Privacy Policy

CSV Graph (csv.qingyanglabs.com) is a free browser-based tool for converting CSV data into charts. This policy explains what data we collect, how it is used, and what choices you have.

When you paste or upload CSV data into the tool, the data is processed entirely in your browser. Your CSV content is never sent to our servers, stored in any database, or shared with any third party. All parsing, chart rendering, and file export happen locally on your device.

Like most websites, we may collect basic usage data through analytics services to understand how the site is used and to improve the product. This may include:

• Pages visited and time spent on each page
• Browser type, operating system, and screen resolution
• Referring URL and general geographic region
• Anonymized interaction events (e.g. chart exports, file uploads)

This data is aggregated and does not include your CSV content or any personally identifiable information.

We may use essential cookies for site functionality and analytics cookies to measure usage. Analytics cookies are provided by third-party services such as Google Analytics. You can disable cookies through your browser settings at any time.

The site may use the following third-party services:

• Google Analytics — for anonymous usage statistics. See the Google Privacy Policy.
• Google Fonts — to load the Inter typeface. See the Google Fonts Privacy FAQ.

We do not sell, rent, or share any user data with advertisers or data brokers.

The service is not directed at children under the age of 13. We do not knowingly collect personal information from children.

We may update this policy from time to time. Changes will be reflected on this page with an updated revision date. Continued use of the site after changes constitutes acceptance of the revised policy.
