1. In the app, click Buy for $39 in Settings › Account, or Buy on our website when the trial ends. You can also sign in on the account page and buy there.

  2. Pay at checkout. Any sales tax or VAT is shown before you pay. Payments are handled by RevenueCat and Stripe; we never see your card.

  3. After paying, your browser offers to open Second Display, which then picks up your licence. Your receipt arrives by email.

The licence is active as soon as the payment goes through. If the app still shows the trial, check that you’re signed in with the email you used at checkout, then click I already purchased or reopen the app: it looks for your licence each time it opens.

It’s not a subscription: $39 once, with every future update.
