Cookie Policy
Last updated: 2026-09-25
Effective Date: 25/09/2026
What this covers
This page lists the cookies and similar technologies used on duellix.com, what each one does, and who sets it. It sits alongside our Privacy Policy, which explains more broadly how we handle personal data.
Your choice
What happens on your first visit depends on where you are.
If you are in the European Economic Area, the United Kingdom or Switzerland, we ask before setting anything beyond the strictly necessary cookies. Nothing in the Analytics or Marketing categories below is set until you agree, and refusing is a single click.
Everywhere else, including Singapore, the Analytics and Marketing cookies below are set when you arrive, and this page and our Privacy Policy are your notice of that. You can switch them off at any time, and we honour that choice for six months before asking again.
In either case, the Cookie settings link in the footer of every page shows what is currently on and lets you change it. If you switch the optional cookies off, the site works exactly as it otherwise would. The only difference is that we cannot tell which advert or search brought you here.
Strictly necessary
These are required for the site to function and are set without consent, as the law allows.
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
| dx_consent | Duellix (first party) | Remembers your cookie choice so we do not ask on every page. | 6 months |
Analytics
These tell us how the site is used, so we know which pages are worth improving. Set with your consent in the opt-in regions above, and on arrival elsewhere unless you switch them off.
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
| _ga, _ga_<id> | Google Analytics | Distinguishes visitors and sessions so visits can be counted. | 2 years |
Marketing
These tell us which advert, campaign or search brought someone to the site, so we can judge what our advertising is achieving. Set with your consent in the opt-in regions above, and on arrival elsewhere unless you switch them off. Google may also use its advertising cookies to personalise the adverts it shows you elsewhere; switching off Marketing stops that on our side.
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
| dx_attr | Duellix (first party) | Remembers which advert or campaign you arrived from, and a short reference code, so that an enquiry you send later can be matched to it. Not shared with anyone else and not used to track you across other websites. | 90 days |
| Google Ads cookies | Measures whether an advert led to an enquiry. | Up to 2 years |
Cookies set by other services
Some pages embed services run by other companies, which set their own cookies once you use them. Our forms are provided by Fillout and our call booking by TidyCal. Their own privacy notices govern what they store.
Managing cookies in your browser
Besides the choice offered on this site, every major browser lets you block or delete cookies in its settings. Doing so affects all websites, not only this one, and may stop parts of some sites working.
Changes
We update this page when the cookies we use change. The effective date above shows when it was last revised.
