🛡️ ON-DEVICE FAMILY HEALTH VAULT

What goes into your father's vault — and why.

When managing an aging parent, you are their informal care coordinator. During a 2 AM emergency or a new specialist appointment, having these 4 critical modalities organized offline on your phone is life-saving.

Why Store Clinical PDFs?Hospitals rarely communicate with each other. When visiting a new cardiologist or during an ER admission, having past stent discharge notes, NABL blood trends, and cashless pre-auth letters available offline prevents duplicate invasive tests and dangerous treatment delays.

Why is Personal Space free forever?

Health data is intensely personal. We believe you shouldn't have to enter a credit card just to check if an app respects your privacy. Once you trust Subra Space AI for yourself, you'll feel confident introducing it to your parents. That is how word-of-mouth grows organically.

ZERO-CLOUD PRIVACY ARCHITECTURE

Your health vitals belong to you. Not a cloud server.

Most health apps upload your sensitive biometric data to commercial clouds to monetize insights or train foundation models. Subra Space AI takes the opposite approach.

Zero Network Calls

100% Offline Capable

Subra Space AI operates completely without internet. Turn on Airplane mode and scan any monitor (OMRON, Accu-Chek, Braun, Beurer)—it extracts readings just as fast.

Hardware Keystore

AES-256 GCM Encryption

All health records, scanned photos, and audio notes are encrypted on disk using keys stored in your device's Secure Enclave.

On-Device Inference

Local Gemma 4 E2B AI

Our vision OCR model runs entirely on your phone's Neural Engine / GPU. Your photos are never streamed to any remote server.

Zero Cloud Database

SQLite with FTS5 Search

Instant search across years of medical notes, prescription changes, and vitals history powered by an embedded local SQLite engine.

Zero Tracking

No Account / No Telemetry

No email address or phone number required to use Personal Space. We include zero third-party advertising or analytics SDKs.

Unencrypted Export

You Own Your Raw Data

Export your complete database as standard JSON, CSV, or clinical PDF at any moment. Zero proprietary lock-in.

The Architecture Difference: Cloud vs On-Device

Everything you need to know about Subra Space AI

Common questions about on-device AI, medical device compatibility, and privacy.

Yes, 100%. When you point your camera at any blood pressure monitor (OMRON, Braun, Beurer, Citizen), glucometer (Accu-Chek, Contour, OneTouch), or thermometer, the vision recognition model (Gemma 4 E2B) runs directly inside your phone's processor. Zero bytes of image data, audio notes, or biometric values are ever sent over the internet.
