Graph Lines is designed to work without collecting your personal information.
The generator
- Every sheet is drawn in your web browser. Nothing you make is uploaded to Graph Lines or anyone else.
- Your last settings are kept in your browser’s local storage on your device, so they’re there next time. To remove them, clear this site’s data in your browser settings.
- When you copy a link, your settings are stored after the
#in the address. Browsers don’t send that part of an address to the server. - Files you download are saved directly to your device.
- The generator loads no fonts, scripts or other files from other services.
