Email support@tiewell.app with what you were doing, what happened, and your iPhone model and iOS version. Screenshots help.
Do I need an account? Yes. Sign in with Apple, with Google, or with a one-time code emailed to you. Your records belong to that account, which is what keeps your iPhone and the Tiewell web app in step. If two people sign in on the same iPhone, each sees only their own records.
I signed out and my people disappeared. That is intended — records belong to the account. Sign back in and they are all there.
Where is my data? On your device, so the app works offline, and in your own account on our EU-hosted backend so your other device can read it. See the Privacy Policy.
Import shows only one contact. iOS asked you to choose contacts (limited access). Tap the orange banner on the import screen to share more, or in iOS Settings › Tiewell › Contacts choose Full Access.
