Sumex is a small game studio that makes games on Roblox. This page explains, in plain words, what data we see and what we do with it.

This website (sumex.games)

There are no accounts, no ads, no tracking cookies and no analytics scripts.
Player counts and similar numbers are loaded from Roblox's public game data.
The site is hosted on Cloudflare, which may keep standard technical logs (such as IP address and browser type) to keep the site running and secure.

Sumex Studio is a private tool for the Sumex team. It uses "Log in with Roblox".

When you log in, Roblox shares your Roblox user ID and username with us. We ask for nothing else.
We use them only to check whether your account is allowed in. If it is, they are kept in a signed login cookie on your device for up to 30 days. They are not saved in a database or shared with anyone.
If your account isn't allowed in, nothing is kept.
While you log in, a second cookie keeps the login safe for up to 10 minutes and is then deleted.
Logging out removes the cookie. You can also remove Sumex Studio's access at any time in your Roblox account settings.

Our games run on Roblox, so your Roblox account and purchases are handled by Roblox under the Roblox Privacy Policy.
Games save your progress (for example coins and upgrades) linked to your Roblox user ID, so it is there next time you play.
We use gameplay analytics (such as play time, where players get stuck, and error reports) to fix bugs and improve the games. These are linked to Roblox user IDs, not to real names or contact details, and we don't sell them.

Message us on Discord or X. If we change this policy, we'll update the date at the top.
