Spentt is a free personal expense tracking application designed to help users log, categorize, and understand their daily spending. The app prioritizes user privacy by storing all financial data exclusively in the user's own Google Drive, ensuring that the developers never have access to the information. There is no requirement to link a bank account or provide a credit card, and no sign up fee is charged. Users simply sign in with their Google account to begin tracking. The application is built for speed and simplicity, allowing users to log an expense in approximately five seconds. Key features include the ability to categorize spending, view a weekly spending receipt or summary, and gain insights into spending habits. The workflow is straightforward: a user records an expense, the app categorizes it, and the data is saved directly to the user's Google Drive. This approach gives the user complete control and privacy over their financial records, as the data never touches Spentt's servers. Typical use cases include individuals who want a quick and private method for tracking daily purchases without the complexity of full budgeting software. It is suitable for users who prefer to maintain ownership of their data and are comfortable using a Google account for authentication and storage. The app is accessible via its website at https://www.spentt.live and is intended for personal finance management.
