Cookie policy
Contents
Analytics and marketing tools load only after you say yes, and never on private pages (our client workspace, proposal and invoice links, unsubscribe). Change your mind any time with Cookie settings; when you withdraw, we delete the cookies those tools left on this site.
Categories
| Category | What it does | Tools | Default |
|---|---|---|---|
| Essential | Runs the site, keeps it secure, and remembers your cookie choice and settings. | Rhytmelo; Cloudflare | Always on |
| Analytics | Shows how the site is used, including session recordings in which what you type into forms is hidden. | Google Analytics 4, Microsoft Clarity, Contentsquare | Off until you say yes |
| Marketing | Measures our ads and shows which companies visit, so we can follow up with businesses that showed interest. HubSpot recognises a returning visitor and links visits to your enquiry if you send us a form. If you then send a sales form, Meta receives a hashed copy of your email and phone (see our privacy policy). | Google Ads, Meta (pixel and Conversions API), Apollo.io, HubSpot | Off until you say yes |
Contentsquare and Apollo.io load through Google Tag Manager, which we load only when you allow both analytics and marketing. For what Meta and Apollo.io receive, see our privacy policy.

Lifetimes were measured on rhytmelo.com on 25 October 2026 (_clsk and _fbc from the providers’ documentation: they appear only after page activity or a click on a Meta ad; the HubSpot lifetimes also come from HubSpot’s documentation). Cookies set on a provider’s own domain (clarity.ms, apollo.io, doubleclick.net) can only be removed by that provider or in your browser settings. Providers can change names and lifetimes; we check this list against the live site whenever we update this policy.
What we don’t do
- No analytics or advertising tool loads before you choose.
- Our fonts are served from rhytmelo.com, so your browser makes no request to Google Fonts.
- No analytics or advertising tool runs on private pages: our client workspace, proposal and invoice links, and unsubscribe pages.
Global Privacy Control
If your browser sends the Global Privacy Control signal, we treat it as a “no” to marketing, whatever you click. Analytics still follows your choice.
Proof of your choice
We keep a record of each choice (a random ID, what you chose, when, on which page and under which policy version) for 2 years, so we can show we had your consent. The record doesn’t include your name, and we don’t add your IP address to it.
How to change your choice
Use “Cookie settings” in the footer of any page, or the button on this page, to accept, reject or choose by category. Rejecting is as easy as accepting. When you withdraw a category, we delete the cookies and browser storage it left on this site. You can also delete cookies in your browser settings.
For how we use the data these tools collect, see our privacy policy.
