Privacy policy
Short version: tdeecalculator.page does not collect, store, or share personal data. Every calculation runs locally in your browser.
What we collect
Nothing. The calculator runs entirely in client-side JavaScript. Your age, height, weight, body fat, and activity level never leave your device and are never sent to a server.
Cookies and tracking
This site sets no cookies and loads no analytics or advertising scripts. There are no third-party trackers, no fingerprinting, and no session recording of any kind.
Shared links
If you use “Copy link”, your inputs are encoded into the URL so the page restores your last result. That link only contains what you deliberately copied and shared.
If you email us for support, we receive your address and message and use them only to reply. We do not build mailing lists and do not share addresses.
Hosting
Like any web server, our host may process generic technical request metadata (IP address, timestamps) for delivery and abuse prevention under its own retention rules. We do not access or store it on this site's behalf.
Changes
If we ever change collecting behavior, this policy will be updated and the change noted with a date above. Last reviewed: November 2026.
