Atlas Beta License & Terms of Use

1. Beta License Grant

Subject to these terms, Patrik Papšo (“Author”) grants you a personal, non-exclusive, non-transferable, revocable, royalty-free license during the public beta period to download, install, and use the compiled Atlas software (“Software”) on Windows devices that you own or control, for personal, educational, or commercial software development.

Atlas is currently free to use during beta. Future major releases or post-beta versions may be offered under updated license or pricing terms; any such changes will not apply retroactively to versions already installed unless you choose to upgrade under the new terms.

2. Restrictions

Atlas is proprietary, closed-source software. Except as expressly permitted by applicable law or by the licenses of bundled third-party open-source components, you may not:

redistribute, sell, rent, lease, or sublicense the Software;
reverse engineer, decompile, or disassemble the Software; or
remove or alter any copyright, trademark, or license notices included in the Software.

3. Your Code, Local Data, and External Tools

Your source code, workspace documents, code annotations, transcripts, CPU profiles, and settings remain your property and are stored locally on your machine (or in a synced folder you explicitly configure).
Atlas connects to external coding agents (ACP), language servers (such as clangd), version control clients (Git, Perforce), build tools (Unreal Engine, MSBuild), debuggers, and profilers that you configure or authorize. Your use of those third-party tools and services is governed by their respective terms and privacy policies.
When you apply proposed edits, edit files in the Code panel, or enable Power User build, debug, or profiling capabilities, the Software and your project’s own tools execute on your machine with your user permissions. You are responsible for reviewing proposed changes and maintaining backups or version control of your workspaces.

4. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. BETA RELEASES AND PREVIEW BUILDS MAY CONTAIN BUGS OR INCOMPATIBILITIES AND MAY MODIFY LOCAL APPLICATION STORAGE IN WAYS OLDER VERSIONS CANNOT READ.

5. Limitation of Liability

IN NO EVENT SHALL THE AUTHOR 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, INCLUDING WITHOUT LIMITATION ANY LOSS OF DATA, WORKSPACE CORRUPTION, OR BUSINESS INTERRUPTION, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
