WriteLang / 쓰면영어 End User License Agreement

Updated: 2026-09-08 · Effective date: First public beta release (date not yet set) · 한국어

1. Parties and beta scope

This agreement covers the first Windows public beta of WriteLang, known in Korea as 쓰면영어, provided by an individual developer without a registered business (the “Developer”). It is free through Microsoft Store or an official zip distribution, with no accounts, server-based sync, or payments. Any later macOS release or paid service will have its actual scope and terms disclosed separately. Contact: hello@writelang.com.

These terms must be available before installation or use. Installing or using the app after reviewing these terms accepts these conditions of use. If you do not accept them, stop installation/use and remove the app. This is not consent to personal-data collection. The first beta is for people aged 14 and older. Minors must obtain any parent/legal-guardian consent required by applicable law.

2. License and rights

The Developer grants you a free, non-exclusive license to install the app on supported devices you own or lawfully control and use it for personal or work purposes. The app is licensed, not sold. Rights in the Developer's code, branding and other materials remain with their owners. Without separate permission or legal authority, you may not sell or sublicense the Developer's app or misrepresent it as your official product.

All rights not expressly granted are reserved. Without separate written permission, you may not modify, copy or distribute (including free redistribution), sell, rent or sublicense the Developer’s app or proprietary code, or use the Developer’s trademarks. This does not prohibit copying necessary for permitted installation, operation and backup, acts protected by applicable law, or rights under the third-party licenses below.

Each third-party open-source component and model is governed by its own license, which takes priority for that component. This agreement does not restrict use, copying, modification or redistribution permitted by those licenses, or rights such as reverse engineering allowed by law. The Developer claims no ownership of your input or output, but does not guarantee that output is copyrightable, exclusive, or free of third-party rights. You must have authority to process your input and verify that your use of output is lawful.

3. Models and third-party terms

At first launch, you separately download a model from Hugging Face to run on your device. Google currently identifies Gemma 4 E4B QAT q4_0 as subject to the Gemma 4 Apache License 2.0. Future Qwen3.5 availability will be checked against the actual model's Apache 2.0 license. llama.cpp uses the MIT license.

You must comply with the licenses applicable to the models you actually use. The Gemma Terms of Use and Gemma Prohibited Use Policy are also available for reference. The current Terms page directs Gemma 4 to a separate license; this agreement does not automatically impose older Gemma models' policy pass-through obligations on Gemma 4. If a future offered model is governed by those terms, applicable restrictions and downstream notice requirements will be clearly provided before its use. See Third-Party Notices for licenses and restricted-use information.

4. Beta limitations and checking results

The beta may mistranslate, omit or add meaning, replace text incorrectly, stop working, lose files, or have device compatibility problems. Check results before replacing or sending text in another app and back up important materials. AI output does not replace professional legal, medical or financial judgment. We do not promise a particular quality, speed, supported device, final release date or ongoing free updates. The Developer may change or discontinue beta features, with advance notice where practicable.

5. No warranty

To the extent permitted by applicable law, the app and output are provided “as is” and “as available.” The Developer disclaims express or implied warranties of accuracy, merchantability, fitness for a particular purpose, non-infringement, uninterrupted operation or freedom from errors. Warranties and user rights that cannot legally be excluded remain intact.

6. Limitation of liability

To the extent permitted by applicable law, the Developer limits liability for indirect, special or consequential loss or lost profits related to use of the app. Neither this limitation nor the warranty disclaimer applies to liability that cannot lawfully be excluded or limited, including intentional misconduct or gross negligence by the Developer, death or personal injury, and violations of data-protection duties where non-excludable. Liability is not capped at zero merely because the app is free. Mandatory consumer rights and remedies remain intact.

7. Privacy and optional feedback

Processing is described in the Privacy Policy. Accepting this agreement does not authorize optional feedback transmission. Feedback is submitted only when you write it and press Send. Not submitting or requesting lawful suspension/deletion does not reduce translation or correction functionality. Translation input/results are not collected for quality improvement. User-selected final text-free ratings are transmitted separately; their fields, grounds and choices are described in the Privacy Policy. Publishing the privacy policy does not constitute consent.

8. Termination, changes and disputes

You may stop use and remove the app at any time. For a material breach, the Developer may terminate your license to the Developer's app after explaining the reason and providing a reasonable opportunity to remedy it. Third-party licenses govern their own survival and termination. Changes to these terms will be announced with their effective date and will not retroactively remove accrued rights. Material changes requiring separate consent will follow a lawful acceptance procedure.

Applicable Microsoft Store terms also govern acquisition through that store. This agreement governs app use between you and the Developer and is interpreted consistently with mandatory law and applicable Store terms. Governing law and jurisdiction follow applicable law without excluding mandatory protections or statutory jurisdiction in your place of residence. No mandatory arbitration, class-action waiver or exclusive foreign court is required. If a term is invalid, the remainder continues to the extent allowed by law. Differences between the Korean and English texts are interpreted consistently with mandatory law and user protection.
