End User License Agreement

Last Updated: March 2026

This End User License Agreement ("Agreement") is a binding legal agreement between you ("User") and Tanj iTech Pvt Ltd ("Company"), setting forth the terms and conditions governing your use of the DNV Viewer software application, including all updates, related documentation, and integrated services (collectively, the "Software").

By downloading, installing, or using the Software, you agree to be bound by the terms of this Agreement. If you do not agree to these terms, do not install or use the Software.

1. Grant of License

Subject to your compliance with the terms and conditions of this Agreement, Company grants you a limited, non-exclusive, non-transferable, revocable license to install and use the Software on supported operating systems (macOS, Windows) for your personal or internal business purposes, specifically for viewing DICOM images and generating preliminary radiological text reports.

2. Restrictions on Use

You agree not to:

  • Modify, translate, reverse engineer, decompile, or disassemble the Software.
  • Relicense, sell, rent, lease, or otherwise distribute the Software without prior written consent.
  • Use the Software in any manner that violates applicable local, state, national, or international laws, particularly those concerning patient privacy and healthcare data (e.g., HIPAA, GDPR), unless appropriate measures and safeguards are employed on your end.

3. Medical Disclaimer and Limitation of Liability

NOT FOR PRIMARY DIAGNOSTIC USE. NOT A CERTIFIED MEDICAL DEVICE. DNV Viewer is intended solely as a desktop image review and workflow assistance tool. It has NOT been certified, cleared, or approved as a medical device by any regulatory authority, including but not limited to: the U.S. Food and Drug Administration (FDA); the European Commission under EU Medical Device Regulation (MDR 2017/745); the Central Drugs Standard Control Organisation (CDSCO, India); the Therapeutic Goods Administration (TGA, Australia); Health Canada; or any equivalent body in any other jurisdiction. No regulatory submission has been made for this Software in any market.

Qualified Professional Use Only. The Software is intended exclusively for use by licensed, credentialed healthcare professionals — such as radiologists, physicians, or similarly trained clinical personnel — acting within their professional scope and in compliance with applicable professional standards. Use by unlicensed individuals, or use outside one's area of professional competence, is expressly prohibited. The institution or individual deploying the Software bears sole responsibility for ensuring that all users are appropriately qualified and authorised under applicable law.

Not for Emergency Use. The Software is not designed, validated, or intended for use in emergency, life-critical, or time-critical clinical situations. You must not rely on the Software as a primary or sole tool in any situation where a delay or error in interpretation could result in death, serious bodily harm, or irreversible patient harm.

Independent Clinical Judgment Required. The Software is not intended to replace, and must not be used to replace, the independent clinical judgment of a qualified healthcare professional. Every diagnosis, treatment decision, or medical conclusion reached with any assistance from the Software must be independently evaluated, verified, and approved by the responsible licensed clinician before being acted upon. The Company expressly disclaims all responsibility for any clinical outcome, adverse event, or patient harm arising from reliance on Software output without such independent professional oversight.

Regulatory Compliance is Your Responsibility. Depending on your jurisdiction and clinical context, your use of the Software may be subject to local medical device regulations, data protection laws, or healthcare compliance requirements (including, without limitation, HIPAA, GDPR, and India's Digital Personal Data Protection Act). You are solely and entirely responsible for determining whether your use complies with all applicable laws and for implementing any additional technical, organisational, or procedural safeguards required.

Assumption of Risk. By using the Software in any clinical context, you expressly acknowledge that you have read, understood, and accept this disclaimer in full, and you voluntarily assume all risks associated with such use. Use of the Software in violation of these terms — including use as a primary diagnostic tool, use in emergency situations, or use by unqualified individuals — constitutes a material breach of this Agreement and releases the Company from any and all liability resulting therefrom.

4. Artificial Intelligence (LLM) Capabilities

The Software includes integrated Artificial Intelligence capabilities (such as Chat and Report Rewriter), powered by external Large Language Models (LLMs) including GPT, Gemini, and Claude architectures, accessed via radiologyassistant.ai.

  • Informational Purposes Only: The AI features are designed to assist with report structuring, summarization, and workflow efficiency. Output generated by the AI must be carefully reviewed, verified, and approved by a qualified medical professional before being relied upon or finalized.
  • Hallucinations and Errors: LLMs are known to occasionally produce inaccurate or fabricated information ("hallucinations"). The Company makes no warranties regarding the accuracy, completeness, or clinical validity of AI-generated text.
  • Data Privacy and Prompts: Text you submit via the Chat or Rewriter is transmitted to secure servers solely to generate a response. To protect patient confidentiality, you must treat these fields like any shared external clinical tool — do not enter individually identifiable patient information such as full names, dates of birth, national ID numbers, or contact details. You are solely responsible for compliance with applicable privacy regulations (including HIPAA, GDPR, and the DPDP Act) when submitting any text to these features.
  • Third-Party AI Provider Policies: The underlying AI models are provided by third-party organisations (including OpenAI, Google, and Anthropic). Your use of AI-powered features is also subject to those providers' own terms of service and data handling policies. The Company makes no representations or warranties regarding the data practices of these third parties and is not liable for any data handling by them beyond what is contractually agreed.
  • No Sole Reliance on AI Output: AI-generated text must never be used as the sole basis for any clinical decision, patient communication, or medical record entry. All AI output requires mandatory independent review and written approval by a qualified licensed clinician before use.

5. Integration with radiologyassistant.ai

Certain premium or connected features rely on radiologyassistant.ai. Your use of these specific features may be subject to additional terms of service or subscription requirements dictated by that platform. You must possess valid authorization or subscription credentials to access specific AI models or extended capabilities through the Software.

6. Software Licensing

To ensure a secure and fair experience for all users, the Software uses standard licensing mechanisms. By using the Software, you agree to the following:

  • Device Registration: Your license is associated with the device it is installed on, as a safeguard against unauthorized sharing. If you need to move to a different machine, our support team is happy to assist with a transfer.
  • Background License Check: The Software performs occasional, lightweight background checks with our servers to keep your license active. This is a routine process and does not affect your normal workflow. The Software is designed to remain accessible during short offline periods.
  • Subscription Tiers: Access to certain AI models and advanced features is determined by your active subscription plan.
  • App Updates: Occasionally, an update may be required to maintain compatibility and security. You will be notified in-app and can update at your convenience.

7. Data and Privacy

We take data privacy seriously, particularly given the clinical context in which DNV Viewer is used. To be transparent about what is and is not collected:

  • No clinical data is ever collected. No DICOM images, pixel data, or patient records are transmitted to our servers at any point during normal use.
  • Anonymized diagnostics: The Software may send anonymized crash reports and general usage statistics to help us identify and fix issues. This data contains no personal or clinical information of any kind.
  • Analytics on web-based screens: Certain informational or account-related screens within the app may use standard web analytics tools to help us understand how users navigate the interface. This is limited to general interaction behaviour (e.g., page views, button clicks) and does not include any clinical or personally identifiable information.

8. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, CLINICAL ACCURACY, OR FITNESS FOR USE IN A MEDICAL OR DIAGNOSTIC CONTEXT. THE COMPANY DOES NOT WARRANT THAT THE SOFTWARE WILL OPERATE UNINTERRUPTED OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SOFTWARE IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY EXPRESSLY DISCLAIMS ALL LIABILITY FOR: (A) PERSONAL INJURY OR DEATH ARISING FROM RELIANCE ON THE SOFTWARE OR ITS OUTPUT; (B) ANY ADVERSE PATIENT OUTCOME, MISSED DIAGNOSIS, OR DELAYED TREATMENT ATTRIBUTABLE TO USE OF THE SOFTWARE; AND (C) ANY LOSS OR CORRUPTION OF CLINICAL DATA. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES OR LIMITATIONS ON APPLICABLE STATUTORY RIGHTS OF A CONSUMER, SO SOME OF THE ABOVE EXCLUSIONS AND LIMITATIONS MAY NOT APPLY TO YOU.

9. Indemnification

You agree to defend, indemnify, and hold harmless the Company and its officers, directors, employees, contractors, and agents from and against any and all third-party claims, liabilities, damages, judgments, awards, losses, costs, and expenses (including reasonable legal fees) arising out of or in connection with: (a) your use or misuse of the Software, including use in violation of this Agreement; (b) your use of the Software in a clinical, diagnostic, or patient-care context, including any adverse patient outcome or personal injury claim attributable — in whole or in part — to reliance on Software output; (c) your failure to comply with any applicable healthcare, data protection, or medical device regulation in your jurisdiction; (d) your breach of any representation, warranty, or obligation under this Agreement; or (e) any claim by a third party (including patients or their representatives) arising from your use of the Software.

10. Termination

This Agreement is effective until terminated. Your rights under this Agreement will terminate automatically without notice from the Company if you fail to comply with any of its terms. Upon termination, you must immediately cease all use of the Software and destroy all copies in your possession or control. Sections 3, 8, 9, and 11 shall survive any termination or expiry of this Agreement.

11. Governing Law and Dispute Resolution

This Agreement shall be governed by and construed in accordance with the laws of India, specifically the laws of the state in which Tanj iTech Pvt Ltd is registered, without giving effect to any conflict-of-law principles. Any dispute, controversy, or claim arising out of or relating to this Agreement, or its breach, termination, or validity, shall first be attempted to be resolved through good-faith negotiation between the parties.
