Privacy

Breathster is free. There are no ads, no payments and no tracking scripts. Here is everything the site keeps.

Your microphone

In microphone mode, the game measures how loud the sound of your breath is, directly in your browser. Audio is never recorded, saved or sent anywhere.

Your account

When you create a free account we store your email address, when you signed up and when you last signed in. We use your email only to send you sign-in codes. We never sell it or send marketing email.

Your flights

For signed-in players we save each flight's breathing pattern, number of breaths, clean landings, score and steadiness, so you can see your progress.

Cookies and storage

One cookie keeps you signed in. Your browser's local storage remembers your settings, best score and whether you've used your free flight.

Deleting your data

To delete your account and all your flights, email the address that sends your sign-in codes and ask us to remove it.

Breathster is a relaxation game, not a medical device. If slow breathing makes you dizzy or uncomfortable, stop and breathe normally.
