Privacy
The short version
CO2Stats sets no cookies, runs no advertising and loads nothing from any other website: every file on every page comes from co2stats.com. We do not run analytics yet. We keep no record of who visits. If you register interest in the agency tier, we keep the email address you give, as set out below.
What happens when you visit
The site runs on Cloudflare. To deliver pages and protect the site from attack, Cloudflare processes the address your device connects from (its IP address) and the details your browser sends with each request. We do not store them, and we do not use them to identify you. Cloudflare explains its own handling in its privacy policy.
The Kettle calculator works entirely in your browser: what you type is never sent to us. The birth-year form sends the year to our server only so that it can show you that year’s page; the year is not stored.
If you email us
If you write to hello@co2stats.com, your message and address are held by our email and help-desk providers. We use them only to answer you and to keep a record of what was said, and delete them once we no longer need them for that.
If you register interest in the agency tier
If you leave your email address on the agency page, we store it with the version of the wording you agreed to and the time you agreed. We use it for one thing: to email you once, if and when the agency tier launches. Our lawful basis is your consent, which you can withdraw at any time by writing to us.
Only we can see the list. It is stored in our database at our hosting provider, Cloudflare, which keeps it on our behalf and does not use it. We keep each address for up to 12 months, or until that one email has been sent if sooner, and then delete it. Our hosting provider keeps backups for up to 30 days, so a deleted address leaves them within 30 days.
To have your address deleted sooner, write to hello@co2stats.com from that address, or tell us which address it is.
Why we may use it
Under UK data protection law, our lawful basis for serving the site and answering email is legitimate interests: ours in delivering the site and keeping it secure, and in answering the messages people send us. Neither uses more than the information described above, and neither is used for anything else.
What will change
Two things planned for the site will involve more than this, and this page will say exactly what each records, why and for how long before it starts: cookieless visitor counts, and the website carbon checker, which will store the address of each page checked and its result.
Who is responsible
CO2Stats is run by Achtung Ltd, 22 Wenlock Road, London N1 7GU, which is responsible for the information described here. Write to hello@co2stats.com.
Your rights
You can ask us what we hold about you, ask us to correct or delete it, ask us to restrict how we use it, or object to our using it at all, by writing to hello@co2stats.com. If you are unhappy with how we handle your information, you can complain to the Information Commissioner’s Office.
