Terms of Service | ConceptViz – Générateur de diagrammes scientifiques IA pour enseignants et chercheurs

1. Acceptance of Terms

These Terms of Service (“Terms”) govern your access to ConceptViz (“the Service”), an AI-powered tool that helps educators create projector-ready diagrams for STEM lessons. By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use ConceptViz.

2. Service Description

ConceptViz lets you describe a science or math concept in plain English and returns diagrams sized for slides, worksheets, and lab instructions.

4. Accounts & Security

You agree to provide accurate information, keep your credentials secure, and notify contact@conceptviz.app of any unauthorized access. You are responsible for all activity that occurs under your account.

5. Credits, Subscriptions & Billing

Free accounts receive a limited number of watermarked diagrams for evaluation.
Paid plans allocate diagram credits each billing cycle. Unused credits expire at the end of the cycle unless otherwise stated.
Subscriptions renew automatically until cancelled. Cancellation stops future charges but does not retroactively refund past payments.
Taxes or payment-processing fees may apply. All charges are in USD.

6. Acceptable Use

You may not:

Generate content that is unlawful, hateful, or unsafe for K-12 audiences
Upload prompts that include student personally identifiable information (PII)
Attempt to probe, reverse engineer, or bypass security features
Resell the Service, share logins, or provide diagrams to others as if they were generated manually
Misrepresent ConceptViz diagrams as human-drafted to win bids or pass off the Service as your own platform
Use the Service to create deceptive or fraudulent educational materials

We may monitor usage to ensure compliance.

7. Generated Content & Licensing

You retain rights to the diagrams you create, subject to the License & Commercial Use policy.
Only active paid subscribers may use diagrams commercially (selling curriculum, marketing services, district deployments, etc.).
ConceptViz does not train its internal models on your prompts or images, but we may store logs long enough to troubleshoot abuse or quality issues.
You are responsible for reviewing diagrams before showing them to students and for ensuring they do not infringe third-party rights.

8. Classroom & Commercial Use

Classroom use covers non-commercial teaching activities with your own students. Commercial use includes selling digital resources, publishing textbooks, marketing tutoring businesses, or distributing diagrams beyond your class. Free accounts are restricted to classroom evaluation only.

9. Payments, Refunds & Cancellations

Billing is handled by trusted payment processors. Refund eligibility is defined in our Refund Policy. To cancel, visit your billing portal or email contact@conceptviz.app before the next renewal date.

10. Service Availability & Modifications

ConceptViz is provided “as is.” We may change features, impose limits, or discontinue parts of the Service without notice. We are not liable for downtime caused by maintenance, network providers, or third-party AI infrastructure.

11. Termination

We may suspend or terminate accounts that violate these Terms, abuse credits, or endanger students. You may terminate your account at any time; outstanding fees remain payable. Upon termination you lose access to stored diagrams on our servers.

12. Limitation of Liability

To the fullest extent permitted by law:

ConceptViz is not liable for indirect, incidental, or consequential damages.
Total liability for any claim is limited to fees you paid during the 12 months preceding the claim.
We are not responsible for decisions you make using generated diagrams (lab safety, medical instructions, etc.).

14. Changes to Terms

We may update these Terms from time to time. We will post the revised version with an updated “Last updated” date. Continued use of ConceptViz after changes take effect means you accept the new Terms.
