Most POS apps lock features, delete your history, and mine your data. KasirCepat is different: 100% offline-first (not a fallback), data never leaves your device, transaction history never auto-deleted, and free forever for 1 device with unlimited products. Available on Android, Windows & Linux. Built for warung and small shops in Indonesia. Pro plan is $8/year for multi-device via local WiFi — no cloud needed.
