### License Versioning Policy

This License is version 3.3 of the TELEMT License.
Each version of the Software is licensed under the License that accompanies its corresponding source code distribution.

Future versions of the Software may be distributed under a different version of the TELEMT Public License or under a different license, as determined by the Telemt maintainers.

Any such change of license applies only to the versions of the Software distributed with the new license and SHALL NOT retroactively affect any previously released versions of the Software.

Recipients of the Software are granted rights only under the License provided with the version of the Software they received.

Redistributions of the Software, including Modified Versions, MUST preserve the copyright notices, license text, and conditions of this License for all portions of the Software derived from Telemt.

Additional terms or licenses may be applied to modifications or additional code added by a redistributor, provided that such terms do not restrict or alter the rights granted under this License for the original Telemt Software.

Nothing in this section limits the rights granted under this License for versions of the Software already released.

### Definitions

For the purposes of this License:

**"Software"** means the Telemt software, including source code, documentation, and any associated files distributed under this License.

**"Contributor"** means any person or entity that submits code, patches, documentation, or other contributions to the Software that are accepted into the Software by the maintainers.

**"Contribution"** means any work of authorship intentionally submitted to the Software for inclusion in the Software.

**"Modified Version"** means any version of the Software that has been changed, adapted, extended, or otherwise modified from the original Software.

**"Maintainers"** means the individuals or entities responsible for the official Telemt project and its releases.

### 1 Attribution

Redistributions of the Software, in source or binary form, MUST RETAIN:

- the above copyright notice;
- this license text;
- any existing attribution notices.

### 2 Modification Notice

If you modify the Software, you MUST clearly state that the Software has been modified and include a brief description of the changes made.

Modified versions MUST NOT be presented as the original Telemt.

### 3 Trademark and Branding

This license DOES NOT grant permission to use the name "Telemt", the Telemt logo, or any Telemt trademarks or branding.

Redistributed or modified versions of the Software MAY NOT use the Telemt name in a way that suggests endorsement or official origin without explicit permission from the Telemt maintainers.

Use of the name "Telemt" to describe a modified version of the Software is permitted only if the modified version is clearly identified as a modified or unofficial version.

Any distribution that could reasonably confuse users into believing that the software is an official Telemt release is prohibited.

### 4 Binary Distribution Transparency

If you distribute compiled binaries of the Software, you are ENCOURAGED to provide access to the corresponding source code and build instructions where reasonably possible.

This helps preserve transparency and allows recipients to verify the integrity and reproducibility of distributed builds.

### 5 Patent Grant and Defensive Termination Clause

Each contributor grants you a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable patent license to:

- make,
- have made,
- use,
- offer to sell,
- sell,
- import,
- and otherwise transfer the Software.

This patent license applies only to those patent claims necessarily infringed by the contributor’s contribution alone or by combination of their contribution with the Software.

If you initiate or participate in any patent litigation, including cross-claims or counterclaims, alleging that the Software or any contribution incorporated within the Software constitutes patent infringement, then **all rights granted to you under this license shall terminate immediately** as of the date such litigation is filed.

Additionally, if you initiate legal action alleging that the Software itself infringes your patent or other intellectual property rights, then all rights granted to you under this license SHALL TERMINATE automatically.

### 6 Contributions

Unless you explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Software shall be licensed under the terms of this License.

By submitting a Contribution, you grant the Telemt maintainers and all recipients of the Software the rights described in this License with respect to that Contribution.

### 7 Network Use Attribution

If the Software is used to provide a publicly accessible network service, the operator of such service SHOULD provide attribution to Telemt in at least one of the following locations:

- service documentation;
- service description;
- an "About" or similar informational page;
- other user-visible materials reasonably associated with the service.

Such attribution MUST NOT imply endorsement by the Telemt project or its maintainers.

### 8 Disclaimer of Warranty and Severability Clause

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

IF ANY PROVISION OF THIS LICENSE IS HELD TO BE INVALID OR UNENFORCEABLE, SUCH PROVISION SHALL BE INTERPRETED TO REFLECT THE ORIGINAL INTENT OF THE PARTIES AS CLOSELY AS POSSIBLE, AND THE REMAINING PROVISIONS SHALL REMAIN IN FULL FORCE AND EFFECT.
