Cookie policy
Last updated 31 August 2026
Cookies and similar storage help the site remember choices. CHART uses a small number of first-party keys in localStorage — functionally equivalent to cookies for this policy.
Strictly necessary
chart-grok-prefs stores your cookie decision and any saved graphics. These are required for the reading list and to stop the consent bar returning every visit. They are first-party, not sold, and have no advertising profile.
Analytics (optional)
If you choose “Accept all”, we record a preference to allow anonymous usage measurement. This build does not load a third-party analytics tag; the flag is stored so a future, disclosed measurement tool can honour it. Default is off.
Your current choice
Status: not yet chosen. Analytics preference: off.
