Cookie Notice
We barely use cookies. Almost everything that remembers you — your streak, your settings — lives in your own browser, not on our servers.
We don’t run advertising cookies or cross-site ad trackers — we don’t serve ads at all. Your streak and settings are kept in your browser’s local storage, which stays on your device. We do set two kinds of first-party cookie: one to keep you signed in if you have an account, and analytics cookies that help us count visits and understand how the games are played. Everything below just says that more carefully.
01 What a cookie even is
A cookie is a small file a site asks your browser to hold onto and hand back on your next visit. Local storage is a related tool that does much the same job but never travels back to the server on its own. Most of what Greatest Games remembers uses the second kind — it lives with you, not with us.
02 What we keep on your device
None of the following is a cookie in the traditional sense, and none of it leaves your browser unless you ask it to. We list it here because it’s the honest answer to “what does this site remember about me?”
- Game progress
- Your streak, completed games, and per-game stats — kept in local storage so your progress stays yours. No account required to hold it.
- Today's progress
- A small daily record so a half-finished puzzle is still there when you come back later the same day.
- Settings
- Preferences such as reduced motion, contrast, and a game's difficulty toggle. These sit in local storage and never leave your device.
03 The cookies we set
There are two kinds, both first-party. Signing in sets a session cookie — the strictly-necessary kind — so the site knows it’s still you on your next visit; until you create an account and sign in, no session cookie is set. Separately, our analytics provider (PostHog) sets first-party analytics cookies to recognise a returning visitor and stitch a single session together. We set no advertising cookies and no cross-site ad trackers ride along.
04 Analytics
To understand whether a puzzle landed, we record usage events — both to our own first-party log and to PostHog, a third-party analytics provider that processes the data for us. This includes session replay of how a page was used, with all text inputs masked so nothing you type is recorded. Events carry an anonymous device and session identifier, not your name — tied to your account only if you’re signed in. We never store raw IP addresses, your email, or anything you typed in this data. The full picture is in our Privacy Policy.
05 Managing & clearing
You’re in control of all of it. Clearing your browser’s site data wipes our local storage and any session cookie in one go — the games still play, you’ll simply start a fresh streak. Most browsers also let you block cookies entirely; the main thing that breaks is staying signed in.
The best cookie notice is the one you barely need, because there’s barely a cookie to explain.— Our standing aim
