This page lists every cookie and similar technology this website uses. Analytics run unless you opt out; you can change your choice at any time.
01 — Your choice
On this site, Google Analytics and Microsoft Clarity load by default. Choose “Opt out” in the cookie banner to switch them off. Your choice is remembered for 6 months and shared between our European and US sites.
02 — Always on (needed for the site)
These store your choices, not who you are. They are never used for tracking.

ariston_region | Remembers whether you chose our European or US site | 1 year |
ariston_lang | Remembers your language (set when we first match it to your phone or browser language, or when you pick one) | 1 year |
as-theme | Light or dark mode, if you switched it (stored in your browser, not a cookie) | Until you clear it |
ariston_lead_dismissed | Remembers that you closed the price-list popup (stored in your browser) | 30 days |
03 — Analytics (only with your consent)
Google Analytics (loaded through Google Tag Manager) shows us which pages are visited and how people arrive. Microsoft Clarity records anonymised sessions and heatmaps, with form fields masked, so we can see where visitors get stuck.
| Name | Set by | Kept for |
|---|---|---|
_ga, _ga_* | Google Analytics | Up to 2 years (Google default) |
_gcl_* | Google Tag Manager | Up to 90 days |
_clck | Microsoft Clarity | 1 year |
_clsk | Microsoft Clarity | 1 day |
CLID, MUID, ANONCHK, SM, MR | Microsoft Clarity / Bing | Up to 1 year |
When you reject or opt out, we delete these cookies from your browser.
04 — Without cookies
We count visits with Plausible Analytics, which uses no cookies and stores nothing on your device, so it runs without asking. If the site hits a technical error, Sentry receives an error report without your IP address or cookies.
05 — Only when you click
The booking calendar on the contact page is provided by Cal.com. It loads only after you click “Pick a time”; Cal.com may then set its own cookies under its privacy policy.
