Privacy policy

Short version: this site has no accounts, no sign-ups, and stores nothing you type. Calculator inputs are processed in your browser and never sent to our servers.

What we collect

• Hosting logs. Our host (Vercel Inc.) processes standard request data — IP address, user agent, pages requested — to serve and secure the site.
• Aggregate analytics. We use Vercel Analytics, a cookie-free analytics service that records anonymized page views and visit metadata. It does not track you across sites or build profiles.

We set no advertising cookies and run no third-party trackers.

Affiliate links

Some broker links are affiliate links (see Disclosures). If you click one, the destination site may set its own cookies under its own privacy policy — that happens on their domain, not ours.

If advertising is added

Should we add display advertising (e.g. Google AdSense) in the future, ad providers may use cookies or similar technologies, and this policy will be updated first, including any consent mechanisms required where you live.

Your choices & contact

There's no account to delete and no marketing list to unsubscribe from. Questions about this policy: contact us.
