At KraftLines, your data never leaves your computer. We believe in tools that respect your workflow and your privacy.
Every coordinate, dimension, and configuration you input into our tools is processed locally in your browser. We don't have a database of your designs because we don't need one.
You shouldn't have to create an identity just to print a piece of graph paper. KraftLines is accessible instantly, no login, no email harvest, no barriers.
We don't use tracking pixels, invasive analytics, or third-party cookies. We are a utility, not an advertising platform. Your browsing habits are your business.
Our code is built on standard web technologies that are easily inspectable. There are no hidden backdoors or data exfiltration scripts. What you see is what you get.
Our engineering architecture is audited to ensure absolute zero-logging of user-generated design vectors.
Storage Logic
We utilize individual Blob URLs created via `URL.createObjectURL(blob)` for PDF spawning. These exist only in your RAM and are revoked immediately after delivery.
Network Logic
No tracking pixels or third-party CRM scripts are embedded. Every function executed on this site is a static asset delivery.
This tool is developed and maintained by the KraftLines technical team, specializing in sub-pixel vector geometry and industrial-grade PDF rendering. Each calculation is verified against ISO 216 and ANSI Y14.1 global engineering standards to ensure prints are accurate to the millimeter.
