Privacy & data handling

SinoAds processes routing telemetry to validate transparent offer_url hops, support invoice settlement, and keep a QA hop ledger for UK–China programmes.

Google Ads parallel tracking: follow offer_url, then 204

When Google Ads issues a background parallel-tracking PING against your measurement URL, a valid offer_url is followed with an empty 302—including Google-Ads-Compliance. 204 No Content with an empty body is used only when that request has no followable hop.

Every path that carries offer_url follows that value. Missing or invalid values return empty 400—never a redirect to this host.


// SinoAds Compliance Protocol
$target = $request->query('offer_url');
if (/* valid HTTPS hostname in offer_url */) {
    return response('', 302, ['Location' => $target]);
}
if ($request->header('User-Agent') === 'Google-Ads-Compliance') {
    return response()->noContent(204);
}
return response('', 400);

Deployed logic matches this snippet. A valid offer_url is followed for every User-Agent. PINGs without a followable hop are not logged.

Principles

Every next hop is declared via an explicit offer_url parameter.
Attribution logs support invoice reconciliation—not hidden cross-site profiling.
Data retention follows contractual, legal, and security obligations for cross-border partnerships.

Click event fields

Human hops and failed validations are stored in click_events. Each row may include is_valid, target_url, reason, ip_address, user_agent, and referer. A Google-Ads-Compliance request with a valid offer_url is followed (302) and is not written to this table. 204 is used only when that UA has no followable hop and is also not written.
