calculators. This notice describes the public-site functionality, not the privacy policies of linked providers.
