This one is for parents and for heads, because the rule affects both.
Schools take photographs. Sports day, the science fair, the new classroom block. A school on Clarvyn keeps them in a media library, shares them with the families concerned, and can choose to show some on its public page at clarvyn.ai. Somewhere in that sentence is a child's face on a web page that search engines index, and that is where the rule lives.
The rule
A photograph with a child tagged in it cannot be shown on a school's public page. Not by a head, not by the office, not by anyone at Clarvyn. There is no override.
Tagging is how a school says who is in a picture. When a photograph is tagged with a child, it reaches that child's parents in the app, and it becomes a photograph of a named child. The rule follows from that: a picture of an identified child is for the people the school knows, not for the open web.
How it is enforced
In the school console, a photograph in the media library has a button, Show on the public page. Pressing it asks what the picture shows, in words a screen reader can read aloud, and then offers Publish it. A published photograph shows a label, On the public page, and a button, Take it down.
A tagged photograph never gets that far. It shows Not for the public page instead, with a note saying how many children are identified in it and that the tags would have to be removed first. If the console were somehow bypassed, the server refuses the same request with the same reason: a photograph with a child tagged in it cannot be shown on your public page. And underneath the server, the database itself refuses to store a photograph that is both tagged and public. Three refusals, one rule, so that no future feature and no mistake can route around it.
The half people miss
Tagging happens later. A school publishes a photograph of the courtyard today. Next term somebody tags three children in it, doing an unrelated job, thinking nothing of the public page.
The moment that tag is saved, the photograph comes off the public page. Nobody is asked and nobody has to remember. The public site stops serving the picture within a few minutes, and the school's page simply has one fewer photograph. If the school wants it back, it can remove the tags and publish it again, which is a decision somebody makes deliberately.
We chose silent removal over refusing the tag. Refusing would block a legitimate act, recording that a child is in a photograph, to protect a decision made about a different question, and a school would work around it by not tagging. Fewer public photographs is the only way this can fail safely.
The banner photo
A school's page opens with one wide photograph across the top. It is uploaded on the profile form, not from the media library, and the form says beside it: take your own, and do not use a photo of children from the gallery.
That is a rule the form states rather than one the system enforces. The banner is a separate upload and the tag check does not run on it. So this one rests on the head who chooses the picture. A courtyard, a gate, the school building on a bright morning: all fine. A class photograph is not, and if a parent sees one there, we would like to hear about it.
What this means for a parent
If your child is tagged in a photograph, you see it in the Clarvyn parent app under your child's Photos tab, and so do the parents of any other child tagged in the same picture. That includes class photographs, so you will sometimes see other people's children, and the app tells you how many other children are in each picture rather than letting you assume every face is yours.
Those photographs are behind sign-in, for guardians the school has recorded. They are not on the public page, and the rule above is what keeps them off it.
What this means for a head
Tag generously and publish carefully. Tagging is how families get the pictures of their own children, and the rule means you can tag without worrying about the public page, because the system handles that side. When you do publish, choose the photographs that show the school: buildings, grounds, the work on the walls. If you want a picture with children in it on your public page, it must be one nobody has tagged, and you should be sure you have the consent to use it that way. Clarvyn does not manage that consent for you. It only makes sure a tagged child never ends up on the open web by accident.
