Orders: when you buy, our checkout provider processes your name, email, billing details and payment. We receive your name, email and order details so we can deliver your download and support you. We never see your full card number.

Contact: messages you send us by email.

To deliver purchases, provide support, send updates you asked for, and meet legal and tax obligations. We do not sell personal information.

We use third parties for checkout and payments, email delivery and website hosting. They process data on our behalf under their own privacy terms.

You can unsubscribe from emails using the link in any email, and ask us to access, correct or delete your information by emailing hello@example.com.
