Terms of Service

Last updated: April 24, 2026

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.

1. Acceptance

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.

2. What we provide

Lumabyte, LLC ("Lumabyte," "we," "us," or "our") builds and operates:

  • LumaBrowser — a downloadable Electron-based browser with notification-to-webhook interception, an AI agent loop, a Model Context Protocol (MCP) server, a Chrome DevTools Protocol (CDP) driver, page template extraction, and related extensions.
  • lumabyte.com — this website, including documentation, the downloads manifest, billing endpoints, and the shared public template repository.
  • Open-source libraries — such as ResonantJs and OpenGridJs, which are governed by their own open-source licenses and are not covered by these terms except where explicitly referenced.

LumaBrowser is offered in three tiers:

  • Community — free, single-user, contributes anonymized template data to the shared repository.
  • Pro — paid subscription, private templates, no telemetry contribution.
  • Enterprise — paid subscription, multi-instance, self-hosted Docker deployment, private templates, no telemetry contribution.

Features, pricing, and tier boundaries may change. We'll post current pricing at /pricing.

3. Accounts and license keys

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:

  • Keeping your license key confidential. Treat it like a password.
  • The number of active installations matching your tier's seat count.
  • Any activity performed under your license.

If a key is compromised, email us (see Contact) and we will revoke and reissue it.

4. Acceptable use

LumaBrowser is a general-purpose automation tool. You are responsible for how you use it. You agree not to:

  • Use LumaBrowser to break the terms of service of websites you don't own or aren't authorized to automate against.
  • Send spam, phishing, or unsolicited messages through automation.
  • Harvest personal data without a lawful basis.
  • Use LumaBrowser to access systems you are not authorized to access, or to evade technical access controls (rate limits, bot detection) in ways that violate applicable law.
  • Attempt to interfere with the stability of lumabyte.com or our infrastructure (e.g., denial-of-service, excessive API abuse).
  • Use automated processes to overwhelm the public template repository, poison it with junk data, or scrape it in bulk outside the intended API.

We may suspend or revoke access to paid tiers if we reasonably believe these rules are being broken.

5. Payment, renewal, and refunds

Billing

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.

Renewal

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.

Price changes

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.

Refunds

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.

6. Intellectual property

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:

  • Reverse engineering, decompiling, or disassembling the software, except where that prohibition is not permitted by applicable law.
  • Commercial redistribution of the binaries or source.
  • Reselling access to a single license across multiple customers (i.e., offering LumaBrowser as a managed service to third parties without an explicit reseller agreement).
  • Removing or altering copyright notices, license terms, or attribution.

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.

7. Termination

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.

8. Disclaimers

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 automates web pages. Web pages change. Automations may break. We don't guarantee selectors, templates, or agent loops will continue to work against third-party sites.
  • LumaBrowser integrates with LLM providers you configure (Anthropic, OpenAI, local models, etc.). We are not responsible for their uptime, accuracy, output quality, content, or pricing.
  • The shared template repository is crowd-sourced and best-effort. Templates returned by the public API may be stale or incorrect.

9. Limitation of liability

AI and automation outputs

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.

No warranties

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.

Excluded damages

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).

Aggregate cap

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:

  • the fees you actually paid Lumabyte, LLC in the twelve (12) months immediately preceding the event that gave rise to the claim, or
  • $100 USD.

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.

Savings clause

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.

10. Governing 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.

11. Changes to these terms

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.
