Terms of Use
1. Agreement and provider
These terms govern your use of Dual Messenger and its product website, provided by HK MobiUnity Technology Limited. Review them before using the service. If you cannot accept these terms, do not use the service. Additional consent may be requested for particular features, including AI uploads; accepting these terms alone does not substitute for that consent. Questions may be sent to support@mobiunityhk.com.
2. License and functionality
Subject to these terms, you receive a limited, personal, non-exclusive, non-transferable permission to use the app on devices you control, consistently with applicable App Store usage rules. The app lets you import chat exports, organize and browse backups and attachments, explore statistics, use linked WhatsApp Web sessions, and choose online AI analysis. Available features depend on your app version, device, purchase entitlement, and third-party service availability. This is not a cloud-backup or deleted-message-recovery guarantee.
3. Your files and permissions
You retain rights in your own content. You authorize the processing needed for the features you choose: local reading and organization of imported files, and transmission and processing for AI when you separately agree. This permission does not transfer ownership of your messages. You are responsible for having permission to import or submit other participants’ information and attachments. Keep an independent copy of important files and protect any export you share.
4. Linked accounts and third-party services
Use only accounts that you own or are authorized to manage and follow WhatsApp’s official Linked Devices process. Do not access another person’s account, impersonate others, intercept communications, or bypass access controls. Closing an app view does not itself unlink an account. WhatsApp/Meta, Apple, Google/Firebase, and Kimi provide services subject to their applicable terms. Dual Messenger is independent and is not affiliated with or endorsed by WhatsApp or Meta. Third-party names and marks remain their owners’ property.
5. AI and statistical limitations
AI analysis can upload a complete chat file after your consent. AI output is generated and may be incorrect, biased, or incomplete; verify it against original records. It is not professional medical, legal, financial, or psychological advice and should not be used alone for consequential decisions about a person. Statistics depend on the export format, parsing results, time data, and included content. Do not treat an analysis as a complete or authoritative account of a person or relationship.
6. Acceptable use
Do not use the service unlawfully, infringe others’ rights, submit content without necessary permission, exploit minors, distribute malicious content, interfere with service security, evade purchase restrictions, or overload the service. Do not reverse engineer except where applicable law gives you a right that cannot be excluded. You are responsible for your device security and the content you choose to share.
7. Purchases and privacy
Paid features and auto-renewing subscriptions may be offered through Apple. Review the product, entitlement, billing period, price, and any trial or offer shown before confirming a purchase. Manage billing through your Apple Account; deleting the app does not cancel a subscription. Information processing is described in our Privacy Policy. Purchasing access does not authorize submission of information you have no right to share.
8. Intellectual property
Except for your content and third-party materials, the app’s code, design, branding, and related materials belong to us or our licensors. These terms grant use of the service, not ownership of those materials. No permission is granted to use third-party trademarks beyond what the relevant owner or law permits.
9. Changes, interruptions, and termination
Features may change or be interrupted for maintenance, compatibility, security, or changes to third-party services. We may restrict use that violates these terms or creates a material security or legal risk, subject to applicable law and any required notice or remedy. You may stop using the app at any time. Stopping use does not cancel Apple billing or automatically remove copies held elsewhere. Paid-service changes remain subject to purchase commitments and mandatory consumer rights.
10. Responsibility and consumer rights
We do not promise uninterrupted service, perfect analysis, successful import of every export, or recovery of lost data. To the extent permitted by applicable law, we are not responsible for losses caused solely by unauthorized account use, third-party outages, or your failure to retain independent copies. Nothing in these terms excludes liability that cannot legally be excluded, or limits mandatory warranties, refunds, remedies, or other consumer rights. No exclusive court or governing-law restriction is imposed by this text; applicable mandatory law and competent dispute-resolution bodies remain available.
11. Apple-specific terms
These terms are between you and HK MobiUnity Technology Limited, not Apple. We, rather than Apple, are responsible for the app and its content, maintenance and support, and relevant product or intellectual-property claims as required by law. Apple has no obligation to provide maintenance or support. If the app fails to conform to an applicable warranty, you may notify Apple, which may refund its purchase price where applicable; other responsibilities remain with us to the extent required by law. You must comply with applicable third-party terms and export restrictions, and must not use the app where legally prohibited. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce the applicable provisions.
12. Updates and contact
We may revise these terms and give notice where required. The displayed revision date identifies this text version. For service questions or a concern that cannot be resolved through the app, contact support@mobiunityhk.com. Nothing here requires you to waive a legal right in order to seek assistance.
