Discounts for Data: The Deal Hidden in App Permissions

The 28-year-old accountant from Chuka is not alone. Millions of Kenyans tap through “app permissions” daily, granting access to their contacts, cameras, microphone, location, photos, and browsing habits without a second thought. "I just want to use the app," Wanjiru says with a laugh. "Who has time to read all those pages?", she added.

But those unread terms hide a thriving industry. While she hunted for bargains, the app hunted for something far more valuable: her data. Free apps are not really free. They simply charge in a different currency. Instead of shillings, users pay with information about their lives.

Every time someone opens a food delivery app, it notes their location. When they browse products, it tracks their preferences and browsing behaviour. When they chat with friends, it learns their social circles.

This data becomes a detailed profile: from where you live, what you buy, when you shop, who you know and what you search for at any time.

Tech companies sell this information to advertisers. It is a lucrative trade. A single user's data might fetch just a few cents, but multiply that by millions and the numbers grow enormous.

Moses Kimani, a software developer in Meru, explains how it works. "These apps need to make money somehow," he says. "Since users won't pay upfront, they pay by simply becoming the product."

The business model is simple. Offer a useful service for free. Collect vast amounts of user data. Package and sell it to companies desperate to reach specific audiences.

Aloha Dario discovered this reality by accident. The teacher from Kisumu was shopping online when he noticed something odd, an advertisement appeared for the exact dress she had just viewed on another website. "It followed me everywhere," she recalls. "Facebook, Instagram, even YouTube. The same blue dress."

She felt unsettled. Someone was watching her digital footsteps. This is targeted advertising in action. Companies build detailed profiles to show users products they are most likely to buy. The system is eerily accurate.

A man searches for baby clothes once. Suddenly his social media fills with diaper advertisements and parenting advice. A woman googles "diabetes symptoms" and pharmaceutical ads flood her feed.

The technology tracks users across multiple platforms. That game app shares data with that news app. The fitness tracker talks to the shopping site. Everything connects.

John Mwangi runs a small electronics shop in Eldoret. He pays for targeted ads and sees the power firsthand. "I can reach people within five kilometres of my shop who searched for laptops in the last week," he says. "It's incredibly effective."

Yet free apps have genuinely transformed daily life. M-Pesa revolutionized banking for millions. WhatsApp connects families across continents at no cost.

These services have democratized access to tools once reserved for the wealthy. A farmer in Nakuru can check weather forecasts. A student in North Eastern can access learning materials. A trader in Nairobi can manage inventory remotely  from her phone. "I could not run my business without these apps," says Faith Njeri, who sells clothes online. "They have opened opportunities I never imagined."

The benefits are real and significant. But so are the hidden costs.

Some times the system malfunctions with serious consequences. Personal information leaks. Profiles get hacked, and ends up in the wrong hands.

Peter Omondi learnt this lesson painfully. The banker from Nairobi found his phone number on a spam list after using several free apps. Now he receives dozens of unwanted calls daily. "They sell your number to anyone," he says with frustration. "I get calls about loans I never applied for, products I do not need."

More concerning are the psychological effects. Apps designed to be addictive track how long users stay engaged. They learn which notifications work best. They discover the perfect moment to grab attention.

Dr Sarah Kamau, a psychologist in Nairobi, sees the impact in her practice. "These apps are designed to keep you scrolling," she explains. "They use your data to understand what hooks you, then they exploit it."

Young people are particularly vulnerable. Their entire social lives exist on platforms that harvest their every interaction. The real concern is not just what data companies collect, but how little users understand about the exchange.

Most Kenyans do not realise that when they download a free fitness app, they might be sharing their health information with insurance companies. When they use a free game, their children's data might be collected.

The permissions requested often seem harmless. Why does a flashlight app need access to contacts? Why does a game need location services? The reasons are rarely explained clearly. "Companies bury the important stuff in legal jargon," says Diana, the developer. "They know people will not read it."

Some apps collect data even when not in use. They track location in the background. They access microphones and cameras. They monitor every key stroke.The solution is not to abandon free apps entirely. That would mean losing valuable tools and connections. But rather users need awareness.

Technology experts suggest simple steps. Read permissions carefully before granting them. Use privacy settings. Delete apps that request unnecessary access. Check which companies have your data.

Some apps now offer privacy-focused alternatives. They charge a small fee instead of harvesting data. Others allow users to opt out of certain tracking.

Regulation is slowly catching up. Some countries now require clearer privacy policies and give users more control. But enforcement remains weak.

As Wanjiru shops on her discount app, she is beginning to ask questions. "I never thought about where my information goes," she admits. "Maybe I should."

The hidden cost of free apps is not hidden anymore. It is printed in those unread terms and conditions often referred to as “T&Cs”, embedded in those thoughtlessly granted permissions, reflected in those eerily accurate advertisements.

The question is whether knowing the price changes anything. Or whether convenience will always outweigh privacy in the digital marketplace where everyone is both customer and commodity.
