Frequently Asked Questions
Everything you need to know about using this application.
How do I save my habit data without using local storage?
Since this application operates in a strictly sandboxed environment without local storage or database access, we utilize a local file-based export and import system. You can save your habit progress at any time by downloading a JSON file to your device, which preserves your current streaks and settings. To resume your tracking, simply click the 'Import Data' button and select your previously saved JSON file. This ensures your data remains completely private and under your control while respecting the limitations of a browser-based, client-side application.
Is my habit data shared or stored on a server?
No. This tool is built entirely as a client-side application, meaning all processing happens locally within your web browser. There is no server-side component, and no data is ever transmitted, stored, or processed by an external database. Your habits and streak history exist only in your browser's active memory for the duration of your session. By relying on manual file exports, you maintain total ownership of your information, ensuring that your productivity metrics are never exposed or tracked by third-party services.
Can I track multiple habits simultaneously?
Absolutely. This tool is designed to manage multiple habit chains concurrently, allowing you to create a personalized dashboard for your entire daily routine. Each habit you add appears as an independent row with its own interactive calendar grid and streak counter. You can easily add, rename, or remove habits as your goals evolve. The visual layout ensures that you can see your progress across different areas of your life—such as fitness, reading, or professional development—at a single glance.
Does this tool work on mobile devices?
Yes, the application is built with a responsive design framework that adapts fluidly to various screen sizes. Whether you are accessing the tool from a desktop computer, a tablet, or a smartphone, the interface will automatically adjust to provide an optimal viewing experience. The interactive calendar grids and input controls are designed with touch-friendly dimensions, making it just as easy to mark off your daily habits on your phone as it is on a larger workstation.
