FlexExt Darowizny dla Przelewy24 Lite is a lightweight, secure, and accessible WordPress donation plugin built for collecting online donations (darowizna / darowizny) in Poland through the Przelewy24 (PayPro SA) payment gateway.
Designed specifically for Polish non-profit organizations, foundations (fundacje), associations (stowarzyszenia), charities, parishes, content creators, and open-source projects. Visitors can donate instantly using Poland’s most popular payment methods: BLIK, fast online bank transfers (pay-by-link), and credit/debit cards (Visa, Mastercard).
