Point a camera at yourself, wearing the pattern, and watch a real
surveillance model try to find you. No lab, no middleman,
no trust required. The detector runs on your own device, and
you read the result with your own eyes.
Private by constructionnot by promise
Runs on your device
The detection model is downloaded once and runs inside this
browser. Your camera feed is never uploaded, never proxied, never
stored.
Nothing is tracked
No analytics, no advertising, no cross-site cookies. Your camera
and your results stay on your device: we only see how a test went
if you choose to send us that session.
Yours to erase
Recordings and your face data live in this browser only, and one
tap deletes them for good. Sign out and the models stay cached for
next time.
The one exception, and only if you choose it: a
session records to your own device as you test, so you can review it
or, if you want to, send it in. Nothing is transmitted on its own. On
the stop screen you pick one of three: send nothing, send the data
only (detections, confidences, heatmaps), or send the data and the
video. You see exactly what would go before anything leaves your
device, and you can have it deleted later.
What this tool actually does
A modern camera does not "see" a person. It runs the picture through a
detection model that outputs a confidence score: how sure it is that a
person, a face, or a specific identity is present. This tester runs
those same models, in your browser, so you can watch the score for
yourself with and without the pattern.
The honest bar is simple. A pattern only counts if the model can find
you in plain clothing and then cannot find you wearing the print, at
the same distance and the same light. The tool enforces that: it
refuses to compare two takes that do not match, because distance and
brightness move the score on their own.
Exactly what we have, and what we don't
No vague promises. Here is the complete list of what reaches our
server, and why each thing is there.
Your email address. You sign in with it, so of course
we have it. It is used to send your sign-in link, to enforce your
account's fair-use limit, and to reply to you if you send us a
diagnostic. It is never sold, never shared, and never used to track you
anywhere else.
A tally of which models your account has downloaded.
The detection models are licensed, so we keep the model name and the
date. That is all it is for: keeping the free limit fair and shutting
off abuse. It records nothing about your results.
Only the sessions you choose to send us.
Your session records to your own device automatically, and stays
there. When you decide to send one, you choose whether it is the data
only (detections, confidences, heatmaps, and the session details) or
the data and the short video, and it is tied to your account on
purpose: we need it to see the problem and to write back to you, and it
is what credits your contribution. You preview exactly what will be
sent, nothing leaves your device until you approve it, and you can have
it deleted afterward.
What never reaches us at all: your live
camera while you test (it is processed in your browser and discarded
frame by frame), your results unless you choose to send a session,
and your face (if you enroll one for the recognition test it
stays in this browser as a list of numbers, never uploaded, never part
of a diagnostic). No analytics, no advertising, no cookie that follows
you around the web.
