🛡️ MyMedVault

MyMedVault is a personal document vault — a secure, private app to store, organise, and understand your important documents. Upload any PDF or photo of a document, and the app uses AI to extract the content, generate a plain-English summary, and organise it automatically.

It is not a medical advice app. It does not diagnose, treat, or recommend anything. It is a smart document organiser — like a digital filing cabinet with AI-powered reading capability.

🔐 Authentication & Biometric Lock

• Register with email and password. Passwords are never stored in plain text — hashed using bcrypt.
• Sessions use JWT tokens stored in Android's hardware-backed Keystore — inaccessible to other apps.
• The app locks automatically when minimised. Fingerprint or face recognition is required to reopen.
• If biometrics are not set up on the device, you'll see the option greyed out with instructions to enable it in device Settings.

📄 Document Upload

• Tap the + button on the home screen to upload.
• Choose from: Camera, Gallery, or Files.
• Multi-upload: select up to 10 files at once from gallery or file picker.
• Camera scan: shoot a document directly in the app — files over 10 MB are rejected with a clear error.
• Supported formats: PDF, JPG, PNG.
• Set a title, document type (Lab Report, Prescription, Invoice, Insurance, Imaging / X-Ray, Scan, Certificate, Other), and assign to a family member.
• Each document card shows a person name pill ("Self" or the family member’s name) so you always know whose record it is at a glance.
• Processing happens in the background — you’ll receive a push notification when the AI is done.
• Non-medical documents (receipts, certificates) are still accepted and flagged as "Non-Medical Document" in the AI summary.

🤖 AI Processing Pipeline

• Step 1 — OCR: Google Cloud Vision API extracts all text from your document image/PDF, with English language optimisation for accurate results.
• Step 2 — AI Summary: Google Gemini reads the extracted text and writes a plain-English summary including patient info, a structured table of test results (with reference ranges & status), imaging/scan findings, and prescription details with dosage and frequency.
• Step 3 — Categorisation: AI automatically assigns the document to a category (Lab, Prescription, Imaging, etc.).
• Step 4 — Record Extraction: Key data points are extracted as structured records (dates, values, names, dosages).
• Regenerate Insights: On any existing document, tap the ⋮ (overflow) menu → Regenerate Insights, or tap the inline button on the Insights tab. A spinner shows progress and you’ll see a success or error message.
• Wide tables (e.g. full lab panels) are horizontally scrollable on small screens.
• If old documents don't have a category, tap "Re-analyze Documents" on the empty category filter state.

🗂️ Document Management

• Home screen shows all documents as cards with thumbnail, title, date, category badge, and a person name pill showing who the document belongs to.
• Category filter chips (top of list) — tap to filter by Lab, Prescription, Imaging, Invoice, Insurance, Other. Tap the filter icon for a multi-select filter sheet to combine categories.
• Family switcher (top bar chips) — switch between "Mine" and each family member's documents.
• Search (magnifier icon) — searches across all AI-extracted text content, not just titles.
• Tap any search result to go directly to that document's detail page.
• Delete a document from the detail page — permanently removes the file, extracted records, and AI data instantly.

👨‍👩‍👧 Family Profiles

• Tap the account icon (top-right) → Add Family Member.
• Enter name and relation (Spouse, Parent, Child, Sibling, Grandparent, Other).
• During document upload, choose which family member the document belongs to.
• Switch between family members using the chips below the search bar on the home screen.

💉 Vaccination Reminders

• Access via ⋮ menu → Vaccination Reminders on the home screen.
• Contains a full WHO/India schedule with 16 standard doses — BCG, Hepatitis B, OPV, DPT, Hib, Rotavirus, PCV, IPV, Measles, MMR, Varicella, and more.
• Each vaccine shows the recommended age (e.g. at birth, 6 weeks, 9 months, 5 years).
• Tap any vaccine to set a local push notification reminder for the due date.
• Reminders work for all age groups — both children and adults (booster doses).
• Reminder data is stored locally on your device and never sent to our servers.
