Privacy Policy

The short version

The calculators on this site run entirely in your browser. What you type into them — loan amounts, income, health details, cycle dates, anything — is never sent to a server, stored, or seen by us. The only feature that transmits data anywhere is the contact form.

What we don't collect

• No accounts, sign-ups, or passwords.
• No cookies, analytics scripts, or advertising trackers.
• No local storage of calculator inputs — reload the page and everything resets, because nothing was saved in the first place.
• Calculator inputs and results (mortgage amounts, income, BMI, cycle dates, etc.) never leave your device.

The contact form

If you use the contact form, the name, email address, and message you submit are sent by email to the person who runs this site, using Resend as the email delivery provider. That information is used solely to respond to your message — it isn't added to a mailing list, sold, or shared with anyone else. Resend processes the message on our behalf as a service provider; see Resend's own privacy policy for how they handle data in transit.

Hosting logs

Like virtually any website, the server or hosting provider this site runs on may keep standard technical logs (IP address, browser user-agent, requested page, timestamp) for security and debugging purposes. These aren't linked to any calculator input, aren't used for tracking or advertising, and aren't shared with third parties beyond what the hosting provider itself requires to operate.

Changes

If this policy changes in a way that meaningfully affects how data is handled, the "Last updated" date above will change to reflect it.
