Cookie Policy
Last updated: October 31, 2026
1. Essential Cookies
Needed for the site to work or to remember a choice you made. They do not require consent.
| Name | Purpose | Duration |
|---|---|---|
| auth-token | Keeps you signed in. | 1 hour, renewed while you use the site |
| hasAuth | Tells the site you are signed in. | Until you close the browser |
| oauth-state | Protects signing in with Google. | 10 minutes |

| announcement-dismissed | Hides a site announcement you closed. | 14 days |
Cloudflare, which protects the site, may also set short-lived security cookies to tell visitors from bots. Some tools save drafts, your saved decks and the player tag you entered in your browser's local storage; that data stays on your device.
2. Analytics Cookies
Google Analytics and PostHog help us understand how you use the site and fix usability problems. PostHog includes maps of clicks and scrolling, and recordings of page interactions. Form inputs and private content are hidden in recordings.
- In the European Economic Area, the United Kingdom and Switzerland analytics is off until you allow it. We use your IP address to determine your country; if it is unknown, we also keep analytics off until you allow it.
- Everywhere else they are on by default, and you can turn them off at any time.
| Name | Set by | Duration |
|---|---|---|
| _ga, _ga_<ID> | Google Analytics 4 | 2 years |
| ph_<key>_posthog | PostHog (EU) | 1 year |
Turning analytics off stops this collection, including recordings. We do not use advertising cookies; if that changes, we will update this page and the cookie banner first.
3. Changing Your Choice
You can allow or turn off analytics at any time with the Cookie Settings link at the bottom of every page, or delete cookies in your browser settings. More about how we handle data in our Privacy Policy. Questions: [email protected].
