What cookies are
Cookies are small pieces of data that a website or third-party service can store through a browser. Related technologies may include local storage, pixels, web beacons and identifiers used in network requests.
Site operation
The core static pages do not require an account cookie. The local planning tools work in the current page and are not intended to save a project to the site’s server.
Advertising cookies
Google AdSense and advertising partners may use cookies or similar technologies for ad delivery, frequency limits, fraud prevention, measurement and personalization where permitted.
Consent choices
A regional consent message may let you accept, reject or manage particular advertising purposes. Changing a browser or device, clearing storage or using private browsing can affect saved choices.
Browser controls
Most browsers let you delete or block cookies. Blocking third-party scripts may prevent ads from appearing. Browser controls do not necessarily remove information already processed under another service’s policy.
