Terms of Use and Licence Agreement

Last updated: 10 November 2026

These terms are an agreement between you and mhugo LLC, a Georgia limited liability company doing business as J|K|L ("J|K|L", "we", "us"). They cover jkltools.com and every J|K|L app, free or paid. By downloading, installing or using a J|K|L app, or buying a licence, you agree to them. If you're agreeing for a company, you confirm you can bind it, and "you" means the company.

1. Who you buy from

When we sell an app, it's sold through Lemon Squeezy, our merchant of record. Lemon Squeezy takes your payment, charges any sales tax or VAT, sends your receipt and licence key, and handles refunds. Your purchase is also covered by Lemon Squeezy's Buyer Terms. The software itself is licensed to you by J|K|L under these terms.

2. The licence

We license our apps to you; we don't sell them. Subject to these terms, we give you a non-exclusive, non-transferable licence to use each app under the licence you have. Paid licences apply once an app is on sale:

  • Full licence. One person may use the version they bought (for example, Line|Cut 1) on up to two Macs they own or control, for as long as they like. It doesn't expire and isn't a subscription.
  • Project licence. One person may use the app on one Mac for 30 days from activation, for a single project. When the 30 days end, the app stops working until you buy another project licence or a full licence.
  • Free trial. Where an app offers a free trial, anyone may use it for 30 days to evaluate the app. A trial is limited as described on the app's page (Line|Cut's writes the first minute of results). Don't use a trial to deliver work.
  • Free apps. Some apps, such as Bin|Set, are free. You may use a free app on any Mac you own or control, for as long as we offer it. Get it from jkltools.com; don't resell or redistribute it. Section 4 and the refund policy don't apply to free apps.
  • Betas. If we invite you to test a pre-release version, you may use it until it expires or the app is released. A beta may have more bugs than a release and may stop working when the beta ends, so keep your own copies of important work and check its results before you deliver them. Sections 10 and 11 apply to betas in full.
  • Education licence. Sold at a reduced price to students and teaching staff of accredited schools. We may ask for proof of eligibility.

You may move a full licence to a different Mac by releasing one of your two Macs, from the app or by writing to hello@jkltools.com.

3. Updates and upgrades

  • A full licence includes every update to the version you bought (every 1.x update for Line|Cut 1), free, with no time limit.
  • If the next major version (for example, Line|Cut 2) comes out within 12 months of your purchase, it's included.
  • After that, owners can upgrade to the next major version at the owner upgrade price shown on our site. Your current version keeps working whether or not you upgrade.

We're not obliged to release updates or new versions, or to keep supporting older versions or older macOS releases.

4. Project licence credit

If you buy a full licence of the same app version within 90 days after a project licence ends, the project licence's price comes off. Several project licences add up, but the credit can't exceed the full licence's price and only applies to a full licence.

5. Activation and the licence check

A licence key unlocks the app. Unlocking needs an internet connection once. After that, the app checks the licence quietly whenever your Mac is online, and keeps working offline with no time limit. We may switch off a licence, and the app will stop working, if the purchase was refunded or charged back, the key was obtained fraudulently or shared beyond these terms, or you released that Mac. The privacy policy says what the check sends.

6. What you may not do

You may not:

  • share, sell, rent, lend or publish your licence key, or use one licence on more Macs than it covers;
  • transfer your licence to someone else without our written consent;
  • copy, modify or distribute the app, except as these terms or an open-source licence (section 8) allow;
  • reverse engineer, decompile or disassemble the app, except where the law allows it despite this limit;
  • remove, bypass or interfere with the licence check, trial limits, or any notice in the app;
  • use the app in breach of the law, including export laws.

7. Your files and your ideas

Your media, sequences, projects and the files our apps write are yours. Our apps work on your Mac; we don't receive or claim any right in your files.

If you send us feedback, suggestions or ideas for apps, we may use them to improve or make our apps, without owing you anything for them. Please don't send anything confidential.

8. Open-source components

Our apps include open-source software, each under its own licence (for example, Python under the PSF Licence, and FFmpeg under the LGPL or, in some apps, the GPL). Those licences, not these terms, govern those components, and nothing here limits your rights under them. Each app lists its components and licences in its Acknowledgements. Where a licence such as the LGPL or GPL entitles you to the source code or to replace the library, write to hello@jkltools.com.

9. Other companies' products

Our apps work with software made by others, such as Avid Media Composer. Those products and their names belong to their owners. J|K|L isn't affiliated with or endorsed by them, and changes they make may affect how our apps work with them.

10. No warranty

Our apps are provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We don't promise that an app will be error-free, will find every edit, or will work with every file, codec, frame rate or version of other software.

Check the results before you rely on them. Our apps help with editorial work; they don't replace your review. You're responsible for checking any sequence, list or file an app produces before it's delivered, aired or published.

11. Limits of liability

To the fullest extent the law allows, J|K|L won't be liable for any indirect, incidental, special or consequential damages, or for lost profits, lost data, lost work, missed deadlines or delivery errors, even if we were told they were possible. Our total liability for any claim about an app or these terms is limited to the amount you paid for that app's licence in the 12 months before the claim, or US$50 if that is more.

12. Ending the licence

Your licence ends automatically if you break these terms, and we may switch off your key. When it ends, stop using the app and delete it. Sections 7 to 14 continue after it ends.

13. Your rights where you live

Some places don't allow certain warranty disclaimers or liability limits, or give consumers rights that a contract can't remove. Where that's the case, those rights apply and these terms apply only as far as the law allows.

14. The law and changes

These terms are governed by the laws of the State of Georgia, USA, without regard to its conflict-of-laws rules, and any dispute will be heard in the state or federal courts located in Fulton County, Georgia, except where the law where you live gives you the right to bring a claim locally. If any part is found unenforceable, the rest still applies. We may update these terms; the date above shows when they last changed, and the terms in force when you bought a licence keep applying to that licence unless you agree otherwise.
