Surveillance by Design: How the Web Tracks You Without Asking

You probably think that the moment of consent online looks like a button. “Accept.” “Agree.” “Allow all.” We’ve all been trained to believe that online tracking only happens after we’ve clicked something; that if we didn’t say yes, it won’t happen.

That belief is comforting. It’s also wrong.

A growing number of online tracking happens without any meaningful consent at all. Not because you or me are careless, but because platforms and advertisers have deliberately built systems where tracking us is the default, dishonesty is a feature, and our autonomy is quietly eroded in the background. You didn’t agree to this, but it’s happening anyway.

Cookie banners are already a super flawed concept, but even they imply a semblance of a choice for each of us. What’s more troubling is how much tracking now occurs behind the scenes, extending beyond website cookies and cache.

Modern online platforms now increasingly rely on a complex mixture of techniques that don’t require you to click “accept” to start profiling you. Device fingerprinting, probabilistic tracking, server-side data collection, embedded third-party scripts, and SDKs inside mobile apps; all of these methods operate silently without you knowing otherwise. No pop-up. No explanation. No clear opt-out.

From the moment you load a website or open an app, your data starts flowing, including but not limited to your device type, screen size, OS, browser, and language settings, time zone information, your IP address, and your interaction patterns. On its own, these crumbs of data may seem harmless, but put together, they form a remarkably stable identifier that’s often more persistent than browser cookies ever were.

The uncomfortable truth is that even if you actively reject cookies, use private/incognito browsing modes, and regularly clear your browsing history and cookies, your data is still being tracked in ways you never explicitly agreed to.

This Isn’t Theoretical. It’s Already Happened.

If this all sounds abstract, it isn’t. Platforms have already been caught tracking users without meaningful consent, including in cases involving deeply sensitive data.

One of the clearest examples is the period-tracking app Flo. Despite publicly promising users that their reproductive health data would remain private, Flo was found to have shared user information with third parties like Meta and Google through embedded tracking software. 

This included data about menstrual cycles, pregnancy intentions, and sexual health; information users never knowingly agreed to share with advertisers. The U.S. Federal Trade Commission (FTC) took action against Flo in 2021, and subsequent lawsuits led to major settlements, underscoring that this data sharing happened without proper consent.

And, sadly, Flo isn’t an outlier. Investigations and complaints have shown that tracking SDKs embedded in mobile apps routinely transmit data to third parties the moment an app is opened,  before users can reasonably understand, let alone approve, what’s happening. In some cases, platforms have been accused of monitoring activity across unrelated apps and websites, quietly building behavioral profiles without disclosure.

These cases expose an uncomfortable reality: much of today’s tracking doesn’t fail because you made bad choices; it succeeds because your consent was never meaningfully part of the system in the first place.

When Tracking Becomes Infrastructure

What makes this especially alarming is that this behavior is no longer confined to a handful of bad actors. It’s embedded into the mainstream internet itself. News outlets, social platforms, productivity tools, health apps, streaming services, nearly every layer of the modern web participates in the same data-hungry ecosystem.

Tracking is no longer an optional add-on. It’s structural.

When tracking becomes infrastructure, accountability erodes by design. Responsibility is diffused across ad networks, analytics providers, data brokers, cloud services, and platform integrations. Each actor collects “just a little” data, each claims a legitimate purpose, and yet the combined outcome is a surveillance system far more invasive than any single company would publicly defend.

Platforms often justify this data collection under broad, reassuring labels like “analytics,” “security,” or “improving user experience.” These terms sound benign, even necessary. But in practice, the same data used to measure performance is also used to determine intent, predict behavior, and optimize engagement in ways that benefit platforms far more than users.

The line between functionality and surveillance has been blurred so much that it’s nearly invisible. Tools that were originally designed to prevent fraud or understand traffic patterns now feed machine-learning models that decide what content is promoted, what emotions are amplified, and what behaviors are rewarded. 

You’re expected to trust platforms to regulate themselves; to believe that the same companies financially incentivized to collect more data will also know when to stop. History suggests otherwise.

Self-regulation has consistently failed in industries where data equals power, and the internet is not an exception to the rule. Meaningful transparency is rare. Independent audits are limited. Enforcement often arrives years after harm has already been done. By the time regulators act, the infrastructure has already shifted, and the damage has been normalized.

The Cost to Autonomy and Online Freedom

The consequences extend far beyond advertising.

Tracking without consent creates a massive power imbalance. Platforms gain the ability to shape what users see, which voices are amplified, and which perspectives quietly disappear. They can influence behavior without transparency, accountability, or user awareness. Over time, this narrows choice, limits discovery, and transforms the internet from an open space into a managed environment optimized for prediction and profit.

On a societal level, surveillance-driven business models reward scale over ethics and normalize the idea that constant monitoring is the price of participation. They also generate enormous pools of personal data that are routinely breached, leaked, or misused, leaving users to deal with consequences long after platforms have moved on.

Perhaps most damaging of all is the cultural shift this creates. When people come to believe that tracking is inevitable, autonomy stops being something we expect and starts feeling like an unreasonable demand.

When You Assume, You Make An…

You know how the phrase ends, right? This current system of online tracking persists because it relies on your assumed resignation. It thrives best when people like you and I believe we have no real choice, that consent is only symbolic, and that our personal privacy is already lost. But the truth is simpler and more unsettling: we didn’t agree to this.

You didn’t agree to be tracked across apps, devices, and online platforms without understanding how it’s happening or why. You didn’t agree to have intimate data funneled into opaque systems beyond your control. And an internet that operates this way isn’t neutral; it’s exploitative by design.

Online freedom doesn’t vanish overnight. It erodes quietly, little by little, a few clicks of consent at a time, while pretending to actually require your permission. Whether that erosion of privacy and accountability continues depends on whether we’re willing to stop accepting a system that was never built to listen in the first place.
