Věrnostka is a loyalty program platform for small and medium businesses in the Czech Republic: cafés, restaurants, bakeries, barbers and hair salons, beauty studios and gyms. A business gets its own branded loyalty card in minutes, with no development and no change of its cash register. Customers scan a QR code at the counter and collect stamps (e.g. 10 + 1), points, coupons or prepaid passes in the Věrnostka app or in the browser; the staff confirm visits in a browser-based counter app that works alongside any POS. Higher plans add a PWA app without installation, seven marketing automations (welcome, win-back, birthday, expiry, visit reminder), customer segments and a post-visit survey that invites happy customers to leave a Google review. Multi-branch management with roles and an API for POS integration are available for chains and franchises. Plans start at 490 CZK per month with no setup fee and no lock-in; data is hosted in the Czech Republic and the GDPR toolkit (consent, export, deletion) is built in. The interface is available in Czech and Vietnamese.
