The calculator
The numbers you type are calculated in your browser and never sent to us.
Usage counts
We record anonymous events: that the page was opened, that the calculator was used, that the waitlist was seen and that someone joined it. Each record holds a random session ID that lives only in this browser tab, your country as reported by our hosting provider, the campaign tags in the link you followed and whether the link came from a Google ad. We do not store IP addresses and we do not set cookies.
The waitlist
If you ask for early access we store your email address, the platform you picked, the number of doses the calculator showed and the campaign tags above. We use your email only to tell you when early access opens. We do not sell or share it.
Where data lives
The site and its database run on Cloudflare.
Removing your data
