Your data security and privacy are our highest priority. Prior Labs is built with enterprise-grade encryption, isolation, and security controls to ensure your data remains protected at every stage — from upload through inference. *** ## Data protection All data processed by the TabPFN API — including uploads via the `/tabpfn/*` endpoints and predictions — is handled using secure, compliant infrastructure. **Encryption** * All communication is encrypted in transit using **TLS 1.2+**. * Data stored on our servers is fully encrypted at rest. * Encryption keys are securely managed and rotated in line with industry best practices. **Access controls** * Services run on hardened cloud infrastructure with strict access control, audit logging, and network segmentation. * Authentication is enforced via **Bearer tokens** on every request. All internal systems follow the principle of least privilege. * Continuous monitoring ensures compliance with modern enterprise security standards. **Data isolation** * No data is shared between customers. Each uploaded dataset, fitted model, and prediction request is scoped to your account and processed in isolated environments. * Data from one user or organization is never accessible to another. *** ## Model privacy TabPFN foundation models are **never trained or fine-tuned on customer data**. All training is performed exclusively on synthetic data under controlled conditions — guaranteeing complete separation between customer data and model weights. *** ## Data retention * Uploaded data may be stored temporarily for reproducibility and caching. * You can opt out of storage or request data deletion at any time by [contacting us](mailto:hello@priorlabs.ai). * We retain only minimal metadata necessary for authentication, billing, and audit purposes. *** ## Enterprise deployments TabPFN is available through enterprise deployments including on-prem and VPC deployment on **AWS SageMaker** and **Azure AI Foundry**, giving you full control over where your data is processed. Deploy TabPFN in your Azure environment. Deploy TabPFN in your AWS environment. *** ## Contact For questions about data handling, security compliance, or enterprise policies, reach out to: [**hello@priorlabs.ai**](mailto:hello@priorlabs.ai)
