Health data should remain under personal control
Lab results, genetic variants, lifestyle patterns, and personal health notes form an intimate record of a person's biology. The person represented by that record should control how it is stored, analyzed, exported, and shared.
Many digital health products centralize this record as a condition of convenience. Storage, analysis, and sharing controls then depend on the provider's infrastructure, policies, and account model.
Privacy by architecture
Privacy policies define how a company may handle data. Architecture determines where readable data exists, which systems participate in access, and what a service provider can technically process.
Catina combines clear policies with feature-specific technical controls. Supported health records are stored in an encrypted local Health Vault, and current sensitive AI bodies use a separately protected browser-to-enclave path.
Personalized insight across a complete health record
Health information becomes more useful when it is organized across time and context. Lab biomarkers, genetics, lifestyle, supplements, notes, and goals can provide a richer foundation for personalized insight than any single report in isolation.
Catina imports lab reports from any lab or country with multi-language support, accepts supported raw genetics files, tracks confirmed biomarkers over time, and connects them with personal context. This creates a structured health record designed for ongoing exploration.
The sensitive AI path protects request and response bodies between the browser and an attested Trusted Execution Environment. Training, retention, connectors, account metadata, and other service paths are documented separately so each boundary can be evaluated directly.
Local storage with private AI processing
Catina stores supported health records in an encrypted local Health Vault. Standard protection uses backend-assisted unlock. Extra Local Protection adds a separate passphrase-gated encryption layer.
Current sensitive AI request bodies are encrypted in the browser for an attested Trusted Execution Environment. The relay handles the operational metadata required for authentication, routing, limits, billing, and reliability. This architecture reduces readable health data in Catina's operational systems while keeping each remaining trust assumption explicit.
A future for health data sovereignty
Health data sovereignty means controlling how a personal health record is used. Catina supports that control through local storage, encrypted export and re-import, optional Extra Local Protection, and transparent processing boundaries.
The product is designed to make private health organization practical: import existing records, confirm structured values, follow changes, generate personalized insights, and retain a portable encrypted copy.
Catina is building a privacy-oriented foundation for understanding personal health data while keeping control of the record. Product feedback can be sent in the app or by email. Support messages and operational metadata use service paths separate from protected sensitive AI bodies.
