Free Extensions
All free TDCLab extensions are open-source software released under the GNU General Public License version 2 or later (GPL-2.0+).
You are free to use, modify, and redistribute free TDCLab extensions in accordance with the terms of the GPL. The source code for every free extension is included in the install package.
Pro Extensions and Subscriptions
Pro releases are commercial software. Access to Pro releases requires an active annual subscription purchased through this site.
Your Pro subscription grants you a personal, non-transferable licence to:
- Download and install Pro releases on websites you own or administer.
- Receive authenticated automatic updates via the Joomla Update Manager for the duration of your subscription.
Your licence key is issued at the time of purchase and is tied to your subscription. It is used to authenticate downloads and updates. Keep it safe — do not share it publicly.
Pro subscription licences are not GPL. Redistribution of Pro releases is not permitted.
Your access to Pro releases continues for as long as your subscription is active. If your subscription lapses, previously downloaded versions may continue to be used but you will not receive further updates.
Third-Party Libraries
Some extensions bundle third-party libraries. All bundled libraries are licensed under terms compatible with the GPL, including:
- LGPL-2.1 or later — GNU Lesser General Public License
- MIT — MIT License
- Public Domain
Extensions that include third-party libraries ship with a LICENSES-third-party.txt file listing each library, its version, author, licence, and project URL.
