### Permitted Purpose
A Permitted Purpose is any purpose other than a Competing Use.
A Competing Use means making the Software available to any party (on a stand

4. in connection with professional services that you provide to a licensee using
the Software in accordance with these Terms and Conditions, including
professional services to deploy the Software or host the Software for the
licensee.
### Limitations
You must not move, change, disable or circumvent the license key functionality
of the Software or modify any portion of the Software protected by the license
key to:
- enable access to the protected functionality without a valid license key or
- remove the protected functionality.
### Patents
To the extent your use for a Permitted Purpose would necessarily infringe our
patents, the license grant above includes a license under our patents. If you
make a claim against any party that the Software infringes or contributes to the
infringement of any patent, then your patent license to the Software ends
immediately.
### Redistribution
The Terms and Conditions apply to all copies, modifications and derivatives of
the Software.
If you redistribute any copies, modifications or derivatives of the Software,
then (A) you must include a copy of or a link to these Terms and Conditions and
not remove any copyright notices provided in or with the Software and (B) you
may not impose any further restrictions on the exercise of the rights granted or
affirmed under this License. For example, you may not impose a license fee,
royalty, or other charge for exercise of rights granted under this License.
### Disclaimer
THE SOFTWARE IS PROVIDED "AS IS" AND WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF FITNESS FOR A PARTICULAR
PURPOSE, MERCHANTABILITY, TITLE OR NON-INFRINGEMENT.
IN NO EVENT WILL WE HAVE ANY LIABILITY TO YOU ARISING OUT OF OR RELATED TO THE
SOFTWARE, INCLUDING INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN
IF WE HAVE BEEN INFORMED OF THEIR POSSIBILITY IN ADVANCE.
### Trademarks
Except for displaying the License Details and identifying us as the origin of
the Software, you have no right under these Terms and Conditions to use our
trademarks, trade names, service marks or product names.

the GNU General Public License version 3 (GPL-3.0), effective on the fourth
anniversary of the date we make the Software available.
