The UK's Online Safety Act has forced adults & children around the world to enter highly personal, sensitive & often immutable information into random, untrusted websites.
The OSA Under 18 extension is free & intended to be installed by concerned parents with a view to protecting their children, without the need for invasive data sharing.
The OSA - Under 18 extension adds a unique "x-osa-under18" header to every request - allowing websites to check for it before deciding which content to display.
Unlike other "privacy-preserving" methods - this extension neither collects nor shares ANY user data with anyone.
The extension will never collect, share or leverage any user data - directly or indirectly.
All incoming requests, top-level navigation or XMLHTTP, will include an "x-osa-under18" header. The existence of this header means your visitor is under 18.
A simple bool check allows you to decide if you should show content.
