You can play without an account. The site saves game progress in your browser, verifies optional Daily results on the server and loads Google Analytics only after consent.
What stays in your browser?
Game progress, local results, Survivor streaks, display-name preference, motion preference, analytics choice and a random browser ID use localStorage. They stay until you clear site storage or the relevant saved preference expires. Clearing storage also resets that browser identity.
What does the leaderboard store?
The Cloudflare D1 database stores the random browser ID, UTC day, session, action log and server-replayed result. Submitted display names, wins, margins and play counts are public on the Daily board. A real name or email is not required. These entries remain until removed by the operator.
What happens when you contact the operator?
The Contact page provides a mail link to lanmeiop@163.com. Sending an email shares your email address and chosen message with the operator and the email providers involved in delivery. Email correspondence is used to address the request and kept until it is no longer needed or is removed. The website does not upload the email's contents or add them to analytics events.
How does optional analytics work?
Google Analytics 4 loads after you choose Allow analytics. It measures page views, game starts, calls, mode changes and results. Advertising storage, Google Signals and advertising personalization are disabled. Page addresses and referrers omit query strings and fragments. Your choice and the configured analytics-cookie lifetime are 180 days.
Rejecting analytics does not affect gameplay. Withdrawing consent disables future analytics collection and clears accessible analytics cookies; it cannot undo data previously processed by Google. See Google's privacy policy.
Which providers deliver the site?
Cloudflare hosts the website, database and operational request logs. Typeface files are bundled with the site and served by Cloudflare. These providers receive normal request information such as your IP address when their services are requested. Optional Google Analytics processes visit information only after consent. See Cloudflare's privacy policy.
