FAQ

How are my data analysis tasks processed?

While you interact with the tools in your browser, all data processing is performed on Elysia Tools servers. This allows for efficient handling of complex data operations without consuming your local system resources.

Is my data kept secure during analysis?

Yes. We do not store text inputs, and any files uploaded for analysis are automatically deleted from our servers after 6 hours. No data is permanently retained.

Do I need to install any software to use these tools?

No software installation is required. You can access all 24 data analysis tools directly through any modern web browser, with all computations handled by our backend infrastructure.
