In the app
Scan. Vault. Ask.
No account required. No waiting for a server. Everything that follows is running on your phone.
01 · Scan
02 · Vault
Organized by how medicine actually works.
Records filed by body system, timeline, medications, and protocols. Browse, search, and edit offline. Your files are plain Markdown — readable forever with or without this app.
03 · Ask
"What are my current meds?"
Type or speak any question about your records. EmbedGemma searches your vault semantically and Gemma 4 answers from your own data — no cloud, no latency, no exposure.
See it in action
Scan a prescription. Get a structured record.
The desktop demo walks through scanning a real prescription, asking the AI about drug interactions, and reviewing the Health Vault. Everything you see runs on a $700 Android phone — no server involved.
The full picture
Six AI models. One phone. No internet required.
Architecture
Privacy is the design.
Every cloud health app has the same seam: a server you have to trust. We removed the seam. Gemma runs on your Snapdragon chip. Records are Markdown files on your own storage. There is no backend to breach — because there is no backend.
80% of health apps share data with third parties (BMJ, 2019). Health Passport collects nothing. Uninstall to delete everything.
