Privacy Policy

Last updated: February 2026

Overview

CSV Plot Studio is a client-side data visualization tool. Your data never leaves your browser. We are committed to protecting your privacy and ensuring your data remains under your control.

Data Processing

All CSV file processing, chart generation, and data analysis happens entirely within your web browser using Web Workers. No data is uploaded to any server. Your files are parsed locally using the PapaParse library and visualized using Plotly.js.

Local Storage

We use your browser's localStorage to persist chart configurations and recent dataset metadata. This data is stored only on your device and can be cleared at any time through your browser settings.

  • Chart configurations are saved so they can be restored when you re-upload the same dataset.
  • Recent uploads metadata (file name, row count, column count) is stored for convenience. The actual file data is not persisted.

No Analytics or Tracking

CSV Plot Studio does not use cookies, analytics services, or any form of user tracking. We do not collect personal information, usage statistics, or behavioral data.

Third-Party Services

This application does not communicate with any third-party services. All functionality is self-contained within the browser. No external API calls are made with your data.

Data Security

Since your data never leaves your browser, it is protected by your browser's built-in security mechanisms. We recommend keeping your browser up to date to benefit from the latest security features.
