Why sync your contacts?
Nimbus only keeps your people current if it’s connected to where your contacts already live. Connect your accounts once — Nimbus pulls everyone in for review, then keeps them current for you automatically, in the background, both directions.
Connect all three and you get one address book that’s always right — on your phone, in your email, everywhere. Miss one and part of your contacts keep going stale.
Google / Gmail — connect once; Nimbus pulls your contacts in for review, then pushes updates back so your Gmail address book stays current on its own. Step by step →
Outlook / Microsoft — the same one-click connect, in and out. Step by step →
iPhone / Apple (iCloud) — Apple needs a one-time app-specific password. The sync screen walks you through it, step by step. Step by step →
Nothing is saved or sent until you approve it — you review every batch first. Only contact info goes out, never your notes, relationship levels, or anything private.
