Cookies
Last updated 19 August 2026
Two kinds of thing get stored in your browser here. The first keeps the app working — it is how you stay signed in. The second measures how the app is used, and none of it loads until you say it may: on a first visit the site asks, and until it is answered no measurement tag is on the page at all. Both kinds are listed in full below; there is nothing else.
Your choice
Measurement cookies
Google Analytics, Microsoft Clarity and PostHog — the three tags in the table above. The strictly necessary cookies are not covered by this switch: without them you cannot stay signed in, so there is nothing to choose.
Refusing clears the cookies the three tags set and switches them off. If they were already running on this page it also reloads it, because a script in the document cannot be taken back out of it.
Strictly necessary
Set by us. Without these, signing in and the free ask allowance do not work.
Keeps you signed in between page loads. Without it, saving a plant would end at the next navigation.
Kept: Until you sign out, or the session expires.
Remembers whether you allowed measurement, so you are asked once rather than on every page. Held in local storage rather than a cookie — asking permission to set cookies by setting a cookie would be a poor start.
Kept: Until you change it or clear site data.
Counts how many model-written answers the ask bar has given this browser today, so the free allowance can be shared out without anyone having to sign in for it.
Kept: 2 days.
Measurement
Set by third parties on our behalf. Refusing them costs you nothing on this site.
Counts visits and tells us which channel someone arrived from, so we know which material is worth writing more of.
Kept: Up to 2 years in the browser; 14 months in the Google property. · opt out
Records anonymised session replays and heatmaps of how the builder is used, so a control nobody can find gets fixed rather than argued about.
Kept: Up to 1 year in the browser; 30 days of recordings. · opt out
The product funnel — which steps of building a plant people complete and where they stop.
Kept: Up to 1 year in the browser. · opt out
These tags only load in the deployed app; a local or preview build does not send anything. Session replays are anonymised by the provider, and we do not attempt to re-identify anyone from them.
Other ways to switch it off
The control above is the direct route, and withdrawing there is exactly as easy as allowing. These work too, and work on every site rather than just this one.
- Send a Do Not Track or Global Privacy Control signal from your browser — most modern browsers and privacy extensions do this, and the tags above honour it where their own settings require them to.
- Block third-party cookies, or use the per-provider opt-outs linked in the table. The site works normally with all of them blocked.
- Clear the cookies for this site at any time from your browser’s settings. You will be signed out, and the site will ask about measurement again — those are the only effects.
- Or write to hello@climatewise.today and ask us to exclude you.
The wider picture — what is collected, who processes it and how long it is kept — is in Privacy.
