Birthday and date inputs are processed in the browser, without being put in URLs or uploaded to a database. Checklists are stored in this browser only when you enable device storage; switching it off removes the saved copy. They do not sync across devices. Public pages require network requests; hosting may process IP addresses and technical logs. Administrator sign-in uses an essential cookie and a database account. When Google Analytics is enabled, public pages load it automatically without an accept or decline prompt. Google may use cookies to process page visits and browser and device information. We use it for traffic statistics only, with ad personalization disabled; tool inputs, URL query parameters and administrator pages are not sent.
By default this list stays in the current page. Enable device storage to resume in this browser; switching it off deletes the saved copy. No cross-device sync. Printing includes every item and status.
