# SamparkWA by Trustoryx

> SamparkWA is a privacy-first Chrome extension that helps small businesses send personalized WhatsApp customer reminders without risking account bans. It uses a human-in-the-loop approach where every message requires explicit human confirmation inside WhatsApp Web — zero automation, zero ban risk. All customer data (contacts, templates, opt-out registry) is stored locally in the browser's IndexedDB — no data ever leaves the device. Supports English, Hindi (हिन्दी), and Hinglish with 25+ ready-to-use templates. Free forever. Parent company: Trustoryx (https://trustoryx.digital).
