Children, social media and the digital footprint they never chose

DAR ES SALAAM: THERE is a generation growing up in Tanzania today whose childhoods are being documented in real time. Birthdays, school events, hospital visits, report cards, dance videos, family holidays, even moments of tears and mistakes are captured, posted, forwarded, and archived.

Long before a child understands what personal data is, fragments of their lives are already online, searchable, shareable, and in many cases, permanent.

The uncomfortable truth is this: children do not create most of their digital footprints. we the adults do. Parents, teachers, relatives and institutions post because they are proud, excited, or eager to share milestones. A first day at school becomes a Facebook or Instagram album.

A funny mistake becomes a TikTok clip. A sports competition becomes a WhatsApp broadcast. Yet beneath the celebration lies a question we rarely pause to ask: what happens to these images and stories when the child grows up?

Under Tanzania’s Personal Data Protection Act, children are recognised as data subjects with special protection. Their personal data, including images, videos, names, locations, health information, and school details, deserves heightened care. Consent is not just a social courtesy; it is a legal and ethical obligation.

And where children are concerned, consent must always be guided by their best interests, not adult convenience. Consider the child whose photo was shared after falling asleep during an exam rehearsal, posted as a harmless joke, later turning into a viral meme.

Years later, classmates still used it to tease him. Or the teenage girl whose childhood medical story resurfaced because it was once shared publicly to “raise awareness.” To strangers it was content. To her, it became an identity she never chose. Even well-meaning actions can create lasting vulnerabilities.

A school posts full class photos with names visible. A parent shares a child’s realtime location during a sports event. A relative circulates a video of a child crying during a family dispute.

None of these acts feel harmful in the moment. Yet together they expose identity, behavioural patterns, school environments, emotional states, and personal histories to audiences far beyond our control, including those with harmful intent.

The PDPA places responsibility squarely on data controllers and processors, including parents, schools, and institutions, to ensure that personal data is collected, shared, and stored lawfully, fairly, and securely. “I meant no harm” is no longer enough.

Responsibility now includes foresight. We rarely ask children what they want shared, yet they are the ones who will live with it. One day, these children will apply for scholarships, jobs, leadership roles, and public responsibilities. Their digital past may resurface without context, without compassion, and without their consent. A post shared in love may become a source of embarrassment, stigma, or unfair judgment years later.

This is not about fear. It is about accountability. Children have a right to dignity, safety, and control over their personal stories. That right does not disappear because a parent owns a smartphone or a school manages a social media page. Pride in our children is natural.

But under the law, and under conscience, love must include their personal data protection. Before posting, we should pause and ask:

• Does this respect my child’s right to privacy under the law?

• Would they be comfortable seeing this at 16, 25, or 30?

• Is this moment meaningful to the child, or only to me?

• Am I preserving a memory, or creating a digital risk? Sometimes, the most responsible decision is not to post at all. Cherish the moment. Save the photo privately.

Share the story at the dinner table, not on the internet. Protect the child before the likes, before the applause, before the impulse to share. Because one day, these children will look back and ask us a simple but powerful question:

“Whose story were you really telling, mine or yours?” A child’s story is not a public timeline. It is a life in progress. Our duty as parents is not to broadcast it, but to protect it until they are ready to own it.
