Founding offer
US$49 as a one-time payment, with 12 months of updates and email support for one store. No automatic renewal. Any applicable tax and the final total will be displayed at checkout.
Updates are installed manually by uploading a ZIP. An automatic updater is not included in version 0.1. The plugin is distributed under GPL version 2 or later; the one-store scope describes the paid support entitlement, not a restriction on GPL rights.
30-day refund policy
You may request a full refund within 30 days of purchase. Email [email protected] with your order number and purchase email. Do not send payment-card details. Refunds are processed through Lemon Squeezy; bank processing times can vary. This offer does not limit mandatory consumer rights or Lemon Squeezy’s own refund powers.
Delivery and support
After checkout, access the plugin ZIP through your Lemon Squeezy receipt or purchase account. Follow the installation guide. Email support aims to provide a first reply within two business days, Monday–Friday, Europe/Istanbul. See the support scope. After 12 months you can continue using your installed GPL plugin; there is no automatic renewal or promise of lifetime support.
