Privacy Policy

Last updated: 18 September 2026

Decision FC (“the game”, at decisionfc.com) is a free browser football-career game. This policy explains what data the game handles and how advertising works. It is written to be short and honest.

What the game stores

Your career progress, chosen settings, and language preference are stored locally in your own browser (via localStorage). There is no account and no login, and this information never leaves your device except as described below. Clearing your browser storage erases it.

The leaderboard

If a finished career is submitted to a public ranking, only gameplay data is sent — the random seed, the list of decisions you took, and the display name you typed for your player. This is used to re-simulate the career for anti-cheat and to place it on the board. Please do not type real personal information as a player name.

Counting how the game is played

The game keeps a small daily tally of seven things: a page being opened, a career being started, a player being created, a career reaching its fifth season, a career being finished, a replay being started, and a result being shared. It also counts crashes.

A tally is all it is. Each of those is one number per day for the whole site — "this many careers were finished on the 14th" — and nothing is sent with it. There is no visitor or session identifier, no cookie, no stored id, no device or browser details, no page path, and nothing about your career. Two events from the same person cannot be linked to each other, and no number in the tally can be traced back to anybody, including by us. It exists to answer one question we could not otherwise answer: how many people start a career and never finish one.

One thing does touch your address, and it is about abuse rather than measurement. As with every request to every website, yours reaches the server carrying your IP address. Neither the tally nor the leaderboard stores it. What the server does instead is hash that address together with a secret key it generated itself, and keep the hash — with a count, and nothing else beside it — for five minutes, so that a single caller cannot flood the counters or the leaderboard. It is deleted once the five minutes are up, it is never joined to a tally row or a leaderboard entry, and your address itself is never written down.

If your browser sends Global Privacy Control or Do Not Track, nothing is sent at all.

Advertising and cookies

The game is free and supported by rewarded video ads, served through Google AdSense. Google and its partners use cookies and similar identifiers to serve and measure ads, and — with consent — to personalise them. You can read how Google uses this data at policies.google.com/technologies/partner-sites, and manage your ad personalisation at adssettings.google.com.

If you are in the European Economic Area, the United Kingdom, or Switzerland, a consent prompt (a Google-certified consent management platform) asks your permission before any personalised advertising cookies are used, and you can decline or choose non-personalised ads. You can change your choice at any time through that prompt or your browser settings.

Who else is involved

Google AdSense — advertising.
Cloudflare — hosting and content delivery for the site.
Supabase — stores the leaderboard submissions and the daily counters described above.

These providers process only what is needed for their function.

Children

The game is not directed at children under 13 (or the minimum age in your country), and it does not knowingly collect personal information from them.

Your rights

You can erase all locally stored data by clearing your browser storage. If you are in a region with data-protection rights (such as the EEA or UK), you may withdraw advertising consent through the prompt above, and you may contact us about any data question.

隐私政策

最后更新：2026 年 9 月 18 日

足球生涯 Decision FC（本游戏，网址 decisionfc.com）是一款免费的网页足球生涯游戏。本政策说明游戏会处理哪些数据、广告是怎么运作的，尽量写得简短、诚实。

游戏会存什么

你的生涯进度、设置和语言偏好都只存在你自己浏览器本地（通过 localStorage）。游戏没有账号、不用登录，这些信息除下文说明的情况外不会离开你的设备。清除浏览器存储即可删除。

排行榜

如果你把一段完成的生涯提交到公开排名，只会上传游戏内数据——随机种子、你做过的选择列表，以及你为球员输入的显示名。这些用于服务器端重演该生涯做反作弊校验并计入排行榜。请不要用真实个人信息作为球员名字。

关于游戏被怎么玩的计数

游戏会按天记七件事的总数：打开页面、开始一段生涯、创建球员、生涯打到第五个赛季、生涯完成、开始重玩、分享战绩。另外还会记崩溃次数。

它就只是个计数。每一项都是全站每天一个数字——比如"14 号这天有多少段生涯完成了"——除此之外什么都不会上传：没有访客或会话标识，没有 Cookie，没有存下来的 id，没有设备或浏览器信息，没有页面路径，也没有任何生涯内容。同一个人的两次事件之间无法关联，这份计数里的任何数字都追溯不到任何人，我们自己也一样。它的存在只为回答一个否则无法回答的问题：有多少人开了一段生涯却从来没打完过。

只有一处会碰到你的地址，而它是为了防滥用，不是为了统计。和你访问任何网站一样，你的请求到达服务器时会带着你的 IP 地址。计数不会存它，排行榜也不会。服务器做的是把这个地址和一把它自己生成的密钥一起做单向哈希，只保留这个哈希值和一个次数，保留五分钟，用来防止同一个来源刷计数或者刷排行榜。五分钟后即删除，它永远不会和某条计数或某条排行榜记录关联起来，你的地址本身也从来不会被写下来。

如果你的浏览器发送 Global Privacy Control 或 Do Not Track 信号，那么什么都不会上传。

广告与 Cookie

本游戏免费，靠激励视频广告支持，通过 Google AdSense 投放。Google 及其合作伙伴会使用 Cookie 和类似标识来投放、衡量广告，并在获得同意后用于个性化广告。你可以在 policies.google.com/technologies/partner-sites 了解 Google 如何使用这些数据，并在 adssettings.google.com 管理你的广告个性化设置。

如果你在欧洲经济区、英国或瑞士，在使用任何个性化广告 Cookie 之前，会先出现一个同意提示（由 Google 认证的同意管理平台提供），你可以拒绝或选择非个性化广告，并可随时通过该提示或浏览器设置更改选择。

还涉及谁

Google AdSense——广告。
Cloudflare——网站托管与内容分发。
Supabase——存储上文所述的排行榜提交数据与每日计数。

这些服务商只处理其功能所必需的数据。

儿童

本游戏不面向 13 岁（或你所在国家的最低年龄）以下的儿童，也不会有意收集他们的个人信息。

你的权利

清除浏览器存储即可删除所有本地数据。如果你所在地区有数据保护权利（例如欧盟或英国），你可以通过上面的提示撤回广告同意，也可以就任何数据问题联系我们。
