Billing details

Renewal
Subscriptions renew automatically every month at the price shown above, until you cancel. If we ever raise that price, we'll email you at least 30 days before it applies, and it only takes effect from your next billing period -- so you can always cancel first.
Cancelling
Cancel any time from your account's subscription settings. You keep full access until the end of the period you've already paid for -- cancelling stops future renewal charges, but doesn't cut you off mid-period, and doesn't issue a refund on its own.
14-day money-back guarantee
First-time subscribers can request a full refund within 14 days of their first payment, no explanation needed. This covers your first payment only, not renewals -- though if a renewal charge was a genuine mistake, email us and we'll normally refund it.
Taxes
Every price on this page excludes applicable tax, which is calculated at checkout based on your location.
