Set it up once. It keeps itself current.
-
Bring your people in.
Import from your iPhone, Google, Outlook, a CSV, or a vCard file. Tether spots the duplicates as it goes and shows you what it found before it merges anything. Only the contacts you pick are saved to your account — the rest of your address book is never stored.
-
Check your circles.
You start with Family, Friends, Community, Professional and Holiday Cards already there, and Tether suggests who belongs in each — so this is approving a few suggestions, not building a filing system. Each circle decides what those people see about you. There is a floor everyone gets — your name, photo, and mobile — and you build up from there.
-
Connect.
If someone already has you in their contacts and you have them in yours, you connect automatically. Otherwise, send them a link or let them scan your code — they will get a request, and nothing happens until one of you accepts.
-
Stop maintaining it.
From then on, their details come from them and yours go to them. When someone moves, changes jobs, or gets a new number, it is already right on your phone.

What Tether never does
- Post anything on your behalf
- Message your contacts for you
- Pre-select people to invite
- Sell your data
- Show you ads
