Privacy

Form Fill runs entirely in your web browser. When you open a PDF, type into its fields, or add a signature image, the file and the image are read and processed locally on your device.

Your PDFs and signature images are not uploaded to our server or to any third party.
Nothing you enter is stored after you close or reload the page. Signatures you upload are kept in memory only for the current session.
The completed PDF is generated in your browser and saved directly to your device.
Our web server keeps standard access logs (IP address, time, requested page, browser type) for security and operations. These logs never contain your documents.
We do not use advertising or tracking cookies.

Signatures

Placing an image of a signature on a document creates a visual signature, not a cryptographic digital signature. Whether it is acceptable for a particular document depends on the requirements of the person or organisation receiving it.

Open-source software

Form Fill is built with PDF.js (Apache License 2.0) and pdf-lib (MIT License). See the third-party licenses.
