Smartphone Privacy Checklist for Android and iOS

Smartphones are powerful tools that offer incredible convenience, but they also collect vast amounts of personal data. Taking proactive steps to protect your privacy on your Android or iOS device is crucial. This checklist provides actionable steps to minimize tracking and enhance your data security.

Apps request permissions to access various features and data on your phone. Regularly reviewing and restricting these permissions is essential. This overlaps with the principles outlined in Android Privacy: Permissions, Privacy Dashboard and Location Control.

Android:

• Privacy Dashboard: Go to Settings > Privacy > Privacy Dashboard. This provides a summary of which apps have accessed permissions like location, microphone, and camera.
• Permission Manager: Navigate to Settings > Privacy > Permission Manager. Here, you can granularly control permissions for each app and permission type. Revoke access where it isn't absolutely necessary.
• App-Specific Permissions: Go to Settings > Apps, select an app, and then tap "Permissions". Adjust permissions as needed.

iOS:

• Settings > Privacy & Security: This is your central hub for managing permissions.
• Review Individual Permissions: Tap on each permission type (Location Services, Contacts, Calendar, Photos, Microphone, Camera, etc.) and see which apps have access. Choose "While Using the App" or "Ask Not to Track" whenever possible, or deny access altogether.

Actionable Steps:

1. Be stingy with permissions. Only grant access if the app genuinely needs it for its core functionality.
2. Choose "While Using the App" for Location. Avoid "Always Allow" unless absolutely necessary.
3. Review permissions regularly. Apps may update and request new permissions.
4. Uninstall unnecessary apps. The fewer apps you have, the less data is being collected.

Location tracking is a significant privacy concern. Minimize the amount of location data your phone collects and shares.

Android:

• Location Services: Go to Settings > Location. You can toggle location services on or off entirely.
• App-Specific Location Permissions: Similar to the general permission audit, control which apps have access to your location and when. Choose "Allow only while using the app" or "Ask every time".
• Google Location History: Go to Settings > Location > Google Location Accuracy. Turn off "Improve Location Accuracy" to prevent your phone from using Wi-Fi and Bluetooth to improve location accuracy. Review and delete your Google Location History in your Google account settings.

iOS:

• Location Services: Go to Settings > Privacy & Security > Location Services. You can disable location services entirely, but this will impact functionality of some apps.
• App-Specific Location Permissions: As with Android, configure location permissions for each app. Choose "While Using the App", "Ask Next Time or When I Share," or "Never".
• Significant Locations: Go to Settings > Privacy & Security > Location Services > System Services > Significant Locations. Disable this feature to prevent your phone from tracking the places you frequently visit. Clear your history.

Actionable Steps:

1. Disable Location Services when not needed. Turn it on only when you require location-based services.
2. Choose "While Using the App" whenever possible.
3. Review and delete your location history regularly. Both Google and Apple maintain a history of your location.
4. Disable "Significant Locations" (iOS).

Apps often continue to operate in the background, consuming battery life and potentially collecting data. Control background activity to improve privacy and battery life.

Android:

• Battery Optimization: Go to Settings > Battery > Battery optimization. You can prevent apps from running in the background by selecting "Optimized" or "Restricted". Be mindful that this might impact app functionality.
• Data Saver: Go to Settings > Network & internet > Data Saver. This can limit background data usage, which can also improve privacy.

iOS:

• Background App Refresh: Go to Settings > General > Background App Refresh. You can disable it entirely, or selectively disable it for individual apps.

Actionable Steps:

1. Disable Background App Refresh (iOS) or use Battery Optimization (Android) for apps that don't need to run in the background.
2. Regularly close apps you're not actively using.

Advertising networks track your activity across apps and websites to create a profile for targeted advertising. Leverage the tracking controls offered by both Android and iOS.

Android:

• Advertising ID: Go to Settings > Privacy > Ads. Reset your Advertising ID periodically. This makes it harder for advertisers to track you across apps. You can also opt out of Ads Personalization, but this will likely just mean you see less relevant, not fewer, ads.
• App Tracking: Starting with Android 12, apps are required to request your permission to track you across apps and websites. Pay attention to these requests and deny them where possible.

iOS:

• App Tracking Transparency (ATT): Go to Settings > Privacy & Security > Tracking. Enable "Ask Apps Not to Track". Each app will now need to explicitly request your permission to track you across other apps and websites. Decline tracking requests.

Actionable Steps:

1. Enable "Ask Apps Not to Track" (iOS) or be diligent about denying tracking requests (Android).
2. Reset your Advertising ID periodically (Android).

Your web browser is a primary window into your online activity. Choosing a privacy-focused browser and using a VPN can significantly enhance your privacy.

• Privacy-Focused Browsers: Consider using browsers like DuckDuckGo, Brave, or Firefox Focus. These browsers prioritize privacy features like blocking trackers, disabling cookies, and preventing fingerprinting.
• VPN (Virtual Private Network): A VPN encrypts your internet traffic and masks your IP address, making it harder to track your online activity. Choose a reputable VPN provider with a clear no-logs policy.

Actionable Steps:

1. Switch to a privacy-focused browser.
2. Use a VPN, especially on public Wi-Fi networks.
3. Configure your browser's privacy settings to block trackers and third-party cookies.

Your Google and Apple accounts store significant amounts of data. Review and adjust your account-level privacy settings to control what data is collected and used. Refer to Privacy in the Google Ecosystem: Settings You Need to Enable or Privacy in the Apple Ecosystem: iOS, macOS and Apple Account for detailed instructions.

Actionable Steps:

1. Review your Google and Apple account privacy settings.
2. Disable activity tracking, ad personalization, and location history if you're comfortable with the trade-offs in functionality.
3. Use strong, unique passwords and enable two-factor authentication.

Before installing a new app, take a moment to review its privacy policy. Understand what data the app collects, how it uses that data, and with whom it shares that data. This ties in closely with Digital Hygiene: How to Minimize the Collection of Your Data.

Privacy threats and technologies are constantly evolving. Stay informed about the latest privacy news and best practices to protect yourself effectively. Topics like Using Artificial Intelligence Safely: Local Models and Confidential Modes become increasingly relevant as AI capabilities expand.

By implementing these steps, you can significantly reduce tracking and enhance your smartphone privacy on both Android and iOS devices.
