End User License Agreement

Last updated: 14 June 2026

Summary: Proxyma is licensed per device, not sold. You may install and use the software on the number of devices permitted by your license tier. You may not redistribute, sublicense, reverse-engineer, or use Proxyma as a hosted service for third parties. Your documents and data never leave your own infrastructure.

1. Parties

This End User License Agreement (“EULA”) is a legal agreement between you (“Licensee” or “you”) and Le Sy Hau, an individual software developer based in Vietnam (“Licensor,” “we,” or “us”), for the use of the Proxyma software application and all associated documentation files (collectively, the “Software”).

By downloading, installing, copying, or otherwise using the Software, you agree to be bound by the terms of this EULA. If you do not agree, do not install or use the Software.

2. License Tiers and Scope

The Software is available under the following tiers. The rights granted to you depend on which tier you have activated:

Community — Free of charge, unlimited in time. You may install and use the Software on one device. No License Key is required.
Professional — One-time purchase per device. You may install and use the Software on one device, with access to corporate source connectors. A License Key is required.
Enterprise — Custom pricing for organisations. Terms negotiated separately; a signed order form supplements this EULA.

“Device” means a single physical or virtual machine on which the Software process runs. Installing the same binary on a second device requires a separate license for that device, unless your tier explicitly permits multiple devices.

3. Grant of License

Subject to your compliance with this EULA and, where applicable, payment of the applicable fee, we grant you a limited, non-exclusive, non-transferable, non-sublicensable license to:

Install the Software on the permitted number of devices.
Use the Software for your own internal business or personal purposes.
Make one archival copy of the installer solely for backup purposes.

4. Restrictions

You may not:

Redistribute, resell, sublicense, rent, lease, or lend the Software or any License Key to any third party.
Offer the Software as a hosted or managed service to third parties (SaaS use requires a separate Enterprise agreement).
Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the Software, except to the extent expressly permitted by applicable law.
Remove, alter, or obscure any proprietary notices in the Software.
Use the Software to develop a competing product or service that replicates its core functionality.
Transfer your license to another person or entity without our prior written consent.

5. License Keys and Activation

The Professional and Enterprise tiers require a License Key delivered after purchase. You must keep your License Key confidential and must not share it with persons outside your licensed user count. If you believe your License Key has been compromised, contact us immediately at [email protected].

We reserve the right to revoke a License Key that has been shared in violation of this EULA without issuing a refund.

6. Ownership and Intellectual Property

The Software is licensed, not sold. We retain all right, title, and interest in and to the Software, including all intellectual property rights. This EULA does not grant you any rights to our trademarks, service marks, or logos.

Your documents, data, and knowledge sources remain entirely your property. The Software processes them locally on your infrastructure and does not transmit them to us or any third party.

7. Updates and New Versions

We may release updates, patches, or new versions of the Software. Community tier users receive updates at our discretion. Professional license holders are entitled to all minor and patch updates within the major version purchased; major version upgrades may be offered at a discounted upgrade price. Enterprise update entitlements are defined in the applicable order form. We have no obligation to provide updates indefinitely.

8. Disclaimer of Warranties

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 NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE OR UNINTERRUPTED.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THIS EULA OR THE USE OF THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL CUMULATIVE LIABILITY TO YOU SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE MONTHS PRECEDING THE CLAIM. IF YOU PAID NOTHING (COMMUNITY TIER), OUR TOTAL LIABILITY IS LIMITED TO USD 50.

10. Termination

This EULA is effective until terminated. It terminates automatically if you breach any of its terms. Upon termination you must cease all use of the Software and destroy all copies in your possession. Sections 4, 6, 8, 9, and 11 survive termination.

Termination of this EULA does not entitle you to a refund except as required by applicable consumer-protection law.

11. Governing Law

This EULA is governed by the laws of Vietnam, without regard to conflict-of-law principles. Any dispute arising out of or relating to this EULA shall be resolved in the courts of Vietnam. If you are a consumer in a jurisdiction whose laws provide stronger protections, those protections are not waived by this clause.

12. Changes to This EULA

We may update this EULA from time to time. The revised version will be posted at proxyma.ai/eula with a new “Last updated” date. Continued use of the Software after the updated EULA is posted constitutes your acceptance of the changes.
