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.
Acute Coronary Syndrome, PTCA with Drug-Eluting Stent in LAD, discharge vitals, and MRD verification.
HbA1c 8.2% (uncontrolled), LDL 142 mg/dL (target < 55), Fasting Glucose 148, and Creatinine 1.2.
LVEF 56% normal systolic function, mild anterior wall hypokinesia, and Philips EPIQ CVx evaluation.
Senior Citizen Health Plan E-Card, ₹18L Sum Insured, and ₹3.25L Initial Cashless Hospital Sanction.
Formal cardiologist review: Brilinta 90, Ecosprin 75, Rosuvas F escalated for LDL, and S.O.S Sorbitrate.
Ask anything about your father's health. Answered locally, in seconds.
No more frantically flipping through 20-page hospital discharge summaries or squinting at crumpled paper slips. Subra Space AI connects directly to your father's encrypted vault to retrieve exact dosages, explain diagnostic observations, and prepare emergency summaries.
Subra Space AI organizes, searches, and explains the records, prescriptions, and device readings you have stored. It never offers medical diagnoses, modifies clinical treatment, or replaces your physician.
A report your doctor will actually thank you for.
No more crumpled slips of paper or forgotten morning logs. Subra Space AI aggregates all device scans into a clean, standardized clinical summary ready for WhatsApp, email, or in-clinic AirPrint.
Standardized morning/evening distribution and 7-day mean averages follow standard hypertension protocol (AHA/ESH guidelines). Saves your doctor 5+ minutes per consultation while reviewing your vitals.

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.
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.
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.
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.
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.
SQLite with FTS5 Search
Instant search across years of medical notes, prescription changes, and vitals history powered by an embedded local SQLite engine.
No Account / No Telemetry
No email address or phone number required to use Personal Space. We include zero third-party advertising or analytics SDKs.
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
Why running AI locally on your phone is the only true guarantee of health data privacy.
