Cookies and similar storage
Cookies are small pieces of data stored by your browser and potentially sent with matching requests. localStorage keeps data in your browser without automatically sending it with every request. Tags, pixels and iframes may also contact external services.
Necessary storage
nu-isoleren.consent is this site’s localStorage item. It stores necessary, analytics and marketing choices, the consent version and saved/expiry timestamps. A choice is valid for at most 180 days. Afterwards it is no longer applied and the banner appears again; localStorage does not automatically physically delete the old value. Necessary storage remains active. NEXT_LOCALE is the next-intl language cookie, saved when needed. The current configuration sets no max-age: it is a session cookie, whose restoration also depends on browser settings. No other application-owned sessionStorage use was identified.
Analytics
The analytics category is disabled by default. We use Google Analytics 4 for website and visitor statistics and Microsoft Clarity for usage analysis, heatmaps and session replays. Analytics cookies are only permitted when you consent to them. When analytics_storage is set to denied, supported services may send limited cookieless measurement requests without using analytics cookies. Analytics consent is separate from marketing consent.
Google Analytics 4
Google Analytics 4 is used to measure information such as page views, website usage and technical information about visits so that we can improve the website and our services. When you accept analytics cookies, Google Analytics may set first-party cookies such as _ga and _ga_* for pseudonymous measurement and to associate visits and sessions. Without analytics consent, analytics_storage remains set to denied and analytics cookies are not permitted. If you previously gave consent and later withdraw it, the website removes accessible first-party _ga and _ga_* cookies. This does not automatically erase information already processed or stored by external providers.
Microsoft Clarity
Microsoft Clarity is used for behavioural analytics, heatmaps and session replays. Without analytics consent, the Clarity tag may send limited cookieless measurement data. When you accept analytics cookies, Clarity may use cookies to link page views and sessions together. The main first-party cookies are _clck, which stores a pseudonymous Clarity user ID and preferences for this website, and _clsk, which links multiple page views into a single Clarity session. Depending on your consent choices and Microsoft settings, Microsoft cookies such as CLID, MUID, ANONCHK, MR and SM may also be used. Analytics storage is only permitted when analytics_storage is set to granted; advertising-related storage remains subject to the separate marketing consent.
Marketing: Google Ads and Meta Pixel
Google Ads and Meta Pixel are managed through GTM, not separate website scripts. Marketing is off by default. With consent these services can measure campaigns and conversions, including visits to contact or quote thank-you pages. Exact tags, cookies, recipients, individual purposes and lifetimes still need checking in the external container and production browser. We do not publish an unverified cookie list.
Google Tag Manager and Consent Mode v2
GTM-P6K3L9WQ loads after the website first sets analytics_storage, ad_storage, ad_user_data and ad_personalization to denied and processes any valid stored choice. Analytics controls analytics_storage; marketing controls the three advertising values. The same analytics consent state is also used by the directly integrated Google Analytics 4 tag. Changes are immediately passed through Consent Mode and nu_consent_update. GTM itself may load while consent is denied. Depending on their settings, Google tags may then send limited cookieless measurement requests. Meta tags require their own restrictions in GTM; Consent Mode does not automatically restrict every tag. Without JavaScript, the noscript iframe may contact Google but cannot read localStorage preferences. This fallback must not run optional marketing or analytics tags; its container settings need to be checked.
Google Maps and reviews
The contact-page Maps iframe currently loads directly when the browser loads it, independently of cookie preferences. Google may receive technical data and use its own storage. Exact cookies and durations have not been established. Google Places supplies reviews through our server; external reviewer photos may also make requests to Google. These services are not described as already consent-gated.
Accepting, rejecting and changing preferences
On your first visit you can reject all, set preferences or accept all. Analytics and marketing can be selected independently. “Cookie preferences” in the footer or below lets you change or withdraw your choice later. Missing, invalid, expired or outdated-version preferences cause the banner to appear again. When you withdraw analytics consent, analytics_storage is immediately set to denied and the website removes accessible first-party Google Analytics cookies _ga and _ga_*. This does not automatically erase information that external providers processed or stored before consent was withdrawn. Clearing browser storage also removes your saved cookie preference.
External storage still to verify
The GTM container contents and providers’ production settings are outside this website code. Specific names, domains, lifetimes and transfers will be added only after reliable verification. See the privacy policy for contact details, data processing and your rights.
