Cookie Policy
Last updated: October 1, 2026
This page lists the cookies and browser storage items this site uses, what each one is for, how long it lasts, and whether it depends on your choice. It works together with the Privacy Policy.
1. What cookies and storage are
Cookies are small text files a website places on your device. Browsers also offer "local storage" and "session storage", which work in a similar way. I refer to all of them here as cookies or storage items.
2. What this site sets
The last column says whether your analytics and advertising choice (see section 3) changes the item. Durations for third-party items are the ones published by the provider and can change. Items set only by the provider's own script are described as such.
| Name | Set by | Purpose | Duration | Affected by your choice? |
|---|---|---|---|---|
cookieConsent (local storage) | This site | Remembers your analytics and advertising choice so you are not asked again | Until you clear site data | No, it records the choice itself |
az_lead (session storage) | This site | Keeps the name and email you typed in the booking form, and a random identifier for that submission, so the booking page can show them and the thank-you page knows the booking came from the form | Until you close the browser tab | No, the booking flow needs it |
az_booked (session storage) | This site | Marks that you told the booking page your call is booked, so the thank-you page can show | Until you close the browser tab | No |
az_fired (session storage) | This site | Remembers which booking and lead events were already reported in this tab so none is reported twice | Until you close the browser tab | No |
az_attr (session storage, local storage and a cookie) | This site | Records where your first visit came from: campaign tags (UTM), ad click identifiers, referring page and landing page, so the booking form can carry them | Cookie: 30 days. Local storage copy: kept until replaced or you clear site data, and treated as expired after 30 days. Session storage copy: until you close the browser tab | Yes. It is not written while you are opted out, and if you opt out it is deleted from all three places |
| Google Tag Manager | Loads the other tags on this list. It does not set cookies of its own | Not applicable | The tags it loads receive your choice as a Google consent signal | |
_ga, _ga_* | Google Analytics 4 | Tells visits and visitors apart and measures how the site is used | Up to 2 years | Yes. Google receives a denied consent signal, and under Google's consent mode may still send limited pings that do not use cookies |
_clck, _clsk, CLID, MUID (and possibly others) | Microsoft Clarity | Session recordings and heatmaps, and recognising a returning browser | From 1 day (_clsk) to 1 year (_clck, CLID, MUID), per Microsoft | Yes. Clarity is told to stop recording |
__oppref | OpenAI advertising pixel (a cookie on this site, set by OpenAI's script; my code only reads it) | Holds the ad click identifier so a later lead can be matched to the ad. Present only if you arrive from an OpenAI ad and the pixel has run | Set by OpenAI | Yes. The pixel does not load while you are opted out |
| Other OpenAI pixel storage | OpenAI | The pixel may keep additional identifiers to measure ads. See OpenAI's own documentation for the current list | Set by OpenAI | Yes. The pixel does not load while you are opted out |
Calendar on /book-a-call | Google Calendar appointment scheduling | Runs the calendar where you pick a time. Google may set its own cookies while it is shown | Set by Google | No. Google's own policy applies |
az_ch_jwt, az_ch_user (local storage) | This site, client portal only | Keeps you signed in to the client portal (sign-in token and basic profile). Set only if you sign in | Until you sign out or clear site data | No, the portal needs it |
lsn-read-* (session storage) | This site, client portal lessons only | Remembers that you marked a lesson as read in this tab | Until you close the browser tab | No |
The booking and snapshot forms send their content to my own automation, CRM, Gmail and Telegram when you press send. That does not add a cookie to this site. The newsletter sign-up and the older contact and article forms send to Formspree instead, which is a third-party form service; I set no cookie for it, and Formspree's own policy applies to what it receives. If I switch on Cloudflare Turnstile, a bot check on forms, Cloudflare's own policy applies to it. Some older pages also load fonts and scripts from Google Fonts, Cloudflare (cdnjs) and jsDelivr, whose servers see your IP address.
3. Changing your choice
You can opt out of analytics and advertising measurement, or opt back in, at any time on the privacy choices section of the Privacy Policy, or with the Cookie choices button in the footer. What each choice does is described there. You can also delete cookies and site data in your browser settings, or block them, although parts of the site may then behave differently.
Before you choose, analytics and ad measurement are allowed, except where they stay off until you press Accept: when your browser sends the Global Privacy Control signal; when your time zone is in Europe (any Europe/ zone, or Atlantic/Azores, Atlantic/Madeira, Atlantic/Canary, Atlantic/Faroe, Atlantic/Reykjavik, Africa/Ceuta, Asia/Nicosia, Asia/Famagusta or Arctic/Longyearbyen); or when your time zone is UTC, GMT or unknown and your browser language is an EU, EEA or UK language. Your own choice always wins over these defaults.
4. Global Privacy Control and Do Not Track
This site treats the Global Privacy Control signal as an opt-out, as described above. It does not respond to the older "Do Not Track" browser signal; use the privacy choices link instead.
