Terms of Service

1. Service Description

OpenCorpo Compliance (the “Service”) is an API service provided by Klart AI SAS (“Klart AI,” “we,” “us,” or “our”), a company incorporated under French law, registered in Paris, France. The Service enables customers to add C2PA provenance metadata, invisible watermarks, and content fingerprints to AI-generated images for the purpose of compliance with EU AI Act Article 50 and related regulations.

2. Acceptance of Terms

By accessing or using the Service, you agree to be bound by these Terms of Service (“Terms”). If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. User Obligations

You agree to:

• Use the Service only for lawful purposes and in compliance with applicable law
• Provide accurate information when creating your account
• Keep your API keys confidential and not share them with unauthorized parties
• Not attempt to circumvent rate limits or usage restrictions
• Not use the Service to process content that infringes third-party intellectual property rights
• Not reverse engineer, decompile, or attempt to extract the source code of the Service

4. Customer Content and Sole Responsibility

You are solely responsible for all content you submit to the Service (“Customer Content”). By submitting content, you represent and warrant that:

• You own the content or have the necessary rights and permissions to process it
• The content does not violate any applicable law or regulation
• The content does not infringe any third-party intellectual property, privacy, or other rights
• The content does not constitute illegal material of any kind, including but not limited to child sexual abuse material (CSAM), terrorist content, or content inciting violence

Klart AI acts as a content processor only and does not review or approve Customer Content before processing. We reserve the right to suspend or terminate access immediately and without notice if we become aware of any submission of illegal content, and to report such content to relevant law enforcement authorities. You agree to indemnify and hold harmless Klart AI from any claims, damages, or liabilities arising from your Customer Content.

5. Abuse Reporting and Takedown

OpenCorpo maintains a fingerprint registry that enables verification of signed content. If you believe content in our registry is illegal or violates these Terms, you may submit a takedown request to hello@opencorpo.com with the subject line “Takedown Request.” Include the verification URL or asset identifier and a description of the alleged violation. We will review and respond within 5 business days. Verified illegal content will be removed from our registry promptly and, where required by law, reported to competent authorities.

The C2PA provenance chain embedded in signed content records the customer account responsible for the submission. This information may be disclosed to law enforcement pursuant to a valid legal request.

6. API Usage and Fair Use

Your use of the API is subject to the limits of your plan (as described on the pricing page). We reserve the right to throttle or suspend API access if usage patterns suggest abuse, automated scraping, or attempts to circumvent metering. Overages beyond your plan limits are billed at the rates listed on our pricing page.

7. Payment Terms

Paid plans are billed monthly or annually via Stripe. Subscriptions auto-renew unless cancelled before the renewal date. Downgrades take effect at the end of the current billing period. Upgrades take effect immediately and are prorated. Refunds are not provided for partial months. All prices are in Euros and exclude applicable taxes (including VAT where applicable).

8. Data Processing

By using the Service, you grant us a limited license to process the images you submit solely for the purpose of providing the Service (signing, watermarking, fingerprinting). Images are processed in AWS Frankfurt (EU-WEST-1) and are deleted from our systems after the retention period applicable to your plan. A perceptual hash of each image is retained in our registry indefinitely for verification purposes. For details on data processing, see our Privacy Policy and, for business customers, our Data Processing Agreement.

9. Intellectual Property

You retain all rights to the content you submit to the Service. We claim no ownership over your images or the signed outputs. You are responsible for ensuring you have the right to process the images you submit. The Service technology, software, and platform remain the property of Klart AI.

10. Disclaimer of Warranties

The Service is provided “as is” and “as available.” We do not warrant that the Service will be uninterrupted, error-free, or that the compliance implementation will satisfy all regulatory requirements in all jurisdictions. The Service is a technical tool — you remain responsible for your own regulatory compliance. We recommend consulting qualified legal counsel.

11. Limitation of Liability

To the maximum extent permitted by applicable law, Klart AI shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or goodwill, arising from your use of or inability to use the Service. Our total aggregate liability shall not exceed the amount you paid us in the 12 months preceding the claim.

12. Termination

You may terminate your account at any time by cancelling via the dashboard or contacting support. We may suspend or terminate your access if you violate these Terms or engage in conduct harmful to other users or to the Service. Upon termination, your access to the API ceases immediately. Data is handled according to the retention policy applicable to your plan.

13. Governing Law

These Terms are governed by French law. Any disputes arising from or relating to these Terms or the Service shall be subject to the exclusive jurisdiction of the courts of Paris, France.

14. Changes to Terms

We may update these Terms from time to time. We will notify you of material changes by email or in-app notification. Continued use of the Service after the effective date of changes constitutes acceptance of the updated Terms.
