Privacy

There is no account and no sign-up, so we never ask for your name, email or anything else that identifies you. This page says exactly what is stored anyway.

What stays in your browser

Your progress lives in your own browser's local storage and never leaves it unless you play online. It holds your rating and record, which characters you have unlocked, your language and sound preference, your daily-game streak, and a random identifier the game generates for itself.

That identifier is a random string. It is not derived from you, your device or your network, and it cannot be linked back to you. Clearing your browser's site data for this site erases all of it, including the identifier.

What reaches our server

We run one server function, on Supabase. It receives:

• Online matches. While you play against another person, the server holds the board and the cards each side placed. It knows the two random identifiers of the players in that match and nothing else about you. Matches older than a day are deleted.
• Daily game scores. Your score on the shared daily game, so the page can say how you did against everyone else who played it. One row per identifier per day.
• Anonymous usage counts. Which screens were reached and how many games were started and finished, so we can tell whether the game is worth continuing. Values are capped at short primitives; free text is never sent.

None of this includes an IP address, a name, an email, or anything you typed. We do not sell it, and we do not share it with anyone.

Advertising

This site shows ads from Google AdSense. Google may set cookies or read device identifiers to choose and measure ads, which is outside our control and covered by Google's own policy. You can turn off personalised advertising at Google Ad Settings.

Hosting

The site is served by Vercel and the server function runs on Supabase. Both keep ordinary request logs, which may include your IP address for a short period as a normal part of running a web service.

Children

The game is suitable for a general audience and is not directed at children under 13, and we do not knowingly collect anything from them.

Removing your data

Clearing this site's data in your browser removes everything stored locally and detaches you from the random identifier. To have the rows tied to a specific identifier deleted from our server, email us with that identifier and we will remove them.
