Cookie Policy

Last updated: 11 June 2026 · M365Clarity (Stephen Bennett, sole trader)

Short version: M365Clarity uses no advertising or analytics cookies. We use only essential technical cookies. Your session is stored in your browser's localStorage, not in a cookie.

What is a cookie?

A cookie is a small text file stored in your browser by a website. Cookies can remember your preferences, keep you logged in, or track your behaviour across sites.

M365Clarity uses your browser's localStorage — not cookies — to store your session token. localStorage is not transmitted to servers automatically the way cookies are, and it does not require consent under UK PECR.

Cookies we use

The following cookies may be set when you use M365Clarity:

Cookie name Provider Purpose Type Duration
__cf_bm Cloudflare Bot management and fraud prevention. Set by Cloudflare to distinguish between humans and automated bots, and to protect the site from malicious traffic. Essential 30 minutes
__cflb Cloudflare Load balancing. Ensures requests from the same user are routed to the same data centre during a session. Essential Session
esctx-* Microsoft Microsoft OAuth authentication session. Set by login.microsoftonline.com during the Microsoft 365 sign-in process. These cookies are set on Microsoft's domain, not m365clarity.com, and are outside our control. Essential Session
MUID Microsoft Microsoft user identifier used during authentication. Set on Microsoft's domain. Essential 13 months

What we do NOT use

M365Clarity does not use:

localStorage (not a cookie)

When you sign in to M365Clarity, your session token is stored in your browser's localStorage under the key token. This is technically distinct from a cookie:

To remove it, sign out of M365Clarity or clear your browser's site data for m365clarity.com.

Your consent choices

Because all cookies used by M365Clarity are strictly necessary for the service to function, they are exempt from consent requirements under UK PECR Regulation 6(4). You do not need to accept them — they are used automatically as part of providing the service.

We display a cookie notice on first visit to be transparent about our practices. Clicking "Accept all" or "Reject optional" both record your acknowledgement. Since we have no optional cookies, the functional outcome is the same either way.

How to control or delete cookies

You can control cookies through your browser settings:

Note that blocking essential cookies will prevent M365Clarity from functioning correctly — specifically, the Microsoft OAuth sign-in flow will not complete.

Changes to this policy

If we introduce new cookies (for example, if we add an analytics tool), we will update this policy and re-display the consent notice. We will not introduce non-essential cookies without providing a genuine choice.
