The PDF generation service is an internal service so its security is covered by that of PredicSis.ai.
You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. However, you cannot prevent saving copies of a PDF. The copies have the same restrictions as the original PDF. To configure this click here
