Sign is a local image utility for placing handwritten signature marks on selected JPG or PNG photos and saving new JPG copies.
Selected images and signature marks are processed on the device. Sign does not upload selected files or signature drawings to our servers.
Sign may show ads through Google AdMob. Google Mobile Ads may process data for ad serving, fraud prevention, diagnostics, analytics, and platform operation.
