PurpleDaisy: Architecting software thattranslates human physiologyinto clinical clarity.
PurpleDaisy crafts sovereign clinical instruments for iOS. Powered by deterministic on-device machine intelligence, we distill intricate multi-decade biomarker records into profound biological clarity. Zero intermediate cloud transmission. Absolute epistemic sovereignty over your health data.
Three companions. Complete privacy.
Every PurpleDaisy companion turns complex medical data into absolute clarity. We build precision tools to protect your most intimate asset.
Meridian
The sovereign personal health vault. Transforms fragmented paper diagnostics, Quest/Labcorp reports, and hospital EHR records into a longitudinal biological timeline. Scans multi-page clinical panels on-device with zero server transmission, synthesizing 500+ biomarkers and phenotypic biological age with mathematical precision.
Capabilities
Vela
Circadian telemetry and neuro-autonomic pattern synthesis engineered for clinical healthspan. Translates continuous multi-modal biometrics into actionable autonomic recovery states, operating under complete local cryptographic custody.
Lune
Zero-knowledge neuroendocrine and reproductive cycle telemetry. Architected with uncompromising cryptographic isolation to model subtle hormonal transitions across decades without commercial surveillance.
“Diagnostic laboratory telemetry constitutes an individual's most sacred biological manuscript. It belongs unconditionally to the individual: an unassailable personal asset that must never be bartered to data brokers, insurers, or centralized multi-tenant cloud vaults.”

Encryption
Your private sanctuary. Secured on your device.
Hardware-Rooted Cryptography
Patient records are encrypted using authenticated AES-256-GCM directly within the local sandbox. Cryptographic keys reside exclusively within the device's hardware Secure Enclave, precluding unauthorized plaintext extraction even under direct forensic access.
Deterministic On-Device Inference
Optical character recognition and biomarker tokenization execute strictly on the Apple Neural Engine via Core ML. Natural language and computer vision pipelines are contained entirely within the application binary, requiring zero network socket communication.
Clinical & Regulatory Alignment
Engineered in strict alignment with HIPAA Technical Safeguards (45 CFR § 164.312), GDPR Chapter III patient data rights, and zero-trust architectural frameworks to satisfy the highest institutional data governance standards.
Pure Sovereign Utility
Our revenue model is strictly aligned with direct software licensing. The codebase contains zero third-party telemetry libraries, advertising SDKs, or behavioral brokers. Diagnostic telemetry remains under absolute patient custody.
