Privacy policy

The short version: the calculators run entirely in your browser. Nothing you select, type or calculate is sent to us or anyone else.

What we collect

Calculator usage: nothing. Selections (Town Hall level, builder count, buildings) are processed in your browser only and vanish when you close the tab. There is no account, no save, no upload.
Analytics: none. This site ships no analytics scripts, no trackers and no advertising cookies.
Server logs: our host (Cloudflare) processes standard request logs (IP address, URL, timestamp) for security and abuse prevention, as any web host does. We do not use them to profile visitors.
Email: if you write to us, we keep your message and address to reply and to fix the issue you reported. We never send bulk mail or share addresses.

Cookies

This site sets no cookies of its own. If Cloudflare serves a technical cookie to protect against abuse, it is strictly functional and requires no consent banner.

Your rights

Because we collect no personal data beyond the email you optionally send us, there is no profile to export or delete. To have a message deleted from our inbox, mail hello@coccalc.top and we will remove it.

Changes

If this policy ever changes (for example if analytics or ads are added), the change and its date will be posted here and in the changelog before it takes effect.
