Cookie Policy
Last updated 1 July 2026
This policy explains the cookies and similar technologies used on alderstonemedia.com by Alderstone Media Ltd. Read it together with our Privacy Policy. We set non-essential cookies only with your consent, as required by the Privacy and Electronic Communications Regulations 2003.
1. What these technologies are
A cookie is a small text file stored on your device by your browser. Similar technologies include tracking pixels, local storage entries and device fingerprinting techniques. Where this policy says "cookies" it means all of them.
Cookies set by us are first party; those set by another organisation whose service appears on our pages are third party. Session cookies expire when you close the browser; persistent cookies last for a stated period.
2. Strictly necessary
These make the site work and are exempt from the consent requirement.
| Name | Provider | Purpose | Expires |
|---|---|---|---|
| am_consent | First party | Records your cookie choices so the banner is not shown repeatedly | 12 months |
| am_csrf | First party | Protects forms against cross-site request forgery | Session |
3. Analytics
Set only with consent. We use aggregated analytics to understand which pages are useful and where visitors give up.
| Name | Provider | Purpose | Expires |
|---|---|---|---|
| _ga | Google Analytics 4 | Distinguishes visitors for aggregate reporting | 24 months |
| _ga_<ID> | Google Analytics 4 | Holds analytics session state | 24 months |
| _clck / _clsk | Microsoft Clarity | Anonymised interaction recording to diagnose usability problems | 12 months / session |
4. Advertising and measurement
Set only with consent. We advertise our own services on a small scale and measure the response.
| Name | Provider | Purpose | Expires |
|---|---|---|---|
| _gcl_au | Google Ads | Conversion attribution for our own advertising | 90 days |
| bcookie / li_sugr | Measures our LinkedIn campaigns and content | Up to 12 months |
We do not use cookies on this website to build audiences for our clients' campaigns. Client campaign measurement happens on the client's own properties, under the client's own notices.
5. Functional
| Name | Provider | Purpose | Expires |
|---|---|---|---|
| VISITOR_INFO1_LIVE / YSC | YouTube | Playback preferences for embedded case-study video, set when you press play | 6 months / session |
Providers control these names and durations and may change them. We review this table quarterly.
6. Giving and withdrawing consent
On your first visit you are asked to accept or reject non-essential cookies. Rejecting them does not restrict any content on this site. To change your mind, clear this site's cookies in your browser and reload the page — the banner will reappear.
Browser-level controls are available in Chrome, Firefox, Safari and Edge. You can opt out of Google Analytics on every site with the official browser add-on.
7. Global Privacy Control
We honour the Global Privacy Control signal where our consent tool detects it, treating it as a refusal of all non-essential cookies. We do not act on browser "Do Not Track" headers because no agreed standard exists for interpreting them.
8. Changes and contact
We revise this policy whenever the technologies we use change. Questions to [email protected] or Alderstone Media Ltd, Second Floor, 41 Corn Street, Bristol, BS1 1HT, United Kingdom.
