This notice explains the cookies and browser storage used by the ONDSU website and its connection to the Acoustic Score quiz. You can accept, reject or change optional storage using “Cookie settings” in the website footer.

Necessary browser storage

ondsu_consent

Local storage on the website you visit. It records your cookie categories, the date of your choice and the policy version. It has no automatic expiry. It remains until you clear browser storage; a new policy version may ask you to choose again. This storage is used to remember your choice and is treated as strictly necessary under § 25 (2) TDDDG.

Analytics cookies and browser storage

These cookies and identifiers are used only on ondsu.com and www.ondsu.com after you accept analytics. Analytics are disabled on Fimo review and local development hosts.

_ga and _ga_<container> (Google Analytics)

Distinguish visitors and maintain Google Analytics session information. Stored for up to two years, with expiry renewed through use. Your browser settings may shorten this period. The quiz at quiz.ondsu.com does not load Google Analytics itself.

fimo.analytics.visitor-id and fimo.analytics.session-id (Fimo)

Fimo uses a visitor identifier in local storage and a session identifier in session storage to count visits and page views. The visitor identifier has no automatic expiry and remains until browser storage is cleared. The session identifier lasts for the browser tab’s session. Both are created only after analytics consent and are removed when you withdraw it.

ondsu_vid (ONDSU)

A visitor identifier used to connect website page views with an Acoustic Score submission. Stored for up to 365 days. With analytics consent, it is available across the ondsu.com domain and can be passed to quiz.ondsu.com in a link or the embedded quiz URL.

Marketing and booking services

LinkedIn Insight Tag

Provider: LinkedIn Ireland Unlimited Company. Purpose: audience insights, advertising measurement and building retargeting audiences. The tag loads only after Marketing consent on ondsu.com and www.ondsu.com. It remains off on preview/local sites, the staff visitor tool and the separate quiz. LinkedIn may collect visits and Website Actions even when no LinkedIn ads are running.

LinkedIn lists the following advertising and measurement cookies: UserMatchHistory, AnalyticsSyncHistory, lms_ads and lms_analytics (30 days); li_sugr (90 days); li_fat_id on the first-party domain (30 days); and li_giant on the first-party domain (7 days). Its services may also use cookies such as bcookie (one year), lidc (24 hours) and li_gc (six months). Which cookies are used depends on your browser, region, LinkedIn settings and the enabled features. These are provider-published lifetimes, not a claim that every cookie is set on every visit.

LinkedIn also documents a first-party LinkedIn Ads ID (li_adsid) for visitors outside the EU, EEA, Quebec and UK. Its current cookie table does not list a lifetime for that identifier. Browser storage can persist until its expiry, withdrawal cleanup or deletion through browser settings.

LinkedIn Cookie Table

You can withdraw Marketing consent using Cookie settings. We stop the tag, reload the page to remove its listeners and remove accessible first-party identifiers used by the integration. We cannot delete cookies on LinkedIn’s own domains. You can manage those through LinkedIn or your browser settings. Withdrawal does not erase data LinkedIn has already received.

Booking services

LinkedIn and Meta marketing tracking load only after you accept Marketing. Cookie permission is separate from permission to send marketing emails.

When you choose “Book a call”, Calendly loads its booking service. Its Privacy Notice explains the cookies used by that service and how to change your preferences.

Meta Pixel (Facebook / Instagram)

Provider: Meta Platforms Ireland Limited. After Marketing consent, the pixel records page and product views, clicks to open the brochure, Acoustic Score and booking service, and confirmed successful enquiries for advertising measurement and Facebook/Instagram advertising audiences. It stays off on preview and local development sites, the staff visitor tool, newsletter and order utilities, the questionnaire handoff and the separate quiz.

_fbp distinguishes browsers. _fbc stores a Meta advertising click identifier when the visited URL contains fbclid. Their usual lifetime is up to 90 days and may be renewed through use; browser settings may shorten it. Which identifiers are set depends on the visit and browser.

When you withdraw Marketing, we stop the pixel, remove accessible _fbp and _fbc cookies on our domain and reload the page to remove vendor listeners. We cannot delete cookies on Meta domains. Withdrawal does not erase data already held by Meta.

Meta Cookie Policy

Changing your choice

Open “Cookie settings” in the website footer to change or withdraw your choice. Withdrawing analytics consent stops further website analytics and removes Fimo’s stored analytics identifiers, the ONDSU visitor identifier and Google Analytics cookies set on the website. You can also clear cookies and local storage through your browser settings. Withdrawal does not affect the lawfulness of earlier processing.
