Is GN Math safe?

Short answer: yes. GN Math is a set of 171 browser games that run like any normal web page. You never download a file, install an extension or type in a password. Below is exactly what we do, and don't do, so you can judge for yourself.

What "safe" means here

• No downloads. Games load as HTML and JavaScript inside your browser tab. Close the tab and the game is gone.
• No accounts. There is no sign-up, no login and no chat, so there is nothing to leak and no strangers to talk to.
• No pop-ups or redirects. Clicking play starts the game. It never sends you to another site.
• No outside game servers. Every game file lives on this domain. Nothing is streamed from unknown hosts.

How a game gets onto the site

We only add games whose source code is public and released under an open license that allows sharing, such as MIT, BSD, GPL or Creative Commons. These are standard licenses approved by the Open Source Initiative or published by Creative Commons. Before a game goes live we read its license, check that its art and sound are also covered, and remove anything that calls out to another website, such as hosted fonts or tracking code. The original license file stays in the game folder.

Each game page names the author, links to the original code and says what, if anything, we changed. The full list is on the credits page. Open code means anyone can inspect what a game does, which is a stronger guarantee than a promise from us.

What is still up to you

A safe website does not override your school or workplace rules. If games are only allowed at lunch or after work, keep it to then. If a parent or teacher wants to review the site, every page explains the controls and content of its game in plain words.
