Terms & licence

Terms of sale and software licence

Last updated 15 October 2026

1. Who you're dealing with

Lid Keeper (the "Software") is developed and sold by JTTTSOLUTIONS INC — legally JTTTsolutions, Inc., a Delaware corporation ("we", "us"). These terms apply to your purchase from lidkeeper.com and to your use of the Software. By buying or installing the Software you agree to them.

2. What you get

On payment we grant you a personal, non-exclusive, non-transferable licence to install and use the Software on one computer (a Mac or a Windows PC) at a time, owned or controlled by you, for your own use. The licence is delivered as a licence key on the order page and by email. Keep it; it is your proof of purchase.

Who owns the licence. The person the key is delivered to owns it: you, if you bought it for yourself; the named recipient, if you bought it as a gift. A gift recipient owns their licence outright, including the right to move it, whether or not they paid for it. Buying a gift does not give you continuing authority over it.

Moving to a replacement computer. You may move your licence to a different computer you own or control, a Mac or a Windows PC, as many times as you genuinely replace a machine, at no extra charge. You do this yourself from the new computer, verified by email to the address that owns the licence; you do not need access to the old one. Three moves in any rolling 30-day period are automatic; beyond that, contact support. When you move a licence you must stop using the Software on the previous computer and uninstall it.

Transferring your installation to a replacement computer is permitted. Selling, renting, sublicensing, publishing or otherwise sharing your licence key is not, and neither is reassigning an activated licence to a different person — that is not part of this offer. You may not redistribute the Software or circumvent its licence checks. You may not reverse-engineer or decompile the Software except to the extent the law expressly allows. All rights not granted here are reserved by us.

2a. Activation and internet access

An internet connection is required to activate the Software, to restore an activation that has gone missing on the same computer, and to move a licence. Once a computer is activated, ordinary use of the Software works offline: there is no expiry, no periodic check and nothing to renew, and an activated copy keeps working whether or not our service is reachable.

We run the activation service on ordinary commercial hosting and intend to keep it available, but we are a small company and we do not promise uninterrupted availability. While it is unavailable you can keep using an activated computer; you cannot activate a new one.

3. Price and payment

The Software costs the price shown at checkout, currently US$2.99, as a one-time payment. Payments are processed by Stripe. Taxes may be added at checkout depending on where you are. There is no subscription and no recurring charge.

4. Updates

Updates to the Software are free for the life of the product. We may add, change or remove features in updates; we will not remove the core keep-awake function from a version you have paid for. We are not obliged to keep supporting versions of macOS or Windows that Apple or Microsoft no longer supports.

5. Refunds

You may request a full refund within 30 days of purchase for any reason by emailing support@lidkeeper.com from the address used to buy. When a refund is issued your licence terminates, the key stops activating any further computers, and you must stop using and uninstall the Software. We have no way to delete an activation from a computer that is already activated and offline, so this is an obligation on you, not something we enforce remotely. See our refund policy.

6. Safety — please read this one

The Software keeps a MacBook awake with the lid closed, which is not a configuration Apple supports outside its documented closed-display setup. The Software is designed to return the Mac to normal sleep under thermal, battery and software fault conditions, and it never takes control of fan speed away from macOS. On Windows, the Software sets the lid-close action to Do nothing while it is on and restores your own setting when it stops; Windows laptops differ, and where a PC does not report its temperature to Windows the Software cannot watch the heat, so only the PC's own protection does. Even so, no software can make a laptop safe when its ventilation is blocked, when it is in a bag, on bedding or soft furnishings, in a hot environment, or when its hardware is damaged.

You are responsible for using the Software sensibly: keep the computer on a hard, ventilated surface while the lid is closed, and stop using it if the computer shows any sign of abnormal heat, swelling, smell or damage. You accept that you use the Software at your own risk.

7. Requirements

The Software requires a MacBook, MacBook Air or MacBook Pro running macOS 15 or later with working lid, power and thermal telemetry, and an administrator account for installation; Lid Keeper for Windows requires a laptop running 64-bit Windows 10 or 11. Some managed or unusual configurations may prevent installation or engagement; if the Software cannot verify its safety requirements it will refuse to engage, and you may request a refund under section 5.

8. No warranty

To the fullest extent permitted by law, the Software is provided "as is" and "as available", without warranties of any kind, express or implied, including any implied warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Software will be error-free or uninterrupted, or that it will work with every computer or every future version of macOS or Windows.

9. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits or hardware, arising out of or related to the Software or these terms, however caused. Our total liability for any claim relating to the Software or your purchase is limited to the amount you paid for it. Some jurisdictions do not allow certain exclusions or limitations; in those places our liability is limited to the smallest extent the law allows.

10. Third parties

Payments are handled by Stripe under its own terms. Apple, Mac, MacBook and macOS are trademarks of Apple Inc. Windows is a trademark of Microsoft Corporation. Lid Keeper is independent software and is not affiliated with, endorsed by or sponsored by Apple.

11. Termination

Your licence ends if you materially breach these terms, or on refund. On termination you must stop using and uninstall the Software. Sections 6, 8, 9 and 12 survive termination.

12. General

These terms are the whole agreement between you and us about the Software. If any part is found unenforceable, the rest remains in effect. Our failure to enforce a term is not a waiver of it. These terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-law rules, and nothing in them limits any rights you have as a consumer under the law of the place where you live.
