Terms of use

Last updated: 9 November 2026

These terms are an agreement between you and Shitan Yang (“we”, “us”) about the Greenkeeper app and this website. They include the license agreement for the app. By downloading, installing or using Greenkeeper, you agree to them. If you don’t agree, please don’t use Greenkeeper.

1. Your license

Greenkeeper is licensed, not sold. As long as you follow these terms, we give you a personal, non-exclusive, non-transferable license to install and use Greenkeeper on Macs you own or control.

• Free features. You may use Keep Awake, the free part of Greenkeeper, without a license key and with no time limit.
• Pro. A Pro license is for one person and can be activated on up to 3 Macs that person uses. Each person who uses Pro needs their own license.
• License keys. Keep your license key to yourself. Don’t share, publish or resell it.

2. What you may not do

You may not:

• sell, rent, lend, sublicense or redistribute Greenkeeper or its license keys;
• bypass or disable the license check or the trial limit;
• copy, modify, reverse engineer, decompile or disassemble the app, except where the law allows it despite this restriction; or
• remove copyright, trademark or other notices from the app.

3. Free trial

Greenkeeper includes a free 7-day trial of the Pro features. It starts the first time you open the app and needs no account or payment details. When the trial ends, the Pro features stop until you activate a license. Keep Awake keeps working.

4. Buying Pro

Pro is a one-time purchase, priced in US dollars on our website. Our payment provider sells Greenkeeper as our reseller and merchant of record: it processes your payment, charges any sales tax or VAT that applies, issues your receipt and emails your license key. Its terms of sale, which you’ll see at checkout, also apply to your purchase.

5. Refunds

If Pro isn’t right for you, you can get a refund within 14 days of purchase. Ask by replying to your receipt or by emailing support@getgreenkeeper.com. The merchant of record issues the refund to your original payment method, and the license key is deactivated. This doesn’t limit any rights you have under consumer law.

6. Updates and support

We may release updates that fix problems or change, add or remove features. We’re happy to help by email at support@getgreenkeeper.com, but these terms don’t guarantee updates or support.

7. Acceptable use

You’re responsible for how you use Greenkeeper. You agree to:

• comply with the laws that apply to you;
• follow the policies of your employer, your clients and anyone else whose devices, accounts or systems you use, including rules about what software you may install and how you report your time and availability; and
• not use Greenkeeper to misrepresent billable time or hours worked, or to deceive or defraud anyone.

Some organizations don’t allow tools like Greenkeeper, and employee-monitoring software can detect them. If you’re not sure, ask before you use it on a work Mac.

8. Other companies’ apps

Greenkeeper works alongside apps we don’t control, such as Slack and Microsoft Teams. Those apps can change how they decide whether you’re active at any time, and we can’t guarantee that Greenkeeper will work with any particular app or version. Browser-based versions of chat apps aren’t affected by Greenkeeper.

Slack is a trademark of Slack Technologies, LLC. Microsoft and Microsoft Teams are trademarks of Microsoft Corporation. Greenkeeper is not affiliated with or endorsed by either.

9. Privacy

Our privacy policy explains what data Greenkeeper and this website handle.

10. No warranty

Greenkeeper is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We don’t promise that Greenkeeper will be error-free, work with every app or setup, keep your status active in every situation, or go unnoticed by device-management or monitoring software.

11. Limitation of liability

To the fullest extent the law allows, we won’t be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, data, goodwill, employment or business opportunities, arising out of or related to Greenkeeper, even if we were told such damages were possible.

Our total liability for any claim relating to Greenkeeper is limited to the amount you paid for it in the 12 months before the claim, or US$10 if you paid nothing.

Some places don’t allow these exclusions or limits, so they may not fully apply to you. Nothing in these terms limits liability that can’t be limited by law, such as liability for fraud, or for death or personal injury caused by negligence.

12. Ending this agreement

You can stop using Greenkeeper at any time by deleting it. If you seriously or repeatedly break these terms, for example by sharing license keys or using Greenkeeper to defraud someone, we may end your license and deactivate your key, giving you notice where practical. When your license ends, you must stop using Greenkeeper and delete it. Sections 2, 7, 10, 11, 14 and 15 continue to apply after this agreement ends.

13. Changes to these terms

We may update these terms from time to time. We’ll post the new version on this page and update the date at the top. Changes apply from that date and don’t reduce your rights for purchases made before it. If you keep using Greenkeeper after a change, the updated terms apply.

14. Governing law

These terms are governed by the laws of the State of California, United States, without regard to its conflict-of-law rules. The state and federal courts located in California will handle any dispute. If you’re a consumer, you keep the protection of the mandatory laws of the country where you live, and you may be able to bring a claim in your local courts.

15. General

If any part of these terms can’t be enforced, the rest still applies. If we don’t enforce a term straight away, we can still enforce it later. You may not transfer these terms or your license to someone else; we may transfer them to a company that takes over Greenkeeper. These terms and our privacy policy are the whole agreement between you and us about Greenkeeper.
