App Safety Red Flags: Warning Signs Users Shouldn’t Ignore

getty

Thousands of new apps appear in app stores every year, and it’s getting harder to tell which ones are legitimate and which could put personal or business data at risk. A polished interface, strong rating or confident privacy claim can make an app look trustworthy, but those signals don’t always tell the full story.

Before downloading a new tool—or giving it access to sensitive information—it’s worth taking a closer look at what the app is asking for and who’s behind it. Members of Forbes Technology Council share red flags that can help users make smarter decisions about which apps deserve their trust.

Unnecessary Cloud Dependence

One red flag is silent dependency on the cloud. If a basic app like a calculator, scanner or notes tool stops working when offline, ask why. Some apps need connectivity, but simple tools should not always phone home. When an app cannot explain what leaves your device, its privacy claims deserve extra scrutiny. - Sibasis Padhi, Walmart Inc.

Long Gaps Between Updates

An overlooked red flag is “update silence.” If an app hasn’t shipped meaningful updates in months yet continues to expand features or claims strong security, it signals neglect or a façade. Secure apps evolve continuously. Stagnant release cycles often mean unpatched vulnerabilities, abandoned ownership or a product maintained only enough to keep harvesting data unnoticed. - Jagadish Gokavarapu, Wissen Infotech

Heavy Reliance On Third Parties

Risk increases when an application relies on multiple third-party SDKs, APIs, analytics tools or cloud services. Each integration effectively becomes another trusted party and another path for data to leave the application’s control. - Kostiantyn Gitko, Devox Software

Excessive Data Collection

Users should watch for apps that collect significantly more data than their functionality requires. Overcollection of personal information often indicates monetization through data sharing rather than delivering user value, creating unnecessary privacy and security risks. - Neelam Gupta, Avanade

A Hard-To-Find Delete Option

Stop reading the privacy policy. Test the delete button. Before you give an app meaningful data, find the option to delete your account. If it’s buried, broken or requires emailing support, they’re not built to let you leave. Apps designed for trust make leaving easy. Apps that are designed to monetize you make leaving hard. - Varun J. Vincent, FalconFirst AI

Privacy Claims Without Proof

Be wary of apps that make big privacy promises without showing how they operate. If there’s no clear explanation of what data is collected, how it’s used or who is accountable for protecting it, that’s a red flag. Trust comes from transparency and consistency, not just a “Privacy First” label in the description. - Vibhor Kapoor, AdRoll

Vague Privacy Commitments

Watch for vague data minimization claims without specifics like “We only collect what we need.” A trustworthy app names exactly what it collects, why and who sees it. If a privacy policy runs five pages but still doesn’t tell you whether your data is sold to third parties or shared with advertisers, that’s your answer. Ambiguity in privacy language is a strategy, not an oversight. - Shane O’Donnell, Centric Consulting

A Polished App With No Clear Owner

In a market full of lookalikes, the red flag is a polished interface paired with a thin company behind it. Slick UI is cheap now; real accountability isn’t. Before I trust an app with anything that matters, I look for a named team, a credible track record and a review history that looks earned rather than engineered. Interface quality is no longer a proxy for trust. - Anna Drobakha, Groupe SEB

No Clear Business Model

The lack of a visible business model is a red flag. If an app is free, has no ads and charges nothing, ask how it sustains itself. The answer is usually your data. Permissions tell you what an app can access—the monetization model tells you what they’re motivated to do with it. When there’s no clear revenue path, you’re not the customer. You’re the product. - Dan Haiem, AppMakers USA

Overly Broad OAuth Permissions

If an app asks for broad OAuth consent (especially tied to your corporate Entra ID) and it can’t clearly justify exactly why it needs that access, that’s a big red flag. A lot of “helpful” tools turn into shadow access because users grant permissions without IT oversight. - Robert Bobel, Cayosoft

Overhyped Privacy Promises

The loudest privacy claim is usually the reddest flag. Real privacy is quiet. It lives in the architecture, not in a banner shouting “Military-Grade Encryption.” As someone who builds these systems, I know there is no such thing as zero data. Ask one question instead: How does this free app make money? If you cannot answer that, you are not the customer. You are the inventory. - Sarah Choudhary, Ice Innovations

Permissions That Don’t Match The App’s Purpose

One major red flag is when an app requests excessive permissions unrelated to its core function. A flashlight app should not need access to your contacts, microphone, location or photos. Users should also be cautious of vague privacy policies, unclear data-sharing practices and apps with little transparency about who owns or operates them. - Anand Gupta, Wipro

Trust Claims Without Visible Follow-Through

Privacy should be demonstrated through actions, not marketing. When a company’s messaging focuses heavily on trust and safety but provides little transparency on how those claims are implemented, users should look more closely. - Benedetto Biondi, Folks Finance

Consent Settings That Are Already Switched On

Pay attention to apps that launch with a wall of toggles already switched on—notifications enabled, tracking allowed and data sharing active, all before you’ve even used the product. That’s not onboarding. It’s a land grab disguised as a setup. Trustworthy apps start quietly and let you turn things on as you see the value. If an app assumes consent before earning it, that’s your red flag. - Marc Fischer, Dogtown Media LLC

Misleading Or Manipulative Ads

One major red flag is when an app relies on deceptive or overly aggressive ads that mimic system alerts, fake warnings or misleading buttons. Apps using manipulative ad behavior often prioritize engagement and data harvesting over user trust and security. Poor advertising practices can quietly signal deeper issues around privacy, tracking and overall platform integrity. - Arun Goyal, Octal IT Solution LLP

Post-Installation Behavior Changes

In regulated industries, the download decision is the least important moment. The real risk is what an app does after installation—which third-party SDKs it phones home to, how its behavior changes after updates, and whether anyone in IT knows it’s running. Permissions tell you what an app can access. Network behavior tells you what it does. - Jenny Larsson, Intact Insurance Specialty Solutions

Few Independent Reviews

If there are no reviews and no comments that are obviously from a nonassociated source, do not trust the app in a work environment. Unless you have a relationship with the devs and want to beta test, you should wait until there are reputable reviews. There will always be lookalike apps, especially now in the age of AI. Their sole purpose is to market and have you download. Choose wisely. - WaiJe Coler, InfoTracer

Unexplained Data Usage Spikes

Unreasonable data usage can be a red flag. All modern operating systems let you see which application produces how much data. If an app produces an unexplainable amount of data, it might be time to dig deeper. - Kevin Korte, Univention

Anonymous Or Unverifiable Developers

Check whether a named, verifiable company stands behind the app. Anonymous developers and a lack of support history are bigger red flags than any permission request. A privacy policy is only as trustworthy as the organization behind it. If you cannot find who built it or who to call when something goes wrong, the privacy claims mean nothing. - Venkata Ramya Ganti, Oprox
