Reading the label

What Contacts Backup Share Sync Hub's label means for you

Contacts Backup Share Sync Hub's label has 2 types under “Data Used to Track You”, 2 types under “Data Linked to You”, 1 type under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.

Tracking is the declaration that most separates apps. It means identifiers, usage data from Contacts Backup Share Sync Hub can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.

None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.

Contacts backup apps upload your whole address book — other people's names, numbers and addresses, not just yours. Check where the backup is stored, whether it is encrypted, and how to delete it from the server.

Among the 126 contacts backup apps in our snapshot with a label, 33% declare tracking, 48% collect data linked to you and 33% say they collect nothing. Contacts Backup Share Sync Hub lists 3 data types, about the same as the average of 2.2 for this group.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

On your iPhone

Settings to check for Contacts Backup Share Sync Hub

  1. 1

    Tracking

  2. 2

    Lock the app

    On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.

iOS 18 and later

Lock Contacts Backup Share Sync Hub behind Face ID

  1. Find Contacts Backup Share Sync Hub on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Contacts Backup Share Sync Hub now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Contacts Backup Share Sync Hub has a passcode of its own. It does not change what the app sends to its developer.

Read with care

What the label cannot tell you

  • A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Contacts Backup Share Sync Hub sends.
  • It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
  • Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
  • Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
  • Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
