Cookie notice

Last updated 11 October 2026

This notice describes the cookie and browser storage Hawkeye actually uses. BrownHawke Engineering in the United Kingdom operates Hawkeye. Questions: enquire@brownhawke.engineering.

Hawkeye does not use analytics cookies, advertising cookies, or third-party cookies. The sign-in cookie and the storage below are used only to provide the service you asked for: to keep you signed in, to remember the appearance you chose, and to keep the chat workspace open. Because none of it is used for anything else, Hawkeye does not show a consent banner. A footer line links here instead.

Sign-in cookie

hawkeye_session: Keeps you signed in. First-party, HttpOnly, SameSite=Lax, and host-only. It is marked Secure when the page is served over HTTPS. The default lifetime is 30 days (720 hours). Signing out clears it immediately. It holds a session token, not your password.

localStorage

These keys stay in this browser until you clear site data. Signing out removes every key except the appearance setting.

hawkeye-theme: The appearance you chose: light, dark, or match this device. Left in place when you sign out so the next page still matches.
hawkeye-agent-threads: A local cache of your Hawkeye agent chats so the list can paint before the account reloads. The account copy kept by Hawkeye is the record that is kept.
hawkeye-active-agent: Which Hawkeye agent you had open.
hawkeye-speak-replies: Whether spoken replies are on.
hawkeye-pending-signin: The Hawkeye agent you were connecting, so that sign-in can finish.
In-app notices: Which in-app notices and preferences were already shown, so they are not repeated.

sessionStorage

These keys last for the browser tab. They are cleared when the tab closes, and when you sign out.

hawkeye-thread-seen: Which chats were already seen in this visit, so old replies are not marked as new again.
hawkeye-prefer-bot: Which Hawkeye agent this tab should open.
hawkeye-pane: Which workspace pane was open: chats, projects, or account.
hawkeye-login-note: A one-time note after a password reset, shown on the next sign-in page and then removed.

How to clear them

Sign out to drop the session cookie and the workspace keys. Use your browser's site settings to clear cookies and site data for this host, which also removes the appearance setting. Blocking cookies will sign you out, because Hawkeye cannot keep a session without hawkeye_session.
