🛡️ 100% In-Browser Privacy Guarantee

Privacy Policy & Security

We believe your corporate data, financial metrics, and confidential numbers belong exclusively to you.

1. Zero Server-Side Data Transmission

All data parsing (CSV, TSV, JSON, clipboard), mathematical scaling, chart rendering, quality linting, and export conversions (PNG, SVG, PDF, CSV, HTML) run exclusively inside your web browser's local memory.

When you paste spreadsheet numbers or drag a CSV file into the application, that data is never transmitted to our web servers, cloud APIs, analytics engines, or external storage providers.

2. Local Browser Storage (IndexedDB & LocalStorage)

When you save a chart or preserve a local draft, the chart document is written to your browser's private local storage (IndexedDB). This data remains strictly on your device and is never synchronized to an external cloud database. You can clear this data at any time by clearing your browser's site data.

3. Opt-in URL Fragment Sharing

When you use the "Share Link" feature, your chart state is compressed into the URL hash fragment (the part of the URL after the #chart=... symbol). Under internet communication standards (RFC 3986), URL fragments are evaluated exclusively on the client machine and are never sent to the web server in HTTP requests.

Notice: Anyone with whom you choose to share your compressed link will be able to decompress and view the chart data contained in that link.

4. No Tracking Cookies or Third-Party Pixels

We do not use advertising trackers, surveillance pixels, cross-site trackers, or third-party cookies.
