Need several apps or a build without the watermark? Talk to us.

Licensing, answered.

Is AI integration included?

Yes, on every plan. Every build includes the runtime that lets an AI model read and edit the chart, and the SDK is open source under the Apache License 2.0.

Does the chart need a licence key or an internet connection?

No. Lumen Charts never contacts us, needs no key and works fully offline. Your licence is a contract, and your account gives you the build your plan includes.

What counts as one app?

One product under one base domain, including all its subdomains and any number of pages, users and charts. localhost always works. A separate product needs its own licence, or talk to us about Enterprise.

Can I try it before buying?

Yes. Create an account and download the Evaluation build. It includes the same features as Indie and Business, with an "Evaluation" watermark for development and testing. No card needed.

Do I get the source code?

Indie and Business include the production build of the chart: minified JavaScript with full TypeScript definitions, which is everything you need to integrate and ship. The Evaluation build comes in the same format, so you can see exactly what you get before you buy. Source code is not part of these plans. If you need it, tell us what for and we can discuss it as part of an Enterprise agreement. The AI integration SDK and the trading platform are open source under the Apache License 2.0.

What happens if I cancel or a payment fails?

If you cancel, paid downloads stop at the end of your paid period. You can keep your existing production deployment running for 30 days after that. If a renewal payment fails, you have up to 14 days of grace while we retry.

Who can use Indie?

Individuals, and companies whose annual revenue and total funding raised are each under $100,000. You confirm this at checkout. If your organisation passes either amount, move the app to Business at its next renewal. You can upgrade from your account at any time, and Stripe charges the prorated difference straight away.

Can I move from Business to Indie?

Yes, if your organisation meets the Indie limits. Email support@lumencharts.com and we'll switch the app at its next renewal.

How do I remove the watermark?

Indie and Business builds carry a small Lumen Charts watermark. A build without it comes with Enterprise, which we arrange with you: tell us about your product on the Enterprise page.

Do you send invoices with company details?

Yes. Add your company name, address and tax ID at checkout and they appear on every invoice, which you can download from your account.
