The Library subscription is billed monthly or annually through Stripe. Your card is charged at the start of each billing period. The trial period (currently 7 days) is free; billing begins automatically on day 8 unless you cancel beforehand.
You may cancel at any time from your account page. Cancellation stops future billing and keeps the subscription active through the end of the paid period — no partial-period refunds are issued for mid-cycle cancellations (see the Refund policy for the exception that applies to new subscribers).
We reserve the right to change subscription pricing with 30 days' notice by email to registered subscribers.
