Cookie and measurement notice
Optional measurement is off until you choose it. This notice lists the browser storage the Toolkit currently supports. Updated 3 September 2026.
Your choices
The Toolkit groups optional technologies into Analytics, Advertising measurement, and Experience replay. Necessary storage supports requested features and cannot be disabled through the preference panel. Rejecting optional measurement does not block worksheets, printing, accounts, saves, or reminders.
Open Privacy choices in the site footer whenever you want to change or withdraw a choice. A Global Privacy Control browser signal keeps advertising measurement disabled.

What is not active
Google Ads conversion cookies, Meta Pixel, Meta Conversions API, advertising matching, remarketing, and session replay are not currently active. Their administrative controls fail closed, and no provider script exists for Meta or replay in the current release. The experience-replay preference is unavailable until a reviewed provider and disclosure exist.
Private worksheet content
Worksheet answers, generated guidance, saved titles, reminder text, names, email addresses, account identifiers and record identifiers are not included in optional measurement. Optional provider tracking is also suppressed when a worksheet is opened through a private saved-record URL. See the privacy policyfor provider, retention, hosting and rights information.
