A private family health record
Sehat is one always-current record a family keeps together for their aging parents, medications, allergies, conditions, doctors, synced from the hospital and reviewed by the family. The emergency card is the product. Everything else exists to keep it accurate.
Invite-only. One family at a time. No public sign-up exists.
Allergies
Medications
Conditions
What medications, at what doses? What allergies? Who is their cardiologist? What insurance? In that moment, nobody remembers everything, and the sibling who knows may be asleep three time zones away. Sehat keeps one answer to all of it, maintained by the siblings together, and hands it over as a high-contrast screen for ER staff or a clean PDF, in one tap.
Data comes from the hospital, not from typing. Each parent connects their MyChart once, and Sehat syncs medications, allergies, conditions, immunizations, and results every day. But nothing synced is ever trusted automatically:
Synced items arrive as pending, one decision per screen: add it, dismiss it, or merge it with something the family already knows. Only what a person explicitly approves ever reaches the emergency card.
The kids
Siblings share the full record for both parents: the review queue for synced data, appointments with visit-note debriefs, a doctors directory, a documents vault, and a change feed where every edit is attributed and visible to everyone.
The parents
Each parent sees their own record only, in large, calm type. No edit controls anywhere, one button asks the family to update something. Medications lead with a plain sentence a person wrote:
“1 pill, morning, with food.”
Every medical value is AES-256-GCM encrypted before it touches the database, through a column type the code cannot forget to use.
Every change records who, what, before, and after. The database role the app runs as has no permission to alter that history.
The emergency card is cached on the phone, encrypted with a device-held key. It renders in airplane mode and reads as noise on disk.
No analytics, no crash reporters, no third parties. Health data leaves the system only when someone chooses to share the card.
