What these technologies do
Cookies are small browser files. Local storage is a different browser-storage mechanism; similar privacy rules apply to its use. This website uses necessary storage to remember privacy choices and optional services for audience measurement and external videos.
Choose before activation
Google Analytics is blocked until you authorise analytics. YouTube is blocked until you authorise external videos. Accepting one category does not activate the other. “Reject optional services” leaves both off. Merely browsing, scrolling or closing the settings is not consent. Local fonts, images, native galleries and locally hosted videos do not require those optional services.

| PREF (if set by YouTube) | Google / YouTube | External video · optional | Playback preferences | 8 months after use, according to Google |
| __Secure-YNID / legacy VISITOR_INFO1_LIVE | Google / YouTube | External video · optional | Service preferences, diagnostics and measurement; if used by the player | 6 months, according to Google |

The consent entry includes an expiry timestamp: local storage does not expire by itself, so the website discards it when it is next read after 180 days. Google Analytics is configured with a 180-day cookie limit and no rolling renewal. Optional services are not installed when rejected.
Storage inside YouTube
The YouTube row describes browser-storage families that the privacy-enhanced player may use; it is not a claim that every entry is installed in every browser. Google can also use cookies for playback, security and preferences depending on the environment. Names and durations can change independently of this website. Before activation, consult Google’s storage and cookie information. Authorisation is required before connecting the player, even when a browser blocks third-party cookies. Clearing storage held by YouTube must be done through that provider or browser settings, as this website cannot delete another domain’s data.
Change or withdraw your choice
The footer’s “Cookie preferences” control reopens the settings on every page. Turning analytics off prevents subsequent activation, removes this domain’s Analytics cookies and reloads an already measured page to stop the loaded integration. Turning YouTube off removes any active external players. Necessary consent storage remains to remember your rejection.
Browser controls and JavaScript
You can also inspect or clear storage in your browser: Chrome · Firefox · Safari · Edge. Blocking storage may mean your choice cannot be remembered between visits. Without JavaScript the optional integrations do not load; the ordinary external links remain available.
