Terms of License Authorization

These Terms of License Authorization supplement the General Terms of Use and specifically govern the scope, management, and restrictions of the software licenses purchased from DVDFab.cn.

1. License Definitions

  • Single-User License (1-PC): Unless otherwise stated, a standard license grants you the right to install and use the software on one (1) computer only.
  • Multi-Computer Authorization: This is an optional add-on or a specific license type that allows the software to be authorized on multiple computers (e.g., 3 PCs, 5 PCs) simultaneously under a single account.
  • Platform Specificity: Licenses are platform-specific. A license purchased for Windows cannot be used on macOS, and vice versa, unless explicitly purchased as a dual-platform bundle.

2. Authorization Management & Deauthorization

You can manage your device authorizations through the software client or, with limitations, through the online User Center.

  • Client-Side Deauthorization (Recommended): You may deauthorize a computer directly within the software client at any time. There is no limit to the number of times you can deauthorize and re-authorize devices using the client interface, provided you do not exceed your total concurrent device limit.
  • User Center Deauthorization (Web-Based): To prevent abuse, strictly limited deauthorization options are available via the online User Center (for situations where you cannot access the computer, e.g., hardware failure or loss):
    • 1-PC License: You may deauthorize your current device via the User Center only once per year.
    • Multi-Computer License: Deauthorization via the User Center is not supported for multi-computer licenses. You must manage authorizations directly on the client devices.

3. Purchase Restrictions & Non-Stackability

  • Non-Stackable: Multi-Computer Authorizations are not stackable. If your current license plan already includes multi-device access (whether purchased or received as a bonus), you cannot purchase additional Multi-Computer Authorizations for the same product to increase the limit further.
  • No Duplicate Purchase: You cannot purchase a Multi-Computer Authorization if the system detects that your account already possesses the maximum allowable authorization capacity for that specific product.

4. Home & Personal Use Only

  • Household Sharing: Multi-Computer Authorizations are intended strictly for use within a single household.
  • Prohibition on Sharing: You may not share your account credentials or license keys with individuals outside your household.
  • Commercial Use Ban: Licenses are for personal, non-commercial use only. Using these licenses to provide services to others for a fee is strictly prohibited.

5. Updates and Upgrades

  • Subscription Licenses: You are entitled to free updates and major upgrades only while your subscription is active.
  • Lifetime Licenses: You are entitled to free updates and major upgrades for the lifetime of the product, subject to the product’s continued availability and support.
