Everything about your subscription is under Settings → Plan & billing.
- Upgrade to Starter or Pro, monthly or yearly (yearly saves money). Payment runs through Stripe; invoices for your subscription are in Manage subscription.
- Switch plan or interval at any time; Stripe settles the difference.
- Cancel subscription asks one question and offers a 3-month pause instead. Cancelling keeps your plan until the end of the paid period; then you are on Free. Nothing is deleted.
- If a payment fails, a banner asks you to update your card; your plan stays while Stripe retries.
