Cookies are small text files that websites store on your browser to remember information about you between visits — things like whether you are logged in or your language preference.
The Alventis browser extension does not use cookies for authentication. Instead we use browser local storage — chrome.storage.local in Chrome, Edge, and Brave, and browser.storage.local in Firefox. This is more privacy-respecting than cookies because it is not automatically sent with every web request.
We store exactly one item in browser local storage: your JWT authentication token. This token expires after 24 hours and is renewed on each login. It exists only on your device and is only sent to api.alventis.ai when you make an authenticated request. It is never sent to any other server.
The alventis.ai website uses a minimal session cookie to maintain your login state when you access the web dashboard. This cookie is:
