While your Sideline subscription begins on the first day you start your free trial, you'll have the first 7 days to try out Sideline without being charged.
FYI: The payment method you currently have on file with your App Store will be charged after the free-trial period has ended.
Google Play Store (Android users):
According to the Google Play Store, you may be charged up to 72 hours before each subscription period starts.
This means, on your 6th day of the trial, you may receive an alert for a pending charge. This is a result of the pre-authorization process in place by Google. If you have questions about this, we recommend reaching out to Google Play Support.
