Your privacy on TerraForge

TerraForge is built to be simple and safe. Here's exactly what we do and don't do with your information.

What we keep

If you create an account, we store just two things: your email address and the usernameyou choose. That's it — no passwords (we sign you in with a one-time code), no date of birth, and no tracking of what you do.

What we never do

We never share or sell your email address, and we don't send marketing. We use your email only to send you a 6-digit sign-in code.

Ads and cookies

Some pages carry ads from Google AdSense, which help pay for hosting. Google sets cookies to serve and measure them, and we use Google Analytics to count page views. Neither ever receives your email address or anything you build.Ads here are always non-personalised. Because this site is made for anyone including children, we tell Google to treat it as child-directed, which turns off the interest-based targeting that would otherwise build a profile of whoever is looking. That earns us less. It is the right trade.If you are in the EU, UK or Switzerland we ask before loading either, and nothing loads until you say yes. Everywhere else you can decline at any time and we will stop.

Age

You must be 13 or older to create an account. You can still build, save, and share planets without one.

Planets you save

A planet is just a set of build settings — it contains no personal information. Public planets appear in the gallery and can be featured as Planet of the Week. Privateplanets aren't listed and are never featured, but anyone with the link can still open them.

Deleting your account

You can delete your account anytime from your account page. When you do, your private planets are deleted, your public planets stay in the gallery without your name, and your email and username are removed.
A binary star system's orrery: two suns close together, a red dashed dead-zone boundary, and a debris trail left by a destroyed world

New: Binary Star Systems 🌀

A system can now orbit two suns. Add a companion star when you build one — close, medium, or wide — and the physics decides what survives: a shared center of mass carves out a dead zone where gravity from both stars tears a world apart, leaving it as debris, and every surviving planet's orbit goes elliptical, moving fastest at closest approach and slowest out at aphelion. Push the separation to wide and the dead zone opens tens of AU across, wide enough to gut a system that would have been stable around one star alone. Stand on a world that made it through and you'll watch two suns cross the sky together.
