What this site loads
nadcost.com loads one analytics vendor: Google Analytics 4, operated by Google. It is loaded from googletagmanager.com on every page and reports to google-analytics.com. It tells us which pages are read, how readers arrive, and roughly where in the world they are.
That is the complete list. There is no tag manager, no advertising pixel, no session recorder and no third-party embed. The only other third-party requests these pages make are for the two typefaces.
Google Analytics runs here with advertising features switched off: Google Consent Mode is set to deny ad_storage, ad_user_data and ad_personalization on every page load. Nothing measured here builds an advertising audience or targets you anywhere else.
Google Analytics sets two cookies, _ga and _ga_<stream>, holding a random identifier for the browser rather than for you. They are the only cookies this site sets.
Turning analytics off
Analytics is on by default and starts when the page loads. This is a US-audience site and we treat it as an opt-out, not an opt-in: a notice tells you it is running, and one click switches it off, here or from the notice. Switching it off also deletes the two cookies already on this device.
Checking your current analytics setting…
We also honour Global Privacy Control. If your browser or an extension sends that signal, analytics is off for you automatically and you need not click anything. Your choice lives in this browser only, so clearing site data resets it and another device is a separate decision.
What the site stores about you
No account, no newsletter, no comment form, no contact form, and no name or email address anywhere. What Google Analytics holds is the anonymous browser-level measurement described above; your analytics choice itself is kept in this browser’s local storage under cookie-consent, which is not a cookie and is never sent to us. The calculator runs entirely in your browser: the numbers you type are never sent anywhere, are not saved, and are gone when you close the tab.
What happens when you follow a paid link
Links to providers leave this site through an internal redirect at /go/. When the provider is one that pays us, that redirect adds identifiers to the destination URL saying which provider was clicked, which page the click came from and which position on that page. It carries no identifier for you. When the provider does not pay us, the redirect adds nothing at all.
Once you arrive, you are on the provider’s site under the provider’s privacy policy, which we do not control and are not responsible for. The affiliate network that records the click may set its own cookie; that is described in the network’s policy, not ours. What we receive back is a count of clicks and conversions, never a person.
Server logs
The host serving this site keeps ordinary request logs, which include IP addresses, for security and abuse purposes. We do not use them to build profiles and we do not combine them with anything else.
Children
This site is not directed to children under 13 and asks nothing of anyone.
Your choices
We hold no account and no identifier for you, so there is generally nothing to request, correct or delete. What exists is the anonymous analytics above, and you can switch it off at any time under Turning analytics off. If you believe we hold something about you, write to editor@nadcost.com and we will answer.
