Apple positions iPhone as the privacy-friendly smartphone alternative to Android. While Apple's practices are genuinely better than Google's in several areas, meaningful privacy still requires active configuration.
App Tracking Transparency (ATT)
Settings > Privacy & Security > Tracking
This is Apple's most impactful privacy feature. Toggle off Allow Apps to Request to Track to prevent apps from asking to track you across other companies' apps and websites. For apps that have already been granted permission, you can revoke them here individually.
Location Services
Settings > Privacy & Security > Location Services
Set each app to While Using (never Always unless specifically needed). For apps that have no location function, set to Never.
Disable Precise Location for apps that only need approximate location (weather, local news).
At the bottom, disable Share My Location if you do not use Find My with family members.
Siri and Search
Settings > Siri & Search
For each app, disable Show in Search and Show Suggestions if you do not want Apple indexing your in-app content.
Settings > Privacy & Security > Analytics & Improvements Disable Share iPhone Analytics, Share iCloud Analytics, Improve Siri & Dictation, and Share with App Developers.
Personalized Ads
Settings > Privacy & Security > Apple Advertising Disable Personalized Ads. This limits Apple's ad network from using your data for targeting.
Face ID and Passcode
Settings > Face ID & Passcode Review what Face ID unlocks. Disable USB Accessories if you want to prevent USB devices from accessing your phone when it is locked.
Photos and Contacts
Settings > Privacy & Security > Photos / Contacts Review which apps have access to your photos and contacts. Revoke access from apps that have no legitimate need.
For Photos: Set permissions to Selected Photos rather than All Photos where possible.
Safari Privacy Settings
Settings > Safari
Enable Prevent Cross-Site Tracking and Hide IP Address from Trackers. Enable Privacy Preserving Ad Measurement. Disable Allow Websites to Check for Apple Pay if you are not using Apple Pay. Enable Fraudulent Website Warning.
iCloud Settings
Settings > [Your Name] > iCloud Review which apps sync to iCloud. Disable sync for apps where cloud storage of that data is not necessary.
Mail Privacy Protection
Settings > Mail > Privacy Protection Enable Protect Mail Activity. This prevents email senders from knowing when you opened an email (email tracking pixel protection) and hides your IP address from senders.
Using Temp90 on iPhone
For app registrations on iPhone, open Safari, navigate to Temp90, generate your temporary address, and use the iOS copy-paste feature to place it in the app's email field. The workflow is covered in our mobile Temp90 guide.
Frequently Asked Questions
Is iPhone genuinely more private than Android?
In default configuration, yes. Apple's App Tracking Transparency, on-device processing for many features, and business model (hardware sales rather than advertising) result in meaningfully less data collection than Google's Android defaults. With active configuration, both can be made significantly more private.
Does Apple access my iCloud Photos?
Apple scans iCloud Photos for CSAM (child sexual abuse material) and may scan for other policy violations. If this is a concern, disable iCloud Photos and store photos locally or in an end-to-end encrypted service.
How does Mail Privacy Protection work?
When you receive an email, Mail Privacy Protection downloads the email's remote content (including tracking pixels) in the background through a privacy relay, masking your IP and preventing the sender from knowing when you opened the email.
Conclusion
Apple's privacy architecture provides a better starting point than Android, but it still requires active configuration. App Tracking Transparency, location controls, analytics opt-outs, and Safari privacy settings are the highest-impact changes. Combined with using Temp90 for app registrations, these settings create a meaningfully more private iPhone experience.
