Manage your billing from Settings → Billing on your dashboard.
The billing page shows:
Pro and Elite plans are sold as a one-time lifetime purchase. Once you've paid, you have permanent access to your plan's features — no renewals, no recurring charges, no expiry date.
To upgrade from Pro to Elite, go to Settings → Billing and click Get Lifetime on the Elite plan. You pay the Elite one-time price and your plan upgrades immediately.
Payments are processed securely through Stripe. You can view your payment receipt directly in your email after purchase.
