Know what you’re buying.

Zhenzhu Pro is a one-time US$29 purchase covering Pro features in Zhenzhu, with all future updates included. It is not a subscription. Early supporters may receive a lower price through a limited discount code shown on this site and applied at checkout.

The Free plan has no time limit. It includes unlimited lookups and reviews, plus 15 new cards and 20 OCR reads each calendar month.

Pro 1 licenses bought before October 14, 2026 keep their original terms: Pro features in Zhenzhu 1.x and updates within that major version. Lifetime Updates licenses bought before that date are Zhenzhu Pro licenses.

Prices are listed in US dollars. Review the currency, applicable taxes, and final total shown by Lemon Squeezy before paying. Future features and release dates are not guaranteed.

Each paid license covers up to 3 Macs. Keep your license key private. Zhenzhu requires macOS 15 or later, and first activation requires an internet connection.

After purchase, use the activation link or license key associated with your order. If you need help with an activation or a replacement Mac, contact support.

If Zhenzhu is not right for you, email nguyenducminh.dev@gmail.com within 14 days of purchase for a full refund. Include your order number and the email used at checkout. You do not need to give a reason.

Refunds are processed through Lemon Squeezy to the original payment method. A refunded purchase no longer includes a Pro license; you can continue using the Free plan.

This policy does not limit any rights you have under applicable consumer law or Lemon Squeezy’s buyer terms.

Lemon Squeezy processes purchases as merchant of record. Its buyer terms apply to checkout. Keep your receipt for purchase and license support.

Email nguyenducminh.dev@gmail.com for product, billing, or refund questions. Do not include card details or a full license key.
