These terms cover how you use LumaBrowser, LumaByte's website, and the paid subscriptions we offer. We've kept them short and readable. If anything is unclear, email us and we'll explain in plain English.
By downloading LumaBrowser, creating a license, or using lumabyte.com, you agree to these Terms of Service and to our Privacy Policy. If you do not agree, do not use the software or the site.
If you are using LumaBrowser on behalf of a company or other organization, you are agreeing to these terms on that organization's behalf and you confirm you have authority to do so.
Lumabyte, LLC ("Lumabyte," "we," "us," or "our") builds and operates:
LumaBrowser is offered in three tiers:
Features, pricing, and tier boundaries may change. We'll post current pricing at /pricing.
When you purchase a paid subscription, we issue a license key through our partner Keygen.sh. You activate that key inside LumaBrowser; activation binds the key to a machine fingerprint.
You are responsible for:
If a key is compromised, email us (see Contact) and we will revoke and reissue it.
LumaBrowser is a general-purpose automation tool. You are responsible for how you use it. You agree not to:
We may suspend or revoke access to paid tiers if we reasonably believe these rules are being broken.
Paid subscriptions are processed through Stripe. We don't see or store your card details — Stripe handles payment data end-to-end. We receive your billing email, subscription status, and a customer reference from Stripe's webhook.
Subscriptions renew automatically at the end of each billing cycle (monthly or annual, depending on the plan you chose) at the then-current price for your tier. You can cancel at any time from the customer portal linked on /pricing. Cancellation takes effect at the end of your current paid period; your license remains active until then.
If we change prices, we'll give you at least 30 days' notice before the change applies to your next renewal. Existing annual subscriptions keep their price through the end of their current term.
Paid Pro and Enterprise subscriptions may be refunded in full if requested within 14 days of the initial purchase. After 14 days, subscriptions are non-refundable for the remainder of the current billing period; you can still cancel at any time from the billing portal to stop future renewals. To request a refund, email [email protected] from the address on your account.
Taxes, where applicable, are added to the listed price and handled by Stripe.
LumaBrowser is proprietary software. The application, the Lumabyte name, the LumaByte mark, the website design, and the documentation are owned by Lumabyte, LLC.
The LumaBrowser application ships with a PROPRIETARY SOFTWARE LICENSE (bundled with the installer). In plain English, that license grants you the right to run the software as intended by your tier, and prohibits:
Our open-source libraries (ResonantJs, OpenGridJs) are separate and are governed by their own permissive licenses — you'll find those terms in their respective repositories.
Your content stays yours. LumaBrowser runs locally. Templates, scripts, credentials, prompts, and browsing data live on your machine. We don't claim ownership of anything you create with the tool. The narrow exception is sanitized template data contributed by Community-tier users — see the Privacy Policy for exactly what that covers and how to avoid it.
You can stop using LumaBrowser at any time. Uninstall the app and cancel any active subscription from the billing portal.
We can terminate or suspend your license if you materially breach these terms (for example, the acceptable-use rules in Section 4) or if we are required to by law. Where practical we'll give you a chance to fix the problem before we act.
On termination: the license key stops activating, the software stops working on covered machines, and the sections of these terms that are meant to survive (IP, disclaimers, limitation of liability, governing law) continue to apply.
LumaBrowser and the website are provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied. To the maximum extent permitted by law, we disclaim all warranties of merchantability, fitness for a particular purpose, non-infringement, title, accuracy, and any warranties arising from course of dealing or usage of trade.
In particular:
LumaBrowser is an AI-assisted automation product. It uses large language models and generated code to produce selectors, templates, agent plans, extracted data, scripts, and chat responses. These outputs can be incorrect, incomplete, biased, stale, or entirely fabricated, and can change between runs.
You are solely responsible for reviewing AI-generated content before acting on it. Lumabyte, LLC is not responsible for business decisions, transactions, data extraction, data modification, workflow automations, or any other downstream actions you take in reliance on AI outputs. Templates and selectors generated by the system may fail or produce inaccurate results without warning, especially as target websites change.
If you use LumaBrowser in a context where an incorrect output could cause harm — financial, legal, medical, safety-critical, or otherwise — you must independently verify every action before it runs.
To the maximum extent permitted by law, we disclaim all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, and title, and any warranties that the software will be uninterrupted, error-free, secure, or that outputs will be accurate or reliable. You use the software at your own risk.
To the maximum extent permitted by law, Lumabyte, LLC and its officers, members, employees, and contractors are not liable for any indirect, incidental, special, consequential, punitive, or exemplary damages, or for lost profits, lost revenue, lost data, lost goodwill, business interruption, procurement of substitute services, or reputational harm, arising out of or related to your use of LumaBrowser, AI outputs produced by it, or this website — even if we have been advised of the possibility of such damages, and regardless of the legal theory asserted (contract, tort, negligence, strict liability, or otherwise).
To the maximum extent permitted by law, our total aggregate liability for all claims arising out of or related to these terms, the software, or the website will not exceed the greater of:
For Community-tier and other non-paying users, the cap is a flat $100 USD. This cap is the full extent of our financial exposure and applies in the aggregate across all claims; it is not multiplied per incident, per user, per machine, or per feature.
The exclusions and limits in this Section 9 form an essential basis of the bargain between you and Lumabyte, LLC, and they apply even if a limited remedy fails its essential purpose.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages, so some of the above may not apply to every user. In those jurisdictions, our liability is limited to the smallest extent permitted by law.
These terms are governed by the laws of the State of Ohio, United States, without regard to its conflict-of-laws rules. Any disputes not resolved informally will be brought exclusively in the state or federal courts located in the State of Ohio, and you consent to personal jurisdiction and venue in those courts.
If you are a consumer resident in a jurisdiction with mandatory consumer-protection rules, nothing in these terms overrides those rules.
We may update these terms over time — for example, when we add features, change pricing models, or clarify language. The "Last updated" date at the top of this page always reflects the most recent change.
If a change materially affects your rights or obligations, we'll notify active paid subscribers by email before it takes effect. Your continued use of LumaBrowser after an update means you accept the new terms.
