Terms of Service

Last updated: 4 August 2026

1. About Proxyma and These Terms

Proxyma is developed and maintained by Le Sy Hau, an individual software developer based in Vietnam. All references to “we,” “us,” or “the Developer” in these Terms refer to this individual person.

By downloading, installing, or using Proxyma, you (“Customer” or “you”) agree to these Terms of Service (“Terms”). If you do not agree, do not use Proxyma.

These Terms cover the Proxyma software you download and run yourself. If you create an account on a Proxyma Server deployment that we host — including the demonstration instance at enterprise-demo.proxyma.ai — the Terms of Service and Privacy Policy served inside that deployment govern that account, and you are asked to accept them explicitly when the account is created.

2. Definitions

3. License Grant

Subject to these Terms and, where applicable, payment of the applicable fee, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use Proxyma on the number of concurrent instances permitted by your Tier, as described on the pricing page at proxyma.ai.

The Community tier is provided free of charge for an unlimited time. It requires no License Key and is subject to the feature restrictions described on the pricing page.

4. Purchases and Billing

The Community tier is provided entirely free of charge. No purchase, subscription, or License Key is required.

The Personal and Professional tiers are sold as a one-time purchase per device. All such purchases are processed by Lemon Squeezy (lemonsqueezy.com), which acts as our authorised reseller and Merchant of Record. They take the payment, calculate and remit any applicable VAT or sales tax, issue your invoice, and appear as the merchant on your card statement. By purchasing, you also agree to Lemon Squeezy's Terms of Service. We do not see or store your payment information.

What a licence does not include

A licence does not include AI usage or AI credits. Proxyma needs an AI model to answer questions, and you supply it. You can run one locally at no additional cost, or connect a third-party provider (Anthropic, OpenAI, DeepSeek, Mistral, Azure OpenAI or Google) using your own account and API key. Where you choose a third-party provider, that provider bills you directly at its own rates and under its own terms. We are not a party to that relationship, do not resell its capacity, and have no control over its pricing or availability. No part of your licence fee is applied to it.

Enterprise pricing is available on request and is governed by a separate written agreement.

5. Refunds and Right of Withdrawal

The Community tier is free; no refund is necessary or possible.

14-day refund, anywhere in the world. If Proxyma is not right for you, email [email protected] within 14 days of purchase and we will refund it in full. You do not need to give a reason.

We ask that you try the free Community edition first. It is not a time-limited demo — it will tell you whether Proxyma suits how you work before you spend anything.

Before requesting a refund, please release the licence in Settings → Licence → Release. A refunded licence is revoked and may not continue to be used; continuing to use the Software after a refund is a breach of the End User License Agreement.

Refunds are processed by Lemon Squeezy as Merchant of Record, under their Buyer Terms, which also govern chargebacks.

This policy is in addition to your rights under local consumer law — including the statutory right of withdrawal for consumers in the European Union and the United Kingdom, and the consumer guarantees under Australian Consumer Law. Nothing here limits any right that cannot be limited by agreement.

6. Intellectual Property

Proxyma, the Proxyma name, and all associated intellectual property are owned by Le Sy Hau. These Terms do not grant you any right to use the Proxyma name or logo beyond what is necessary to describe your use of the Software.

You retain full ownership of all documents, files, and data you process using Proxyma. Proxyma processes your data locally on your own infrastructure; we acquire no rights to your content.

7. Prohibited Uses

You may not:

8. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE, UNINTERRUPTED, OR FREE OF HARMFUL COMPONENTS.

Some jurisdictions do not allow the exclusion of implied warranties. If the law in your country requires implied warranties, they are limited to the minimum warranty period permitted by that law.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR LOSS OF PROFITS, DATA, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SOFTWARE.

OUR TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS SHALL NOT EXCEED THE FEES YOU PAID IN THE 12 MONTHS PRECEDING THE CLAIM. If you paid nothing (Community tier), our total liability is limited to USD 50.

Nothing in these Terms limits or excludes liability that cannot be excluded by applicable mandatory law, including consumer protection laws and product liability laws in your country of residence.

10. Governing Law and Disputes

These Terms are governed by the laws of the Socialist Republic of Vietnam, without regard to conflict-of-law principles.

If you are a consumer located in the European Economic Area, the mandatory consumer protection laws of your country of residence also apply, and you may bring proceedings before the courts of your country of residence.

For any dispute, please contact us first at [email protected]. We will make a genuine effort to resolve the issue informally before any formal proceedings.

The European Commission provides an online dispute resolution platform for EU consumers at: ec.europa.eu/consumers/odr/.

11. Changes to These Terms

We may update these Terms from time to time. The “Last updated” date at the top reflects the most recent revision. Continued use of Proxyma after such notice constitutes your acceptance of the updated Terms.
