Privacy Policy

Effective September 28, 2026

What we collect

The calculators run in your browser. Numbers you type are not sent to us unless you submit a form.

How we use it

We do not sell or rent your personal information.

Service providers

Form submissions are stored with Cloudflare, which hosts this site. We may use an email service provider to send newsletters, and Gumroad processes SnowX Approved Funds payments; payment card details go directly to Gumroad and its processors, not to us. Each provider handles data under its own privacy policy.

Your choices

Every email includes an unsubscribe link. You can ask us to access, correct or delete your information by email at [email protected].

Retention and security

We keep your information while you remain subscribed or on a list, and for a reasonable period afterward for record keeping. We use reasonable safeguards, but no system is perfectly secure.

Children

This site is not directed to anyone under 18, and we do not knowingly collect their information.

Changes

If we change this policy, we will update the effective date above.
