Terms of Service
The ground rules.
Last updated: 18 September 2026 (EdgeLingo 2.0)
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 — and, if you turn it on, cloud 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. We do not moderate, back up, or keep it. If you turn on Cloud AI, the text needed for each request — and a photo, if you agree to send one — passes through our servers to our AI provider to generate a reply and is not stored by us, as described in the Privacy Policy.
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. Cloud AI
Cloud AI is an optional feature that is off until you turn it on. When it is on, conversations and other AI features are answered by Google's Gemini model through our servers.
- Included with your purchase. Cloud AI costs nothing extra — no subscription, no per-message fee, no account.
- Daily fair-use limit. Each purchase has a daily usage allowance for Cloud AI. When it is reached, the App keeps working with the on-device AI until the allowance resets the next day (UTC). We may adjust the allowance to keep the service sustainable for everyone.
- Availability. Cloud AI depends on an internet connection and on third-party services. We do not guarantee that it will always be available, and we may change, limit, suspend, or discontinue it. Whenever it is unavailable, the App continues to work with the on-device AI.
- Fair use. You may not use Cloud AI outside the App, automate requests, attempt to get around the daily limit, or use it in ways that violate Google's generative AI usage policies. We may suspend Cloud AI access for purchases used this way.
7. Model downloads & availability
Some AI model files, such as speech and voice packs for each language, are downloaded over the internet when first needed. 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.
Device requirements: the App runs a large AI model on your device and requires an iPhone with at least 6 GB of memory and iOS 26 or later. Compatible models include iPhone 12 Pro / 12 Pro Max, iPhone 13 Pro / 13 Pro Max, and every iPhone 14 or later model. iPhone 12, 12 mini, 13, 13 mini and iPhone SE models are not supported.
8. Purchases
The App is a one-time purchase made through Apple's App Store. Payment is processed by Apple; we do not receive or store your payment details. Prices may vary by region and may change for new purchases. Refunds are handled by Apple under the App Store's terms — you can request one at reportaproblem.apple.com. Once purchased, updates to the App — and Cloud AI while we offer it, as described in section 6 — are included at no extra charge.
9. Intellectual property
The App, its name, and its design are owned by us. The App incorporates open-source AI models, which remain the property of their respective authors and are used under their respective licenses. Attributions and license texts are provided in the App.
10. No warranty
The App, including Cloud AI, 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.
11. 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.
12. 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.
13. Governing law
These Terms are governed by the laws applicable in your country of habitual residence. Nothing in these Terms limits any rights you have under the mandatory consumer-protection laws of that country.
