Foundational Models
We host pretrained foundation models operated within Microsoft's Azure AI Foundry environment. While such models may originate from third-party providers (OpenAI, Hugging Face, Meta, etc.), all processing occurs within Microsoft's secure Azure infrastructure.
AI Inference Data Use & Retention
Student and teacher interaction data provided to AI-enabled features is processed solely to generate requested outputs and is not used to train, fine-tune, or improve any large language model. Prompts and responses are processed in real time and are not retained or repurposed beyond the requested interaction.
Data Isolation & Control
Customer data processed through Lessi's platform remains within Lessi's Azure environment, and each customer's data is stored separately from that of other customers. Microsoft's Azure OpenAI Service does not share customer content with external model providers, and data is processed in a manner designed to prevent unauthorized access, cross-customer use, or secondary use beyond the requested service. All data is processed within the United States.
Encryption & Security Controls
Lessi encrypts all data both in transit (TLS/SSL) and at rest (AES-256). Keys are managed in Azure Key Vault, and network isolation is enforced via Azure Private Link. Lessi AI's access is governed by Azure Active Directory and role-based access control (RBAC).
Auditability & Traceability
Azure Monitor and built-in audit logs capture every access and modification event. Detailed traceability ensures accountability in data processing and supports FERPA's right to review and amend records.
Data Retention & Deletion
Lessi retains customer and student data only as necessary to provide its AI-powered educational tools and to comply with applicable legal or contractual requirements. Lessi supports customer-directed deletion or return of such data in accordance with applicable law and agreement terms.
Upon receipt of a request for deletion, Lessi will respond within ten (10) business days to confirm receipt of the request and, where applicable, provide information regarding the scope and timing of the deletion. If Lessi is unable to fulfill a deletion request in whole or in part due to legal requirements, technical limitations, or data retention obligations, Lessi will notify the requesting party of the reason and, where feasible, the anticipated timeline for completion or alternative disposition consistent with applicable law.
