Terms and refunds

Effective date: December 1, 2026

These terms are between you and Great Desktop Apps, LLC, who make Overworld. They cover the Overworld app for Android and the licenses sold for it. By buying a license or using Overworld, you agree to them.

The short version

Overworld is a free download. A license is a one-time purchase that unlocks games and includes 12 months of profile updates. It never expires. If Overworld doesn't work out for you, ask for a refund within 7 days of buying.

The app

Overworld is free to download and use, and vanilla Emerald works without a license. You need an Android device and a RetroArch setup that meet the requirements on the Overworld page (today that means a RetroArch nightly build with Network Commands turned on), and your own copy of each game. Overworld includes no games or ROMs. It reads the game you're already playing and never changes your game or your saves.

Overworld is an independent tool. It isn't affiliated with or endorsed by RetroArch or by the authors of any ROM hack.

Licenses

• What you get. A license unlocks the games you bought, and the bundle license unlocks every supported game. It comes as a small file you open on your device. Your license is never checked online.
• One payment, no subscription. Each license includes 12 months of updates from the day you buy: new and updated game profiles, such as support for new hack releases, and the Overworld versions that carry them. Your license doesn't expire. It keeps unlocking your games in every Overworld version released during those 12 months. After that you can renew for another 12 months if you want to, but you never have to.
• It's yours, not for sharing. A license is for your own personal use, on devices you use. Please don't share, publish or resell your license file. It also contains your email address, which is another reason to keep it to yourself.
• Lost it? Email us and we'll send you a replacement.

Buying

We grant the license, and Lemon Squeezy sells it on our behalf as the merchant of record. Lemon Squeezy takes your payment, handles tax and issues your receipt, and its own buyer terms apply to the payment. Your license file reaches you by email after you buy.

Refunds

If Overworld doesn't work for you, ask for a refund within 7 days of buying and you'll get your money back in full. A renewal can be refunded within 7 days of the renewal payment. Reply to your license email or write to support@greatdesktopapps.com from your order email, and we'll refund you through Lemon Squeezy.

A refund ends your right to use that license. The license file works offline, so we can't switch it off remotely, and we ask you to delete it from your devices. After 7 days, purchases aren't refundable, except where the law where you live says otherwise.

Updates and support

We work to keep Overworld accurate and working with the games it supports, and we answer support email. Games, emulators and devices change outside our control, though, so we can't promise that every future version of a game, RetroArch or Android will work.

No warranty

Overworld is provided as it is. To the extent the law allows, we make no promises beyond those in these terms, and our total liability to you is limited to what you paid us for your license. Nothing here limits rights you have under consumer law that can't be limited.

Changes

If these terms change, we'll update the date at the top. Changes don't affect a license you've already bought, including the refund window that applied when you bought it.
