StudyEn · Terms of Service

1. Acceptance & Changes

Before downloading, installing, or using StudyEn (the "App"), please read this agreement carefully. By using the App you accept it in full; if you disagree, please stop using it. The agreement may change as the App evolves — material changes will be announced on this page with a new effective date, and continued use means you accept the updated agreement.

2. Service & License

StudyEn is a software product developed and maintained by an independent developer.System requirements: iOS 26.0 or later.

Subject to your compliance with this agreement, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control. We keep improving the App; features may change between versions, and important changes are noted in the changelog.

3. Accounts

StudyEn requires no account. If you use system-provided services such as cloud sync, that provider's terms also apply to the data involved.

4. Acceptable Use

You agree to use the App lawfully, to ensure that content you enter or import is lawful, and not to use the App for any illegal or infringing activity. You will not reverse engineer or decompile the App, copy or modify it or create derivative works, rent, resell, or redistribute it without authorisation, or bypass its technical limits, membership restrictions, or purchase mechanisms.

5. Intellectual Property

Except for content you create or lawfully own, the App — including its code, interface, icons, copy, and design — is owned by the developer. You may not copy, modify, reverse engineer, sell, or redistribute it without authorisation. Content you create or import remains yours or your licensors'; we claim no ownership over your data.

6. Disclaimer of Warranties

The App is provided "as is". We keep improving it, but to the extent permitted by law we make no promises that it will meet your particular needs, run uninterrupted, timely, securely, or error-free, or that the data it presents is fully accurate or reliable. You are responsible for regularly backing up data you create with the App; we are not liable for losses caused by failure to back up.

7. Limitation of Liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, punitive, or consequential damages (including data loss, business interruption, or lost profits) arising from use of or inability to use the App, even if advised of the possibility. Our total liability for the App or this agreement is capped at what you actually paid for the App in the past 12 months (zero if you paid nothing).

8. Changes & Termination

You can stop using the App anytime by deleting it; local data on your device remains yours and can be exported with the app's export features. If an app must be discontinued, we will announce it in the app or on this page ahead of time and provide a data-export path where possible. If you breach this agreement, we may limit or suspend your use of the relevant services or features.

9. Governing Law & Disputes

This agreement is governed by the laws of the People's Republic of China. Disputes shall first be resolved amicably; failing that, either party may bring suit before a court of competent jurisdiction.

Effective date: 2026-09-26 · The App is also subject to Apple's standard EULA.

Copyright of imported materials

Built-in learning content — word lists, chunks, pronunciation drills, and the phonetics chart — is provided for your personal study only. Copyright in the course audio and subtitle files you import via the Files app remains with the original rights holders; please make sure you hold a valid licence to use them (such as proof of purchase or the platform’s terms). Any dispute arising from importing or using copyrighted material is the responsibility of the person who imported it.

Learning outcomes and data safety

StudyEn provides methods, plans, and practice tools for learning. It makes no promise of any test score, speaking ability, or other learning outcome — results depend on your own effort and practice.

Your learning data is stored on your device; when iCloud Backup is enabled in system settings, your learning state and spoken-diary recordings are backed up automatically by iOS to your own iCloud account (course audio and pronunciation caches are excluded). The developer runs no servers, cannot keep a copy for you, and cannot restore data on your behalf; please make good use of iCloud Backup and the in-app manual backup as described in the Privacy Policy. The developer is objectively unable to recover data lost through failure to enable backups, accidental deletion, uninstalling the app, loss of the device, or a system failure.
