Privacy Policy

Last updated: 11 November 2026

This explains what KillBounce collects, why, and what you can do about it. KillBounce is run by Mindful Games, an individual, in North Carolina, USA. Contact: support@killbounce.app.

What we collect

• Your account: your player name, email address, and password. The password is stored only as a secure one-way hash, so we can't read it.
• Your game: the colors and items you own and wear, saved paddle designs, points and level, and your match history: who you played, the scores, and when.
• Purchases: what you bought, when, the price, and Stripe's payment reference. Stripe handles the payment itself, and we never see your card details. Stripe's own privacy policy covers what it collects: stripe.com/privacy.
• Technical information: to keep the game running smoothly, the server logs connections, disconnections and their reasons, and short performance reports from your game. These include the kind of device and browser you use. Server logs are kept for about 14 days. The server also measures each connection's ping (round-trip time) and keeps a short summary per match (average and worst ping, dropped connections, slow frames).
• Reports and messages you send: if you report a player, we keep the report (who reported whom, the reason, your note) and a picture the server draws of both players' names and paddles. If you send a bug report or a CONTACT US message, we get what you wrote, your player name and email (or the email a guest gives us), and, for bug reports, details about your device, connection and your last few matches.

Guests (playing without an account) give us no personal information.

What we use it for

• To run your account and the game: signing in, matchmaking, stats, leaderboards and the shop.
• To email you sign-up and password-reset codes. We don't send marketing email.
• To find and fix bugs and lag.
• To review player reports and keep the game friendly: a player who breaks the rules can be banned, which closes their account and stops their name and email address being used for a new one.
• To answer your messages and bug reports.
• To keep records of purchases, as the law requires for tax and accounting.

We don't sell your information, and we don't use advertising or tracking cookies.

What other players see

Your player name, level, online status, wins and losses, and recent match results are visible to other players. Your email address never is.

Who else handles it

• Hetzner hosts our server in the United States.
• Cloudflare runs our domain and sends our emails.
• Stripe sells our items as merchant of record: it takes the payment, handles sales tax and VAT, and sends receipts. To do that it gets your email address and payment details directly from you at checkout.

They handle the information only to provide those services to us.

On your device

The game saves a sign-in token, so you stay signed in, and a short "seat ticket" that puts you back in your match if your connection drops. In the browser, these are kept in the browser's local storage. They aren't used for tracking. Signing out removes the sign-in token.

Keeping and deleting

You can delete your account in the game: MY STATS, then DELETE ACCOUNT. This permanently removes your email address, password, sign-ins and saved designs, and your name is removed from your profile and from match histories. Purchase records (the player name at the time of purchase, item, price, date and payment reference) are kept, because the law requires them for tax and accounting. They are stored in a tamper-proof record that can't be edited. You can also email us to ask what we hold about you, to correct it, or to delete it.

Children

KillBounce isn't meant for children under 13, and we don't knowingly collect their information. If you think a child under 13 has made an account, email us and we'll delete it.

Security

Connections to KillBounce are encrypted (HTTPS), passwords are hashed, and the server is only reachable through its game and web ports.

Changes

If this policy changes, we'll update the date at the top, and tell players in the game about important changes.
