Cookies and storage

Last updated: November 10, 2026

We use as few cookies as we can. The ones below keep your game and your sign-in working; analytics cookies are used only as described.

Needed for the game

Name	Type	What it does	How long
`mf_sid`	Cookie	A random guest ID that keeps your saved game together.	13 months
`mf_auth`	Cookie	Keeps you signed in, only if you have an account.	13 months, or until you sign out
`mf_src`	Cookie	Remembers how you first found us (for example a search engine, a link from a friend or "direct"), so we can see which ways of finding the game bring players back. It holds no ID and nothing about who you are.	13 months
`mf_g`	Cookie	Protects "Continue with Google" while you sign in.	10 minutes
`mf-save-v1`	Local storage	Your saved game in this browser, so it works even offline.	Until you clear site data
`meadow-and-feather`	IndexedDB	Photos you take in the game, and postcards friends sent you. Your photos stay on your device, except one you choose to send to a friend as a postcard: a small copy then passes through our server and is deleted when your friend opens it, or after 30 days.	Until you clear site data

Analytics

Name	Type	What it does	How long
`_ga`, `_ga_*`	Cookie (Google Analytics)	Counts visits and pages. In the EU, the EEA, the UK and Switzerland only after you press OK.	Up to 2 years
`ga-consent`	Local storage	Remembers your choice in the cookie bar.	Until you clear site data

Google Analytics is active on this site.

Advertising cookies

There are none today. When ads arrive, our ad partner will use its own cookies, and we will list them here and in our privacy policy first, with a way to opt out.

Your control

You can block or delete cookies in your browser settings. Blocking mf_sid means your game is kept only in this browser's storage; clearing site data removes your game and photos from this browser.
