  1. Any signed Purchase Order or Enterprise Agreement (for Enterprise Deployments);
  2. Any applicable Special Terms and Conditions (for Enterprise Deployments);
  3. These Terms of Service and their appendices;
  4. The applicable SLA;
  5. The DPA (where personal data processing applies);
  6. The Documentation.

Except as specified in section 2.4 below, these Terms, together with the documents listed above, constitute the entire agreement between LightOn and the Customer (hereinafter “the Parties”) and supersede all prior representations, negotiations, and agreements relating to the Service. Any general purchasing conditions or standard terms of the Customer are expressly excluded.

2.3 Amendments

LightOn reserves the right to amend these Terms in accordance with Article 20 – Modifications to the Terms. Amendments to Enterprise Agreements require a written addendum signed by both Parties.

2.4 Special conditions, prior and specific agreements

Where a Customer (or any of its affiliates) is party to a separate signed agreement with LightOn governing the use of any LightOn product (including Paradigm enterprise deployments), that agreement governs the relationship for that product.

  • Access and use the Console and its AI Features via the APIs and web interface;
  • Integrate the API outputs into the Customer’s own applications and workflows;
  • Make copies of the Documentation strictly necessary for the Customer’s internal use.
This license is granted solely for the Customer’s internal professional purposes and for integration into Customer-built products or services.

  • Circumvent or attempt to circumvent any technical access controls, rate limits, or usage restrictions;
  • Use the Service in a manner that would infringe any third party’s intellectual property rights.

8.3 LightOn’s intellectual property

All intellectual property rights in and to the Console, the AI Features, LightOn’s models, the Documentation, and any related technology remain the exclusive property of LightOn. Nothing in these Terms transfers any intellectual property right to the Customer other than the limited license granted in Article 8.1.

  • Output Data: the Customer owns Output Data generated in response to its inputs, subject to any third-party rights and to the limitations described in 8.6 License granted to LightOn below.
The Customer acknowledges that the AI models provided via the Console are trained on large corpora of text and data, which may include material protected by third-party intellectual property rights. As a result:
  • Output Data may reflect patterns, phrasing, or structures statistically derived from such training material, and may, in certain cases, bear similarity to pre-existing copyrighted works, without LightOn necessarily being aware of this at the time of generation;
  • Due to the statistical nature of generative AI, Output Data produced in response to similar or identical inputs may be substantially similar or identical across different customers. LightOn makes no warranty of exclusivity or uniqueness with respect to any Output Data.
The Customer is solely responsible for reviewing Output Data before any use, publication, or commercial exploitation, and for conducting any intellectual property clearance it deems necessary. LightOn disclaims all liability arising from any third-party intellectual property infringement claim relating to Output Data, where such claim results from the Customer’s use, reproduction, or distribution of that Output Data. The Customer shall indemnify LightOn against any such third-party claim pursuant to Article 17.5. Nothing in this clause limits LightOn’s obligations under the EU AI Act, including its transparency obligations regarding training data under Article 53(1)(d) of Regulation (EU) 2024/1689.

8.6 License granted to LightOn

To provide the Service, the Customer grants LightOn and its authorised sub-processors a non-exclusive, worldwide, royalty-free, limited license to host, process, store, cache, and transmit Customer Data solely to the extent necessary to deliver the Service, enforce these Terms, and comply with applicable law. This license terminates upon deletion of Customer Data as provided in Article 12 – Data Portability and Deletion. LightOn does not use Customer Data to train, fine-tune, or improve any general-purpose AI models, except where the Customer has expressly opted into such use in writing or through a clearly presented consent mechanism in the Console.

Article 19 – Governing Law and Dispute Resolution

19.1 Governing law

These Terms and any disputes arising from or in connection with them shall be governed by and construed in accordance with French law, without regard to its conflict of laws rules.

19.2 Amicable resolution

In the event of a dispute, the Parties agree to use their best efforts to resolve it amicably. Either Party may initiate the amicable resolution process by giving written notice to the other Party describing the dispute in reasonable detail. The Parties shall negotiate in good faith for a period of 30 days from the date of such notice.

19.3 Jurisdiction

If the Parties fail to resolve the dispute amicably, the courts of Paris, France, shall have exclusive jurisdiction, subject to any mandatory jurisdictional rules applicable under French or EU consumer protection law.

19.4 Mediation

Without prejudice to the foregoing, the Parties may at any time agree to submit the dispute to mediation before a mediator appointed by mutual agreement or under the rules of the Centre de Médiation et d’Arbitrage de Paris (CMAP).

Article 20 – Modifications to the Terms

LightOn reserves the right to modify these Terms at any time. Modifications will be notified to the Customer by:
  • Email to the registered account address; and/or
  • A prominent notice in the Console dashboard.
For material changes, LightOn will provide at least 30 days’ advance notice. The Customer’s continued use of the Service after the effective date of the modification constitutes acceptance of the modified Terms. If the Customer does not accept the modified Terms, it may terminate its account before the effective date of the modification, in which case:
  • For paid annual subscriptions: LightOn will provide a pro-rata refund of prepaid fees for the unused period;
  • For monthly and usage-based plans: no refund is owed for charges already incurred.

Article 21 – Miscellaneous

21.1 Entire agreement

These Terms (together with the documents referred to herein) constitute the entire agreement between the Parties with respect to the Service and supersede all prior agreements and representations.

21.2 Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, that provision shall be modified to the minimum extent necessary to make it enforceable. The remaining provisions shall continue in full force.

21.3 Waiver

The failure of either Party to enforce any provision of these Terms shall not constitute a waiver of that Party’s right to enforce such provision in the future.

21.4 Assignment

The Customer may not assign or transfer any of its rights or obligations under these Terms without LightOn’s prior written consent. LightOn may assign its rights and obligations under these Terms to a successor entity in the event of a merger, acquisition, or sale of substantially all of its assets, provided it gives the Customer notice and the successor entity assumes all obligations under these Terms.

21.5 Force majeure

Neither Party shall be liable for delays or failures in performance resulting from circumstances beyond its reasonable control, including but not limited to: acts of God, natural disasters, epidemics, pandemics, war, terrorism, government orders, cyberattacks not attributable to the Party’s negligence, or failures of third-party infrastructure providers. The affected Party must promptly notify the other and use its best efforts to mitigate the impact.

21.6 Sub-processors and third parties

LightOn may use sub-processors to deliver the Service, as listed in the DPA. LightOn remains responsible for the acts and omissions of its sub-processors to the same extent as for its own acts and omissions under these Terms.
