Trust Relay keeps a quiet map of where your accounts and policies live, and who to tell — so the people you love aren't left guessing if something happens to you. So much of what a family needs to know lives only in one person's head. Trust Relay helps you write it down once: the institutions where your accounts are held, the people who should be contacted, and the guidance you'd want passed along. Then it waits, quietly, in the background — for years, if needed — until your family is the one who needs it. What you can do • Build a private map of your institutions — banks, insurance, retirement, and more. Search by name; account numbers are optional. • Name the people who should be told, and write guidance for each in your own words. • Add an optional personal message, delivered only to the person you name. • Confirm you're OK with a single tap when it's time to check in. • Reach our team any time through in-app support. What we never do • We never ask for passwords, PINs, private keys, or login credentials. • We never sell your information. • We're not a will and not a substitute for one — a companion to your legal documents, never a replacement. When the time comes, your information is shared with the people you named only after a careful verification process — never automatically. Trust Relay is a record-keeping service, not a law firm, bank, or insurer, and does not provide legal, financial, or tax advice. For wills, trusts, and beneficiary designations, please consult a qualified professional. Membership is $4.99/month or $49.99/year. Payment is charged to your Apple Account at confirmation of purchase. Membership renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel anytime in your Apple Account settings. Trust Relay is available in 148 countries and regions.
