May I purchase a subscription only for a time frame?

Olá! Estou interessada em fazer o plano bronze. Gostaria de saber se tem tempo mínimo para me manter no plano ou posso pagar por 2 meses por exemplo e depois voltar para o gratuito.

Att, Daniele.

The minimum is 1 month, it's not possible to have a subscription active less than that. The max number months is decided by the user; however, the subscription needs to be cancelled right before the next billing date so the account is downgraded, otherwise your subscription will keep active as long as you do note request the downgrade. 

You could purchase your subscription and cancel it after the first month is passed, this way you do not get charged for a third month and instead your account is set back to free. 

The following guides will help you upgrading and downgrading your account:
