What browser cookies and local storage are
Cookies are small data files that a website or third-party service may ask a browser to store. Similar local technologies can include browser storage, identifiers and web beacons. The ProfEng AI engineering workspace itself uses browser state to operate interactively and does not require a user account or server-side project archive.
Google AdSense advertising cookies
Google AdSense may use advertising cookies to improve ad relevance, measure campaign performance, prevent invalid activity, manage frequency and avoid repeatedly showing the same advertisement. Depending on browser, region, consent choices and Google settings, third-party advertising cookies may be associated with doubleclick.net or Google domains. Historical references to a DoubleClick “DART cookie” describe an older advertising-cookie terminology; current Google controls and disclosures should be used for present-day preferences.
Google Analytics
Google Analytics is used to understand aggregate usage of profeng.net, such as visits, pages and interaction patterns. Analytics technologies may use cookies or related identifiers depending on consent status and configuration.
Consent for EEA, UK and Switzerland visitors
Where required, advertising and related storage choices are presented through a consent-management mechanism. The availability and behavior of personalized advertising depends on the visitor's region, choices and the consent signals passed to Google. Visitors may revisit their choices using the Privacy & Cookie Settings control below.
Manage advertising preferences
Visitors can review Google ad personalization preferences at Google Ads Settings and can learn more about Google's advertising technologies at Google advertising technologies. Browser settings may also allow cookies to be blocked, deleted or restricted. Blocking storage can affect advertising, measurement or other site behavior.
