Yes, Trio Education has an auto-renewal feature enabled by default for subscription plans. When your current subscription period ends, the same plan will be automatically renewed, and the associated fee will be charged to your account.
If you prefer not to use the auto-renewal feature, you can disable it. You can easily manage your subscription settings in the billing section. By canceling the auto-renewal, your plan will remain active until the end of the current billing period, with no further automatic renewals.
