In short: NVDRA Calculator sets two technical cookies and keeps one setting in your browser. There are no advertising, analytics or tracking cookies, so there is nothing to opt out of.
What cookies and browser storage are
Cookies are small text files a website stores in your browser. “Local storage” is similar storage that stays on your device and is not sent to our servers.
