The parental monitoring software industry generated over $1.5 billion in revenue in 2023, according to a Grand View Research report. Bark, Qustodio, Covenant Eyes, Circle — the products promise the same thing: peace of mind through visibility. Know what your child is doing online, and you can keep them safe.
The evidence that this works as advertised is considerably more complicated.
What Monitoring Software Actually Monitors
Most parental control applications do some combination of the following: log texts and social media messages, flag keywords associated with concerning content, track location, limit access to certain sites or apps, and report device usage patterns to parents.
What they cannot monitor: conversations that happen in person, content shared and deleted before any report is generated, activity on devices the parent doesn't control, communications on platforms not included in their coverage, and the emotional and psychological experience of the child using any of it.
More fundamentally: monitoring software monitors behavior. It does not monitor the reasoning, relationships, and internal states that produce that behavior. A teenager who is considering something risky is not primarily going to be deterred by the knowledge that their texts are being scanned. They're going to be deterred — or not — by what they actually believe, who they trust, and what they think the consequences are.
The Research on Monitoring
Studies on the effectiveness of parental monitoring produce consistent findings that complicate the intuitive appeal of surveillance tools.
A 2016 study published in the Journal of Adolescence found that high levels of parental monitoring were associated with lower trust from adolescents and, counterintuitively, higher rates of risky behavior in contexts where monitoring was absent. The hypothesis that emerged: monitoring teaches concealment rather than caution. Children who are heavily monitored don't necessarily develop more judgment — they develop more sophisticated hiding.
A separate body of research on adolescent disclosure — why teenagers tell their parents things — consistently finds that the strongest predictor of voluntary disclosure is not monitoring, but relationship quality. Teenagers who describe their parents as warm, responsive, and non-punitive share significantly more about their lives than teenagers whose parents use monitoring strategies, regardless of how sophisticated those strategies are.
The distinction between knowing and understanding is crucial here. A parent with access to their child's messages knows what was said. They almost never understand the context, the relationship dynamics, or the emotional state that produced it. And acting on that surveillance data — confronting a teenager about something learned through monitoring — typically produces defensive withdrawal rather than connection.
What Presence Does That Monitoring Doesn't
Presence is the ability to notice, without instrumentation, that something is different. The parent who knows their child well enough to say "you seem off today" has information that no monitoring app can produce. The parent who has maintained consistent, non-transactional conversation over years has a channel that no VPN can circumvent.
Presence operates through relationship. Relationship operates through time spent together without an agenda, through demonstrated interest in the child's actual world, through being the kind of person a child believes will respond usefully rather than reactively when something goes wrong.
A teenager who has experienced their parent as emotionally safe — not as someone who never had rules, but as someone who engaged with complexity, acknowledged their own mistakes, and didn't catastrophize — is making a continuous, low-level calculation about whether to bring things to that parent. Every experience of being heard rather than managed improves the odds.
The Appropriate Role of Tools
This is not a case against all digital structure. For young children — under eight or nine — content filtering makes developmental sense, because they genuinely lack the capacity to evaluate much of what they might encounter. Location sharing with the agreement of an older teenager, used for safety and not surveillance, is different from covert monitoring. Agreed-upon usage patterns are different from secretly installed tracking software.
The distinction worth drawing is between tools that supplement a relationship and tools that substitute for one. A parent who uses monitoring software instead of conversations has outsourced the thing that actually matters. A parent who uses agreed-upon structures within a relationship of trust has simply built some scaffolding.
The scaffolding is not the building.
The Question Worth Asking
Before installing monitoring software, a parent might usefully ask: what would have to be true about my relationship with my child for them to come to me when something goes wrong?
If the honest answer is "I'm not sure they would," that's the problem worth solving. Monitoring software doesn't solve it. It documents the consequences while the conditions that produced them remain intact.
The relationship is the safety system. Everything else is downstream of that.
