What Contact Backup & Transfer's label means for you
Contact Backup & Transfer's App Store page shows “No Details Provided”. Apple requires a privacy label when a developer submits an update, so this usually means the app has not been updated since labels became mandatory in December 2020, or the developer has not completed the form. It does not mean the app collects nothing, and it does not mean it collects everything: it means there is no statement to hold the developer to.
Until a label appears, your iPhone's permission prompts are the most reliable signal. Every time Contact Backup & Transfer asks for photos, location, contacts, the microphone or tracking, you can say no and see whether the feature you need still works.
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.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.
Settings to check for Contact Backup & Transfer

Does Contact Backup & Transfer track you?
Without a label there is no tracking statement to rely on. You can still refuse tracking at the iOS prompt.
Lock Contact Backup & Transfer behind Face ID
- Find Contact Backup & Transfer on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Contact Backup & Transfer now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Contact Backup & Transfer has a passcode of its own. It does not change what the app sends to its developer.

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 Contact Backup & Transfer 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.
