Cookie policy

Last updated: 13 July 2026

1. Who we are

This website is operated by Brass Tacks, a trading name of Colossal Search Ltd (company number 08531647, registered in England and Wales). Registered office: Quarry Hill House, School Street, Farsley, Pudsey, West Yorkshire, LS28 5EY. Contact: ads@colossalsearch.com.

2. What cookies are

Cookies are small text files placed on your device when you visit a website. They help the site work, remember your choices, and — where you allow it — help us understand how the site is used and measure our own advertising. We use the word "cookies" here to cover similar technologies too, such as local storage and tracking pixels.

Cookies are either **first-party** (set by this site) or **third-party** (set by another company, such as Google). They can be **session** cookies (deleted when you close your browser) or **persistent** cookies (which last for a set period).

3. How we use cookies

We keep it minimal. Cookies on this site fall into three categories:

Strictly necessary cookies

These are required for the site to function — for example, to submit forms securely, prevent spam, and remember your cookie preferences. They don't need your consent and can't be switched off throughour settings.

CookieProviderPurposeDuration
wf-csrf and other Webflow functional cookiesWebflow (our hosting platform)Site security and form submissionSession
Cookie consent preferenceThis siteRemembers the choices you make in "Cookies Settings"Up to 12 months

Analytics cookies (only with your consent)

These help us understand how visitors use the site — which pages are read, where visitors come from — so we can improve it. The data is aggregated; we're not interested in following individuals around.

CookieProviderPurposeDuration

_ga_*Google Analytics 4Maintains session stateUp to 13 months

Advertising cookies (only with your consent)

We run paid advertising for a living, so yes — we use it ourselves, on Google and on Meta (Facebook and Instagram). These cookies measure whether our own ads brought you here and whether they led to an enquiry, and may be used to show you our ads elsewhere.

CookieProviderPurposeDuration
_gcl_auGoogle AdsConversion measurement (linking ad clicks to enquiries)3 months

_fbpMeta (Facebook/Instagram)Distinguishes browsers for ad measurement and remarketing3 months
_fbcMeta (Facebook/Instagram)Records that you arrived via a Meta ad, for conversion measurement3 months
frMeta (third-party, set by facebook.com)Ad delivery and measurement for logged-in Facebook users3 months

Analytics and advertising cookies are set only if you accept them via the cookie banner or "Cookies Settings". If you decline, the site works exactly the same — you'll just be invisible to our stats, which, as we tell our clients daily, is your right.

4. Managing your preferences

  • On this site: use the Cookies Settings link in the footer to review or change your choices at any time.
  • In your browser: all major browsers let you block or delete cookies — see your browser's help pages (Chrome, Safari, Firefox, Edge). Blocking strictly necessary cookies may stop parts of the site (such as the enquiry form) from working.
  • Google's own controls: you can opt out of Google Analytics via the GA opt-out browser add-on and manage Google ad personalisation at adssettings.google.com.
  • Meta's own controls: you can manage how Meta uses your activity from other websites at facebook.com/adpreferences (Ad preferences → Ad settings).

5. Third-party cookies and transfers

Cookies set by Google and Meta involve data being processed by Google LLC and Meta Platforms (Meta Platforms Ireland Ltd and Meta Platforms, Inc.), which may include transfers outside the UK. See our Privacy Policy (section on international transfers) for how those transfers are protected. Their own privacy policies are at policies.google.com/privacy and facebook.com/privacy/policy.

6. Changes to this policy

If we add or change the cookies we use, we'll update this page and the tables above, and refresh the date at the top. Significant changes will be reflected in the cookie banner so you can make a fresh choice.
