Frequently asked questions
Do I need a Heartly account?
Yes. This plugin is the WooCommerce-side bridge for the Heartly platform. Without a Heartly account the plugin has no effect. You can sign up free at heartly.io.
Will this affect my normal WooCommerce functionality?
No. The checkout redirect and coupon logic only activates when a customer arrives via a Heartly flash sale URL (URL contains flash_sale_id or heartly=1). All standard WooCommerce behavior is unchanged.
Can I disable the auto-redirect to checkout?
Yes. Go to WooCommerce → Heartly and uncheck Auto-Redirect to Checkout.
What data is sent to Heartly?
When the plugin is active and connected, the following data is sent to heartly.io: Your store’s checkout and cart URLs (on activation and once every 24 hours) Product price changes (used for PAngV compliance price history) Order metadata when a purchase originates from a Heartly flash sale (flash sale ID only) A deactivation signal when the plugin is deactivated No customer personal data (name, email, address) is ever sent to Heartly.
Is this GDPR compliant?
Yes. The plugin does not collect or transmit customer personal data. Order tracking only stores the internal Heartly flash sale ID as order metadata. A GDPR data exporter and eraser are included for completeness.
