We require a payment method to prevent abuses and ensure the seriousness of the user. Your payment info is safe and will never be charged without your knowledge.
Classtra does not charge any upfront fees. You are only charged based on your usage at the end of your billing cycle. Each billing cycle is 30 days. If you use no features, you won't incur any charges. You can always preview your upcoming bill by visiting the billing page. The Basic plan has a transaction fee taken directly from the charges. But SMS & Storage costs are withdrawn from the payment method.
