Manage your subscription
Paste your Pro API key to open Stripe's billing portal, where you can update your card, download invoices and cancel.
What cancelling does
Your key is derived from your subscription, so when the subscription stops being active the key stops granting Pro access and falls back to the free allowance. Nothing else has to happen and there is no account to close, because there is no account.
Lost your key?
Reissue it yourself at recover your API key using the subscription id from your Stripe receipt. Because the key is computed from the subscription rather than stored, what you get back is the identical key, so anything already configured with it keeps working. See the terms and the privacy policy.
