Medical Data Sovereignty Architecture
In-App Encrypted Vault & Zero-Knowledge Architecture
Unlike public web chatbots where sensitive clinical data can leak into model retraining pools, Boostara Medical AI enforces absolute client-side data sovereignty: all patient health records, diagnostic images, and clinical reports are stored and encrypted directly inside your local Boostara App Vault.

• Local Device Storage: Raw patient records and exported reports reside exclusively on the clinician's authenticated physical device.
• Controlled Ephemeral Processing: When cloud inference is requested, packets traverse a pinned TLS 1.3 encrypted tunnel into isolated volatile RAM. Zero hard-drive caching; memory is zeroized upon token stream completion.
• Zero Model Re-Training on PHI: Patient images are never aggregated or used to re-train public foundation models without explicit institutional research agreements.
