Introduction: Every Parent’s Dilemma with Teens
Your teenager spends hours on their phone, their bedroom door closed. You sometimes hear notifications late at night. When you ask what they’re doing, the answer is invariably: “Nothing” or “Stuff”. This opacity worries you. What if your child was a victim of cyberbullying? What if they were viewing dangerous content? What if they were talking to malicious strangers?
Faced with these legitimate concerns, the temptation to monitor your teenager without their knowledge is great. There’s no shortage of tools: surveillance apps, access to messages, geolocation, browsing history… Technically, it’s possible. But morally, psychologically and educationally, is it advisable?
This question divides families, child professionals and even legislators. On one side, parents’ duty to protect. On the other, the teenager’s right to privacy and the risks of damaging the trust relationship.
In this in-depth article, we’ll explore all facets of this debate, understand the psychological and relational issues, and offer you alternatives to spying that protect your teenagers while preserving your relationship with them.

Part 1: The State of Parental Surveillance in France
1.1 Revealing Statistics
According to a survey conducted by the Junior Connect Institute in 2024, 42% of French parents admit to having already checked their teenager’s phone without their knowledge. This figure rises to 58% among parents of teenagers aged 11 to 13.
Among the most common surveillance practices:
- Reading messages and conversations (38% of parents)
- Checking browsing history (45%)
- Monitoring social media (52%)
- Using geolocation apps (29%)
- Installing actual spyware (12%)
These figures reveal a paradox: we’re in an era where the dominant discourse promotes dialogue and trust, but actual practices show massive surveillance, often hidden.
1.2 The Legal Framework in France
Legally, the question is complex. In France, parents are responsible for their minor children and have a duty to protect them. Can this duty justify surveillance of their communications?
The Civil Code stipulates that parental authority is exercised in the child’s interest. Parents must protect their child’s safety, health and morality. This responsibility may legitimize certain forms of control.
However, the International Convention on the Rights of the Child (ratified by France) recognizes the child’s right to privacy. Article 16 states: “No child shall be subjected to arbitrary or unlawful interference with his or her privacy, family, home or correspondence.”
Case law tends to consider that parents can exercise control proportionate to the child’s age and identified risks, but that systematic and secret surveillance of a mature teenager may constitute a violation of their rights.
1.3 Available Tools on the Market
The parental surveillance app market is booming. Here are the main categories of available tools:
“Classic” parental controls: These apps allow content filtering, screen time limiting and blocking certain applications. The child usually knows they’re installed.
Geolocation apps: They allow real-time tracking of the teenager’s location. Some work transparently (the teenager voluntarily shares their location), others are more discreet.
Spyware: These tools, often sold as “advanced parental monitoring,” allow reading all messages, listening to calls, remotely activating the microphone, capturing screenshots… Their use on an adult without consent is illegal in France.
Password retrievers and account access: Some parents use tools to retrieve their children’s account credentials.

Part 2: Arguments in Favor of Surveillance
2.1 The Duty to Protect Against Real Dangers
Supporters of parental surveillance advance compelling arguments. The dangers teenagers face online are very real:
Cyberbullying: According to a study by the Ministry of National Education, 20% of middle school students report having been victims of cyberbullying. The consequences can be dramatic: academic disengagement, depression, and in the most serious cases, suicide attempts.
Exposure to pornography: The average age of first contact with online pornography is 11 years in France. Increasingly violent and degrading content is accessible in just a few clicks, with proven consequences on teenagers’ sexual development.
Online predators: Pedophile criminals massively use social media and online games to contact minors. Grooming techniques (gradual manipulation) are increasingly sophisticated.
Scams and phishing: Teenagers, less suspicious, are prime targets for online scammers.
Radicalization: Some extremist content specifically targets vulnerable teenagers.
Faced with these dangers, parents who monitor their children feel they’re exercising their protective responsibility. “I’d rather have an angry teen than a teen in danger,” sums up a mother interviewed in a survey.
2.2 Early Problem Detection
Surveillance can detect weak signals before a situation deteriorates:
- A teenager exchanging messages with an unknown adult
- Messages revealing bullying suffered or inflicted
- Concerning searches (suicide, anorexia, drugs…)
- A toxic romantic relationship
- Illegal activities (product resale, intimate photos…)
Several parent testimonials report having been able to intervene in time thanks to surveillance: a teenage girl planning to run away to meet someone encountered online, a boy victim of blackmail after sending intimate photos, a young girl whose searches revealed suicidal thoughts…
2.3 The Argument of Insufficient Maturity
Teenagers’ brains are still maturing. Neuroscience has shown that the prefrontal cortex, responsible for impulse control, consequence anticipation and decision-making, doesn’t reach full maturity until around age 25.
This brain immaturity explains why teenagers often take reckless risks, overestimate their ability to handle situations, and underestimate dangers. In this context, some parents feel that a certain degree of surveillance compensates for this neurological immaturity.

Part 3: Arguments Against Spying
3.1 The Destruction of Trust
The strongest argument against spying is its impact on the parent-teenager relationship. When a teenager discovers they’ve been monitored without their knowledge (and this almost always happens), the consequences are usually disastrous.
Psychologists specializing in adolescence report typical reactions:
- Deep sense of betrayal and privacy violation
- Intense anger, sometimes with acting out (running away, risky behaviors)
- Total loss of trust in parents
- Reinforcement of concealment behaviors
- Withdrawal and communication breakdown
“Trust is built over years and destroyed in seconds,” reminds Dr. Marie Duval, child psychiatrist. “A teenager who discovers their parents were spying on them may take years to rebuild a trust relationship, sometimes never completely.”
3.2 The Counter-Productive Effect on Safety
Paradoxically, spying can make the teenager less safe, not more. Here’s why:
Development of advanced concealment techniques: A teenager who knows or suspects they’re being monitored will learn to create secret spaces. Secondary accounts, hidden apps, phone borrowed from a friend, prepaid SIM… Parents lose all visibility on truly risky activities.
Communication breakdown: If the teenager no longer trusts their parents, they won’t come talk to them about problems. Yet, in real danger situations (cyberbullying, contact with a predator), communication is often the only effective means of intervention.
False sense of security: Parents who monitor may think they control everything. In reality, they only see what the teenager wants them to see.
3.3 Hindering the Development of Autonomy
Adolescence is a crucial period for developing autonomy and responsibility. Spying sends a clear message: “You’re not capable of managing alone, I don’t trust you.”
This message has consequences on psychological development:
- Difficulty developing confidence in one’s own judgment abilities
- Prolonged dependence on authority figures
- Problems constructing an autonomous identity
- Anxiety related to feeling constantly observed
Teenagers need private spaces to develop: experimenting with identities, having secrets, making small-scale mistakes, developing relationships outside parental view. Spying denies this fundamental need.
3.4 Ethical Questions
Beyond practical considerations, spying raises fundamental ethical questions:
What educational model are we transmitting? If we teach our children that monitoring someone without their knowledge is acceptable when we think we’re doing it for their own good, what are we teaching them about respecting others’ privacy?
Where do we draw the line? If spying is justified for teenagers, why not for young adults? For spouses? The logic of surveillance “for the other’s good” is a slippery slope.
What do we do with collected information? A parent who spies may discover intimate aspects of their teenager’s life (sexual orientation, first experiences, political opinions…) that they weren’t ready to share. This intrusion into intimacy can have profound psychological consequences.

Part 4: What the Experts Say
4.1 Psychologists’ Perspective
The vast majority of psychologists specializing in adolescence advise against spying, while acknowledging the legitimacy of parental concerns.
“Spying is an easy solution that avoids real educational work,” explains Dr. Philippe Jeammet, child psychiatrist and adolescence specialist. “The real challenge is building a relationship where the teenager can talk, where they know they’ll be heard without judgment. It’s much harder than installing software, but it’s the only approach that really works.”
Psychologists emphasize the importance of distinguishing control and protection. Control seeks to know and master. Protection seeks to accompany and prepare. The former creates dependence, the latter develops autonomy.
4.2 Institutional Recommendations
French and international institutions converge toward a nuanced position:
The Rights Defender recommends a progressive age-appropriate approach, with transparency about control tools used and increasing respect for privacy as the teenager grows.
CNIL reminds that even parents must respect certain principles of protecting their children’s personal data, particularly the principle of proportionality and prohibition of disproportionate surveillance.
WHO and UNICEF recommend media education and dialogue rather than surveillance, except in cases of proven danger.
4.3 Studies on Effectiveness
The rare comparative studies on the effectiveness of different parental approaches to screens show converging results:
- Approaches based on dialogue and accompaniment are associated with better digital behaviors in teenagers
- Approaches based on strict control and surveillance are associated with more hidden and circumvention behaviors
- The quality of the parent-teenager relationship is the best predictor of risky behaviors (or their absence)

Part 5: Alternatives to Spying
5.1 Transparency Rather Than Secrecy
If you feel some form of surveillance is necessary, transparency changes everything. A teenager who knows their parents can access their phone behaves differently from one who believes they’re being spied on without their knowledge.
Transparency allows:
- Maintaining relational trust
- Opening dialogue about reasons for this surveillance
- Negotiating terms and limits
- Establishing conditions to progressively reduce control
“I know you have access to my messages and I accept it because I understand your concerns” is a very different position from “I thought I had privacy and I discover everything was monitored”.
5.2 Media Education: Preventing Rather Than Monitoring
The best protection isn’t surveillance but education. A teenager educated about media knows how to recognize dangers and respond appropriately, even without surveillance.
This education must start well before adolescence and cover:
- Recognizing online manipulation attempts
- Scam and phishing mechanisms
- Grooming techniques used by predators
- Managing digital reputation
- Legal consequences of certain behaviors (sharing intimate images, cyberbullying…)
- Critical thinking about content
This is exactly the approach we offer at DYNSEO with our training “Screen Awareness: Understanding, Acting, Accompanying”. This training gives you tools to educate your children and teenagers about digital issues, progressively and adapted to their age.
5.3 Structured Dialogue About Digital Practices
Rather than monitoring secretly, establish regular dialogue moments about digital practices. These conversations should be:
Non-intrusive: It’s not an interrogation but an exchange. Also share your own practices and difficulties with screens.
Regular: A weekly ritual, for example, allows maintaining open dialogue without each conversation being perceived as an intrusion.
Focused on experiences rather than content: Rather than “What did you watch?”, ask “How do you feel after spending time on social media?”, “Has anything strange happened to you online recently?”.
Without judgment: If the teenager feels they’ll be judged or punished for what they say, they’ll stop talking.
5.4 Negotiated Usage Contracts
Establishing screen usage rules together creates a clear framework while respecting the teenager’s autonomy. A good usage contract for teenagers includes:
- Discussed and accepted time limits
- Rules about usage locations (not in bedroom at night, for example)
- Agreement on what can be shared online (photos, personal information…)
- Digital courtesy rules (no phone at the table…)
- Conditions and terms for contract revision
- What happens in case of non-compliance
The advantage of the contract is that it makes the teenager an actor in their own regulation rather than passive subject of external control.
5.5 Mediation Tools Rather Than Surveillance
Some tools promote dialogue rather than control:
Shared activity reports: Rather than spyware, some apps generate usage reports (time spent per app, sites visited…) that the teenager can view and share with parents. It’s a basis for discussion, not a surveillance tool.
Collaborative family apps: Apps allow defining rules and limits together, with a dashboard visible to everyone.
Breaks integrated into apps: Some educational apps, like COCO THINKS and COCO MOVES developed by DYNSEO, directly integrate regulation mechanisms. With its mandatory sports break every 15 minutes of play, this app prevents overconsumption without requiring external surveillance.

Part 6: Special Situations Where Increased Surveillance May Be Justified
6.1 Warning Signs That Change the Game
All of the above applies to “normal” situations. But certain warning signs may justify closer surveillance, even at the cost of temporary relational tension:
- Sudden behavioral changes (isolation, aggressiveness, sadness…)
- Sudden drop in academic performance
- Signs of substance use
- Self-harm or concerning discourse about death
- Concerning associations
- Signs of bullying suffered or inflicted
- Sexualized behaviors inappropriate for age
In these situations, protecting the teenager may temporarily take precedence over respecting their privacy. But even then, transparency remains preferable when possible.
6.2 Intervention in Case of Proven Danger
If you have concrete reasons to think your teenager is in immediate danger:
1. Intervene first, discuss later: Safety takes priority over method
2. Involve professionals if necessary: Psychologist, doctor, law enforcement depending on severity
3. Explain your approach: Even if the teenager is angry, explain why you acted this way
4. Accompany crisis exit: Emergency intervention must be followed by foundational work
6.3 Pre-existing Disorders
Some teenagers have particular vulnerabilities that may justify more intensive digital support:
- Autism spectrum disorders: Increased vulnerability to manipulation
- Attention disorders: Difficulty self-regulating screen time
- Anxiety or depressive disorders: Risk of vicious circle with certain content
- Eating disorders: Exposure to pro-anorexia content
In these cases, closer monitoring, in coordination with health professionals accompanying the teenager, may be appropriate.

Part 7: How to Progressively Accompany Toward Digital Autonomy
7.1 The Principle of Progressive Autonomy
The ultimate goal isn’t to control indefinitely, but to prepare the teenager to do without control. This implies a gradual decrease in surveillance as the teenager demonstrates their ability to manage alone.
This principle translates concretely into:
- Clearly defined and communicated stages
- Objective criteria for moving to the next stage
- Possibilities to go back if necessary
- Open communication about the process
7.2 Stages of Parental Disengagement
11-13 years: Active Supervision
At this age, close parental presence is still necessary. Control can be relatively tight, but always transparent. Emphasis is on media education.
14-15 years: Framed Autonomy
The teenager gains freedom, but regular checkpoints remain. Conversations about digital practices become more important than technical surveillance.
16-17 years: Responsible Autonomy
Technical control is reduced to minimum. The teenager is considered capable of managing their practices, with possibility to ask for help if needed.
18 and over: On-Demand Support
Legally adult, the young adult manages their digital practices alone. Parents can advise if solicited, but no longer have a control role.
7.3 Preparing to Leave Home
A teenager who has been closely monitored until age 18 then suddenly released into the digital world without a safety net is particularly vulnerable. Autonomy work must begin well before adulthood.
Ask yourself these questions:
- Does my teenager know how to recognize an online scam?
- Can they manage their screen time without external control?
- Have they developed critical thinking about content?
- Do they know how to protect their personal data?
- Do they have a healthy relationship with social media?
If the answer is no to several of these questions, the educational work isn’t finished, regardless of your teenager’s age.

Part 8: Parent Testimonials and Reflections
8.1 Claire, Mother of Two Teenage Girls
“I started monitoring my daughters secretly. I read their conversations every evening. One day, my eldest daughter sent me a message: ‘I know you read my messages. If you want to know something, ask me.’ I was mortified.
We talked about it, really talked. She explained what it felt like knowing I was violating her privacy. I had to admit I was wrong. Since then, we have another agreement: she regularly tells me what’s happening in her digital life, and I trust her. Paradoxically, I know much more than before because she really talks to me.”
8.2 Thomas, Father of a 15-Year-Old Boy
“My son developed an addiction to online games. I tried everything: parental control, surveillance, confiscation… Nothing worked. He always found a way.
What worked was understanding why he was fleeing into games. He felt excluded at high school, games were the only place where he had friends. We worked on the real problem, not the symptom. Today, he still plays, but in a balanced way.”
8.3 Sandrine, Mother of a Bullied Teenager
“I discovered my daughter was a victim of cyberbullying by reading her messages. She hadn’t told me because she was ashamed. This discovery allowed us to intervene and end the harassment.
Do I regret monitoring? No. Do I understand that she resented me? Yes. It took a long time to rebuild trust. Today, she tells me she would have preferred to talk to me herself, but she didn’t have the strength at the time.”

Conclusion: Finding the Right Balance
Should you spy on your teenager? The answer is neither a categorical yes nor no. It’s a question of balance, proportionality and purpose.
Systematic and secret spying on a teenager without particular reason is counter-productive and ethically problematic. It destroys trust, hinders autonomy development and can push the teenager toward riskier and more hidden behaviors.
But turning a blind eye to your teenager’s digital practices while invoking “respect for their privacy” is also not a responsible option. Online dangers are real and teenagers need support.
The middle way involves:
- Open and regular dialogue about digital practices
- Media education to develop critical thinking
- Transparency about forms of control exercised
- Progressiveness in granting autonomy
- Vigilance to warning signs without paranoia
- Proportionate intervention in case of real danger
At DYNSEO, we support parents in this educational approach with appropriate tools:
- Our “Screen Awareness” training gives you keys to understand and accompany your children’s digital practices
- Our screen awareness workshop offers concrete resources to address these topics as a family or at school
- Our COCO THINKS and COCO MOVES app offers an example of a digital tool designed for balance, with its integrated sports breaks
Discover the screen awareness workshop
The goal isn’t to control everything, but to prepare our teenagers to navigate the digital world alone. It’s long-term work that requires time, patience and lots of dialogue. But it’s the only investment that pays off in the long run.
