Key Takeaways

  • Apps that request permissions unrelated to their core function are a reliable warning sign.
  • Vague or hard-to-find privacy policies suggest an app has something to hide.
  • Excessive background activity can mean an app is collecting data you never approved.
  • You can audit installed apps right now using built-in phone settings on iOS and Android.

Why data mishandling is easy to miss

Most apps ask for your trust quietly. You tap "Accept," skip the privacy policy, and move on. The problem is that poor data practices rarely announce themselves. They hide inside dense legal text, ambiguous permission requests, and settings buried three menus deep.

The checklist below gives you a concrete way to audit any app on your device. It covers what to look for in permission requests, privacy policies, data-sharing behavior, and account controls. You do not need technical expertise to use it. What you need is a few minutes and the willingness to look closer than most people do.

For a broader picture of how to get your digital tools working for you rather than against you, see this guide to organising your digital life.

Permission requests

Check whether the app requests access to contacts, location, microphone, or camera when those features are not part of its core purpose. Must
Verify that location access is set to 'While Using' rather than 'Always' unless the app genuinely requires constant tracking. Must
Look for requests to access your photo library, call log, or SMS messages if the app has no obvious reason to need them. Must
Check whether the app asks for permissions during onboarding before you have done anything that would require them. Should

Privacy policy review

Confirm the app has a privacy policy at all; absence of one is a red flag, especially for apps that collect any account information. Must
Read the data-sharing section and check whether it lists specific third-party categories or uses blanket language like 'trusted partners.' Must
Check whether the policy explains how long the app retains your data and what happens to it when you delete your account. Should
Look for a clear contact method for data-related requests, such as a deletion or access request process. Should
Note whether the policy has a 'last updated' date; policies that have not changed in several years may not reflect current app behavior. Nice to have

Background activity and data collection

Open your phone's battery or activity settings and check whether the app shows high background usage relative to how often you actually open it. Must
Review the app's network activity if your phone or router provides that data; unexpectedly large data transfers when you are not using the app deserve investigation. Should
Check whether the app continues to request location data in the background after you have restricted it to 'While Using' in settings. Must

Account and data controls

Verify the app provides a way to export or download the data it holds on you. Should
Confirm the app offers a full account deletion option, not just a deactivation or hide-profile function. Must
Check whether deleting the account explicitly states that your data is removed from the company's servers, not just hidden from the interface. Must
Look for an opt-out option for data sharing with advertisers or analytics providers, separate from the general account settings. Should
Review the app's notification permissions: excessive or unrelated alerts can indicate the app is using push notifications as an engagement-tracking mechanism. Nice to have
Test whether the app functions at reduced capability when you deny optional permissions, or whether it refuses to work at all. Should

What to do when you spot a red flag

Finding one warning sign does not automatically mean an app is malicious. Some apps have poor defaults but allow you to tighten them. Others have opaque policies because their legal teams wrote for compliance rather than clarity. Context matters.

That said, a pattern of red flags is a different situation. If an app fails on permissions, policy transparency, and data-sharing controls at the same time, the reasonable move is to delete it and find an alternative. Revoke its permissions first through your phone's settings so any residual background access stops immediately.

Revoking permissions does not delete collected data

Turning off an app's permissions in your phone settings stops future collection but does not remove data the app has already gathered. To request deletion of stored data, you need to use the in-app account deletion process or submit a data deletion request directly to the company. Check the privacy policy for the specific process required.

Battery drain and background activity connect here too. Apps that run constantly in the background to collect location or usage data are often the same ones draining your battery. Understanding why some apps drain your battery faster can help you identify which apps are active when they should not be.

One broader pattern worth noting: the same instinct that helps you spot a misleading app privacy claim also helps you evaluate other kinds of online information. Common pitfalls when reading health information online covers that same critical-reading skill in a different context.

Tools you will need

No third-party software is required to complete this checklist. The most useful tools are already on your phone.

Required

iOS Privacy settings (Settings > Privacy & Security)

Review and revoke per-app permissions for location, camera, microphone, contacts, and more.

Required

Android Permission Manager (Settings > Privacy > Permission Manager)

See which apps hold each type of permission and change access levels without uninstalling.

Required

iOS Battery usage panel (Settings > Battery)

Identify apps with high background activity that could indicate unauthorized data collection.

Required

Android Battery usage panel (Settings > Battery > Battery Usage)

Check which apps consume power in the background relative to their actual foreground use.

Optional

App store privacy labels (App Store or Google Play listing)

Get a developer-reported summary of what data the app collects and how it is linked to your identity.
