Frequently Asked Questions
Yes! The core statistical tools and features of StatFusion are completely free to use. In the future, we may introduce premium features for advanced analyses, but our commitment is to keep essential statistical tools freely accessible to everyone.
StatFusion processes all data directly in your browser. Your data never leaves your device or gets sent to our servers. This ensures complete privacy and security when working with sensitive information.
StatFusion is optimized for small to medium-sized datasets (up to several thousand observations). Due to browser memory constraints, very large datasets may cause performance issues. For extremely large datasets, traditional desktop statistical software may be more appropriate.
StatFusion works best on modern browsers that fully support WebAssembly, including: - Chrome/Chromium (version 90+) - Firefox (version 90+) - Safari (version 15+) - Edge (version 90+)
We recommend keeping your browser updated to the latest version for the best performance.
Currently, StatFusion requires an internet connection for the initial page load. However, once loaded, most analyses can be performed without further network requests. We’re exploring options for full offline support in the future.
