Cookies and Local Storage

Version / effective date: 2026-10-04

Essential storage

The app uses authentication cookies and local/session storage for login, security, remembered preferences and feature state. These are used to provide the service requested. Blocking essential storage can prevent login or preferences from working. Browser storage may include theme, units, navigation and device settings.

No optional tracking by default

The supplied DDC pages contain no advertising, session replay or cross-site analytics trackers. There is no optional tracking to enable through a bundled Terms checkbox. If optional trackers are introduced, they require a separate review and, where required, prior granular consent and an equally usable reject/withdraw choice. Third-party protections or integrations configured by an operator require their own assessment.

Payment and integrations

Stripe is loaded when you continue to its hosted checkout. Map, imagery, geocoding, streaming and other providers may receive requests when you use those features. They have their own notices. Use browser settings to clear local data; clearing a cookie does not cancel a subscription.
