Cookie notice
This page lists every cookie the app sets. There are few, and none of them track you. The privacy policy covers the rest of your data.

What is not a cookie
Some settings, such as the voice you chose for listening or whether sound is on, are kept in your browser’s local storage. They stay on your device and are never sent to us.
What we don’t use
No analytics, advertising or third-party cookies. The app loads every script, font and stylesheet from its own server.
Why there is no cookie banner
Every cookie above either makes the site work or remembers a choice you made, so nothing needs your consent and there is nothing to accept or refuse.
Do Not Track and Global Privacy Control
Your browser may send a Do Not Track or Global Privacy Control signal. It changes nothing here, because nothing on the site tracks you.
Clearing cookies
You can delete cookies in your browser’s settings, usually under Privacy
or Site data. Deleting sid signs you out. Deleting lang puts the app
back in your browser’s language. The app sets tz again the next time
you start a Sprint session.
