Privacy

The short version

Calzentocollects no personal data. There are no user accounts. We don't ask for your email. We don't use third-party analytics, tracking pixels, ad networks, or fingerprinting. We don't sell anything. Your scenarios stay in your browser.

What we do receive

When you load a page, our web server logs the request URL, the time, your user agent, and your IP address — the same way every web server does. These logs exist to detect abuse and debug outages. They are not analyzed for behavior, not combined with anything else, not retained beyond 30 days, and never shared with third parties.

Calculator inputs (price, rate, down payment, etc.) live in your browser and in the URL query string. Sharing your URL shares your scenario; that is the only way it leaves your device. We never receive it.

Cookies

We set no cookies. None. See our cookies page for what that means and why.

Third-party assets

Fonts are self-hosted (Fraunces, IBM Plex Sans, IBM Plex Mono). No CDN ping, no Google Fonts beacon. No third-party JavaScript on any page.

Your rights (GDPR, CCPA, etc.)

Since we hold no personal data about you, there's nothing to access, correct, delete, or port. If you would like to verify this, contact us using the address on the contact page.

Changes

If we ever change this policy — for example, if we add opt-in analytics — the change will be announced on our changelog and the “Last updated” date above will move. We will never make a change that retroactively widens collection.
