How do I manage my subscription and billing?

Sign in and open Settings → Account. From there you can:

• See your current plan and addons.
• Start checkout for Basic or Pro via Stripe (/settings/subscription/checkout/{priceId}).
• Open the Stripe billing portal to update payment methods, invoices, or cancel.

After a successful checkout you are returned to the subscription success page. If you cancel checkout, you go back to account settings without changing your plan. Stripe webhooks at /stripe/webhook keep subscription status in sync.
