Two-row family graph
Every relation has two rows — one from your point of view, one from theirs. Either side can revoke independently. The substrate enforces it; Shield surfaces it cleanly.

Consent, made explicit.
No surprises.
A health record is the most personal thing you can share. Shield makes every grant deliberate, scoped, and reversible — and writes each one to the same consent ledger the rest of the suite reads.
Scope by data class
Medical records, prescriptions, appointments, address — you choose what each relation can see. Granular consent, never all-or-nothing.
Phone-based invites
Add a family member by phone. They receive an invite, accept, and choose what they share back. No directories, no scraping contacts.
DPDP audit by default
Every cross-side access is logged to the substrate consent ledger. See who looked at what, when, and under which grant.
One consent ledger
Every view, on the record.
Shield doesn't keep a private list of who can see what. It reads and writes the suite-wide consent ledger — so a grant you make here is the same grant Sayuk Tend honours at the clinic, and you can revoke it from one place.
- Each access is logged with who, what, when, and the grant it ran under.
- Revoke a relation and the ledger closes every scope it carried.
- The same ledger powers Sayuk Tend at the reception desk.
