What are harvester apps, anyway?

Ever downloaded a work app, or maybe a simple game, and wondered why it’s asking for so much information? A harvester app is just that—an app that collects data you willingly share, but goes further by accessing more than it should. It’s like inviting a plumber into your house, only to find out they’re searching through your filing cabinets too.

For instance, the fitness app Strava was caught collecting and sharing user location data, even when the app wasn’t in use. Imagine if your work apps were doing the same, tracking more than they need and exposing sensitive business data.

Why should you care?

At first glance, you might think, “it’s just my location or contacts, why does it matter?” Here’s why it’s a big deal—it’s  not only your data at risk. Harvester apps can endanger your privacy and your company’s security.

Data Overload = Security Risk: The more data an app collects, whether personal or work-related, the greater the risk if that information is leaked or hacked. This could include everything from your location to your work emails and client contacts.

Corporate Risk: Employees using harvester apps on the same mobile device they use to access company resources–like email–can expose sensitive information, such as client data or internal communications. A seemingly harmless app could be collecting details about where employees go, who they meet with, and when.

Data Exposure: When an app collects a large amount of data, it opens the door for colluding apps to step in. Even if one app doesn’t have direct access to sensitive information, it can work with another app—like a harvester app—to exploit and share the collected data, making these apps even more dangerous when combined.

How to protect yourself (and your company)

Don’t worry—you don’t have to ditch all your apps or panic about every download. Here’s what you can do to protect your personal and work data:

  1. Check Permissions—seriously: Take the time to review what permissions apps are asking for. If a work app requests access to things it shouldn’t need, think twice before granting it.
  2. Regular app checkups: Make a habit of reviewing apps you’ve installed. If there are apps—especially work-related ones—that you don’t use anymore, uninstall them. Apps that sit unused can still collect data.
  3. Use mobile security tools: If you’re managing company devices, invest in a solution like Q-scout. It will identify apps that overreach and protect your sensitive business data from unwanted access.
