Kin is a working prototype. This page describes what’s actually true about how it handles your information today — it is not a substitute for a formal, lawyer-drafted Privacy Policy, which we’ll publish before a wider launch.
The information you or your family choose to enter — names, relationships, where documents and accounts are kept, care wishes, and similar planning details. We don’t buy data about you from anyone else.
In a hosted Postgres database (Supabase). A handful of the most sensitive fields — access notes, ballpark values, plan answers, care wishes — are encrypted before they’re written, so even direct database access can’t read them in plain text.
Only the family members you invite, scoped by the per-section permissions you set. We don’t show your data to anyone else, and we don’t sell it, rent it, or use it for advertising.
A shared link (to a Brief or a Summary) is a private, unguessable web address you control — you can revoke it at any time. Emails we send (invitations, notifications) go through a transactional email provider (Resend) and exist only to deliver that one message.
If you have questions about your data, or want a copy of it or want it deleted, write to preparewithkin@gmail.com. A person reads that inbox. Deletion is handled by hand today and confirmed back to you by email.
