Terms of Service
The ground rules.
Last updated: 8 July 2026
1. Acceptance
These Terms of Service ("Terms") govern your use of the EdgeLingo mobile application (the "App"), provided by EdgeLingo ("we", "us"). By downloading or using the App, you agree to these Terms. If you do not agree, please do not use the App.
2. License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for your own personal, non-commercial language learning. You may not copy, resell, sublicense, or commercially exploit the App, or attempt to reverse-engineer, decompile, or extract its bundled models except to the extent permitted by applicable law or the relevant open-source licenses.
3. The App is a learning aid
EdgeLingo uses on-device AI to help you practice a language. AI-generated conversations, corrections, translations, and explanations may be inaccurate or incomplete. The App is a study aid, not professional, certified, or authoritative language instruction, and should not be relied upon for high-stakes decisions. Please use your own judgment.
4. Your content
Content you create in the App (conversations, custom scenarios, saved phrases, photos you attach) is stored only on your device. You are responsible for that content and for any photos you choose to use. Because we do not receive your content, we do not moderate, back up, or have access to it.
5. Acceptable use
You agree not to use the App to create unlawful, harmful, or abusive content, to infringe others' rights, or in any way that violates applicable law. You are responsible for your own use of the App's AI features.
6. Model downloads & availability
The App downloads AI model files over the internet on first use. We aim to keep these available but do not guarantee uninterrupted availability of the download servers. Once downloaded, the App's core features work offline.
7. Intellectual property
The App, its name, and its design are owned by us. The App incorporates open-source AI models — including Google's Gemma, and the Kokoro and WhisperKit models — which remain the property of their respective authors and are used under their open-source licenses (Apache 2.0 and MIT). Attributions are provided in the App.
8. No warranty
The App is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy, or non-infringement, to the fullest extent permitted by law.
9. Limitation of liability
To the fullest extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss arising out of your use of, or inability to use, the App.
10. Changes
We may update these Terms from time to time. Continued use of the App after changes take effect constitutes acceptance of the revised Terms. Material changes will be posted here with a new date.
11. Governing law
These Terms are governed by the laws of Taiwan (R.O.C.), without regard to its conflict-of-laws rules, except where mandatory local consumer-protection law of your place of residence applies.
