Englehardt installed replay scripts from six of the most widely used services and found they all exposed visitors' private moments to varying degrees. During the process of creating an account, for instance, the scripts logged at least partial input typed into various fields. Scripts from FullStory, Hotjar, Yandex, and Smartlook were the most intrusive because, by default, they recorded all input typed into fields for names, e-mail addresses, phone numbers, addresses, Social Security numbers, and dates of birth.
