What the extension does

Section titled “What the extension does”

When you clip a page or open the related-items panel, the extension sends the page content (or your selection) to a Nimbus Gateway running on your own machine at 127.0.0.1 (loopback). That is the only network destination the extension ever contacts — it declares host access to http://127.0.0.1 and http://localhost only, and cannot reach any remote server.

What is stored, and where

Section titled “What is stored, and where”
  • Pairing token and gateway origin. After you pair with your local gateway, the extension stores a bearer token and the gateway’s loopback origin in the browser’s local extension storage (chrome.storage.local) on your device. The token is used only as the Authorization header on requests to your local gateway. It is never logged, never placed in a web page, and never sent anywhere else. Revoke it at any time on the gateway with nimbus clip revoke.
  • Offline clip queue. Clips made while the gateway is unreachable are stored locally and retried automatically. The bearer token is not stored in the queue.

All of this data stays on your device. Uninstalling the extension removes it.

No third parties, no tracking

Section titled “No third parties, no tracking”

The extension makes no cloud calls, includes no third-party analytics or advertising code, and does not track you across sites.
