Privacy
You can read and practise breathing without signing in. In that case, everything stays on your device. This page explains what is stored when you sign in.
When you are not signed in
Read marks, reading position, breathing history, your theme choice and listening preferences (speed and automatic playback of the next article) are kept in the browser's storage (localStorage). They never leave your device. Zenbox uses no tracking cookies and no third-party analytics.
