Cookies

This page lists what this website sets in your browser, who sets it, what it is for and how long it lasts. We ask before turning on anything beyond what the site needs to run, and this page is where you can check what that choice covers.

What we set and why

When you first visit, a banner asks you to accept cookies or accept essential only. Choosing "Accept cookies" turns on Google Analytics, Microsoft Clarity and our Meta (Facebook) advertising pixel, which help us understand how the site is used and how our adverts perform. Choosing "Accept essential" keeps those off; the cookie below marked essential is set either way, because it is what makes our AI chat assistant work at all. You can change your mind at any time by clearing your browser's site data for this domain and reloading the page.

Turning on Microsoft Clarity also sets a group of Microsoft cookies (MUID, SRM_B, MR and ANONCHK, below) that Microsoft's own documentation describes as part of its advertising and cross-site identity infrastructure, alongside their analytics use. Clarity sets these automatically as part of its script, as a side effect of running Clarity rather than of any advertising tag on this website: this website carries no Bing or Microsoft advertising tag, and we cannot switch off Microsoft's advertising use of these cookies while keeping Clarity's analytics.

The Meta pixel sets _fbp, which Meta describes as an advertising cookie. We use it to measure and improve our own Facebook and Instagram adverts; we do not describe it as analytics, and it only loads once you accept.

Every cookie measured on this website, and the purpose and lifetime of each.
Cookie Set by Purpose Lifetime
_ga Google Analytics
.dayonemartialarts.com
Counts you as one returning visitor across pages and visits, so we can see roughly how many people use the site. 400 days
_ga_01BHBXSNL9 Google Analytics
.dayonemartialarts.com
Google Analytics 4's record for this specific website property, used alongside _ga to build visit and session counts. 400 days
_clck Microsoft Clarity
.dayonemartialarts.com
Identifies you as one visitor to Microsoft Clarity, so the session recordings and click maps we use to see how the site is actually used can be grouped by visitor rather than by single page view. 365 days
CLID Microsoft Clarity
.clarity.ms
Clarity's own visitor identifier, used alongside _clck for the same purpose. 365 days
_clsk Microsoft Clarity
.dayonemartialarts.com
Groups your page views into a single Clarity session. It expires quickly, so a new visit starts a fresh session. 1 day
MUID Microsoft
.bing.com and .clarity.ms
Microsoft's own published description: identifies your browser across Microsoft's sites, and is used by Microsoft for advertising, site analytics and other operational purposes. Clarity uses it to link your visit into one session; the advertising use belongs to Microsoft, not to us. This website carries no Bing or Microsoft advertising tag; this cookie is set here as a side effect of the Clarity script. 390 days
SRM_B Microsoft (Bing)
.c.bing.com
Set on Microsoft's bing.com domain alongside MUID. We have not found a Microsoft-published description naming this specific cookie; independent cookie audits place it in Microsoft's advertising and targeting cookie set rather than analytics. This website carries no Bing or Microsoft advertising tag; it arrives here as a side effect of the Clarity script, and we cannot say more than that with confidence. 390 days
MR Microsoft
.c.bing.com and .c.clarity.ms
Microsoft's own published description: indicates whether to refresh MUID, the identifier above. 7 days
SM Microsoft Clarity
.c.clarity.ms
Microsoft's own published description: used in synchronising MUID across Microsoft's domains. Session
ANONCHK Microsoft Clarity
.c.clarity.ms
Microsoft's own published description: indicates whether MUID is transferred to ANID, a cookie used for advertising. Clarity does not use ANID, so this is always set to 0. Session
_fbp Meta (Facebook) pixel
.dayonemartialarts.com
Meta's own published description: an advertising cookie used to identify browsers for the purpose of delivering and measuring adverts across Meta's platforms. This is an advertising cookie, not an analytics one, and we only load the pixel that sets it once you accept. 90 days
__cf_bm Cloudflare, for our AI chat assistant
.leadconnectorhq.com
Bot management for our AI chat assistant's provider: it tells them a request is a real browser and not an automated attack. Strictly necessary, so it is set before any cookie choice is made. Session

Our AI chat assistant

Our AI chat assistant always loads on this site, whatever you choose in the cookie banner, so that anyone can talk to us straight away without first accepting cookies. The assistant's provider sets the __cf_bm cookie listed above for bot protection before you make any choice. That cookie is not something we can switch off and still offer a working chat, and we are not describing the widget as cookie-free: it does set a cookie, and this is what it is for.
