Explore Excise PDFEach product explains what stays on your device, what can use a network, and what a connected service may receive. The current products keep their databases or documents local.
Calculations, limits, verification results, and failure states are visible. You should not have to take a percentage, a risk score, or a redaction result on faith.
All three products are one-time purchases. Desktop licences verify offline and installed versions keep working; Excise PDF also offers one Universal Purchase for Mac, iPhone, and iPad. Data and documents stay local.
