Your images are yours.

What Witness does with your images

When you upload an image or video, Witness sends it to a processing server for analysis. The server runs detection models, produces a verdict (real or synthetic) with a confidence score, and returns the result to you.

Your image is deleted immediately after processing. It is not stored on disk, not saved to a database, not cached, and not written to any persistent storage. Processing happens in ephemeral containers that are destroyed after each request.

No accounts

Witness does not require an account. There is no sign-up, no email collection, no password, and no profile. You use the service anonymously.

Device identifier

Witness generates a random identifier (a UUID) and stores it locally on your device — in your browser's localStorage for the web app, or in extension storage for the Chrome extension. This identifier is used solely for rate limiting (to prevent abuse of the free service). It contains no personal information and cannot be used to identify you.

You can delete this identifier at any time by clearing your browser data. A new one will be generated on your next visit.

What Witness does NOT do

• Does not store your images or videos
• Does not train models on your uploads
• Does not sell, share, or transfer your data to third parties
• Does not use cookies for tracking or advertising
• Does not collect your IP address, location, or browsing history
• Does not require or collect email addresses or personal information
• Does not embed third-party analytics, ads, or tracking scripts

Aggregate metrics

Witness may log aggregate, non-identifying metrics such as total scan counts, verdict distribution, and average processing times. These metrics are never tied to specific images, devices, or individuals. They are used only to monitor service health and improve detection accuracy.

Infrastructure

Image processing runs on Modal, a serverless GPU platform. Each request runs in an isolated, ephemeral container. No user data persists between requests. The web app is hosted on Vercel. Neither platform receives personal information from Witness because Witness does not collect any.

Children

Witness does not knowingly collect information from children under 13. Since the service collects no personal information from anyone, this is true by design.

Changes to this policy

If this policy changes, the updated version will be posted here with a new date. Since Witness does not collect email addresses, there is no way to notify users directly — check this page if you want to stay current.
