Summary
DLP Nederlands does not use advertising cookies, Google Analytics or cross-site trackers. We use strictly necessary cookies, local learning settings, a tab analytics ID and a privacy-minimised first-party browser ID used only to measure anonymous return days. Cloudflare Web Analytics measures aggregate page views and performance without cookies, local storage or a persistent visitor identifier.

Managing storage
You can delete or block cookies and site data in your browser settings. This may sign you out, remove unsynchronised progress and reset settings. Because we currently use no optional tracking cookies, we do not show a separate cookie banner. Before adding optional cookies or third-party embeds, we will assess whether prior consent is required.
