Questions
Is a drawn signature legally valid?+
In most jurisdictions an electronic signature is valid for ordinary agreements. Check local rules for notarised documents.
Are my files uploaded anywhere?+
No. Every PDFOnCall tool runs inside your browser, so the file never leaves your device. That is also why it finishes in seconds instead of waiting in an upload queue.
