Privacy

The extension scores posts you already see on the LinkedIn feed. Code: github.com/pawelmamcarz/linkedin-ai-slop.

What leaves the browser

When a post comes into view, the extension sends the post id, the text (up to 6000 characters), and optionally the name visible on the card. Own text shorter than 200 characters (after hashtags, mentions, links, and emoji are removed) is not sent. Comments under the post, and the nested reshare text, are skipped for the outer card.

The default address is https://proxy-production-ebcc.up.railway.app. You can set your own proxy in the options, including a local one.

Where it goes

The proxy calls TypeSafe Jev (POST https://api.typesafe.ai/v1/systemone, model jev-latest). TYPESAFE_API_KEY lives only on the server. It is not in the extension and not on this page.

The proxy does not write post text to disk. Memory holds a per-IP request counter (60 second window, 60 scores per minute) and a SHA-256 of the normalized text together with the verdict, with a time to live (12 hours by default). The raw text is not kept in that cache. A cache hit does not call TypeSafe again.

What stays in the browser

Extension storage (storage.sync, or storage.local when sync is unavailable) stores the toggle, the threshold, the mode (Demo, BYOK, or Pro), the proxy URL, and an optional Pro token. The Pro token is not TYPESAFE_API_KEY. That covers Chrome, Brave, Edge, Firefox, and Safari. The extension does not read your LinkedIn profile beyond the visible post card and does not sell data.
