BUILT FOR REAL PAPERWORK Your signature is flattened into the page itself, so what you see is exactly what your bank, landlord or HR portal sees. There are no live annotations to render differently in Preview, Acrobat or a web viewer. Page size is preserved too: Letter stays Letter, A4 stays A4, and a landscape scan stays landscape. YOUR DOCUMENTS STAY ON YOUR DEVICE No accounts. No ads. Your PDFs, signatures and saved details are stored on your device and are never uploaded. Sign Any PDF does share product usage analytics, such as which features are used, to help improve the app. The screens that show your documents, signatures and saved details are excluded, and you can switch analytics off in Settings. Full privacy policy: https://mackgrissom.github.io/signfast-site/privacy.html GOOD TO KNOW Sign Any PDF places visible signatures and text on a document. It does not create certificate-based digital signatures, and does not verify anyone else's. SUPPORT Email mcintyregrissom@gmail.com, or tap Settings then Email support.
