Privacy

Nothing you do in this app leaves your device. That isn't a promise about how carefully data is handled somewhere else. There is no somewhere else — no account, no server, no analytics, no third-party scripts, no network requests of any kind once the page has loaded.

What is stored, and where

• The sweep log — timestamps, which steps you reached, which items you checked, and any notes you type. Written to your browser's local storage on your own device.
• Audio recordings, if you turn that feature on. Saved directly to your device's downloads folder. Never uploaded.
• Nothing else. No identifiers, no location, no device fingerprint, no usage statistics.

Camera and microphone

The app asks for camera access to control the flashlight and to show the front-camera view used for the infrared check. It asks for microphone access only if you start an audio recording. Neither stream is transmitted, recorded, or retained except for audio you explicitly start, which is written to your own downloads folder.

Sending your record

The hand-off buttons open your own mail, messaging, or share app with the record filled in. Sweep cannot send anything itself; you address it and press send. Once it leaves, it is governed by whichever mail or messaging provider you chose, not by this app.

Links out to other organisations

Step 09 links to a small number of victim-support services — StopNCII, NCMEC, the FTC's TAKE IT DOWN complaint portal, and the Cyber Civil Rights Initiative. Sweep sends them nothing. Opening one is an ordinary link you tap: no identifier, no referrer (this site sends none), and no indication that you arrived from here. Those organisations have their own privacy policies, and once you are on their site you are subject to theirs rather than this one.

The hashing tools linked there work the same way Sweep does: the fingerprint is computed on your device and only the fingerprint is sent. Your image never leaves your phone.

Deleting everything

Clear this site's data in your browser settings, or uninstall the app from your home screen. That removes the stored log completely. Files you saved to downloads and photos in your camera roll are yours to delete separately.

Limits of this tool

Sweep is a search procedure, not a detector. It cannot guarantee that a room is free of surveillance devices, and a completed sweep that finds nothing is not proof that nothing is there. It is not legal advice. If you believe you are being surveilled, contact law enforcement, and if the person you suspect is a current or former partner, contact a domestic violence advocate before removing or disabling anything.
