Is Copyfish safe?
Copyfish routes images through a public CORS proxy and sends tab screenshots to a third-party OCR service via a hardcoded shared API key.
When extracting text from images on a page, the extension passes image URLs through cors-anywhere.herokuapp.com, a public proxy not affiliated with the vendor, which receives both the URL and image content. Screenshots of the active tab are then sent as PNG data to ocr.space API servers using a shared API key embedded in the extension's config file. Both transfers occur without user authentication scoped to the individual user.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 2 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Findings
Image URLs routed through public CORS proxy for OCR processing
When you ask Copyfish to read text from an image, the extension can route the image URL through the public cors-anywhere.herokuapp.com proxy.
That proxy can receive the image URL and image content before the extension processes it.
What actually happens
The user starts OCR on an image.
Copyfish routes the image through a public third-party CORS proxy before processing it.
Captured request
Fields in the request
- Image URLhttps://example.com/images/receipt.png (illustrative)
Reveals the location of the image selected for OCR and may identify the site or page context.
- Image contentImage bytes for the selected OCR target (illustrative)
Contains the image data being processed, which may include text or visual information from the page.
Observation
Observed during dynamic analysis: the image context menu flow passes the image source URL into the OCR path, and the fetch target is built by prepending the public CORS proxy host to that source URL.
What it can do
Permissions this extension asks for, as declared in version 7.0.17. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data
Destinations our analysis observed Copyfish contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
