Privacy by architecture.

Your files stay on your device

Glassline processes files inside your browser with WebAssembly. CSV, TSV, XLSX, query results, filters, and exports are not sent to us or to any third party. Closing or refreshing the tab clears the active workspace.

What the site stores

A service worker may cache the application code and original illustration on your device so the interface can open offline. It does not cache your data files or query results. You can remove this cache through your browser’s site-data controls.

Telemetry and third parties

Glassline contains no analytics, advertising, trackers, third-party scripts, or remotely loaded fonts. Standard infrastructure access logs may temporarily contain a request time, requested path, IP address, and browser user-agent for reliability and abuse prevention.

Your control

Do not open a file on a shared device unless you trust the browser session. To clear the active file, close the tab. For privacy questions, contact the operator through sociobot.in.
