The extension
On-device only mode
A switch that stops every network request to our API. You keep the writing-pattern analysis and same-origin provenance reads, and lose the rest.
Updated
What it does
On-device only is on when you install the extension, so network detection is something you opt in to rather than out of. While it is on the extension sends nothing to us: no text, no image URLs, no hostnames, no usage counts, no reports, no rechecks. Because our API is the only thing that forwards image files to provenance verifiers, nothing reaches OpenAI or Google either.
To opt in to network detection, turn On-device only off in the popup (or in the options page under Privacy and storage).
Your extension token stays in local storage, so opting in to network detection later does not mean connecting the extension again.
What still works
- The writing-pattern analysis, which always runs in the browser first.
- Content Credentials, EXIF, XMP and IPTC reads on images the page serves from the same origin, which the extension can decode itself.
- Hiding a post for the session, sensitivity presets and site rules, since those are all local.
What stops
- Watermark checks through provider endpoints (they run on our API).
- The community verdict cache, so nobody else's rechecks or reports reach you.
- The generator classifier and the model recheck (Pro), which are API calls.
- Community reports.
In practice most images on social platforms are served from a different origin than the page, so on-device only mode flags far fewer images. Text detection is less affected.
When to use it
Use it when you would rather not send the content of the posts you read to any server, even ours. The privacy policy describes exactly what leaves the browser in normal mode; see also What the extension sends.
