Cookie policy
Last updated 21 October 2026.
This policy explains the cookies and similar technologies PulseStack™ uses on pulsestack.co.uk, and the choices you have. PulseStack™ is a trading name of AI Programs Holdings Ltd. The tables further down this page list every cookie we currently use, and they change automatically when we switch a tool on or off.
1. What cookies are
Cookies are small files a website saves in your browser. Similar technologies, such as pixels, tags and your browser's local storage, work in a similar way, and this policy covers them too. The law (the Privacy and Electronic Communications Regulations) lets us use the ones a site needs to work without asking, and requires your consent for the rest.
2. How we use them
Essential cookies keep you signed in, protect the sign-in forms and remember your cookie choices. The site cannot work without them, so they are always on.
Analytics cookies tell us how people use the site, for example which pages are visited, so we can improve it. We only use them if you allow them.
Marketing cookies tell us whether a visit, a free trial or a purchase came from one of our adverts, and let advertising platforms show our adverts to people who have visited. We only use them if you allow them. If you allow them and then start a trial or buy a plan or add-on, the advertising platform is also told about it; our privacy policy explains what is shared, including your email address in scrambled (hashed) form.
Nothing in the analytics or marketing groups loads until you choose. Google's tags are set up so that, until you agree, they do not run at all. None of these tools ever runs in our admin pages, or on the status pages our customers publish on PulseStack™.
3. Your choices
When you first visit, we ask which groups you are happy to allow. "Accept all" and "Reject all" are equally easy, and "Choose which cookies" lets you pick group by group. Rejecting non-essential cookies does not stop you using any part of the site.
You can change your mind at any time from "Cookie settings" at the bottom of every page. If you turn a group off, we delete the cookies we can and stop the tools in that group. We remember your choice for six months, then ask again. We also ask again sooner if we start using a new tool. We keep a record of each choice, without your IP address, for one year, so we can show we asked.
You can also block or delete cookies in your browser settings, though the site will not work properly without the essential ones. To manage the adverts Google shows you, visit Google's My Ad Center, and to stop Google Analytics on every website you can install Google's opt-out add-on.
4. Other technologies
When you pay or start a trial, you move to a secure checkout page run by Stripe, which sets its own cookies to prevent fraud; Stripe's cookie policy covers them.
Your dashboard remembers layout choices (such as a collapsed sidebar) in your browser's local storage. If you allow analytics or marketing cookies, we also keep a note there that a sign-up, trial or purchase has been reported, so it is not reported twice.
