Privacy policy of the browser extension Aethern - API tester.

This policy covers the browser extension only. Last updated on 10 November 2026.

What the extension does

The extension sends the HTTP requests you compose in the API tester of AETHERN to the host you addressed, and returns the answer to the tester in the same browser. It exists because a web page cannot reach an API on your own computer or your local network.

What it processes

The request (address, method, headers and body) and the answer, for as long as the request takes. They pass through the extension in your browser. The extension does not store them.

What it stores

On your device only: that you allowed the AETHERN portal to use the extension, and the language you chose. The hosts you allowed are kept by your browser as permissions of the extension.

What it shares

Nothing. The extension sends no data to AETHERN or to any third party. A request goes only to the host you addressed, and no cookies are sent with it. There is no analytics and no tracking. The extension does not read or change the pages you visit.

Your control

In the extension's settings you can remove a host you allowed, or stop the portal from using the extension. Removing the extension removes everything it stored.

The API tester itself

What the API tester in the portal keeps for your account, such as saved requests and the history of what you sent, is part of the AETHERN platform and not of this extension.
