Terms

Draft terms for the MASHBOX preview, pending legal review. Last updated 2026-10-04.

Your account

You sign in with Google. One person per account.

Owning your games

MASHBOX works only with game files already on your PC. By using MASHBOX you declare that you own each game you mod, bought on Steam, and that its files on your PC came from that purchase. We never provide game files.

What MASHBOX does

MASHBOX installs our own code beside your game and changes how your copy plays on your PC. Uninstalling a mod restores your game folder. Back up anything you care about; MASHBOX backs up saves before a game's first modded launch.

Membership

Membership is a paid subscription through Stripe and can be cancelled at any time. It includes the mods for the games you own, early access to new mods, and requests and votes. A request is not a promise that we will build it.

Fair use

MASHBOX is for single-player games. Don't use it to cheat in online play, and don't redistribute our mods.

Publishers

If a game's publisher asks us to remove their game, we remove it within 24 hours.

No warranty

MASHBOX is provided as is. To the extent the law allows, we are not liable for indirect losses. These terms are governed by the laws of the British Virgin Islands.
