Changing your plan, going yearly, or cancelling

Everything is on My account › Billing.

• Change plan: press the plan you want and approve it in PayPal. New features start straight away; the new price starts at your next payment.
• Cancel: Billing › Cancel subscription. Nothing more is charged and your plan keeps working until the end of the period you already paid for.
• Subscribe again later: pick a plan on the Pricing page — if you're still inside a paid period, the first charge waits until it ends.

You can also cancel from your PayPal account (Settings › Payments › Automatic payments).
