PhoneJail Terms of Service
Effective Date: 26 August 2026
Last Updated: 26 August 2026
If there is any inconsistency between the Chinese and English versions, the Chinese version will prevail, except where applicable law requires otherwise.
1. Acceptance and Scope
Welcome to PhoneJail (the “App”). These Terms of Service (the “Terms”) form an agreement between you and Shanghai Infinite Imagination Information Technology Co., Ltd (the “Company,” “we,” “us,” or “our”) governing your download, installation, and use of the App. By downloading, installing, launching, or using the App, you confirm that you have read, understood, and agree to be bound by these Terms. If you do not agree with any part of these Terms, stop using the App and uninstall it.
These Terms apply to all features and versions of the App. Our handling of personal information is described in the PhoneJail Privacy Policy, which forms an integral part of these Terms. If you obtain the App through the App Store, Google Play, or another distribution platform, you must also comply with that platform’s terms. Where these Terms conflict with a platform’s terms, the platform’s terms govern the relationship between you and that platform.
2. Description of the Service
2.1 Local Timing and Reminders
The App provides a focus timer and reminder service that runs locally on your device. After you set a focus duration and put the phone down, the App uses the device’s motion and orientation sensors to determine whether the phone has been lifted or moved, and issues a warning through vibration, sound, or an on-screen prompt when an interruption is detected. The App also provides supporting features such as focus records, statistics, and trend displays.
2.2 The App Cannot Lock Your Device
The App cannot lock your device and does not take over any function of the operating system. The App cannot prevent you from answering calls, viewing notifications, using other applications, or closing the App, and you may end a focus session at any time. On supported devices, if you expressly authorize the App to use the system’s app-restriction capabilities, those restrictions are enforced by the operating system; their scope, effect, and removal depend on the operating system rather than on any enforcement by the App. You may revoke that authorization in system settings at any time.
2.3 Data Storage and Accounts
The current version does not offer account registration or sign-in, does not perform cloud synchronization, and contains no advertising or behavioral-analytics components. Focus records and settings are stored only on your device. Clearing the App’s stored data, uninstalling the App, changing devices, or damage to your device may therefore result in permanent and irreversible loss of that data. You are responsible for deciding whether to keep separate copies of any information you need.
3. Safety Disclaimer
Do not use the App while driving, operating machinery, engaging in any other high-risk activity that requires your attention, or in any situation in which you must remain immediately reachable. The App’s reminder mechanism produces vibration and sound that may distract you, and placing your phone out of sight may delay your awareness of and response to an emergency.
During a focus session, you may end the session, pick up your phone, and use all of the device’s communication functions at any time, including placing emergency calls. The App does not block any incoming call, message, or system notification, and does not delay the operating system’s handling of emergencies.
You are solely responsible for ensuring that your use of the App does not cause you to miss urgent communications or delay urgent matters. If you may need to receive emergency contact, do not start a focus session, do not enable Library/Silent Mode or app restrictions, and configure the emergency bypass or Do Not Disturb exceptions provided by your operating system for your emergency contacts. To the maximum extent permitted by applicable law, we are not liable for missed calls, unread messages, delays, personal injury, property damage, or any other consequence arising from your use of, or inability to use, the App.
The App is not a medical device and does not provide medical, psychological, or health-care advice. If you have health concerns relating to attention, sleep, or mood, consult a qualified professional.
4. Your Responsibilities and Prohibited Conduct
You agree to comply with applicable laws when using the App and are responsible for the security of your device, your system settings, and your surroundings. You must not:
- reverse engineer, decompile, or disassemble the App, or otherwise attempt to derive its source code or extract its components, except to the extent expressly permitted by applicable law;
- modify, translate, or adapt the App, or create derivative works based on it;
- rent, lend, sell, sublicense, or distribute the App, or use it for any commercial purpose not authorized by us in writing;
- remove, obscure, or alter any proprietary notice, trademark, or logo within the App;
- interfere with the normal operation of the App through automated programs or scripts, falsify sensor data, or fabricate focus records;
- use the App for unlawful activities or in any manner that infringes the rights of us, other users, or any third party; or
- circumvent, disable, or interfere with the security mechanisms of the App or of the operating system on which it runs.
You must also ensure that you hold lawful rights to the device you use and, where a device is shared with others, obtain any consent necessary for your use of the App. To the extent permitted by law, you are responsible for the losses we incur as a result of your breach of these Terms or of applicable law.
5. Intellectual Property
The App and all of its components, including without limitation software code, interface design, graphics, icons, animations, sound effects, text, the name “PhoneJail,” and related marks, are owned by us or the respective rights holders and are protected by applicable copyright, trademark, and other intellectual-property laws.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable license to install and use the App for personal, non-commercial purposes on devices you own or control. All rights not expressly granted in these Terms are reserved. Local data generated through your use of the App, such as focus records, belongs to you.
6. Disclaimer of Warranties
The App is provided “as is” and “as available.” To the maximum extent permitted by applicable law, we make no warranties of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, or uninterrupted operation.
We do not warrant that the App is compatible with any particular device or operating-system version, that sensor detection, reminders, vibration, or sound will be timely, accurate, or effective in all circumstances, or that the App will be free of defects or interruptions. Sensor detection depends on device hardware, placement, system limitations, and background-execution policies, and may produce false negatives or false positives.
Some jurisdictions do not allow the exclusion of implied warranties, so the exclusions above may not apply to you in full. In that case, any such warranty is limited to the shortest period permitted by applicable law.
7. Limitation of Liability
To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, punitive, or consequential damages arising out of your use of, or inability to use, the App, including loss of profits, business interruption, loss of data, missed communications, or damage to goodwill, whether based on contract, tort, or any other legal theory, and whether or not we were advised in advance of the possibility of such damages.
To the maximum extent permitted by applicable law, we exclude our liability under these Terms and in connection with the App. Where liability nevertheless arises under applicable law, our total aggregate liability is limited to the total amount you have actually paid us for obtaining and using the App.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for intentional misconduct or gross negligence, liability for fraud, and liability for death or personal injury caused by our acts.
8. Changes, Suspension, and Termination
We may update, modify, suspend, or discontinue all or part of the App at any time in order to improve features, adapt to changes in operating systems, or meet security or legal requirements. Where a change or discontinuation is material, we will give advance notice by reasonable means, such as an in-App notice, store release notes, or another appropriate method.
If you breach these Terms or applicable law, we may terminate the license granted to you to the extent reasonably necessary. You may terminate these Terms at any time by ceasing to use the App and uninstalling it. Provisions that by their nature should survive termination continue to apply, including those on intellectual property, disclaimer of warranties, limitation of liability, and governing law and dispute resolution.
The App relies on sensor, notification, and app-restriction capabilities provided by the operating system. If the policies of an operating system or distribution platform change, the corresponding features may become limited or unavailable. To the extent permitted by applicable law, we are not liable for such changes, but we will explain the situation where practicable.
9. Children and Minors
The App is not directed to children under 14. If you are under 14, do not use the App without the consent and guidance of a parent or other guardian. If your jurisdiction sets a different age of majority or age of digital consent, the local requirement applies.
A guardian should supervise a minor’s use of the App and make appropriate arrangements regarding device permissions, focus-duration settings, and emergency contact methods. By using the App, or by allowing a minor to use it, a guardian accepts these Terms.
10. Governing Law and Dispute Resolution
These Terms, and any dispute arising out of or in connection with them, are governed by the laws of the People’s Republic of China (for the purposes of this clause, excluding the laws of the Hong Kong Special Administrative Region, the Macao Special Administrative Region, and the Taiwan region), without regard to its conflict-of-laws rules.
In the event of a dispute arising out of these Terms or the App, the parties will first attempt to resolve it amicably using the contact details below. If the dispute is not resolved, either party may bring proceedings before the people’s court at our domicile, namely the Shanghai Pudong New Area People’s Court.
If you are a consumer, these Terms do not affect the rights available to you under the mandatory consumer-protection laws of your place of residence, including the right to bring proceedings before a competent local court.
If any provision of these Terms is held invalid or unenforceable, that provision will be replaced or severed to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
11. Changes to These Terms
We may update these Terms to reflect changes in features, technology, or legal requirements. An updated version takes effect on the effective date stated in it. For material changes, we will notify you through an in-App notice, a prominent announcement, or another appropriate method, and obtain renewed consent where required by law.
The “Last Updated” date at the top indicates the latest revision. Continuing to use the App after an update takes effect constitutes acceptance of the updated Terms. If you do not accept them, stop using the App and uninstall it.
