Every report your family has collected, in one vault only you can open.
Privexa gathers lab reports, prescriptions, scans, and wearable readings from anywhere they came from. Read across them with a medical model hosted in India, and learn what has changed in plain Hindi or English.
Good evening, Aarav
Up eighteen points since November. Rakshak wrote 3 questions for your next visit.
Only you keep the record. Everyone else gets the complete context.
Your reports sit in a plastic folder at home, in three different lab portals, in a WhatsApp thread with your sister, and across different hospital EMRs. Every new doctor starts from scratch, and you are forced to recite your medical history from memory in a brief ten-minute consultation.
The record was always yours. It was just never in one place, and never in your custody.
Adding a report takes about as long as forwarding a message.
Forward the PDF the lab emailed you, photograph the physical printout your father brought home, or connect Health Connect and let readings sync automatically. Privexa extracts the clinical values and indexes them cleanly.
- Universal Parser. Messy scanned receipts and crisp digital PDFs both resolve into clean biomarker charts.
- Multi-Profile Partitioning. Track records for yourself, parents, and children within one vault without data mixing.
- Uncompromising Privacy. Client-side encryption ensures no human or machine reads your file unpermitted.
Family Vault
Rakshak reads the whole longitudinal file, not only today's page.
Rakshak is Sanskrit for the guardian. Built on MedGemma and hosted on sovereign Indian infrastructure, it interprets trends across years of test results and synthesizes clear questions for your physician.
- Longitudinal Awareness. It interprets whether a number is an anomaly or a chronic trajectory.
- Never Hallucinates Citations. Every claim cites the exact lab date and test origin.
- Bilingual Fluency. Responds naturally in clear English or conversational Hindi.
Rakshak Clinical Co-Pilot
- Should our LDL target be lowered below 70 mg/dL?
- Is lifestyle management sufficient, or are statins indicated?
- When should we repeat an ApoB / Lipid panel?
A daily health check, even without a smartwatch.
Rest your fingertip on the camera lens for 45 seconds to derive photoplethysmography (PPG) metrics entirely on-device. If you use a wearable, Health Connect unifies the streams into one coherent morning baseline.
- Actionable Focus. One recovery score and one sentence instead of dozens of conflicting notification badges.
- On-Device Processing. Camera signals are analyzed locally and discarded immediately.
Your recovery is steady. Heart rate variability is 8ms above your 30-day baseline and sleep held at 7 hours. Today is primed for high-effort physical output.
Enterprise-grade security, patient-level ownership
Healthcare records demand absolute confidentiality. Privexa is architected on zero-trust principles so that not even our engineers can read your files.
Client-Side Keys
Decryption keys are generated in your smartphone's Secure Enclave. What leaves your phone is ciphertext.
DPDP Act Aligned
Built strictly for India's Digital Personal Data Protection Act. Full consent traceability with instant revocation.
Indian Sovereignty
All object storage and AI inference nodes run on MeitY-empaneled data centers inside Indian borders.
ABDM Interoperable
Compatible with India's Ayushman Bharat Digital Mission (ABDM) standards for seamless health ID linking.
Zero vendor lock-in. Your records are yours to take.
A health vault you cannot leave is a walled garden. We believe you should always own your historical data in universally readable formats without having to file a support ticket.
- 1-Click Complete Export. Download your entire longitudinal history at any time as an organized ZIP archive.
- Standard Formats. Receive original lab PDFs alongside standardized FHIR/JSON structured exports.
- Permanent Portability. Share your archive with any hospital, doctor, or alternative platform instantly.
Where your records live, and where they never go.
Privexa was built around a singular principle: you are the only human with authorization to open your vault.
Encrypted before network transmission
Keys are created locally in your device's keystore. Nothing unencrypted ever hits the wire.
Direct identifiers stripped
Names, phone numbers, and addresses are masked before Rakshak analyzes the clinical values.
Erasure-coded distributed storage
Encrypted shards sit across Indian infrastructure with no single database vulnerability.
Nothing in your vault is ever monetized or provided to commercial entities without explicit, auditable opt-in permission.
PRIV: Rewarding healthy record-keeping habits
Each periodic check-in, uploaded scan, and family record earns PRIV utility tokens inside the application. Use them across our expanding network of accredited lab partners and pharmacies.
"I uploaded 4 years of disparate blood tests on a Sunday afternoon. In minutes, Rakshak organized an intelligible trendline, giving my father's cardiologist context they had never seen before."

Common questions on security and medical accuracy
Need more technical details? Write to our engineering leads at security@privexa.io.
Can doctors or insurance companies access my files?
Only if you explicitly generate a time-limited share link. Links expire within 72 hours by default, can be revoked at any second, and log every IP access event.
How does Rakshak prevent AI medical hallucinations?
Rakshak uses strict retrieval-augmented generation (RAG) mapped solely to your uploaded documents. It is programmed to state when data is missing rather than extrapolate, and flags all source lab documents directly in the response.
What occurs if I switch devices or uninstall the app?
Because files are encrypted on your phone, you are given a 12-word zero-knowledge recovery seed upon vault creation. This allows you to restore your vault seamlessly on a new device.
Which diagnostic chains are supported?
We are working on adding more diagnostic centers. Meanwhile, you can add PDF from any lab or testing center.

Real-world health cohorts from India, governed by provenance.
Privexa originates and governs tiered longitudinal patient datasets across India, empowering medical AI and life science teams to license de-identified cohorts with verifiable consent or ethical waivers.
Archives include longitudinal imaging studies with paired radiology reports spanning decades.
Data Provenance Envelope
Train on real longitudinal modalities within a Secure Enclave
We structure high-noise Indian clinical data into standardized FHIR bundles. Because radiology files carry high re-identification risks, foundation model teams compute securely inside Privexa's infrastructure rather than downloading raw files.
- Longitudinal Depth. Up to 15 years of uninterrupted patient trajectories.
- Paired Multimodal Data. DICOM imaging accompanied by expert radiologist evaluations.
- Secure Enclave Access. AI models are trained on our servers; raw DICOMs never leave our borders.
Type 2 Diabetes & Early CAD Cohort
Scale of the data layer
Our patient application and clinical partnerships continuously feed clean, longitudinal depth into the network.
How data flows from patient to researcher
Tiered pathways ensure strict adherence to DPDP Act regulations for both prospective and retrospective datasets.
Origination
Ingested via explicit patient app opt-ins or hospital EMR integration.
Standardization
Normalized to FHIR resources and OMOP Common Data Models.
PII Masking
Scrubbing of direct and indirect identifiers by Privexa acting as Data Processor.
Consent & Waivers
Ledgers carry proof of explicit consent or documented IEC waivers for historical cohorts.
Secure Enclave
Enterprise buyers compute on raw data entirely inside Privexa's controlled infrastructure.
Engineered for strict global and domestic compliance
India's DPDP Act and global clinical trial guidelines mandate transparent provenance. Privexa protects your research from regulatory liability.
Request Compliance Dossier- Tiered DPDP Compliance: Patient-consented prospective data and IEC-waived retrospective data managed squarely under DPDP Act Section 17(2)(b) research exemptions.
- Secure Enclave Inference: Buyers train models safely within Privexa's infrastructure, mitigating the risk of AI facial reconstruction from DICOM downloads.
- Indian Data Residency: Stored in Indian regions to fulfill statutory compliance and data localization mandates.
- Audit Trails: Immutable audit logs generated for every research cohort computation.
