About

Stranger

Read full description

Stranger is an anonymous audio network about how we sound after surrendering how we are heard. The application runs passively in the background and listens to the world around you. When something feels meaningful, it keeps what it hears. The system decides what slips through. These moments are shared with one anonymous stranger. In return, pieces of their day arrive to you, uncurated and unedited. You're bound to just one person at a time. No context, no identity. Just an unfiltered exchange of life as it happens. ––––––––––––––––––––––––––––––––––––––– This software requires a paid subscription. Your subscription sustains an approach built without tracking, without selling user information, and without advertisements. The system operates without exploiting user attention. There is no reliance on engagement based monetization. Your support allows this to exist without compromise. ––––––––––––––––––––––––––––––––––––––– By using this app, you are agreeing to our Terms of Service (strangernetwork.com/tos.html) and Privacy Policy (strangernetwork.com/privacy-policy.html). ––––––––––––––––––––––––––––––––––––––– For all questions and enquiries please contact (connect@strangernetwork.com).
