Neither the marketing site nor the demo webapp sets a tracking cookie. Plausible, our analytics provider, is cookieless by design: it records the page address, the site that referred you, and coarse browser and country information worked out from your request, without storing an identifier that follows you between visits or across to other websites. Because nothing is stored on your device and no profile is built, there is no cookie banner to dismiss.
Inside the demo webapp a recorded page address can include a synthetic account or case reference. Those refer to generated records, so they identify nobody.
The demo webapp does use a session cookie, strictly for keeping a synthetic visitor signed in to their synthetic account — it carries no personal data and is not used for advertising.
