Privacy Policy

Last updated: June 20, 2026

The short version

play20-0 is an independent, ad-free project. You can play completely as a guest, with everything kept on your own device. An account is optional. We store only the small amount of data described below, run no ads, and use no cross-site tracking.

Playing as a guest

Without an account, your progress — roster, season results, career stats, Hall of Fame, daily-challenge result and your duel history (records against friends) — is savedlocally in your browser (using localStorage). This stays on your device and is not sent to us. Clearing your browser data, or the "Reset all data" button on your profile, removes it.

If you create an account

Signing in is optional and uses a one-time email link (no password). If you sign in, we store, in our backend:

• Your email address — used only to sign you in and identify your account.
• A display name you choose — shown publicly next to your runs on the leaderboard.
• Your finished runs — record, result, difficulty, team and the drafted roster — so we can sync your career across devices and rank runs on the leaderboard.

We may add more sign-in options (such as Google) later; if we do, we will update this page.

Feedback

If you use the feedback form, we store the message you send so we can act on it. The form is anonymous — it doesn't ask for your name or email, so only include contact details if you want a reply.

Hosting & processors

We rely on third-party providers to host the site and store account data. Like any web host, they process standard technical request information (such as IP address and browser type) to serve the page and protect the service. These providers may process or store data on servers outside the EU. We only share what's needed to run the game.

Analytics & advertising

We run no advertising. We use Vercel Analytics for basic, privacy-friendly visitor statistics (such as page views and aggregate traffic). It is cookieless and collects no personal data— it doesn't track you across other sites or build a profile of you. We use no other third-party tracking.

Your control

You stay in control of your data. Guest data lives in your browser — clear it any time. If you have an account, the "Reset all data" button on your profile deletes your runs and display name from our backend and wipes your local progress. To delete your account entirely, including your sign-in email, email us at privacy@play20-0.comand we'll erase it.
