Questions
How do contacts update themselves?
Once you are connected with someone, you are not keeping a copy of their details — you are reading theirs. When they change a number or move, your phone has the new version. It works the same way in the other direction, so changing yours once reaches everyone you are connected to. Inside the iPhone's own Contacts app, this happens through Tether+ contact sync, which you set up once.
What can other people see about me?
Only what you have granted the circle they are in. Everyone you connect with sees a floor — your name, photo, handle, and mobile — and you build up from there per circle. Open anyone and tap How they see you to see your own card exactly as they see it, plus a count of what is hidden.
Do I need everyone I know to join?
No. Tether works on day one as your own address book, and events work for people who are not on Tether at all — they RSVP from a link with no account.
Does Tether read or sell my contacts?
No. Only the contacts you pick are saved to your account; the rest of your address book is never stored. We do not sell personal data, run ads, or use ad-tech trackers. Nothing is ever sent to your contacts on your behalf.
Why do you need a real mobile number?
To text you a sign-in code, and because a verified number is what makes the mutual-contact match trustworthy. It is never used to let other people look you up — that runs on a salted one-way hash.
How do I delete my account and my data?
Settings, then Delete account. You can export everything first as CSV, JSON, or vCard. Deletion removes your data.
