We collect and store information about which app features people use, and how and when they use them, in order to improve future versions of Anxiety Challenger. We do not collect personally-identifiable information such as names or email addresses that can be used to identify your patients. We store individuals' usage data with their therapist's referral code and an anonymized identifier derived from the users' Google Play account names. Individuals' identities cannot be derived from these anonymized identifiers.

As a therapist, you may use your own referral code to use the app in order to familiarize yourself with its features. Your usage data is also collected and stored. Please be aware that in this case, your identity can be associated with your usage data via your referral code.
