1. Acceptance and Scope of Terms

1.1. These Terms apply to all versions of the Software, updates, additional modules, and associated documentation made available by the Licensor.

1.2. Use of the Software is also governed by our Privacy Policy, which details how data is handled within the application.

2.1. License Grant: Licensor grants User a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable license to install and execute the Software on compatible Apple devices owned or controlled by User, as permitted under Mac App Store rules.

2.2. Usage Restrictions: Except as expressly permitted by applicable law, User agrees not to:

  • Copy, modify, adapt, translate, or create derivative works based on the Software;
  • Reverse engineer, decompile, disassemble, or attempt to extract the source code of the Software;
  • Sell, rent, lease, sublicense, redistribute, or make the Software available to third parties;
  • Remove, alter, or obscure any copyright notices, trademarks, or proprietary identifiers contained within the Software.

3. Nature of Software and Local Storage

3.1. Lumen Flow is a software environment operated locally on the User’s device for designing, running, and managing flows that make HTTP requests and interact with APIs.

3.2. All credentials, workspaces, request collections, keys, and execution histories are processed and stored on the User’s local device. Where User enables Git Sync or iCloud Sync, data may also be stored as described in the Privacy Policy. Licensor maintains no proprietary servers for storing or routing such content.

4. Intellectual Property

4.1. The Software, including its source code, architecture, design, trademarks, logos, icons, and visual elements, is the exclusive property of Licensor and protected by international intellectual property and copyright laws.

4.2. All data, request flows, scripts, and content created or imported by User through the Software remain the exclusive property of User.

5. Subscriptions and Financial Transactions

5.1. Acquisition of licenses, subscriptions, or additional features for the Software is processed exclusively through the Mac App Store. The price, billing period, any trial period, included features, and applicable renewal terms will be presented on the App Store purchase screen before User confirms the purchase.

5.2. Billing, charges, automatic renewals, refunds, and cancellations are managed by Apple under the applicable App Store terms and the information presented at purchase. Subscriptions may be managed or cancelled in User’s Apple Account settings. Licensor does not collect or store banking or payment card details.

6. Acceptable Use and User Responsibility

6.1. User is solely responsible for the legality and appropriateness of network calls, parameters, headers, HTTP requests, and data transmitted through the use of the Software.

6.2. It is strictly prohibited to use the Software to:

  • Perform unauthorized access to third-party systems, servers, or networks;
  • Transmit unlawful, malicious, or rights-infringing content;
  • Execute Denial of Service (DoS/DDoS) attacks or unauthorized vulnerability scanning;
  • Violate the terms of service or usage policies of consumed third-party APIs.

7. Disclaimer of Warranties

7.1. To the maximum extent permitted by applicable law, the Software is provided “AS IS” and “AS AVAILABLE.” This provision does not exclude statutory warranties, remedies, or other mandatory protections afforded to User under applicable law.

7.2. Subject to mandatory legal rights, Licensor does not warrant that the Software will meet User’s particular requirements, operate uninterrupted or error-free, or remain compatible with every operating-system or third-party API update.

8. Limitation of Liability

8.1. To the maximum extent permitted by applicable law, Licensor shall not be liable for indirect, incidental, special, consequential, punitive, or exemplary damages — including loss of data, operational failure, file corruption, or business interruption — arising out of or related to the use or inability to use the Software. This limitation does not exclude liability that cannot lawfully be excluded or limited.

8.2. User acknowledges that configuration and execution of HTTP requests are conducted at User’s sole responsibility and risk.

9. Third-Party Services and APIs

9.1. The Software enables interaction with services, servers, and APIs maintained by third parties. Licensor exercises no control over, does not evaluate, and assumes no responsibility for the content, availability, performance, or security practices of external services.

10. Modifications and Updates

10.1. Licensor reserves the right to update, modify, or discontinue features of the Software at any time for technical or security enhancements.

10.2. These Terms may be revised periodically. Material changes affecting User rights or obligations will be published on this page and, where feasible, identified in Mac App Store release notes at least 30 days before they take effect. User may stop using the Software and cancel any subscription before those changes take effect. Changes needed for security, legal compliance, or abuse prevention may take effect sooner, with notice published as soon as reasonably possible.

11. Termination

11.1. If User breaches these Terms, Licensor may suspend or terminate the license. Where reasonably possible, User will be notified and allowed a reasonable opportunity to cure the breach. Immediate suspension or termination may occur for unlawful use, security risks, serious infringement of third-party rights, or another situation requiring urgent action.

11.2. Upon termination, User must stop using the Software. Nothing in this clause limits User’s access to User’s own local data, to the extent permitted by law and technically available.

12. Mac App Store and Apple

12.1. These Terms are concluded between User and Licensor, and not with Apple. Apple has no obligation to furnish maintenance or support for the Software.
