Spenzai is a minimalist, privacy-focused expense tracker (PWA) for individuals who value simplicity and control over their financial data. It works offline using localForage and syncs online with Appwrite for backup. The app features encrypted local storage, no ads or analytics, and a clean UI for adding and viewing expenses. It solves problems of bloated UIs, lack of offline access, and privacy risks in other apps. The project aims to empower users with secure, cross-device access to their spending data while being open-source and easily self-hostable.
