The Agreement consists of, in order of priority: (1) the Order Form / subscription page, (2) these Terms, (3) the Data Processing Addendum (DPA), (4) the Privacy Policy, (5) the Acceptable Use Policy (AUP), (6) the list of Subprocessors. In case of conflict, the order above prevails.

3. Subscription, Term, Renewal

Access is provided via a subscription defined in the Order Form (the "Subscription Plan") for the subscription term agreed in that document.

Unless otherwise stated, the subscription automatically renews for the same term, unless either party gives prior notice. Lambda Vision may update the Services without materially degrading the current Plan.

4. Access and Support

Subject to payment of the Fees, Lambda Vision grants a non-exclusive, non-transferable, non-sublicensable right to use the Services for the Customer's internal needs and by its Users.

Email support is available Monday through Friday at support@solsice.com.

5. Prohibited Uses

The Customer must not (and must not permit any third party to): (i) resell, rent, or sublicense the Services; (ii) circumvent the limits of the Plan; (iii) impair security or attempt unauthorized access; (iv) reverse engineer; (v) violate the law, third-party rights, or the AUP; (vi) use the Services to create a competing service; (vii) introduce malware, overload, or disrupt the Services. Each User must use unique, non-shared credentials. The Customer remains responsible for the activity of its Users.

  • DPA: Lambda Vision's DPA applies to such processing in accordance with the GDPR.
  • Privacy Policy: transparently describes the processing carried out by Lambda Vision.

  • Unstructured personal data: personal data may be sent to Lambda Vision by the Customer. By default, if personal data is transmitted to Lambda Vision via a Solsice application or via the API, such personal data is considered unstructured personal data. The Customer is solely responsible for ensuring that the processing of unstructured personal data uploaded to the Services by the Customer or User complies with applicable data protection laws.
  • Confidentiality: each party protects the other's confidential information and uses it only for the performance of the Agreement; disclosures are permitted to professional advisors bound by obligations and where required by law.

  • Customer feedback: may be freely used by Lambda Vision to improve the Services.
  • Usage Data: Lambda Vision may (i) collect, analyze, and otherwise internally process Usage Data for its operational needs, in particular for security and analytics, in order to improve and optimize the Services, or for other development, diagnostic, and remediation purposes related to the Services or other Lambda Vision products or services, and (ii) disclose Usage Data only in aggregated and/or anonymized form as part of its business, in a manner that does not allow identification of the Customer or any of its Users.
  • Lambda Vision IP: the platform, software, documentation, trademarks, and any deliverables remain the property of Lambda Vision. No rights are granted beyond the license to use described above.

Lambda Vision warranties. During the Subscription Term, Lambda Vision warrants that: (a) the Services will operate substantially as described in the Documentation; and (b) the Agreement provides for appropriate measures to protect the security, confidentiality, and integrity of Customer Data.

If Lambda Vision fails to meet these warranties and the Customer notifies Lambda Vision within 30 days, Lambda Vision will (i) correct the Services or (ii) terminate the Agreement and refund unused Fees.

Customer warranties. The Customer warrants that: (a) it has the necessary rights and consents for Lambda Vision to process the Customer Data; (b) it will use the Services lawfully and in compliance with this Agreement; and (c) it will comply with the terms of any third-party services it connects to Solsice.

Disclaimer. Except as expressly stated above, the Services and Documentation are provided "as is". Lambda Vision disclaims all other warranties, express or implied, including non-infringement, merchantability, fitness for a particular purpose, accuracy, or uninterrupted availability.

10. Indemnification

By Lambda Vision: defense/indemnification of the Customer against third-party IP infringement claims arising from the Services, with corrective measures (license, modification, replacement, pro-rata refund). Customary exclusions apply (misuse, unintended combinations, third-party modifications, obsolete versions, Customer Data, third-party services).

By the Customer: defense/indemnification of Lambda Vision for claims related to the Customer Data, unlawful or non-compliant use, or third-party integrations enabled by the Customer. Procedure: prompt notification, the indemnifying party controls the defense, reasonable cooperation.

11. Force Majeure and Hardship

Neither party is liable for a failure caused by a force majeure event. If it lasts 90 days or more, the other party may terminate upon notice.

Hardship (French Civil Code art. 1195): a party may request renegotiation; failing agreement within a reasonable time, either party may terminate without charge.

12. Limitation of Liability

Unlimited liability. Nothing in this Agreement limits liability for: (i) death or personal injury caused by negligence; (ii) fraud; (iii) infringement of Lambda Vision's intellectual property; (iv) payment obligations; or (v) any liability that cannot be excluded by law.

Limitations. Neither party is liable for indirect or consequential damages such as loss of profits, revenue, goodwill, data, or system availability.

Mitigation by the Customer. The Customer is responsible for maintaining backups, monitoring its systems, and promptly reporting issues. Lambda Vision's liability for data loss is limited to recovery efforts that would have been possible if the Customer had implemented appropriate backups.

Liability cap. Except in the cases above, each party's total liability under this Agreement is capped at 100% of the subscription fees paid (or due) during the 12 months preceding the claim. Multiple claims will not increase this cap.

Risk allocation. These limits reflect the agreed allocation of risk and form an essential basis of the pricing of the Services.

13. Suspension

Lambda Vision may suspend all or part of the Services (with notice as soon as reasonably possible) if: (i) material breach, (ii) risk to the integrity/security of the service or to other customers, (iii) legal requirement, or (iv) suspected unauthorized access.

Upon termination:

  • access rights end;
  • clauses that by their nature must survive continue to apply (payment, confidentiality, IP, limitation of liability, governing law, etc.).

15. Beta and Free Trials

Under certain conditions, beta features or free trials may be provided without warranty. Where applicable, they may be modified or discontinued at any time. Service levels do not apply by default.
