Some of the websites for the relaxation apps linked to privacy policies that lacked enough detail to understand the full scope of whether and how the app collected data about the user. For example, some of the relaxation apps’ policies referred to a “website” rather than an app 25, contained only a single sentence about privacy 37,38, or had a Google Play Store link for a privacy policy that was on a different website from the app manufacturer and did not clearly refer to the app. 23 Thus, slightly less than half (47%) of the policies for relaxation apps both clearly applied to the app in question and had at least some substantive content.
