Privacy
No accounts, cookies, ads or cross-site tracking. The measurements you type are processed in your browser and never sent to us. Updated 25 September 2026.
Your measurements
The calculator, converter and sister-size finder run as code in your browser. The numbers you enter are not sent to our server or stored anywhere. If you press Calculate, the numbers are placed in the page address (for example ?u=32&b=37) so you can bookmark or share the result; that address stays in your browser history like any other.
Analytics
On braatlas.com we count visits with two cookieless tools. Cloudflare Web Analytics reports aggregate page views, referrers, countries, browsers and load speed; Cloudflare states it uses no cookies or local storage and does not fingerprint visitors. Umami, which we host ourselves, records page views and a few button events (for example "calculate" and the size shown, with no measurements) without cookies. Neither tool lets us identify you.
Hosting
The site is served by Cloudflare, which processes your IP address and request details to deliver pages and block abuse, under its own privacy policy. We keep no request logs of our own beyond short-lived error logs.
Cookies and storage
The site sets no cookies and stores nothing in your browser's local storage.
If you email hello@braatlas.com, your message and address are kept in that inbox so we can reply. We do not add you to any list.
Advertising and affiliates
No ads. Size pages carry Amazon Associates search links, added 26 September 2026: as an Amazon Associate, Bra Atlas earns from qualifying purchases. Clicking one sends you to an amazon.com search for that size, tagged so Amazon can credit us if you buy; it does not change the size we show, and Amazon's own privacy notice covers what happens on their site. If another affiliate programme is joined, this page will be updated first and the change dated.
Sources
