Phone numbers change. People move. Instead of chasing updates, share one link — friends, family, and colleagues fill in their own details, and you approve every update before it touches your address book.
Step 1
Send everyone the same link.
Text it, email it, or drop it in the group chat. Nobody installs anything.
One link does all the work. You never copy details out of a text message again.
Share your link
Everyone gets the same personal link — text it, email it, or drop it in the group chat. No app for them to install, no account for them to create.
They update themselves
People fill in their own details — new number, new address, new email — right from their phone, in under a minute.
You stay in control
Nothing changes silently. Updates wait in a review queue; approve them with one tap and your address book is current.
No follower counts, no "social graph" — just an address book that stays accurate with almost no effort from you.
Works fully offline
Your whole address book lives on your device. Read it on a plane, edit it in a dead zone — it syncs itself when you're back online.
Lists and mailing labels
Group people into lists — holiday cards, the team, the family — and print mailing labels straight from the app.
You approve every change
Incoming updates land in an approval queue. If you and a contact change the same field, you pick which version wins — field by field.
Birthdays, remembered
A birthday calendar built straight from your contacts, so the next one is always in sight — even offline.
No passwords
Sign in with a passkey or an email link. There's no password to forget — or to leak.
Yours to keep
Import from vCard; export to CSV or vCard anytime. No lock-in — it's your data, and it leaves with you.
Getting started takes about a minute. Your contacts do the rest.
