Does Leadoo use cookies?

August 21, 2020

Yes. Leadoo does still use cookies, but as third-party cookies are being phased out by most browsers we no longer rely on them. In addition, it’s also common for users to periodically empty their browser’s cache. 

Leadoo is however future proof, for the time after cookies, as we use HTTP header ETags to identify a user. Technically this is a more robust way when browser cookies are iffy already today. In terms of user compliance for tracking them, the same is required by eTags as is required for cookies for instance by GDPR.

What are Etags?

ETags are a way to track different browsers, similar to how cookies are used. Technically the implementation details are a bit different. ETags are built for recognizing if the web browser already has an asset (such as an image or video) so that the server doesn’t need to send it over the wire again.

In practice, eTags are used in a similar way to cookies to fingerprint a user and to know that a browser that visits the site right now is the same one that visited the site a week ago.
