Zero data retention The name you send is turned into a signature in memory and returned in the same response. It is never written to a database, a log or a disk, and neither is the image. The only thing Handsign keeps is a counter for your quota: when a signature was made, with which style and size. Details in the Terms
How it works A handwriting model writes the name stroke by stroke, sixteen times in parallel on the GPU, and keeps the cleanest take. The signature is then styled (initial, trailing letters, underlines, loops) and inked with the pen of your choice, with a line width that follows the speed of the gesture.
Options Seven styles (classic, executive, flowing, sharp, minimal, loop, scribble), six pens (ballpoint, gel, fineliner, fountain, marker, pencil), any ink color, transparent or colored backgrounds, and four widths: S 128 px, M 256 px, L 512 px and XL 1024 px.
