Portable
Export a readable JSON file. Import it in another copy of Timmy.

AI only when you ask
Manual logging never uploads. Analyze a photo sends one compressed copy after consent. Hermes chat may receive up to 20 confirmed text-only entries after you connect; photos and backend credentials never enter chat.
Data controls
Exports can contain sensitive health notes and photos. Store them somewhere you trust.
Health sources
The Bristol groupings and urgent-symptom copy are grounded in public clinical guidance.
