It's true that Do Not Track (DNT) is not a true standard in terms of implementation and intent and different folks mean different things when setting the DNT flag. However, when building DNT for EthicalAds and for Read the Docs, we followed the EFF's implementation guide for DNT[1]. This means a number things including:
* We do not store personally identifying information when users are merely browsing a site with our ads.
* We rotate our logs in less than 10 days
* We do not set cookies on ad requests. We also don't use some non-cookie alternative. Obviously for publishers or advertisers, logging into our backend requires a login cookie.
