Frequently Asked Questions

Is my data ever uploaded to the cloud?

By default, no. DataOlllo processes everything locally on your device.
If you enable AI features, you can choose between two sharing modes:
• Masked sample mode (default): Metadata and a small sample of rows are sent, but all sample data is masked. No raw data leaves your device.
• Raw sample mode (optional): Metadata and a small sample of rows are sent without masking to improve AI analysis. You will always see a Security Warning before enabling this mode.
You stay in full control of what is shared at all times.

How big a file can I open?

There is no artificial size limit.
Users have successfully opened:
• small files (KB–MB)
• large datasets (GB-level)
Your actual limit depends only on your machine’s memory.

Do I need to know code or formulas?

Nope — everything is point-and-click.
AI can help clean, transform, and analyze your data without writing code.
