This document clarifies the subscription tiers, included feature sets, purchasing channels, and enterprise customization policies for our two endpoint data loss prevention solutions: USB Disk Security (Standard Edition) and PrivateDLP (Pro Edition). Both solutions adopt a Client/Server (C/S) architecture and support Windows-only endpoint deployment with centralized web-based policy management. This article distinguishes standard core security capabilities and advanced AI-powered enterprise features, explains public and enterprise-only purchasing rules, and details customizable enterprise-grade options for PrivateDLP tailored to business data security and compliance requirements.
This tutorial offers comprehensive step-by-step deployment instructions for installing and activating endpoint clients of USB Disk Security (Standard Edition) and PrivateDLP (Pro Edition) via EXE installation packages. Designed for individual evaluators, small team users and small-scale deployment administrators, it covers the entire operational process, including installer acquisition, local client deployment, web console account registration, free trial activation, paid license binding and post-deployment effect verification. The EXE installation package is tailored for single-device deployment and small-scale batch rollouts, requiring manual license configuration and console binding for each endpoint device. Both product editions adopt a unified EXE installation process and consistent client interface, with differentiated functional capabilities automatically enabled according to the activated license type. This guide is applicable to end users, IT support personnel and security administrators responsible for deploying the software on individual Windows terminals.
PrivateDLP (Pro‑edition upgraded from USB Disk Security) delivers enterprise‑grade data leak prevention, USB device governance, network access control, and AI‑powered workplace activity auditing for Windows endpoints. Every endpoint client maintains a local license tile on the main dashboard, allowing IT administrators to quickly verify activation state, expiry date, and understand device quota rules tied to license keys.
This article explains subscription renewal, upgrade and downgrade workflows for PrivateDLP and USB Disk Security, covering two customer groups: individual‑site purchasers via Stripe checkout links and enterprise customers. For users purchasing license keys through our official Stripe payment links, automatic recurring billing is enabled by default. Downgrade operations are generally not supported for these self‑service subscriptions; users may contact our team to perform upgrades, such as moving from Standard Edition to PrivateDLP Pro Edition, and a dedicated custom payment link will be provided. Enterprise customers for bulk deployment must reach our business email busdev@privatedlp.com for all renewal, upgrade and downgrade‑related requests. Proper subscription management ensures endpoints maintain an Active license status and keep full access to USB security, device control, network governance and AI‑powered DLP auditing capabilities.
This Refund Policy clearly defines the refund eligibility, valid period, application procedures, and exclusion terms for all users of USB Disk Security (Standard Edition) and PrivateDLP (Pro Edition). We provide a 30‑day money‑back guarantee for eligible self‑service subscriptions purchased via our official Stripe payment links. Downgrade and partial refund rules are not applicable to individual self‑service orders, while all refund requests for enterprise customized subscriptions must be submitted via official business email for manual review. This policy aims to standardize the refund process, protect legitimate user rights, and maintain standardized subscription service management.
