UltiMax is a free game by Max Coe. It is made to collect as little about you as possible. This page explains what it stores and why.
Playing as a guest
Your team, progress and settings are saved only in your own browser (its local storage). Nothing about them is sent anywhere. Clearing your browser's site data deletes them.
The website itself remembers a few small things in your browser the same way, never sent anywhere: whether you closed the "Install the app" offer, and on the changelog your chosen view and the newest update you have seen (to mark what's new since your last visit).
Optional account
If you create an account, these are stored with Supabase, which runs the sign-in and cloud saves:
- your email address and password (the password is stored hashed by Supabase, never in readable form, and never by the game);
- your saved progress and settings, so you can play on other devices.
They are used only to sign you in and keep your save. They are never sold or shared for advertising. Only you can read or change your save; your email is visible only to the developer, to run the service.
Visitor statistics
The website counts visits with Vercel Web Analytics: anonymous page views, where visitors came from, and their country, device type and browser. It uses no cookies and does not identify you.
Fonts and hosting
The website is hosted by Vercel and loads its fonts from Google Fonts, so those services receive the usual technical details of your visit (such as your IP address) when your browser asks for the page.
Children
The game is for a general audience and needs no account. Please don't create an account if you are under 13.
Deleting your account
Signed in, open ACCOUNT and press DELETE ACCOUNT: after you confirm with your password, your account, cloud save, team name and friends list are deleted right away. If you can't sign in, contact the developer through the game's GitHub page. Guest saves can be deleted by clearing your browser's data for this site.
