Why Plico

Plico is the answer to the question: “Is there a simple app to sign PDF documents?”

The key to that answer lies in the word “simple”: in this context, it takes on different shades of meaning depending on who needs to sign a document. Simple means “Easy to use”, Simple means “I don’t want to create yet another account on yet another online service that fills my inbox with spam”, Simple means “Free”, Simple means “My data is mine, and I want it to stay that way”, Simple means “I don’t want to turn on the printer that can’t print anyway because it’s out of magenta”.
