Corollary Cloud — Pro & Max

Corollary doesn't run an account dashboard — your billing lives at Lemon Squeezy, our payment processor. From there you can view invoices, update payment method, change plan, or cancel.

Open the customer portal

Lemon Squeezy will email you a magic-link to access the billing portal. No password required — enter the email you used at checkout.

Common tasks

Lost your license key? Open the portal and check the email associated with your subscription — the key is in your original order-confirmation email. Still missing? Email corollary@grimvier.com with your order ID.
Upgrade Pro → Max: Cancel the current subscription, then resubscribe to Max — your existing Pro key stays active until the period ends. Lemon Squeezy may offer in-portal upgrade flows; use those when available.
Downgrade Max → Pro: Cancel Max from the portal, subscribe to Pro from /upgrade when you're ready. Your new Pro key arrives by email.
Cancel: Cancellation takes effect at the end of your current billing period. Access continues until then.
Refund within 14 days: No questions asked. Email corollary@grimvier.com.

What lives in the extension

Your license key lives in the extension's settings (synced via Chrome's chrome.storage.sync). The current tier, remaining Premium credits, and Fast-track quota are visible on the sidebar badge. None of this requires logging in.

Corollary Cloud is billed through Lemon Squeezy, who act as the merchant of record. They handle VAT, sales tax, invoices, and PCI compliance. Your card details are never stored on Corollary's servers.
