FAQ

How do these data cleaning tools process my information?

When you use a tool, your data is sent from your browser to Elysia Tools servers for processing. This ensures high performance for complex operations without needing local software installation.

Is my data stored on your servers?

No. Text inputs are never stored. For tools requiring file uploads, all files are automatically and permanently deleted from our servers 6 hours after processing.

Can I clean datasets without installing plugins?

Yes, all 6 data cleaning tools operate entirely through your web browser. Processing is handled on our backend infrastructure, so you do not need to install any additional software or browser extensions.
