WebappApp: Put patients back in control of their medical records
WebappApp is a secure medical data ownership platform built on Stacks that empowers patients to own, control, and optionally monetize their anonymized health data—while preserving privacy, transparency, and auditability for researchers and providers.
Platform features designed for patient ownership
Patient-centric encrypted storage
Files are encrypted client-side; private keys remain with the patient. Off-chain encrypted storage is linked to concise on-chain references (hashes/NFTs) for verifiable proof-of-existence.
Granular access control
Grant, revoke, or delegate access at the file or field level using smart contracts. Role-based permissions let patients precisely manage who sees what and when.
On-chain audit trails
Every access request and permission update is immutably logged on Stacks, creating transparent, verifiable audit trails for patients and providers.
Opt-in research marketplace
Patients can anonymize datasets and approve researcher requests. Smart contracts enforce rewards or micropayments when approved data is used.
Emergency & delegate access
Set trusted delegates or emergency access rules that can be triggered with multi-sig or time-limited tokens—fully auditable and patient-approved.
Decentralized identity & BNS
Integrates with decentralized identity solutions and BNS for verifiable, privacy-preserving user identities without exposing raw personal info on-chain.
Our mission & story
We built WebappApp because healthcare data belongs to the person who lived it. Patients should be able to grant, track, and reclaim access—while preserving continuity of care and enabling ethical research.
Founded by privacy engineers and clinicians, WebappApp bridges secure, user-first encryption and verifiable blockchain records to create a platform where patients are the central authority of their medical narrative.
- Privacy-first: End-to-end encryption & client-side key control.
- Transparent: Immutable logs for accountability and auditability.
- Practical: Smooth integrations for providers, labs, and research partners.
How it works
- Patient uploads encrypted medical records via WebappApp client.
- Each record is hashed and registered on Stacks as a verifiable reference.
- Patient manages access with smart contracts. All reads are logged.
- Optionally opt into anonymized data sets for research with enforced payments.
Trusted by patients, researchers & clinics
"Finally I can decide who sees my records and for how long. The audit log gives me peace of mind—my medical history is mine."
"Access is fast and auditable. Patients share exactly what we need for care—no more silos, no more missing reports."
"Ethical, consent-first datasets are rare. WebappApp makes it possible to work with real-world data while compensating contributors fairly."
