This page lists everything this website stores in your browser, and what would be stored if you accepted analytics and advertising.
Stored by this site
| Key | Type | Purpose | When it is written |
|---|---|---|---|
| healthlab_age_ok | local storage | Remembers that you confirmed you are 18 or older on the front page | When you press Yes on the age check |
| healthlab_consent | local storage | Remembers your answer to the cookie bar | When you press Accept or Decline |
| healthlab_requests | local storage | A copy of the tour requests you send, shown on the confirmation page | When you send the request form |
If your browser blocks local storage, for example in a private window, nothing breaks: the site simply asks both questions again on your next visit.
Consent Mode, before anything else
The first script on every page sets Google Consent Mode v2 to denied for ad_storage, ad_user_data, ad_personalization and analytics_storage. It runs before any other script, so the page starts in the refused state rather than being moved into it later. Only pressing Accept changes the four signals to granted.
What would appear after you accept
| Name | Set by | Purpose | Lifetime |
|---|---|---|---|
| _ga | Google Analytics 4 | Tells one visit from another | up to 2 years |
| _ga_<container> | Google Analytics 4 | Keeps the state of a session | up to 2 years |
| _gcl_au | Google Ads | Links a visit to an advertisement you clicked | 90 days |
