Without the internet. Send money. Check your balance. Scan QR codes. All over plain 99# USSD on your SIM. No data, no Wi-Fi, no account. Website · PWA · Download APK Type. Tap. Done. Real bank confirmation. Fully offline. --- Why OffPay Every other UPI app needs the internet. In huge parts of India, that's a luxury. 99# is a USSD-based UPI service that works over your SIM's voice channel (no data needed). The catch: dialling raw codes and typing UPI IDs on a number pad is brutal. OffPay puts a clean app on top of it. Same modern feel as GPay or PhonePe: type, scan, tap. Zero bytes of data used. Built by Lakshya & Harsh. Side project, not a registered payment service. Your PIN, your data, your transactions: they never leave the device. --- What you get 🌐 Fully offline  ·  no Wi-Fi, no mobile data: just a SIM with voice signal. 💸 Send money  ·  UPI ID, amount, optional note, your PIN. ₹1 to ₹5,000 per transaction. 📷 Scan or import QR  ·  live camera with pinch-to-zoom, or pick any QR image from gallery. 🏦 Check balance  ·  one tap, straight from the bank. 🧾 Encrypted history  ·  last 200 successful payments, on-device, encrypted. 🚫 Zero tracking  ·  no analytics, no ads, no servers, no account, zero outbound requests. 🛡️ PIN never persists  ·  held in memory only, wiped within 500 ms of every session. ✨ Polish  ·  custom success/failure animations, haptics on every tap. -","default_branch":null,"files":null,"tree":[],"storefront":"/r/laksh-ya","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/laksh-ya/OffPayApp/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
