Kadenzo Cookie Policy
Last updated: August 2026
This page lists every cookie and similar technology used on kadenzo.app, what each is for, and how long it lasts. The product app at studio.kadenzo.app sets its own login cookies, which are covered by our Privacy Policy.
Your choice, and how to change it
We do not interrupt you with a cookie pop-up. The analytics and advertising cookies described below are on by default, and the button here is how you turn them off. We would rather say that plainly on the page you can act on than hide it behind a banner you have to dismiss before reading anything.
Switching a category off takes effect immediately and is remembered, so it applies on every later visit too — on studio.kadenzo.app as well, since the two share this choice. You can switch it back on here just as easily.
You can change or withdraw your consent at any time, and it takes effect immediately — withdrawing is exactly as easy as agreeing.
You can also block or delete cookies in your browser settings. Blocking the strictly necessary ones may stop parts of the site working.
Strictly necessary
These run the site and remember your cookie choice. They do not need consent, and cannot be switched off.
| Cookie | Purpose | Lasts |
|---|---|---|
| kadenzo_consent | Stores the cookie choice you made in the banner so we don't ask again. Set on kadenzo.app and shared with studio.kadenzo.app, so choosing once covers both — you are never asked twice. | 6 months |
| kadenzo_ga | Set only when you click through to checkout. Carries your analytics session across to studio.kadenzo.app so a signup can be attributed to the visit it came from. Written only if you have accepted analytics. | 10 minutes |
| Vercel platform cookies | Set by our host to route requests and protect the site from abuse. | Session |
Analytics
These tell us which pages are useful so we know what to write next, and which parts of our tools people get stuck on. We look at them in aggregate; we are not trying to follow individuals around.
One of them deserves spelling out. Microsoft Clarity replays sessions — it records the pages you open, where you scroll, and where you click or tap, and plays them back to us as an anonymous recording. It is how we find the button nobody can see and the tool that quietly fails. It is set to mask text and form fields, so what you type into a tool is not captured, and recordings are not tied to your name or email. Turn analytics off and nothing is recorded at all.
| Cookie | Purpose | Lasts |
|---|---|---|
| _ga, _ga_* | Google Analytics 4. Tells us which pages get read and how visitors move through the site, in aggregate. Not set until you accept analytics. | Up to 2 years |
| _clck | Microsoft Clarity. Holds a random ID so the pages you open in one visit are joined into a single session, and so a return visit is not counted as a new person. Not set until you accept analytics. | 1 year |
| _clsk | Microsoft Clarity. Groups the current visit's pageviews into one session recording. Not set until you accept analytics. | 1 day |
Advertising
We advertise Kadenzo on Google and Meta. These let us see which ads actually lead to signups, so we are not paying for ads that do nothing, and let us show ads to people who have visited before.
| Cookie | Purpose | Lasts |
|---|---|---|
| _gcl_* | Google Ads. Records that a visit came from one of our ads so we can tell which ads lead to signups. | Up to 90 days |
| _fbp | Meta Pixel. Measures whether our Facebook and Instagram ads lead to signups, and lets us show ads to people who have visited before. | Up to 90 days |
| MUID, CLID, ANONCHK, MR, SM | Set by Microsoft alongside Clarity. These identify a browser across Microsoft's own sites and services, which is why they sit here rather than under analytics. We only tell Microsoft it may set them if you accept advertising — accept analytics alone and Clarity still records your visit using the first-party cookies above, without these. | 10 minutes to 1 year |
Google, Meta and Microsoft act as independent controllers for some of this data. Their own policies apply alongside ours: Google, Meta and Microsoft.
