PromoMeld is a unified hub for subscriptions and useful notifications from stores, cafés, services, events, and online projects. Receive only what truly matters to you — without unnecessary spam, random subscriptions, or dozens of separate apps from different brands. PromoMeld is suitable for all kinds of projects — from small coffee shops or hair salons to stores, events, services, and online platforms. With PromoMeld, you can: • subscribe through the app or QR codes • receive notifications only from selected projects • keep all subscriptions in one place • temporarily disable notifications • view message history inside the app • choose notification formats • control notification frequency and delivery times • report unwanted or suspicious notifications With PromoMeld, you can receive: • promotions and discounts • news and updates • information about events and activities • important notifications • special offers The app gives you full control over notifications: • in-app notifications only • push notifications • silent mode • important notifications only PromoMeld works in two formats. The first is project subscriptions. Users voluntarily subscribe to projects they are interested in and receive notifications only when and as often as they choose. The second is quick access to information through QR codes without subscribing. For example, a company can place a QR code on a poster, package, business card, or advertisement. After scanning, users can instantly access information such as an address, map, menu, schedule, link, event details, or other materials — without requiring a subscription. PromoMeld also supports a feedback and reporting system. If a user believes notifications are unwanted, misleading, or spam-like, they can submit a report directly inside the app. Such reports are reviewed, and if necessary, a project may be restricted or blocked. For businesses, PromoMeld is a simple way to inform users without the need to create a separate mobile application. Companies create their projects through a web panel and distribute QR codes for subscriptions or quick access to information. PromoMeld does not create automatic subscriptions and does not send messages on its own. Users receive notifications only from projects they personally choose. The app is completely free for users. Platform usage is paid only by business accounts. PromoMeld is built around the idea of respecting the user. No automatic subscriptions. No aggressive spam. Only voluntary notifications, feedback, and full control.
