Pre-release software terms

RadarFlow Studio Beta Software Agreement

Effective date: July 10, 2026 (supersedes the April 3, 2026 version)

This agreement applies to pre-release versions of the RadarFlow Studio radar software (which runs on a supported edge computer and is operated from your browser), related cloud features, documentation, sample pipelines, and associated materials (collectively, the "Beta Software"). It supplements Sigma0 LLC's Terms of Service. If there is a conflict, this Beta Software Agreement controls for the Beta Software.

1. Limited Beta License

Subject to this agreement, Sigma0 LLC grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Beta Software solely for internal evaluation, testing, feedback, and internal research and development purposes. The Beta Software is provided for pre-release evaluation only and is not licensed for production, safety-critical, or commercial deployment.

Without limiting the foregoing, the Beta Software is not designed, tested, or licensed for use in any application where failure, inaccuracy, or interruption could lead to death, personal injury, or physical or environmental damage — including life-safety, collision-avoidance, aviation or drone sense-and-avoid, weapons, autonomous-vehicle, medical, or security-screening applications ("High-Risk Uses"). You will not use the Beta Software for High-Risk Uses. You acknowledge that detections, tracks, classifications, and other outputs of the Beta Software are experimental and may be inaccurate, incomplete, or absent, and you assume all risk of any reliance on them.

2. Pre-Release Nature

The Beta Software is unfinished, experimental, and may contain defects, security issues, incomplete features, performance instability, data-loss bugs, and breaking changes. Sigma0 LLC may modify, suspend, or discontinue the Beta Software (or any feature of it) at any time, with or without notice, and has no obligation to make any beta feature generally available. However, any suspension or termination of your access to the Beta Software is subject to the notice and data-export provisions of Section 12 (Term and Termination).

3. Use Restrictions

You may not, except to the extent the following restrictions are prohibited by applicable law:

• copy, sell, rent, lease, sublicense, distribute, or otherwise transfer the Beta Software;
• reverse engineer, decompile, disassemble, or attempt to derive source code, trade secrets, or non-public interfaces;
• remove or alter copyright, trademark, attribution, or proprietary notices;
• publish benchmarks or performance comparisons of the Beta Software before it is made generally available, without Sigma0 LLC's prior written consent;
• use Sigma0 LLC's confidential information, or copy the Beta Software, to build or help others build a product that competes with the Beta Software;
• use the Beta Software for unlawful, export-restricted, or harmful purposes.

Nothing in this agreement restricts you from developing radar products, radar signal-processing software, or related technology — independently or for any employer or client — so long as you do not use Sigma0 LLC's confidential information or copy the Beta Software. General skills, knowledge, and experience you gain from using the Beta Software are not restricted.

The Beta Software includes third-party and open-source components licensed under their own terms, identified in the notices file accompanying the Beta Software. Nothing in this agreement limits any rights you have under those licenses with respect to those components, and those licenses govern those components to the extent of any conflict.

4. Ownership and Intellectual Property

The Beta Software is licensed, not sold. Sigma0 LLC and its licensors retain all right, title, and interest in and to the Beta Software (excluding your User Content), including all source code, object code, algorithms, models, visual designs, documentation, interfaces, updates, and derivative works of the Beta Software, together with all copyright, patent, trade secret, trademark, and other intellectual property rights.

Except for the limited license expressly granted above, no rights are granted to you by implication, estoppel, or otherwise.

For clarity, you retain all right, title, and interest in any radar pipelines, configurations, recordings, captured radar datasets, and other content you create using the Beta Software ("User Content"). Nothing in this agreement transfers ownership of your User Content to Sigma0 LLC.

The Beta Software is "commercial computer software" and "commercial computer software documentation" under FAR 12.212 and DFARS 227.7202. Any use by or for the U.S. Government is subject solely to the terms of this agreement.

5. Feedback

If you provide suggestions, ideas, issue reports, feature requests, evaluation notes, workflow examples, or other feedback regarding the Beta Software, you grant Sigma0 LLC a perpetual, irrevocable, worldwide, royalty-free, fully paid-up, sublicensable, and transferable license to use, modify, reproduce, disclose, and incorporate that feedback into its products and services without restriction, attribution, or compensation. Sigma0 LLC may independently develop features similar to any feedback without obligation to you. Feedback does not include your User Content or your confidential information; if you attach proprietary materials (such as your own pipeline configurations or datasets) to a report, Sigma0 LLC receives rights only in the suggestions and ideas conveyed, not ownership of those materials. You agree not to provide feedback you know to be subject to third-party rights or confidentiality obligations. Sigma0 LLC will not publicly attribute feedback to you or your organization without your prior consent.

6. Confidentiality

Non-public aspects of the Beta Software, including unreleased features, performance characteristics, screenshots of non-public functionality, roadmaps, and technical documentation, are Sigma0 LLC confidential information. You agree not to disclose or share that confidential information with third parties without Sigma0 LLC's prior written consent, except to your employees or contractors who need access for the permitted evaluation use and who are bound by confidentiality obligations at least as protective as these terms.

Confidential information does not include information that is or becomes publicly available through no fault of yours, was rightfully known to you without restriction before disclosure, is rightfully received from a third party without a duty of confidentiality, or is independently developed without use of Sigma0 LLC's confidential information. If you are legally compelled to disclose confidential information, you will, where lawful, give Sigma0 LLC prompt notice and disclose only what is required. You acknowledge that unauthorized use or disclosure of Sigma0 LLC's confidential information may cause irreparable harm for which monetary damages are inadequate, and Sigma0 LLC may seek injunctive relief in addition to other remedies.

Sigma0 LLC will likewise protect your non-public information that it receives in connection with the beta — including your User Content, radar configurations, and evaluation environment details received through cloud features, support channels, or diagnostics — using at least reasonable care, and will access and use it only to provide, support, secure, and improve the Beta Software.

You may disclose the fact that you are participating in the RadarFlow Studio beta. You may publicly share screenshots, videos, and descriptions of features that Sigma0 LLC has publicly announced or documented, provided you identify the software as pre-release; publishing benchmark or performance results remains subject to Section 3.

These confidentiality obligations continue for two (2) years after termination of this agreement, except that obligations regarding information that constitutes a trade secret under applicable law continue for as long as that information remains a trade secret.

Nothing in this agreement prohibits you from reporting potential violations of law to any governmental agency or from making disclosures protected under whistleblower provisions of applicable law. You are not required to notify Sigma0 LLC of any such report or disclosure.

7. Radar Operation and Regulatory Compliance

The Beta Software does not include a radio transmitter and does not confer any spectrum license or equipment authorization. You are solely responsible for the selection, configuration, and lawful operation of any radar or RF hardware used with the Beta Software, including compliance with all applicable spectrum, equipment-authorization, and radio-licensing rules (in the United States, the FCC's rules) and analogous laws elsewhere, and for any interference caused by your transmissions. Sigma0 LLC makes no representation that any output, default setting, or sample pipeline complies with any regulatory limit.

8. Data, Security, and Backups

You are responsible for your own data, device configuration, retention, and backups. Do not rely on the Beta Software as your sole system of record. Sigma0 LLC is not responsible for lost recordings, corrupted captures, broken workflows, or interruption of evaluation activities arising from the use of pre-release software. Our collection and use of personal data in connection with the Beta Software is governed by our Privacy Policy.

The Beta Software may collect anonymized usage telemetry, crash reports, and diagnostic data to help improve the product — limited to categories such as application version, feature usage events, performance metrics, crash stack traces, and hardware model. Telemetry and crash reporting are designed to exclude your User Content (including captured radar datasets); if fragments of such data are incidentally captured in a crash report, Sigma0 LLC will treat them as your confidential information under Section 6, use them only to diagnose the failure, and delete them when no longer needed. You may opt out of telemetry collection through the application settings. Details of the specific data collected are described in our Privacy Policy.

9. Your Responsibilities and Indemnity

You are responsible for your use of the Beta Software and for your User Content. You will defend Sigma0 LLC against third-party claims, and indemnify it for resulting damages, penalties, costs, and reasonable attorneys' fees finally awarded or agreed in a settlement, to the extent arising from (a) your use of the Beta Software in violation of this agreement or applicable law, including any High-Risk Use; (b) any claim that your User Content infringes or misappropriates a third party's rights or violates applicable law, except to the extent the claim arises from Sigma0 LLC's handling of your User Content in violation of this agreement; or (c) your operation of radar or other RF hardware, including violations of spectrum, licensing, or emissions regulations and interference claims. You will control the defense and settlement of any indemnified claim, provided any settlement fully releases Sigma0 LLC; Sigma0 LLC will notify you of any such claim (a failure to notify relieves your obligations only to the extent you are materially prejudiced), will reasonably cooperate at your expense, and may participate in the defense with its own counsel at its own cost. This section does not apply to the extent a claim arises from Sigma0 LLC's gross negligence or willful misconduct.

10. No Warranty

THE BETA SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, OR QUIET ENJOYMENT. SIGMA0 LLC DOES NOT WARRANT THAT THE BETA SOFTWARE WILL BE ERROR-FREE, SECURE, OR AVAILABLE WITHOUT INTERRUPTION.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIGMA0 LLC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, BUSINESS, REVENUE, PROFITS, GOODWILL, OR PROCUREMENT OF SUBSTITUTE TECHNOLOGY, ARISING OUT OF OR RELATING TO THE BETA SOFTWARE OR THIS AGREEMENT, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, EXCEPT FOR DIRECT DAMAGES CAUSED BY SIGMA0 LLC'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

SIGMA0 LLC'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE BETA SOFTWARE OR THIS AGREEMENT SHALL NOT EXCEED ONE HUNDRED U.S. DOLLARS ($100) OR THE TOTAL AMOUNT YOU HAVE PAID TO SIGMA0 LLC IN THE TWELVE MONTHS PRECEDING THE CLAIM, WHICHEVER IS GREATER. THE FOREGOING CAP DOES NOT APPLY TO DAMAGES CAUSED BY SIGMA0 LLC'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO THESE LIMITATIONS MAY NOT APPLY TO YOU.

12. Term and Termination

This agreement begins when you first accept it or access the Beta Software and continues until terminated. You may terminate this agreement at any time by ceasing use of the Beta Software and deleting all copies in your possession. Sigma0 LLC may suspend or terminate your access at any time for any reason on five (5) days' written notice, except that Sigma0 LLC may suspend or terminate immediately for a breach that is incapable of cure, a breach involving confidentiality, intellectual property, or export control, or where reasonably necessary to address a security risk or legal-compliance concern. For any other breach, Sigma0 LLC will provide ten (10) days' written notice and an opportunity to cure before termination.

Except where termination is for your uncured or incurable breach or for a security or legal-compliance reason, Sigma0 LLC will provide you with not less than fourteen (14) days after termination to export any User Content stored in Sigma0-hosted cloud features. During that export period, the license in Section 1 continues solely to the extent necessary to retrieve your User Content. User Content stored on your own hardware remains yours and in your possession, and nothing in this agreement restricts your access to it. After the export period, you must stop using the Beta Software and delete or destroy all copies of the Beta Software and Sigma0 LLC confidential information in your possession, except to the extent retention is required by law. This deletion requirement does not apply to your User Content.

Sections 4 (Ownership and Intellectual Property), 5 (Feedback), 6 (Confidentiality), 9 (Your Responsibilities and Indemnity), 10 (No Warranty), 11 (Limitation of Liability), 12 (Term and Termination, as to post-termination obligations), 13 (Export and Compliance), 14 (Governing Law and Dispute Resolution), and 15 (General), and any other provision that by its nature should survive, survive termination of this agreement.

13. Export and Compliance

The Beta Software and related technology are subject to U.S. export control and sanctions laws, including the Export Administration Regulations. You will not export, re-export, transfer, or provide access to the Beta Software, directly or indirectly, to any embargoed or sanctioned jurisdiction, to any person on a U.S. government restricted-party list, or for any prohibited end use (including military-intelligence, missile, nuclear, or chemical or biological weapons end uses or end users) without required government authorization. You represent that you are not located in, ordinarily resident in, owned or controlled by, or acting on behalf of any such jurisdiction or party.

You will not upload, transmit, or otherwise provide to Sigma0 LLC — including through cloud features, support channels, or feedback — any technical data controlled under the International Traffic in Arms Regulations (ITAR) or other export-controlled technical data, and you will not use the Beta Software to design or develop defense articles. You agree to comply with all applicable laws and regulations in your use of the Beta Software.

14. Governing Law and Dispute Resolution

This agreement is governed by the laws of the State of Iowa, United States, without regard to conflict-of-law principles.

Any dispute arising out of or relating to this agreement or the Beta Software will be resolved by binding individual arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules — or, if you are an individual using the Beta Software for personal, non-commercial purposes, its Consumer Arbitration Rules — seated in Waterloo, Iowa. Hearings may be conducted by video conference at the arbitrator's discretion. Either party may instead bring an individual claim in small claims court. Either party may bring claims for intellectual property infringement or breach of confidentiality in the state or federal courts located in Black Hawk County, Iowa, and both parties consent to personal jurisdiction and venue there. If you are an individual, you may opt out of this arbitration provision by emailing legal@sigma0.com within thirty (30) days of first accepting this agreement.

ALL DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. If this class-action waiver is held unenforceable as to a particular claim, that claim (and only that claim) will proceed in court.

15. General

Entire agreement. This agreement, together with the Terms of Service and Privacy Policy it references, is the entire agreement between you and Sigma0 LLC regarding the Beta Software and supersedes any prior or contemporaneous understandings about the Beta Software — except that any separately executed agreement between you and Sigma0 LLC (including any non-disclosure agreement) remains in effect and controls to the extent it is more protective of either party's confidential information.

Changes. Sigma0 LLC may update this agreement by posting a revised version and providing notice at least fourteen (14) days before it takes effect. Changes apply prospectively only. If you do not agree to a change, you may terminate this agreement before the change takes effect and receive the export period described in Section 12.

Notices. Sigma0 LLC may give notice by email to the address associated with your account or waitlist registration, or by prominent notice in the application; notice is deemed given when sent or posted. You may give notice by email to legal@sigma0.com. Each party is responsible for keeping its contact information current.

Assignment. You may not assign or transfer this agreement without Sigma0 LLC's prior written consent. Sigma0 LLC may assign this agreement to an affiliate or in connection with a merger, acquisition, or sale of all or substantially all of its assets.

Force majeure. Neither party is liable for delay or failure to perform (other than payment obligations, if any) caused by events beyond its reasonable control, including natural disasters, outages of third-party infrastructure, war, or governmental action.

No waiver. A party's failure to enforce any provision of this agreement is not a waiver of its right to do so later.

Severability. If any provision of this agreement is held invalid or unenforceable by a court of competent jurisdiction, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible, and all remaining provisions will continue in full force and effect.
