Welcome to the iOS/iPadOS application "DulaTrackPro AI X" (also referred to as "DulaTrackProAIX", hereinafter "the App"). By downloading, installing, or using the App, you acknowledge that you have read, understood, and agree to these Terms of Use. If you are a minor, please read these Terms with your parent or guardian and obtain their consent before using the App or making any in-app purchases.
You bear full legal responsibility for all content you import, process, or export through the App (including but not limited to videos, audio, and images). If your content infringes upon third-party rights (including but not limited to copyrights, likeness rights, or privacy rights), you are solely responsible for any legal consequences. The App developer is not liable. The App provides only a technical processing tool. It does not review user content and assumes no responsibility for the legality, authenticity, or accuracy of user content.
To protect your purchase rights and ensure the App functions properly, the App requires a standard iOS/iPadOS system environment. If an abnormal runtime environment is detected, certain features may be restricted. This is to prevent unauthorized use and protect the legitimate rights of paying users.
If you violate any provision of these Terms — including but not limited to cracking, tampering with, or reverse-engineering the App, or using it in an abnormal device environment — the developer reserves the right to immediately terminate your license without refund. Upon termination, you must immediately cease using the App and delete all copies.
The App offers the following purchase options:
Actual prices are as displayed in the App and on the App Store. Previously purchased subscriptions or lifetime licenses can be verified and restored via the in-app "Restore Purchase" option (no duplicate charges). All purchases, refunds, and billing are handled by Apple in accordance with its policies. The developer does not process refunds directly. For refund requests, please contact Apple through official channels.
To protect legitimate users, the App may employ technical measures to restrict abnormal use.
Notice: The App license is for the purchaser's personal use only and may not be transferred, resold, or shared. Shared or proxy-purchased accounts obtained through third-party channels may pose security risks (e.g., account theft, password leaks) and may result in feature restrictions for violating these Terms. For the best experience and data security, we recommend purchasing through the official App Store.
We are committed to continuously improving the App. Based on user feedback and technological developments, future versions may include enhanced video processing features or algorithm optimizations. Subscribers and lifetime license holders will receive feature updates during their active license period (excluding major new modules, which will be detailed in-app). Specific update content and timing are subject to the actual released version. We do not commit to the release date or form of any specific feature.
The developer reserves the right to modify, update, suspend, or terminate the App (or any part of its features) at any time without prior notice. The developer assumes no liability for any service interruptions or feature changes caused by system maintenance, upgrades, policy changes, third-party service changes, or other reasons. If the App is removed from the App Store for any reason, existing purchasers may continue using their downloaded version, but the developer does not guarantee future updates or technical support.
To the maximum extent permitted by applicable law, the App is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, express or implied. The developer shall not be liable for any direct, indirect, incidental, special, punitive, or consequential damages arising from the use or inability to use the App (including but not limited to data loss, loss of profits, business interruption, or loss of business opportunities), even if advised of the possibility of such damages.
In no event shall the developer's total liability to you (whether based on contract, tort, or any other legal theory) exceed the amount you actually paid for the App in the 12 months preceding the claim.
The App and its related content (including but not limited to algorithms, interface design, icons, trademarks, and documentation) are protected by law. All rights belong to the developer. You may not copy, distribute, or use them for commercial purposes without permission.
We take your privacy and data security very seriously. For details on information processing and permissions, please refer to the App's Privacy Policy.
The formation, validity, interpretation, performance, and dispute resolution of these Terms shall be governed by the laws of the People's Republic of China (excluding Hong Kong, Macau, and Taiwan). Any dispute arising from or related to these Terms or the App shall first be resolved through friendly negotiation. If negotiation fails, either party may file a lawsuit with a competent People's Court in Zunyi, Guizhou Province, China.
We may update these Terms from time to time. If significant changes are made, we will notify you through appropriate means. Your continued use of the App after the Terms are updated constitutes acceptance of the revised Terms.
If there is any discrepancy between these Terms and the actual behavior of the App, the in-app prompts and feature descriptions shall prevail. Contact email: see Privacy Policy.
