Privacy policy
Analytics only if you say yes.
Fizlet has no accounts and sells nothing. Analytics runs only if you accept it, and there are no ads. This page says what is collected, why, for how long, who processes it and how to opt out.

Who we are
Fizlet is an open-source (MIT) micro game and animation engine for the DOM, made by Chris Cooley under the coded.design ↗ name. "We" means the people behind that project. This policy covers fizlet.com. The games have their own site, DOM VIRUS ↗, with its own policy.
What we collect
Nothing that identifies you by name. There is no sign-up, no login and no form. The demos run in your browser and send nothing of their own.
Analytics, only if you say yes
On your first visit a banner asks. Choose Accept and the site loads Google Analytics 4 and PostHog. Choose Reject, or do nothing, and neither loads: no analytics script, no request and no analytics cookie.
What they collect: the pages you view, the site that sent you, your browser, device type, screen size and rough location (country or city, worked out from your IP address).
Why: to count visits and see which docs, bricks and demos people use, so we know what to fix and write next. We do not use it for advertising, remarketing or profiling, and we never sell it.
How long: we set Google Analytics to keep event data for 14 months. PostHog keeps event data for the retention period of our PostHog plan. The cookies they set are listed, with their lifetimes, on the cookies page.
Who processes analytics data
Google LLC runs Google Analytics 4. Google signals and ad personalisation are off, and the consent signals for advertising (ad storage, ad user data and ad personalisation) stay denied, so the data is not used for Google ads.
PostHog Inc. runs PostHog on its US cloud. Session recording and automatic click capture are off.
Both act as our processors and may handle data in the United States, under their own policies: Google ↗ and PostHog ↗.
Hosting and request logs
The site is hosted on GitHub Pages. Like any web host, GitHub receives the details every browser sends with a request, such as your IP address, and may log them under its own privacy statement ↗.
How to opt out
Choose Reject in the banner, or open Cookie settings at the foot of any page and untick Analytics. The site then stops both tools on the page and deletes their cookies.
If your browser sends Global Privacy Control or Do Not Track, we treat it as a Reject until you choose otherwise. A content blocker also stops the analytics scripts; the site works the same without them.
To ask us to delete analytics data about you, open an issue or use the private contact on GitHub ↗.
Children
The site is for a general audience and asks nobody for personal information, children included.
Changes to this policy
If what we collect changes, we update this page and its date first. Every change is public in the site's GitHub history ↗.
