Payment security

To ensure a high level of security and availability of the platform we placed it in a cloud service that meets the top ten security standards, has protection against DDoS attacks and ensures that there is no physical access by unauthorized persons and organizations to the data and equipment.

Every year we pass PCI DSS certification. We also developed and constantly update our own anti-fraud system consisting of three levels: barrier, analytical, post-operator. This means that the fraudsters have no chance.

Undocumented use of a 3rd Party / external service

This plugin integrates with the external payment service Flitt (https://flitt.com/) to create and process payments.

When a customer places an order, the plugin connects to Flitt to:
* create a payment / checkout session;
* redirect the customer or display an embedded payment form hosted by Flitt;
* receive payment status updates (callbacks/webhooks) and update the WooCommerce order;
* fetch transaction information required to complete the payment flow.

Data sent to Flitt may include (as required for payment processing): order identifier, amount, currency, customer billing/shipping details, and other checkout metadata. The exact data depends on the merchant’s Flitt configuration and the checkout scenario.

This third-party service is required for the plugin to function because payment authorization and processing are handled by Flitt.
