PRIVACY / BROWSER STORAGE
Layer400 uses a small amount of browser storage to keep accounts secure and remember choices on the device. This page explains those uses without hiding them behind a generic banner.
A cookie is a small value a website asks a browser to retain and return with later requests. Local and session storage keep values inside the browser. Similar technologies can remember a session, protect a form or retain a setting such as map theme or measurement units.
Essential session, sign-in, sign-out, verification and anti-forgery values are used by Layer400 and its identity service. Without them, account features cannot work securely. They normally expire at sign-out, after inactivity or at the security limit set for the session.
The browser may retain choices such as light or dark display, measurement units, dismissed guidance and the last non-sensitive map view. These values make repeat visits more useful and can be cleared through browser settings.
Short-lived values may help enforce rate limits, identify a valid request, distribute traffic and defend the service. They are used for operation and security rather than advertising.
If optional analytics are introduced, they will be configured to collect only what is reasonably needed and will not be activated without consent where consent is required. The preference itself may need to be remembered.
Layer400 does not currently use third-party advertising cookies or sell browsing profiles. A map provider can receive ordinary web requests needed to deliver map tiles; that is described in the Privacy notice and does not permit Layer400 to promise how the provider handles unrelated visits.
You can block or clear cookies and site storage through the browser. Blocking essential storage can prevent sign-in, account security, contributor enrolment and saved preferences from working. You can still access public information that does not require those functions.
If a consent control is shown, changing it affects optional technology from that point onward. It cannot undo aggregate reporting already created lawfully.
We will update this page if a new category of browser storage is introduced. Questions can be sent to [email protected].
