Privacy
Last updated 7 November 2026The short version
Accounts are optional. If you never make one, we store no account data about you and your progress stays on your device. (The games still go online to check for updates and for online play, described below.) If you choose to make one, we store a small amount of data (listed below) so you can sign in on other devices. This website shows ads from Google AdSense, which uses cookies. The games you download, and the Android app, have no ads and no analytics. The games only contact the internet to check for updates, for online play, and for your account if you make one.
Accounts (optional)
You can play without an account. If you create one, we store:
- your username;
- your email address, only if you choose to add one;
- your save data (progress, best times and ratings) and your friends list;
- the time you were last online.
Part of this is a public profile that other players can see: your username, friend code, VR and Power ratings, the fighter you play most (if the game shares it) and when you were last online. Your email, password, save details and friends list are never public.
This data is kept with Google Firebase (Authentication and Firestore). Sign-in requests pass through a small server we run on Cloudflare, which may process your IP address to limit abuse. Your password passes through our login helper to Firebase to be checked. We never store it, and Firebase keeps only a scrambled (hashed) version. If you get a recovery code, we store only a scrambled (hashed) version of it, never the code itself.
If you add an email, it is used only to reset your password. We do not send marketing, and we do not sell or share it.
To delete your account, open Account in the game and choose Delete my account, or use the account deletion page if you can no longer open the game. This permanently removes all your account data: your login, email, username, save, friends list, recovery code and online profile. It can't be undone.
Game saves
Without an account, Pixel Smash and Pixel Smash Kart keep your progress, settings, username, friend code and friends list in your browser's local storage, on your device. It is not sent to us. Clearing your browser data deletes it, so copy a save code first if you want to keep it.
Online play and friends
Online and LAN play connect your device directly to other players (WebRTC). To find each other, the games use the public PeerJS matchmaking server. That server, and the players you connect to, can see your IP address, as with any online game. Your username, friend code, fighter or racer and rating are shared with the players you meet. If you play as a guest, we don't receive or store any of it. If you have an account, your username, friend code, rating and friends list are stored with your account (see Accounts above).
