Cookie Policy
Last updated: 24 June 2026
BuildMetricLab does not set any tracking, advertising, or analytics cookies, on the US site or any other locale.
Local storage only
The Site uses browser localStorage for a single purpose:
bml-theme— stores your chosen theme (lightordark). If the key is absent, your operating-system preference is used.
Calculator inputs are not stored — refreshing the page resets them. The value we write is the string "light" or "dark"; nothing else. This value stays on your device. We never receive it.
Consent management — InMobi Choice
We use InMobi Choice, a certified consent management platform, to present your privacy choices and record them. Under the California Consumer Privacy Act and the Virginia, Colorado, Connecticut, Utah, Texas, Oregon, and Montana state privacy laws, this is an opt-out message rather than an opt-in banner. InMobi Choice records your choices in the following cookies, kept for up to 13 months:
IABGPP_HDR_GppString— your choices as an IAB Global Privacy Platform string, used for US state privacy signals.usprivacy— your opt-out choice under US state privacy laws.euconsent-v2— used where the IAB Transparency & Consent Framework applies.
These are strictly necessary to remember your choice. We honor the Global Privacy Control (GPC) browser signal as a valid opt-out.
Clearing data
You can clear the bml-theme entry at any time via your browser's site-data settings, which resets the theme to your OS preference on the next page load. To change your privacy choices, use the Cookie preferences link in the footer, which reopens the InMobi Choice message.
