The words of audience measurement, defined without the detour
Pseudonymisation, DPA, SDK, referrer: the vocabulary of analytics and the GDPR, one definition per page, with a link to the guide that goes further.
DPA Data processing agreement
A DPA is the contract framing the processing of personal data entrusted by a controller to a processor: it sets out what the processor is allowed to do, and nothing else.
Personal data PII — personally identifiable information
Personal data is any information relating to an identified or identifiable natural person, directly or indirectly, including by cross-referencing with other information.
Pseudonymisation
Pseudonymisation replaces the data that directly identifies a person with a substitute identifier, so that they can no longer be recognised without information kept separately.
Referrer
The referrer is the address of the page a visitor came from, sent by the browser in the HTTP header of the same name.
SDK Software development kit
An SDK is a set of tools published by a vendor to integrate its service into an application: a code library, documentation and examples, bundled so you do not have to write the integration yourself.
Single page application SPA
A single page application is a site that loads one HTML page and then replaces its content in JavaScript on every navigation, without ever reloading the full page.
