Privacy Policy

Effective October 1, 2026.

The short version: our calculators run entirely in your browser. We don't collect, store, or see anything you type into them, and we don't ask you to create an account.

Information we collect

We don't collect personal information through the calculators. If you email us, we receive your email address and message so we can reply — we don't sell it, share it, or use it for marketing.

Cookies

We don't set cookies ourselves. If you contact us through a form hosted on this site in the future, that may change, and this policy will be updated.

Advertising

We plan to show ads to keep the tools free. When advertising is enabled, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the internet. You can opt out of personalized advertising by visiting Google Ads Settings. This is required disclosure under the Google AdSense program policies.

Analytics and hosting

We don't currently run analytics. Our hosting provider may process standard server logs (such as IP addresses) to keep the site running securely.

Changes to this policy

If this policy changes, we'll update the date below and post the new version here.
