Privacy Policy

50-0 is an independent, fan-made boxing game. This page explains what information the game collects when you play, why it's collected, and what choices you have about it.

What we collect

If you never create an account: nothing is sent to us. Your sound and colourblind-mode preferences are stored only on your own device, using your browser's local storage, and never leave it.

If you create an account, either with an email and password or by signing in with Google, we collect and store:

• Your email address, used only to let you sign in and to send account-related emails (like confirming your address).
• A display name you choose, which is shown publicly wherever your results appear.
• Your gameplay results: PvP win/loss record and rating, your best Sprint and Career Mode runs, your Trivia Cup record, and any fighters you retire in Career Mode (Hall of Fame).

If you sign in with Google, Google shares your email address with us as part of that process, governed by Google's own privacy policy in addition to this one.

How we use it

• To let you sign in and keep your account secure.
• To run PvP matches and calculate ratings.
• To display leaderboards and Hall of Fame entries.
• To send you account-related emails (like email confirmation). We don't send marketing emails.

Who else sees it

We use a small number of third-party services to run the game. We don't sell your data to anyone.

• Supabase hosts our database and handles sign-in. Your account data is stored on their infrastructure under their own security and privacy practices.
• Google, only if you choose to sign in with Google, in which case standard OAuth sign-in data is exchanged as described above.
• Netlify hosts the website itself, and may log standard technical information (like IP addresses) as part of normal web hosting, the same as almost any website you visit.

Cookies and local storage

The game uses your browser's local storage to keep you signed in between visits and to remember preferences like sound and colourblind mode — none of that is sent to us.

We also use Google Analytics to understand how people play — which pages and modes get used, and roughly how much traffic the site gets. This sets a cookie and shares some data with Google, governed by Google's own privacy policy in addition to this one. It only runs if you click "Accept" on the cookie banner shown on your first visit — declining means it never loads at all, and you can change your mind at any time from the cookie preferences link in the app. We don't use advertising cookies, and we don't sell or share your data with advertisers.

How long we keep it

We keep your account and gameplay data for as long as your account exists. If you'd like your account and data deleted, contact us using the details below and we'll remove it.

Your rights

Depending on where you live, you may have the right to:

• Ask what data we hold about you.
• Ask us to correct inaccurate data.
• Ask us to delete your account and data.
• Withdraw consent at any time by deleting your account.

If you're in the UK or EU, you also have the right to complain to your local data protection authority (in the UK, this is the Information Commissioner's Office) if you're unhappy with how we've handled your data.

Children's privacy

50-0 is not directed at children, and we don't knowingly collect personal information from anyone under 13. If you believe a child has created an account, contact us and we'll remove it.

Changes to this policy

If this policy changes, we'll update the date at the top of this page. Significant changes — for example, if we start showing ads or collecting new types of data — will be reflected here before they take effect.
