A pillar privacy checklist for reviewing iPhone and Android app permissions, including location, camera, microphone, photos, contacts, and background access.
Last checked: May 19, 2026. iPhone and Android settings labels can vary by version, region, and manufacturer. Use this as a review checklist, then follow the exact labels on your device.
Quick answer
Review app permissions every month, especially location, camera, microphone, photos, contacts, calendar, notifications, Bluetooth, nearby devices, files, and background access. Remove apps you no longer use and downgrade permissions that do not match the app's purpose.
Most people do not need to become privacy experts. They need a repeatable habit: open permissions, check the sensitive categories, remove unnecessary access, and uninstall apps that ask for too much.
Why permissions matter
Apps may need permissions to work. A camera app needs camera access. A ride-hailing app needs location. A messaging app may need contacts if you want contact discovery.
The problem is permission creep. An app may keep access long after you stop using a feature. Some apps also ask for permissions that are not clearly connected to their purpose. The more access apps have, the more data can be collected, leaked, misused, or exposed if the app account is compromised.
Monthly permission checklist
- Delete apps you no longer use.
- Review location access.
- Review camera and microphone access.
- Limit photo access where possible.
- Remove contact access from apps that do not need it.
- Check notification permissions.
- Review Bluetooth and nearby-device access.
- Check files, storage, and document access.
- Turn off background activity for apps you do not trust.
- Update apps from official stores.

Permission risk table
| Permission | Higher-risk use | Safer setting |
|---|---|---|
| Location | Always-on tracking for apps that do not need it | While using, approximate location, or deny |
| Camera | Utility apps asking without clear reason | Allow only when needed |
| Microphone | Games, wallpapers, or tools with no audio feature | Deny unless obvious |
| Photos | Full library access for a single upload | Limited selected photos |
| Contacts | Shopping or entertainment apps asking for address book | Deny unless contact discovery is needed |
| Notifications | Spammy apps pushing links or urgency | Disable or quiet notifications |
| Background activity | Apps running when not in use | Restrict if not needed |
The safest setting is the one that matches the feature you actually use.
Location settings
Location is one of the most sensitive permissions because it can reveal home, work, school, travel, religious visits, medical visits, and daily patterns.
Prefer "while using the app" instead of "always" unless the feature clearly needs background location. Maps, delivery, ride-hailing, weather, and fitness apps may need location for core features. Many games, shopping apps, calculators, and wallpaper apps do not.
If your phone offers approximate location, use it for apps that only need city-level information.
Camera and microphone
Camera and microphone permissions should be easy to justify. Video calls, voice notes, camera apps, and scanning apps need them. A basic flashlight, wallpaper, coupon, or calculator app usually does not.
Modern phones may show an indicator when camera or microphone is active. Treat unexpected indicators seriously. Close the app, check permissions, and uninstall suspicious apps.
Photos and files
Many apps do not need your full photo library. If your device lets you share selected photos only, use that option for apps where full access is unnecessary.
Be careful with apps that ask for broad file access. Documents, downloads, screenshots, and photos may contain private data, IDs, invoices, school work, or work files.
Contacts and social discovery
Contact access can expose other people's information, not just yours. Before granting it, ask whether the feature is worth uploading your address book.
Messaging and social apps may use contacts to find friends. Many shopping, editing, entertainment, and utility apps do not need it.
Notifications can become a scam channel
Notifications seem harmless, but they can push fake urgency, phishing-style links, or manipulative sales messages. Disable notifications from apps that use fear, countdowns, fake account alerts, or repeated promotions.
For banking, email, password managers, and security apps, keep important alerts enabled.
Review permissions after major changes
Do a fresh permission review after buying a new phone, restoring from backup, giving a phone to a family member, adding a work profile, or installing many apps at once. Restored phones can bring old permissions back into your daily setup.
Parents should also review permissions on children's devices. A game or editing app that seems harmless can still request location, microphone, photos, or contact access.
What to do with risky apps
If an app's permissions do not match its purpose, remove the permission or uninstall the app. Choose better-known alternatives from official stores. Check recent reviews, developer name, update history, and whether the app has a clear privacy policy.
Do not install apps from links in random messages unless you can verify the source.
FAQ
Should I deny every permission?
No. Deny unnecessary permissions. Some permissions are needed for core features. The goal is matching access to purpose.
Are iPhone apps safer than Android apps?
Both platforms have privacy controls and risks. Safety depends on the app, permissions, updates, account security, and where you install apps from.
How often should I review permissions?
Monthly is a good habit. Also review permissions after installing many apps, changing phones, or seeing unusual battery, data, camera, or microphone activity.
