Cookie Notice

Version 1.1.0-draft · Effective 2026-08-10 · Last updated 2026-08-10

This notice lists only technologies the product actually uses today. If we add anything else, this page changes first.

Strictly necessary

The authentication session and the cross-site request protection are required for the service to function. They cannot be switched off while you are using a signed-in account; signing out clears the session.

Preferences

The sidebar-state cookie and the two narration keys only record interface preferences. You can remove them by clearing cookies and site data for this site; the app still works without them.

Analytics

None. No product analytics, session-replay or heatmap tool is installed, and we do not set analytics cookies.

Marketing and advertising

None. There are no advertising pixels, conversion tags, retargeting scripts or third-party tracking cookies, and we do not share information for cross-context behavioural advertising.

Your controls

Because everything listed above is either strictly necessary or a single interface preference, there is no consent banner and no category toggle: we are not going to show you a switch that does nothing. You can always clear cookies and site data in your browser, or block them, though blocking the session storage will sign you out. If we ever add a non-essential technology, we will add a working consent control here and in Settings before it loads.
