Terms of service

1. The agreement

By downloading or using Lumen ("the app"), you agree to these terms. The app is published by Lumen Software ("we", "us"). If you don't agree, don't use the app.

2. License to use the app

We grant you a personal, worldwide, non-transferable license to install and run the app. The free tier permits up to three projects on a single Mac. A Pro license permits unlimited projects across up to three devices that you own or control.

You may not redistribute the app, sell access to it, or remove its copyright notices. You may not reverse engineer the app except where that right is granted by law.

3. Your content stays yours

Lumen edits files that live on your computer. We do not claim any ownership of your content, your code, or your projects. We do not host them. We do not see them.

4. Pro purchases

A Pro license is a yearly subscription. The first year is billed at the introductory rate; subsequent years renew at the standard rate listed on the pricing page at the time of renewal. You can cancel renewal at any time from your license page; the app remains licensed through the end of the period you paid for.

If something goes wrong with your purchase within 14 days (buyer's remorse, didn't realize what it was, anything), email us and we'll refund you.

5. Updates and changes

Lumen is a young product. We will ship updates that change behavior, add features, and occasionally remove features that aren't working. We'll do our best not to break your projects, but we cannot promise that every version will be backward compatible with every workflow.

6. Warranties

The app is provided "as is". We make no warranty that it will be uninterrupted, error-free, or fit for any particular purpose. Always keep backups of your work, ideally in version control, which Lumen is designed around.

7. Limitation of liability

To the maximum extent allowed by law, our total liability to you under these terms is capped at the amount you paid us in the previous 12 months (which is $0 if you're on the free tier).

8. Changes to these terms

We may update these terms when the product changes meaningfully. If we do, we'll update the date at the top of this page. Continued use of the app after a change counts as acceptance.
