HOW DOES HEAD BOOSTER WORK?
After you decide to try the Head Booster app, you can start a 7-day free trial.
Unless you cancel at least 24 hours before the end of the free trial, you will be automatically charged a price indicated on the payment screen for a chosen subscription period.
The Head Booster Premium subscription renews automatically at the end of each period (depending on the selected option) until you cancel. Canceling your subscription means the automatic renewal will be disabled. However, you will still have access to all your subscription features for the remaining time of your then-current period.
