Public Website Analytics

Website analytics notice: October 6, 2026

On the public marketing pages of sentinan.com, we use Google Analytics 4 to understand which content is viewed and how visitors use our demonstrations. This website notice is separate from the clinical application policy below.

Google Analytics runs in cookieless measurement mode: analytics storage, advertising storage, advertising data use and advertising personalisation remain denied. We do not set analytics cookies or create persistent visitor IDs. We do not use Google Signals or advertising personalisation.

We send page views, section and news views, scroll-depth milestones, navigation and report-link clicks, demonstration interactions, audio and video playback milestones, transcript openings, and whether an enquiry succeeded or failed. Google also receives technical request information, such as IP address, browser information, language and timestamps. Cookieless measurement is not the same as sending no data to Google.

Our events exclude names, email addresses, enquiry contents, patient information and recordings. Page query strings and URL fragments are removed; recognised referral sources are reduced to their public website domain. We do not run this integration on the clinical dashboard, screening page, sample report, local previews or deployment previews.

We use these measurements to improve the website. Google processes the measurements to provide Analytics, which can involve processing outside your country. Read Google's Privacy Policy for information about Google's handling of data.

We respect Global Privacy Control and Do Not Track browser signals. You can also disable website analytics below. Only this preference is saved in your browser's local storage; it is not a tracking identifier.
