How do I cancel my free trial?
Open the billing page at gyrosco.pe/billing and choose Downgrade to free. Your card will not be charged.
The trial benefits end that day and your account returns to the free app, with 30 days of data storage. Future free trials are not available for that account.
If you started the trial in the App Store, cancel it from your Apple subscriptions list instead, since Apple bills those directly.
When is the first payment?
While you are in a free trial, the billing page shows that your card has not been charged yet, with the amount and date of your first payment.
