Why the Download Decision Deserves a Pause

App stores host millions of titles. Many are legitimate and useful; others collect far more data than their core function requires, and some are outright malicious. The problem is that the icon, description, and star rating on a store listing tell you almost nothing about what an app actually does once installed.

This checklist gives you a consistent process to run before tapping "Install" — whether you're adding a productivity tool, a game, a financial tracker, or anything in between. It applies equally to mobile apps on iOS and Android and to desktop software downloads. Running through it takes 10–20 minutes and can save you significant trouble later.

Once you've built your app library thoughtfully, the next challenge is keeping it tidy. Our guide on auditing the apps on your devices walks you through deciding what to keep, archive, or remove.

Developer & Source Verification

Confirm the app is downloaded from an official store (Apple App Store, Google Play, or the developer's verified website) rather than a third-party repository. Must
Search the developer's name to verify they have a legitimate web presence, published contact information, and a history of other released apps. Must
Check whether the developer name on the store listing exactly matches what you'd expect — typosquatting (e.g., "Gooogle") is a common tactic used by counterfeit apps. Must
Look up whether the developer has been associated with any reported security incidents or data breaches by running a quick web search. Should

Permissions Review

Open the permissions section in the store listing and list every permission the app requests — camera, microphone, location, contacts, storage, and so on. Must
Ask whether each requested permission is necessary for the app's stated purpose; a flashlight app requesting microphone access, for example, is a clear mismatch. Must
Note any permissions you are uncomfortable granting and check whether the app can function with those permissions denied after install. Should
On Android, check whether the app requests permissions classified as "dangerous" under Android's permission model (e.g., precise location, SMS read/write, call logs). Should

Privacy Policy & Data Practices

Locate the app's privacy policy link in the store listing and confirm one actually exists — absence of a policy is itself a warning sign. Must
Scan the policy for what categories of data are collected, how long data is retained, and whether data is sold or shared with third-party advertisers. Must
Check whether the policy describes a process for requesting data deletion, especially if you may use the app temporarily. Should
On Apple's App Store, review the "App Privacy" nutrition label to see a structured summary of data collection practices before reading the full policy. Nice to have

Reviews, Ratings & Update History

Read recent one- and two-star reviews, not just the overall rating — low-rated reviews frequently surface specific privacy, stability, or billing problems. Must
Check the date of the most recent app update; an app that hasn't been updated in over 12 months may lack current security patches. Should
Verify the total number of reviews is proportionate to the claimed install count — an app with 10 million installs and 50 reviews deserves scrutiny. Should
Search the app name alongside terms like "scam," "data leak," or "removed from store" to surface any external reporting. Should

Alternatives & Necessity Check

Determine whether the task this app performs is already handled by a built-in feature on your device, eliminating the need for a third-party install entirely. Should
If the app is free, identify its revenue model before downloading — advertising, in-app purchases, and data brokering are the most common, and each has different implications for your privacy. Should

Tools That Make This Process Easier

You don't need specialized software to complete this checklist — most checks rely on information already available in app stores, search engines, and the apps' own documentation. That said, a few resources make the process more efficient.

Required

App Store / Google Play listing page

Provides permissions list, privacy nutrition labels, developer information, and user reviews in one place.

Required

Web search engine

Used to research developer reputation, look up reported incidents, and find independent coverage of the app.

Optional

Exodus Privacy (Android)

A publicly accessible tool that analyzes Android APKs for trackers and permissions beyond what the store listing shows.

Required

App's official privacy policy URL

The authoritative document describing how the app collects, uses, and shares your personal data.

Beyond the install decision itself, understanding what you're agreeing to with free apps is worth your time. Our piece on the privacy trade-offs built into free apps explains how data collection, ad targeting, and profiling work in practice.

After installation, staying on top of updates is equally important — they carry security patches that protect against newly discovered vulnerabilities. See everything you need to know about app updates for a full breakdown of what happens when you update (and what's at risk when you don't).

Sideloading Apps Carries Elevated Risk

Installing apps from outside official stores — a practice called sideloading — bypasses the security review processes those stores apply, however imperfect those reviews may be. If you do sideload on Android, only use sources you can independently verify as legitimate, such as a well-known open-source project's official site. On iOS, sideloading outside of Apple's TestFlight program is significantly restricted for this reason.
