What Contacts Backup + Transfer's label means for you
Contacts 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 Contacts 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.
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.

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 + 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.
