Cookie policy
Last updated: 31 August 2026
This policy explains the cookies and similar technologies Kelvo uses on our marketing site (usekelvo.com) and on organisation booking sites at *.kelvo.co, and how you control them. It should be read with our Privacy Policy.
The two categories we use
- Strictly necessary — required to run the site: signing in, keeping you signed in, and session continuity. These are set without consent because the service cannot work without them. You can block them in your browser, but parts of the site will break.
- Analytics (optional) — Google Analytics and Hotjar, to understand how the site is used so we can improve it. Hotjar also records anonymised replays of site visits and builds heatmaps of where people click and scroll. These are only set once you accept. Until then, and if you reject, no analytics cookies are stored.
Your choice, and how to change it
When you first visit we ask for your consent to analytics cookies. We use Google Consent Mode: analytics storage stays denied until you accept, and the Hotjar script is not loaded at all, so nothing is stored on your device beforehand. If you later withdraw consent we clear Hotjar’s cookies and stop the recording immediately. You can change or withdraw your choice at any time using the “Manage cookies”link in the footer — withdrawing is as easy as giving consent. Your preference is remembered in your browser’s local storage (itself strictly necessary).
Cookies we set
| Cookie | Category | Purpose | Retention |
|---|---|---|---|
| Authentication / session | Strictly necessary | Keeps you signed in and secures your session. | Session / up to 30 days |
_ga, _ga_<id> | Analytics (consent) | Google Analytics — distinguishes visitors and sessions to measure usage. | Up to 2 years |
_hjSession*, _hjSessionUser*, other _hj* | Analytics (consent) | Hotjar — ties a visit together for heatmaps and session replay. | Session / up to 1 year |
Google Analytics
We run two separate Google Analytics 4 properties: one for the marketing site and one for the organisation booking sites (*.kelvo.co). Analytics data is associated with the organisation whose site you are on so each organisation’s usage can be measured separately. Google acts as our processor for this data; see how Google uses data and the Google Analytics opt-out. We do not use Analytics for advertising or remarketing.
Hotjar
Hotjar gives us heatmaps and anonymised replays of site visits so we can see where people get stuck. Replays are pseudonymised: we suppress every form field on the site, so what you type — names, email addresses, payment details — is never recorded, and card details are handled inside Stripe’s own frames which are not captured at all. We never use replays to identify an individual. Hotjar acts as our processor and stores data in the EU; see the Hotjar privacy policy and their do-not-track / opt-out.
