Terms of Use and License
Lightspill · Last updated October 5, 2026
These terms cover your use of Lightspill ("the app"), made by GDW Entertainment ("we"). By installing or using the app you agree to them.
Free use and the trial
Keeping your Mac awake with Lightspill is free to use. "Keep running with lid closed" (lid mode) is free for 7 days, starting the first time you turn it on. After that it needs a license.
Your license
- A license is a one-time purchase that unlocks lid mode in the current version of Lightspill and its updates.
- You may use one license on up to three Macs that you own or control. Removing it from one Mac (in the app) frees that activation for another.
- Licenses are for you, not for resale or sharing publicly. We may disable a key that has been published or used to defraud.
- The app is licensed to you, not sold. You may not reverse engineer it to get around licensing, or redistribute modified copies.
Payments and refunds
Purchases are made through Lemon Squeezy, our reseller and merchant of record, whose buyer terms also apply. If Lightspill isn't right for you, email us within 14 days of purchase for a full refund, no questions asked. A refunded license key is disabled.
Using lid mode safely
A Mac running with its lid closed still makes heat and uses battery. Lightspill stops lid mode at the battery level you choose and when macOS reports the Mac is critically hot, but you are responsible for where you leave a running Mac. Don't run long jobs in a closed bag or on soft surfaces that block airflow.
No warranty
Lightspill is provided "as is", without warranty of any kind. We work to keep it reliable, including always restoring your Mac's normal sleep setting, but we do not guarantee it is free of errors or suitable for any particular purpose.
Limitation of liability
To the extent the law allows, GDW Entertainment is not liable for any indirect, incidental or consequential damages, including lost data, battery wear or hardware damage, arising from your use of the app. Our total liability is limited to the amount you paid for your license.
Changes
We may update these terms; the date above will change. Continuing to use the app after a change means you accept the new terms.
