- No cookies. This site sets none.
- Nothing saved in your browser. We don't use your browser's local or session storage.
- No accounts and no sign-up.
- The calculator runs in your browser. Your week is never sent to us; it lives only in the URL after the # sign, which browsers don't send to servers. Share the link and you share the week.
- Hosting: Cloudflare hosts the site and, like any web host, processes requests to deliver pages.
- Affiliate clicks go through a cookie-free /go/ redirect that logs the time, site, partner, source page path, the referring URL (without its query string), the browser user-agent string, country and network name, so bot clicks can be filtered out. No IP address, no cookies.
- Cloudflare Web Analytics (cookie-free) is used only if we enable it; it is not enabled right now.
