What Are Cookies
Cookies are small text files stored on your device when you visit a website. They help the website function, remember your preferences and improve your experience.
How We Use Cookies
We keep our use of cookies to a minimum. The website uses essential cookies to operate and cookieless analytics to understand traffic anonymously. Under the opt-out model, it also uses Google Analytics statistics cookies and Meta Pixel advertising cookies from your very first visit. You can turn both off at any time by clicking “Reject” on the cookie notice.
Essential Cookies
The website always sets the essential cookies needed to operate; the statistics and advertising cookies described below are also set from your first visit, unless you have chosen “Reject”. Once you make a choice on the cookie notice, the website stores a single cookie named siri9_consent (kept for 1 year) to remember your choice so you are not asked again; the same choice is also stored in your browser local storage under the key siri9:cookie-consent:v2. It cannot be turned off separately through the site, because removing it simply brings the cookie notice back.
Cookieless Analytics
We use Cloudflare Web Analytics to measure traffic. This tool does not use cookies and does not collect personally identifiable information, helping to protect your privacy.
Statistics Cookies (Google Analytics)
Google Analytics 4 is Google’s visit measurement tool. Its script (gtag.js) is loaded from googletagmanager.com and sets the _ga and _ga_FF8JP2EF4X cookies in your browser. According to Google, the _ga cookie is kept for about 2 years.
Purpose: counting visits, understanding which pages people read and where they came from, and recording an event when you successfully submit the contact form or the quote form. We do not send your name, email, phone number or anything you type into our forms to Google.
The website loads Google Analytics from your very first visit (opt-out model) and sets the _ga and _ga_FF8JP2EF4X cookies as described above. If you click “Reject”, Google Analytics stops immediately and is not loaded on later visits: no request is made to Google and no new Google cookie is set; Google cookies already set are also deleted from your browser. To turn it back on, use the “Cookie preferences” button in the footer and choose “Accept”.
Advertising Cookies (Meta Pixel)
Meta Pixel is an advertising measurement tool from Meta Platforms (Facebook, Instagram). Its script (fbevents.js) is loaded from connect.facebook.net and sets the _fbp cookie in your browser. According to Meta, the _fbp cookie is kept for about 90 days. The script also writes two entries to your browser local storage (lastExternalReferrer and lastExternalReferrerTime).
Purpose: measuring the effectiveness of our ads and visits (page views), and recording a "Lead" event when you successfully submit the contact form or the quote form. We do not send your name, email, phone number or anything you type into our forms to Meta.
The website loads Meta Pixel from your very first visit (opt-out model) and sets the _fbp cookie as described above. If you click “Reject”, Meta Pixel stops immediately and is not loaded on later visits: no request is made to Meta and no new _fbp cookie is set; the _fbp cookie already set is also deleted from your browser. To turn it back on, use the “Cookie preferences” button in the footer and choose “Accept”.
Managing Cookies
Use the “Cookie preferences” button in the footer at any time to reopen the cookie notice and change your choice. Choosing “Reject” stops the website using statistics and advertising cookies: these tools stop immediately, are not loaded on later visits, and cookies already set are deleted from your browser. You can also control or delete cookies through your browser settings; note that disabling some cookies may affect the functionality of the website.
