Key Takeaways

Many apps request permissions they don't technically need to function.
Granting broad access — like contacts or microphone — can expose data beyond your intent.
Both Android and iOS let you review and revoke individual app permissions at any time.
Denying a permission once does not permanently block an app from asking again.
Auditing permissions regularly is one of the most practical steps for everyday digital privacy.

Why Permissions Deserve More Than a Tap

When an app asks for access to your camera, location, or microphone, the on-screen prompt is easy to dismiss with a quick tap. But each "Allow" is a real decision with real consequences for your privacy. Permissions are the gateway between an app and your device's hardware and personal data — and app stores don't vet every permission request for necessity or proportionality.

The result: many apps hold access they rarely use, or access that has no clear relationship to what the app actually does. A flashlight app that wants your contacts, a game that wants your precise GPS location — these requests should prompt skepticism, not reflex taps.

This checklist helps you understand what each common permission actually enables and gives you a systematic way to review what's already been granted on your device. For a broader look at locking down your digital life, see our annual digital security audit checklist.

Denying a Permission Doesn't Delete Past Data

Revoking a permission stops an app from collecting new data going forward, but it does not delete data the app may have already gathered. If you're concerned about data an app collected before you revoked access, check the app's privacy policy or account settings for a data-deletion option. For apps that handled health or financial information, this step is especially worth taking.

What to Have Ready Before You Start

Before working through the checklist items, gather the tools you'll need and set aside uninterrupted time. The audit itself takes 15–30 minutes depending on how many apps you have installed.

Required

Your phone's Settings app

The primary place to view and revoke all app permissions — look for Privacy, Apps, or Permissions in the main settings menu.

Required

Privacy Dashboard (Android 12+)

Shows a timeline of which apps accessed sensitive permissions — camera, microphone, and location — over the past 24 hours.

Required

App Privacy Report (iOS 15+)

Displays how often each app has accessed permissions and which network domains apps have contacted.

Optional

A note-taking app or spreadsheet

Useful for logging which permissions you revoked per app, so you can reference your decisions later if an app stops working as expected.

Permissions Checklist: What to Audit and Why

Work through each group below. For every app listed under a permission, ask: Does this app's core function require this access? If the answer isn't clearly yes, revoke it and see whether the app still works for your purposes. You can always re-grant a permission later.

After you finish, take a few minutes to review privacy settings that often go unchecked — many defaults work hand-in-hand with app permissions.

Location Access

Review every app with "Always On" location access and change to "While Using" unless there is a clear, specific need for background tracking. Must
Remove location access entirely from apps where location has no clear function — such as productivity tools, utility apps, or games without navigation features. Must
Check whether any shopping, coupon, or retail apps have location enabled, as this data is commonly used for behavioral advertising. Should

Microphone Access

Identify all apps with microphone permission and confirm each has a voice, audio recording, or video-call feature you actually use. Must
Revoke microphone access from apps that have no audio function — games, e-commerce apps, or utilities rarely need it. Must
Check keyboard and input apps for microphone access, as some voice-to-text keyboards retain audio data. Should

Camera Access

Confirm that only apps with a documented photography, video, or scanning feature retain camera access. Must
Revoke camera access from any app that requested it at install but where you've never used a camera feature within the app. Must

Contacts Access

Audit which apps can read your full contacts list — this data often includes names, phone numbers, and email addresses of people who never agreed to share their information. Must
Revoke contacts access from any app where the social or communication feature is one you don't use. Must
Look specifically at apps you downloaded for a single use or promotion — these frequently retain contacts access after their initial purpose has passed. Should

Precise vs. Approximate Location

On devices that offer both options, switch apps from precise (GPS-level) to approximate location unless turn-by-turn navigation or geofencing is the core feature. Should
Note that weather apps typically need only approximate location — precise GPS coordinates are rarely necessary for a forecast. Nice to have

Background App Activity

Check which apps are permitted to run in the background and remove this capability from apps that don't require real-time updates (e.g., games, lifestyle apps). Should
Disable background refresh for any app that pairs with location or microphone access, as background activity can trigger data collection without your active use. Must

Health & Fitness Data

Review which apps have access to your Health or Fitness data store (Apple Health, Google Fit, etc.) and remove apps that have no fitness function. Must
Limit access to only the specific data categories an app needs — most platforms allow granular control (steps only, heart rate only, etc.). Should

Final Review Steps

After revoking permissions, open each affected app and confirm it still performs its core function — this catches cases where a feature genuinely depends on the access. Must
Delete apps you no longer use rather than simply revoking permissions — uninstalling removes all associated data access entirely. Must
Schedule a recurring reminder (quarterly works for most people) to repeat this audit as new apps are added and existing apps update. Nice to have

After the Audit: Habits That Stick

A one-time audit is useful, but permissions accumulate over time as you install new apps. Build a short review into your routine — even once per season takes under ten minutes once you know where to look.

A few principles worth keeping in mind going forward:

  • Choose "While Using" over "Always" whenever location access is offered as an option. This restricts background tracking without breaking the feature.
  • Question new permission prompts when an app update triggers them. Developers sometimes add data-collection features in updates; a new permission request after months of silence is worth scrutinizing.
  • Consider the sensitivity of the data type. Microphone and camera access carry different risks than, say, access to your step count. Prioritize reviewing those first.

If you use wellness or mental health apps, note that they may request access to sensitive health data. Our article on the tradeoffs of self-help apps for mental wellness covers what to consider before sharing personal data with those tools. Similarly, if you're building out a smart home, permissions extend beyond your phone — see our guide on questions to ask before buying a smart home device.
