7. AI Grading Disclaimer

Ethyra uses AI to assist with grading. AI-generated grades and feedback are suggestions and should be reviewed by the teacher. Ethyra does not guarantee the accuracy of AI output. Teachers are ultimately responsible for all grades assigned.

8. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT GUARANTEE UNINTERRUPTED, SECURE, OR ERROR-FREE OPERATION OF THE SERVICE.

These Terms are governed by the laws of the State of Delaware. Any dispute shall first be attempted to be resolved through informal negotiation for at least 30 days.
