This page lists every cookie and similar item our websites keep in your browser: who sets
it, what it is for and how long it lasts. Necessary ones are always on. Analytics and Ad
measurement are off unless you allow them.
A first-party cookie is stored under our own web address. The company named still receives
what it measures. A lifetime is the longest a cookie can last; your browser may delete it
sooner.
Necessary
These keep our websites working and remember settings you chose. They are always on, so we don't ask about them.

Changing your choice
Use Cookie settings at the bottom of any page, or in the menu and on the
Profile page of your LineHQ account. Your choice applies on linehq.co.uk and
app.linehq.co.uk. If you withdraw a yes, those tools stop straight away and we remove their
cookies from your browser.
If your browser sends a Global Privacy Control or Do Not Track signal, we treat it as no to
both until you choose otherwise in Cookie settings.
When you save a choice, we keep a record of it: a random ID, your answers, the page and the
time. It holds no name, IP address or account details. It lets us show what was agreed.
Our Privacy Policy explains what we do with the
data and which companies receive it.
