How can we help?

FAQ

• How do I cancel Premium?

  We offer a 14-day, no-questions-asked refund. Request it via paddle.net or email us.

• Where's my invoice?

  Our Merchant of Record, Paddle, issues invoices and emails them as PDF after purchase. You can also redownload them any time at paddle.net.

  Yes. Email us with an 'account deletion' request; we remove everything within 30 days. Legally required records (invoices) are retained per law.

• I forgot my password. Now what?

  Use 'Forgot password' on the sign-in screen. We'll email you a reset link.
