How do I upgrade, downgrade, or cancel my plan?

Go to Settings → Billing. Changing plans takes effect immediately:

• Upgrading unlocks the new plan's features and AI credit allotment right away.
• Downgrading takes effect immediately too — you'll drop to the lower plan's limits (for example, Pro → Starter drops you to 1 workspace and a 7-day activity history window).
• Cancelling stops future billing; you keep access through the end of the period you already paid for. If you're in the Pro yearly trial, cancelling before day 3 means you're never charged.

Billing is handled by our payment provider, Polar — you'll see their checkout when you upgrade, and can manage your card/invoices from the same Settings page.
