Cookie policy

Nanofuze.com itself sets no sign-in cookies. Signing in on the learning site (learn.nanofuze.com) sets cookies that are strictly necessary, so they need no consent: a secure session cookie (nf_session) that keeps you signed in for up to 30 days, a short-lived cookie (nf_oauth, ten minutes) that protects the sign-in from forgery while you are on Google's page, and a display cookie (nf_user) with your name and email address so the page can show whose account it is. Signing out removes all three.

These items are saved in your browser's local storage so the site can do what you asked: keep your theme, your animation setting, and this cookie choice. They are set only when you use those features, stay on your device, are never sent to Google and are never used to track you. Because the site cannot remember your settings without them, they need no consent. You can clear them at any time in your browser settings.

• nanofuze-analytics: whether you accepted or declined analytics, and when you chose. You are asked again after about six months.
• nanofuze-theme: whether you chose the light or dark theme.
• nanofuze-motion: whether you switched animations off (the footer switch).
• The learning site (learn.nanofuze.com) keeps its own settings and study data in your browser (course progress, review cards, notes, assistant voice); they are listed in its own cookie policy and never leave your device.

Google Analytics sets these cookies on Nanofuze only after you allow analytics. Until then nothing is requested from Google. They tell visits apart and keep a visit together; they are not used for advertising. The same analytics also measure clicks, scrolling, searches, forms, the assistant and page speed, as described in the Privacy policy, and never what you type.

• _ga: tells returning visitors apart. Lasts 13 months.
• _ga_X1W5KNQE2V: keeps the state of a visit. Lasts 13 months.

Choose Cookie settings in the footer of any page to switch analytics on or off again. Turning it off removes these two cookies and stops all measuring straight away. Necessary storage stays on, because the site needs it to remember your settings. You can also delete everything in your browser settings.

Apart from Google Analytics when you accept it, we do not embed third-party widgets, advertising or social media scripts, so no other third party sets cookies through Nanofuze.
