No account, ever
You never sign up. Gen Sizer doesn't ask for a name, an email, or a password, and there is no profile being built behind the scenes. "No email required" isn't a marketing line on this site — it's how the tool is built.
Everything happens in your browser
The appliance wattage table ships to your browser as part of the page, and the sizing math — running watts, startup peak, the kW verdict — runs right there using the page's own code. Nothing you tick is uploaded. Today the page runs no analytics script and no tracking pixel.
Nothing is stored, anywhere
Gen Sizer goes further than most tools: it doesn't even use your browser's storage. Your checked boxes live only in the memory of the open tab. Close the tab or reload the page and the picker starts fresh — there is no history, no saved list, and nothing on our servers either. Nothing to clear, because there was nothing kept.
The hosting, honestly
The site is hosted on Cloudflare. When you open a page, Cloudflare keeps its standard technical logs — things like your IP address, browser type, and which page was requested — which is how any hosted site delivers pages and fends off abuse. That is the whole server-side record of your visit.
Ads: a placeholder today, Google's cookies when they arrive
The page carries an empty ad slot — no ad code runs yet. When ads are switched on, they will be served by Google AdSense. From that day, Google and its partners may use cookies to choose which ads you see, based on your visits to this and other sites. You can control that in Google's ads settings or block cookies in your browser settings; the sizer itself keeps working with cookies off.

Questions go to [email protected]. The email address you write from is used only to answer you — and asking gets the thread deleted.
- No account, no sign-up, and nothing about you collected by the tool.
- The sizing math runs entirely in your browser; nothing you tick is uploaded.
- Nothing is stored — not on our servers, not on your device. Reload and the page is blank again.
- The host, Cloudflare, keeps standard technical logs for every website visit.
- No ads run yet; when they do, Google's cookie handling comes with them.
