End User License Agreement
Last Updated: April 4, 2026
Introduction
This End User License Agreement ("EULA") is a legal agreement between you ("User") and Thang Pham, operating as TonesFly ("Licensor"), for the use of the TonesFly mobile application ("the App"). By installing or using the App, you agree to be bound by the terms of this EULA.
1. License Grant
The Licensor grants you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on any Apple-branded device that you own or control, subject to the Usage Rules set forth in the Apple Media Services Terms and Conditions.
2. License Restrictions
You may not:
- Copy, modify, or distribute the App or any portion of it
- Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the App
- Rent, lease, lend, sell, sublicense, or otherwise transfer rights to the App
- Remove, alter, or obscure any proprietary notices, labels, or marks on the App
- Use the App for any purpose that is unlawful or prohibited by this EULA
3. Intellectual Property
The App and all content therein — including but not limited to the user interface, design, graphics, audio processing technology, and code — are the intellectual property of Thang Pham or its licensors, protected by copyright, trademark, and other intellectual property laws. TonesFly™ and the TonesFly logo are trademarks of Thang Pham. This EULA does not grant you any rights to the Licensor's trademarks or service marks.
4. User-Uploaded Content
You retain ownership of audio files you upload to the App. By uploading content, you grant the Licensor a limited, non-exclusive license to process such content solely for the purpose of generating listening practice challenges for your personal use.
Audio is processed entirely on your device and never leaves it. Only text transcripts are sent to our servers for real-time enrichment processing. Our backend does not store or retain transcript content after processing. All lesson content remains on your device and in your iCloud account. Practice data is stored locally on your device.
You are solely responsible for ensuring you have the necessary rights to upload and use any audio content within the App.
5. Subscriptions & In-App Purchases
The App offers premium features through auto-renewable subscriptions. Free users can import audio and create lessons instantly on-device with Quick Listen — audio never leaves your device. Free users also receive a limited number of lifetime full-mode lessons with multi-section practice and Light Ups. After the free full-mode allowance is exhausted, users can continue with Quick Listen. Free Light Up access is also limited; after the initial allowance is used, free users can still preview a small number of Light Ups per full-mode lesson.
Premium unlocks unlimited full-mode lessons with multi-section practice and Light Ups (per-context word explanations in your language). Full-mode processing sends text transcripts to our servers for real-time AI enrichment. Our backend does not store or retain transcript content after processing; audio stays on your device.
All payments are processed by Apple through your Apple ID account. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current billing period. You can manage or cancel your subscriptions at any time through your device's Settings > [Your Name] > Subscriptions.
6. Privacy
Your use of the App is subject to our Privacy Policy, which describes how we collect, use, and protect your information — including imported audio and transcript data. You can review the Privacy Policy in the App settings.
7. Disclaimer of Warranties
The App is provided "as is" and "as available" without warranties of any kind. To the maximum extent permitted by applicable law, the Licensor disclaims all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant the accuracy of speech recognition or transcription results.
Nothing in this section excludes or limits liability for death, personal injury, fraud, or any other liability that cannot be excluded or limited under applicable law, including under EU, UK, or local consumer protection laws.
8. Limitation of Liability
To the maximum extent permitted by applicable law, in no event shall the Licensor be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising from or related to your use of or inability to use the App. The Licensor's total aggregate liability shall not exceed the amount you paid for the App or subscriptions in the 12 months preceding the claim.
This limitation does not apply to liability that cannot be excluded or limited under applicable law, including under the EU Consumer Rights Directive, UK Consumer Rights Act 2015, or equivalent local consumer protection legislation.
9. Termination
This EULA is effective until terminated. Your rights under this EULA will terminate automatically if you fail to comply with any of its terms. Upon termination, you must cease all use of the App and delete all copies from your devices. Uploaded content may be deleted upon account termination. Sections 3, 7, 8, and 10 survive termination.
10. Governing Law
This EULA shall be governed by and construed in accordance with the laws of the Socialist Republic of Viet Nam. Any disputes shall be resolved in the competent courts of Khanh Hoa province, Viet Nam.
If you are a consumer in the European Union, United Kingdom, or any jurisdiction with mandatory consumer protection laws, nothing in this section deprives you of the protection of the mandatory laws of your country of residence, and you may bring proceedings in your local courts.
11. Apple-Specific Terms
This EULA is between you and the Licensor only, not with Apple Inc. ("Apple"). The Licensor, not Apple, is solely responsible for the App and its content. Apple has no obligation to provide maintenance or support for the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any). Apple is not responsible for addressing any claims relating to the App or your use of it. Apple and its subsidiaries are third-party beneficiaries of this EULA.
12. Changes to This EULA
We may update this EULA from time to time. We will notify you of material changes through the App or by email at least 30 days before the changes take effect. Your continued use of the App after changes constitutes acceptance of the updated EULA.
