Privacy Policy
The calculator does its math inside your browser. Your weight, sex setting, drinks and hours are never sent to a server, and the site keeps no copy of them. If you use "Copy link to this result", your inputs are written after the # in that link. Browsers do not send that part of an address to a server, so they reach only whoever you share the link with.
Cookies, analytics and ads
The site's own code sets no cookies, on the calculator or on any other page. BAC Calculator has no analytics, no ads and no third-party scripts. If analytics or ads are ever added, this page will change on the same day to name the provider, what it collects and how to opt out.
Hosting logs
The site is served by Cloudflare. Like any web host, Cloudflare processes request data such as your IP address, browser type and the page asked for, to deliver pages and protect the site from abuse. If Cloudflare's bot protection is switched on, Cloudflare can also set its own security cookie to tell people from bots. That data is handled under Cloudflare's own privacy policy.
If you email admin@baccalculatr.com, your address and message are used only to reply to you and are not shared.
Children
The site is not directed at children under 13 and does not knowingly collect their information.
Changes and contact
Any change to this policy is posted on this page with a new Last updated date. Questions about privacy go to the same email address.
