Facebook Tracker

Facebook’s centre of gravity has moved to older users, and teenagers know it. A fifteen-year-old typically has a Facebook account because a relative insisted, because a football club posts fixtures in a private group, or because Messenger is the only app a particular friend or cousin uses. The main Facebook app may sit unopened for days. Messenger, on the other hand, may be busy, and Marketplace can become a regular destination once a child has something to sell or a hobby to fund.

That pattern is why the panel tracks Facebook and Messenger as two apps. A child with twenty minutes a week in Facebook and an hour a day in Messenger is using it as a messaging service, and the questions that matter are about who they are messaging. A child with a sudden rise in Facebook app time is more likely browsing Marketplace or has been pulled into a group, and the questions are about money and strangers.

Messenger chats are now end-to-end encrypted by default, and the Facebook account sits behind your child’s login. Products that promise to show a parent the Messenger inbox do so by asking for the child’s password, which Meta treats as a compromised account, or by capturing the screen. Neither is something MobileTracking does or recommends. What Android does permit, with a permission your child grants, is seeing how long each app is in use and what appears in the notification shade. That is the tracker’s whole footprint.

Facebook’s minimum age is 13. Messenger has a separate under-13 product, Messenger Kids, which is parent-managed and does not appear as ordinary Messenger. If regular Facebook or Messenger shows up on a younger child’s phone, the new-app alert reaches you the day it happens, and the install date stays on the card so you can see how long it has been there.

For each app the panel shows minutes today, the weekly pattern, and how the figure compares with everything else on the phone. Messenger’s share of your child’s total messaging is a useful ratio: if most of their conversations happen there rather than on WhatsApp or Snapchat, the people they talk to are likely to include adults from the wider family and community, which is generally fine, and possibly adults they met through a group or Marketplace listing, which is worth knowing about.

The keyword alert works across both apps. When a listed word appears in a Facebook or Messenger notification preview, the panel logs the word, which app it came from, and the time. Facebook notifications are mostly about group posts, reactions and Marketplace messages; Messenger previews show the start of a message unless previews are turned off. In either case the alert never includes the message, the sender, or the thread. It is an invitation to ask, not a transcript.

• Facebook installed or not, with the date; Messenger the same, separately.
• Daily minutes and weekly pattern for each app.
• Messenger’s share of all messaging time on the phone.
• New-app alerts for either app.
• Optional word matches from notifications, with the word, app and time only.

Facebook Marketplace is available to any account holder aged 18 or over according to Facebook’s rules, but in practice many younger teenagers use it through their own account or a parent’s. The appeal is obvious: a used phone, a bike, concert tickets, trainers. The risks are equally concrete. Sellers who ask for payment by bank transfer or a friends-and-family payment before shipping, then vanish. Buyers who send a fake payment confirmation screenshot. Ticket listings for sold-out events that never existed. And the oldest risk of all: a meeting in person with someone the child knows only from a listing.

A rise in Facebook app time is often the first sign a child has started using Marketplace, and it is a good time to set some ground rules together. Never pay before receiving an item unless the platform’s own checkout is used. Never meet a seller or buyer alone, and only in a public place in daylight. Treat any request to move the conversation to another app, or to pay by transfer or gift card, as the end of the deal. Tell a parent before agreeing to any purchase over a small amount.

None of these rules requires reading messages. They require a child who knows the patterns, and a parent who asked at the right moment. The panel provides the moment.

Messenger separates messages from friends, which arrive in the main inbox, from messages from other people, which go to “Message requests”. Meta applies extra restrictions to accounts of under-16s, but a child who entered a false birth date does not get them, and a child with a large friend list has effectively opened the inbox to anyone on it. The setting worth checking is Privacy, then “Message delivery”, where each category (friends of friends, people with your phone number, others on Facebook) can be routed to the requests folder or blocked entirely.

The second setting is the Facebook friend list itself. Teenagers accept requests from names they half-recognise, and each acceptance is also a Messenger contact. A periodic tidy, done together and without drama, keeps the inbox to people the child actually knows. It is also worth turning off “Active status” so that contacts cannot see when the child is online at night.

If the panel shows a jump in Messenger time or a keyword alert from Messenger, a natural question is “Has anyone new messaged you on there? Anyone you don’t know in person?” Children answer that readily when the parent has been open about what they can and cannot see, and evasively when they suspect the parent already knows the answer.
