The service collects and submits anonymous aggregated data about which app features are being used most frequently as well as your mobile device UDID (unique phone Identifiers) and/or IMEI (International Mobile Equipment Identities), which are also anonymised via a secure hashing protocol, to Adobe servers. This information will be used to continually improve the features and functionality that DK releases in its subsequent versions of its mobile apps."
