Introduction

Welcome to "Are U OK" (Chinese name "心连心"; the "App" or the "Service"). The App is developed and operated independently by 张世博 (the "Developer").

These Terms of Service (the "Terms") are an agreement between you and the Developer about your use of the Service. Please read and fully understand all of the Terms before registering for or using the Service, especially the terms in bold that exclude or limit liability and those on governing law and dispute resolution. If you do not agree with any part of the Terms, please do not register for or use the Service. By tapping to agree, completing registration or actually using the Service, you are deemed to have read and agreed to be bound by the Terms.

If you are a minor under 18, please read the Terms with your guardian and use the Service only with your guardian's consent.

How the Developer processes your personal information is described in the Are U OK (心连心) Privacy Policy, which forms an integral part of the Terms.

1. The Service

  1. The App is a scheduled check-in tool for letting your family know you are safe: you check in on a schedule you choose; if you have not checked in by the deadline, the App first reminds you and, after the grace period ends, notifies the family members you added in advance whose link is active by in-app message, system push notification and/or email.
  2. The Service also offers features such as viewing each other's check-in records with family members, text/image/voice chat, check-in moods and photos, optional location sharing, fingerprint/face/face-liveness verification, and checking in from a home-screen widget/card. The features actually available depend on the App version you use, and the Developer may add, adjust or retire some features as appropriate.
  3. The Service is currently free. If paid features are introduced in the future, the Developer will clearly state the charges in advance, and you can choose whether to use them.

2. Important: the Service is not an emergency rescue service

Please make sure you understand and agree that:

  1. The App is only an auxiliary check-in reminder tool. It is not a medical, police, first-aid or other emergency rescue service, cannot replace emergency numbers such as 110, 120 and 119, and cannot replace the everyday care and attention of family and friends. In an emergency, please call the emergency number immediately or seek professional help.
  2. Whether reminders and alerts are delivered in time depends on many factors, such as your device's state (battery, network, system notification and background permissions, power-saving policies, etc.), mobile network and internet conditions, email providers, push providers, and whether your family members check them — many of which are beyond the Developer's control. The Developer will do its best to keep the Service stable but does not promise that alerts will always be delivered timely and accurately, nor that family members will receive or read them or take any action.
  3. Alerts are sent only to the family members you added whose link is active (adding an App user takes effect immediately; family added by email only must confirm first). You should make sure their contact details are accurate and valid, and set a reasonable check-in interval and grace period. The App will not send alerts when the check-in interval is too long, guarding is paused or turned off, or you have removed all family members.
  4. Location information comes from your device's location service, may be inaccurate or unavailable, and is for reference only.
  5. Check-ins must be truthful. Your family members rely on your check-in status to judge whether you are safe, and the App uses it to decide whether to send them overdue alerts. You should check in as safe only when you are actually safe; you must not check in as safe when you feel unwell, are in danger or need help, and you must not check in for someone else, operate the App on someone else's behalf, or create a false check-in status in any way. A false check-in may lead your family members to believe you are safe and not check on or help you in time, delaying rescue and causing serious consequences such as personal injury or property loss. The person who checks in bears all consequences and legal liability arising from a false check-in status, and the Developer is not liable. If you need help, call an emergency number such as 110 / 120 immediately, or use Emergency SOS to notify your family members.
  6. Before your first check-in, the App shows you the above in a pop-up, and you can check in only after you tick to agree; the App records the time you agreed.

3. Accounts

  1. You can register an account with an email address (or, once mobile-number features are available, a mobile number). You should provide true and valid registration information and complete verification with a verification code.
  2. You should keep your account and password safe and must not lend, transfer or sell your account to others. You bear the consequences, such as account theft, of failing to keep them safe; if you find your account has been stolen or is at risk, change your password immediately and contact the Developer.
  3. Your nickname and avatar must not contain illegal content, infringe others' rights or contain harmful information, and must not impersonate others.
  4. You can delete your account at any time as described in the Privacy Policy. After deletion, the account and related data are deleted and cannot be recovered.
  5. If your account violates the Terms, the Developer may, depending on the circumstances, issue a warning, restrict features, or suspend or terminate the Service.

4. Adding family members and other people's information

  1. You can add family members by OK ID, QR code, email or (once available) mobile number, or enter the email of someone who does not use the App as a family member. Before adding someone or entering their contact details, you should inform them and obtain their consent. Adding an App user takes effect immediately: they receive your check-in updates, overdue alerts and emergency help requests, and can choose to share back with you or remove themselves from your family list. Family added by email only receive alerts only after they confirm. To prevent abuse, the number of App users you can add as family per day is limited.
  2. Family members you added can see your check-in records (including mood, note and photo) and chat with you; once they add you too, you can see theirs. Please think carefully before sharing; you can remove a family member at any time to stop sharing.
  3. You must not use the Service to harass, stalk or monitor others, or to obtain other people's location or other personal information without their consent.

5. Rules of conduct

When using the Service you must comply with the laws and regulations of the People's Republic of China and must not use the Service to:

  1. publish, transmit or store information that opposes the basic principles of the Constitution, endangers national security, leaks state secrets, subverts state power, undermines national unity, damages national honour and interests, incites ethnic hatred or discrimination, undermines ethnic unity, promotes cults or superstition, spreads rumours, disturbs social order or stability, promotes obscenity, pornography, gambling, violence, murder or terror or instigates crime, insults or defames others, or infringes others' lawful rights and interests;
  2. send spam or advertising, or carry out fraud or other illegal activities;
  3. infringe others' intellectual property, portrait rights, privacy, personal information or other lawful rights and interests;
  4. register accounts maliciously, add strangers in bulk, or deliberately create false alerts;
  5. reverse engineer, decompile or crack the App, interfere with or damage the normal operation of servers and networks, exploit vulnerabilities, or access the Service in bulk by automated means;
  6. engage in other conduct that violates laws and regulations, public order and good morals, or the Terms.

If you violate the rules above, the Developer may lawfully delete the content concerned, restrict or terminate the Service to you and, where necessary, report to the competent authorities; you bear the resulting losses and legal liability.

6. User content

  1. The rights to the check-in moods, notes, photos, chat text, images, voice and other content you post in the Service ("User Content") belong to you or the original rights holder. You should make sure you have lawful rights to User Content and that it does not infringe any third party's lawful rights and interests.
  2. To provide the Service to you and your family members (such as storing, compressing, generating thumbnails, transmitting and displaying), you authorize the Developer to store, process and transmit User Content to the extent necessary to provide the Service. The Developer will not use your User Content for purposes other than the Service.
  3. The Developer does not review chats between users in advance, but may lawfully delete or block content upon complaint or when illegal content is found.

7. Intellectual property

The intellectual property in the App's software, interface design, icons, text and other related content belongs to the Developer or the relevant rights holders. Without the Developer's written permission, you must not copy, modify, distribute, sell or otherwise use such content, nor reverse engineer or decompile the App.

8. Changes, interruption and termination of the Service

  1. The Developer will do its best to keep the Service continuous and stable, but the Service may be interrupted or delayed by system maintenance, upgrades, server or network failures, problems with third-party services (such as cloud, CDN, email and push services), force majeure and other causes. The Developer will give notice in advance where possible and restore the Service as soon as possible.
  2. The Developer may decide to stop operating the Service for personal reasons. If so, the Developer will notify you at least 30 days in advance in the App or in another reasonable way, and delete or anonymize your personal information as required by law.

9. Disclaimers and limitation of liability

  1. To the maximum extent permitted by law, the Developer is not liable for reminders or alerts not being delivered in time, service interruptions or data loss caused by: problems with your device, network or system settings (including turning off notifications or background permissions, power-saving policies, etc.); inaccurate family member information you provided or family members not checking; third parties such as telecom operators, email providers, push providers, cloud or CDN providers; force majeure, hacker attacks, computer viruses and other causes beyond the Developer's control.
  2. The Service is provided free of charge. To the extent permitted by law, the Developer is not liable for indirect losses arising from the use of or inability to use the Service. This does not apply to personal injury or property loss caused by the Developer's intent or gross negligence, or to liability that cannot be excluded under laws and regulations.
  3. The Developer is not liable for any loss suffered by you, your family members or third parties because you provided a false check-in status (including checking in as safe when you are not, or checking in for someone else).
  4. If you cause losses to the Developer or third parties by violating the Terms or laws and regulations, you shall bear the corresponding liability according to law.

10. Changes to the Terms

The Developer may modify the Terms as laws and regulations change or the Service is adjusted. The modified Terms will be published in the App and on this page, and the "Last updated" date will be changed. For material changes, the Developer will notify you prominently, such as with a pop-up. If you do not agree with the modified Terms, you can stop using the Service and delete your account; if you continue to use the Service, you are deemed to agree to the modified Terms.

11. Governing law and dispute resolution

  1. The conclusion, performance, interpretation and dispute resolution of the Terms are governed by the laws of the People's Republic of China (for the purposes of the Terms, excluding the laws of the Hong Kong SAR, the Macao SAR and Taiwan).
  2. Any dispute arising from or relating to the Terms shall be resolved through friendly negotiation; if negotiation fails, either party may file a lawsuit with a people's court having jurisdiction.

12. Contact

If you have any questions, comments or complaints about the Terms, you can contact the Developer:

The Developer will reply within 15 working days after receiving your email.
