the design, so you don't need the promise
A metering page necessarily points a camera at whatever you're photographing — sometimes homes, sometimes people. The handling here is built so nothing sensitive can accumulate: every frame is collapsed into a single brightness statistic inside this tab and then released. No frame is drawn to storage, encoded, or held beyond the instant of measurement. The preview you watch is your device's own local stream, the same one your camera app shows.
Structurally offline: the site is a set of flat files served from a CDN edge. No server-side program exists behind it, which means no upload endpoint, no image processing queue, no place your viewfinder could arrive at. Meter in airplane mode to check — everything keeps reading.
Kept on your device only: your lens aperture choice, trim, and reference match, in localStorage where they belong. Clearing site data resets the meter to factory.
Watching the watchers: this page runs no analytics, no advertising tags, and writes no cookies. Two typefaces come from Google Fonts on first load and cache thereafter. The CDN's own bare request count is the only trace a visit leaves. What you photograph — and how much light it sat in — was never this site's to know.
