How it works
Restkin does three things, in this order: it captures a record, it reminds you before it lapses, and it lets the right trusted person find it when they need it. Here's what each step actually feels like.
Step 01 — Capture
Snap a passport, insurance card, or vehicle title. Restkin extracts expiry dates, document numbers, and the issuing authority — all on your device, before encryption. You confirm the fields, then the record is sealed. No file ever leaves your phone as plaintext.
Step 02 — Renew
Lead times are matched to the document — 9 months for a passport, 60 days for an insurance policy. The reminder is a guided workflow, not a notification: prep checklist, link to the official portal, deadline countdown. You always submit yourself; we prepare, you decide.

Step 03 — Share
Invite a spouse, parent, or advisor by email. Grant access category-by-category. They never see what they don't need. Every view is logged to you. Revoke anytime. If something happens to you, the time-lock or veto-based release opens the door without you having to be there.

What we see vs. what you see
Every row of data in your vault has a user-side view and a server-side view. The server-side column is shorter than the user-side column. By design.

The first record
The first action should be low risk: one passport, one reminder, one trust proof. Restkin meets you there, then grows with you.
