Apple says its built-in Call Screening processing happens on your iPhone and isn’t shared with Apple. That statement covers Apple’s screening feature—not every part of a phone call. Your carrier still provides the call service, and any enabled caller-ID app has its own data practices.
What Apple says about Call Screening privacy
Apple’s published statement is: “Call Screening processing occurs entirely on your device and isn’t shared with Apple.” The feature answers calls from unknown numbers, asks callers for their name and reason for calling, then shows you their response so you can decide what to do. (Apple Privacy Features)
This is a specific claim about Apple’s Call Screening processing. It does not establish what information your mobile carrier handles to route calls, or what a separate caller-identification app collects or shares.
How the iPhone’s unknown-caller options differ
In Settings, the Screen Unknown Callers options control what happens to calls from numbers that aren’t saved in your contacts. (Apple iPhone User Guide: Screen and block calls)

| Option | What happens |
|---|---|
| Ask Reason for Calling | The iPhone asks an unknown caller for more information before it rings. You can review the response and decide whether to answer. |
| Silence | Calls from unsaved numbers are sent to voicemail without ringing. |
| Never | Call screening is turned off. |
Apple also documents a separate filtering option that places missed calls and voicemails from unknown numbers in an Unknown Callers list. Carrier-identified potential spam or fraud calls can be silenced and sent to voicemail; that depends on the carrier’s identification.
What the privacy statement does—and doesn’t—cover
Apple’s built-in screening
Apple says the screening processing is on device and not shared with Apple. When a caller responds to the prompt, the iPhone presents that response to you. The statement is not a guarantee that no information related to a call is handled elsewhere.

Your mobile carrier
Your carrier provides ordinary call service and may identify calls as potential spam or fraud. Apple says standard calling and data rates may apply. Its support information does not specify what call metadata each carrier retains or processes, so Apple’s on-device statement cannot answer questions about a particular carrier’s privacy practices. (Apple Support: Detect and block spam phone calls)
Caller-identification apps
iPhone supports compatible apps that provide caller-identification information. That is separate from Apple’s built-in screening. Apple’s guide does not describe the data practices of a specific app; check the app provider’s current privacy policy if you enable one. (Apple iPhone User Guide: Screen and block calls)

Live Voicemail is related, but separate
Live Voicemail displays a live transcription as someone leaves a voicemail. Apple says Live Voicemail processing also occurs on device and isn’t shared with Apple. (Apple Privacy Features)
Voicemail availability can vary by carrier and country or region. Voicemail syncing is a separate matter: Phone & FaceTime voicemail syncing to iCloud is controlled by its own setting, rather than being answered by Apple’s statement about local Call Screening processing.

How to turn off call screening
- Open Settings.
- Tap Apps, then Phone.
- Under Screen Unknown Callers, select Never to turn screening off. Choose Silence instead if you want unsaved numbers sent to voicemail without ringing.
Labels and menu wording can vary by iOS version and locale. Apple’s user guide describes the options in its call-screening settings documentation.
When call screening may behave differently
- Roaming: Apple says calls are not screened while roaming, regardless of the selected setting.
- After an emergency call: Call screening turns off for 24 hours after you call emergency services.
- Older software: On software earlier than iOS 17, Apple says Live Voicemail must also be enabled for call screening.
- Carrier and region: Voicemail features and spam identification may depend on carrier and country or region. Standard calling and data rates may apply.
These are behaviors documented by Apple; they should not be read as guarantees about every carrier’s network or policies. (Apple iPhone User Guide; Apple Support)
