Review your plan, usage and renewal date in Billing, then confirm account changes securely in Stripe.
Upgrade or change billing frequency
Open Billing. Free accounts can choose a paid plan and billing interval, then review checkout. Existing subscribers use Change plan or the plan-card controls to open Stripe’s subscription update screen. Review the selected plan, billing interval, any proration and the effective date before confirming. AP3K synchronizes the resulting subscription through Stripe webhooks.
Do not start a second checkout to repair a payment problem. Payment-due, incomplete and unavailable subscription states should be resolved through billing management or support.
Cancel renewal or keep a subscription
Select Cancel subscription to open Stripe’s confirmation flow. AP3K’s portal is configured to cancel at the end of the paid period, preserving access until then. Review the effective date shown by Stripe. If cancellation is already scheduled, open Keep subscription to manage renewal in the portal.
Use Manage subscription for invoices and billing history, or Payment method to review your saved payment method. These controls open Stripe; opening a portal page alone does not confirm a purchase or cancellation.
When billing cannot be verified
Refresh the page if Stripe is temporarily unavailable. If a saved customer record cannot be found, contact support@ap3k.com with your billing email. AP3K preserves your existing plan while the account link is reconciled instead of encouraging another charge. Do not send card details or passwords.
