By accessing, downloading, installing, registering for, or otherwise using the Services, you confirm that you have read, understood, and agree to be bound by these Terms, our Privacy Policy, and any additional terms posted within the Services. If you do not agree, you must not use the Services.
If you are agreeing to these Terms on behalf of a company, organization, government, or other legal entity, you represent and warrant that you have the authority to bind that entity, in which case "you" refers to that entity. If you do not have such authority, you must not accept these Terms or use the Services on behalf of any such entity.
2. Description of the Services

- Software updates, support, and documentation.

3. Accounts & Registration

- You must provide accurate, current, and complete information.

If you are under the applicable minimum age, you may not use the Services unless your parent or legal guardian has reviewed and agreed to these Terms on your behalf.
4.2 Children's Apps
Where we publish applications in the Apple "Kids" category or rated 4+ on the App Store, additional COPPA-compliant safeguards apply. Our practice in such apps is described in our Children's Privacy section.
4.3 Jurisdictional Restrictions
You represent and warrant that you are not located in, under the control of, or a resident of any country or territory that is the target of comprehensive U.S. sanctions (e.g., Cuba, Iran, North Korea, Syria, the Crimea, Donetsk, and Luhansk regions of Ukraine) or that is otherwise restricted by applicable U.S. or international law from accessing the Services. Further, you are not a person identified on the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) list of Specially Designated Nationals (SDN) or any equivalent list maintained by the European Union, the United Kingdom, the United Nations, or other applicable authority.
5. License & Permitted Use

6. Intellectual Property Rights
6.1 Our IP
All rights, title, and interest in and to the Services, including all patents, copyrights, trademarks, trade secrets, design rights, database rights, and any other intellectual property rights, are and shall remain the exclusive property of dingfengtrad.com and its licensors. The Services are protected by copyright and other intellectual-property laws and by international treaties.
6.2 Trademarks
"dingfengtrad," the dingfengtrad logo and mark, and the names of our Apps are trademarks of dingfengtrad.com. Apple, iPhone, iPad, Mac, iOS, iPadOS, macOS, watchOS, visionOS, App Store, and Mac App Store are trademarks of Apple Inc., registered in the United States and other countries. Google Play, Android, and other related marks are trademarks of Google LLC. All other trademarks referenced are the property of their respective owners.
6.3 Feedback
If you submit suggestions, ideas, or feedback about the Services, you grant us a worldwide, non-exclusive, royalty-free, perpetual, irrevocable, and fully sublicensable right to use, modify, and incorporate such feedback into our products and services without restriction or obligation to you.
7. User Content & Local Files
Most of the data you generate in our Apps (encrypted document vaults, creative-capture notes, automation rules, fitness logs) is stored only on your device and never sent to our servers. You retain all ownership rights to such data.
Where you voluntarily submit content to us (for example, support emails, screenshots, bug reports), you grant us a non-exclusive, worldwide, royalty-free, limited license to use that content for the purposes of responding to your request, improving the Services, and preventing abuse. We will not use such content to train machine-learning models, advertise, or sell.
You confirm that you own or have the rights to any content you submit, and that submission does not violate any third-party rights.
8. Purchases, Pricing & Refunds
8.1 Paid Applications & One-Time Purchases
Where an App is offered for a one-time purchase, the displayed price is the price you pay. Payment processing is handled exclusively by Apple's App Store (or the equivalent distribution platform), and you agree to the applicable App Store payment terms.
8.2 Refund Policy
Because payment for App Store apps is processed by Apple (or the relevant platform), refund requests must be directed to Apple through https://support.apple.com/ ("Report a Problem" → "Apps" → select app → "Problem" → "Request a refund"). We do not have visibility into or control over these transactions, and we cannot unilaterally issue refunds. In exceptional circumstances where Apple directs you to us, we will endeavor to resolve the matter within 14 business days.
9. Subscriptions & Auto-Renewal
Where an App includes a subscription component, the following applies:
- The price, term, and auto-renewal behavior are disclosed in the App Store subscription screen before purchase.
- Subscriptions auto-renew at the end of each period unless you turn off auto-renewal at least 24 hours before the end of the current period (Apple's minimum).
- You may manage or cancel subscriptions via your Apple ID settings at any time.
- Free trial terms, where offered, are described in the App Store listing. If a free trial converts to a paid subscription, you will be charged the indicated price unless you cancel before the trial ends.
- Where required by local law (e.g., in California under Cal. Bus. & Prof. Code §17602, in the UK under Consumer Contracts Regulations, etc.), we provide additional disclosures appropriate to the jurisdiction.
10. In-App Purchases & Virtual Items
Some Apps may offer in-app purchases (IAPs), consumable virtual currency, non-consumable unlocks, or other virtual items. All such transactions are processed by the platform (Apple's IAP system) and are subject to:
- Apple's Terms of Service and Payment Terms.
- The pricing displayed in the App Store at the time of purchase.
- Restoration rules — non-consumable IAPs are associated with your Apple ID and can be restored by signing in. Consumable IAPs (e.g., tokens, credits) are not restorable.
- Our right to issue refunds or credits for documented technical issues, at our discretion.
Virtual items have no monetary value outside the App and are not redeemable for cash.
11. Advertising, Ad SDKs & Tracking Disclosure
Where an App displays advertising, the additional terms in this Section 11 apply. Our detailed disclosures about ad networks, ad mediation, ATT, and country-specific policies are in our Privacy Policy (in particular Sections 8, 9, 10, 11, and 17). The summaries below form part of these Terms.
11.1 Ad-Supported vs. Premium Apps
Most Apps we publish are premium — purchased once with no advertising. Where an App is ad-supported, the App Store listing will identify the App as "Free" with optional in-app upgrades to remove ads, or as "Free" with advertising. The privacy label for each App accurately reflects the advertising model.
11.2 Ad Networks Used
Where an App displays ads, the ad networks disclosed in Privacy Policy §9 may be present, including without limitation: Google AdMob, Google Ad Manager, Google AdSense, Meta Audience Network, Unity Ads, AppLovin, ironSource, Vungle, Chartboost, InMobi, Pangle (ByteDance), Mintegral, Tapjoy, Start.io, Digital Turbine (Fyber), Smaato, Verizon Media, MoPub (legacy), Ogury, BidMachine, Amazon Publisher Services, Criteo (consent-gated), Sharethrough, Taboola, Outbrain, TripleLift, OpenX, PubMatic, Index Exchange, Magnite, AdColony, Liftoff, and HyprMX. The exact list enabled in any given App is documented in that App's PrivacyInfo.xcprivacy manifest and its App Store privacy label.
11.3 Ad Mediation & Bidding
Where mediation is used, we engage one or more mediation platforms — most commonly AppLovin MAX, Google AdMob Mediation, or ironSource LevelPlay — to coordinate in-app bidding between the networks disclosed above. The list of in-app bidders that may participate is set out in our Privacy Policy §10.
11.4 Ad Formats
The ad formats our Apps may display are described in detail (including implementation safeguards) in our Privacy Policy §11, and include without limitation: open-screen / splash ads, rewarded video ads, interstitial ads, banner ads, native ads, native video ads, MREC ads, sticky / anchor ads, playable ads, and offerwall ads.
11.5 ATT Compliance
For Apple-platform apps, any code that constitutes "tracking" under Apple's App Tracking Transparency policy is gated behind the ATT prompt. Detailed compliance practices are described in our Privacy Policy §8.
11.6 User Controls
Users in jurisdictions requiring consent (EEA, UK, Switzerland, Brazil, etc.) interact with a CMP-compliant consent layer before any personalized advertising. Users may withdraw consent at any time via the in-app "Privacy Choices" link. Where applicable, the App offers an in-app purchase that disables all ad SDKs and removes advertising.
12. App Store & Distribution Platform Terms
Where we distribute Apps through the Apple App Store, Mac App Store, or other platform, additional terms imposed by that platform apply — including without limitation:
12.1 Apple App Store / Mac App Store
The license to use an Apple-platform App is limited to the rights granted under the Apple Media Services Terms and Conditions (and your usage is governed by Apple Inc.'s standard End User License Agreement, the App Store's Usage Rules set forth in the Apple Media Services Terms, and any additional terms required for Apple Vision Pro / visionOS). Maintenance and support for Apps distributed through the App Store are provided solely by us as required by applicable law. Apple is not responsible for maintenance or support.
12.2 Apple "Standard EULA" Reference
Where an Apple App is licensed under Apple's Standard End User License Agreement (EULA), the terms of that EULA apply. The Apple Standard EULA is available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. Where the Standard EULA is not used, a custom EULA may accompany the App; the platform-provided terms at the App Store listing always take precedence.
12.3 Google Play (Future Distribution)
Should we distribute Apps via Google Play, the Google Play Terms of Service and the Google Play Distribution Agreement apply. Apps distributed through Google Play must also comply with the Play Store's User Data policies and Families Policy where applicable.
12.4 Apple Privacy Manifest (PrivacyInfo.xcprivacy)
Each Apple-platform App we publish is accompanied by a Privacy Manifest declaring all data practices, used APIs, and tracking disclosures. The Manifest is version-controlled and updated with every release. App Store privacy labels are derived from these Manifests and accurately reflect actual practices.
13. Prohibited Use & Acceptable Conduct
You agree not to use the Services for any unlawful purpose or in any manner that violates these Terms. Without limitation, you must not:
- Use the Services to harass, defame, abuse, threaten, or otherwise violate the legal rights of any other person.
- Upload or transmit viruses, malware, ransomware, spyware, or any other malicious code.
- Probe, scan, or test the vulnerability of the Services or any system connected to them.
- Reverse engineer, decompile, or attempt to derive the source code of any software that implements the Services.
- Bypass or attempt to bypass authentication or security measures, or to use the Services in a manner designed to circumvent them.
- Use any robot, spider, scraper, or other automated means to access the Services for any purpose without our prior written consent.
- Interfere with or disrupt the integrity or performance of the Services.
- Use the Services for any commercial benchmarking, competitive analysis, or training of generative AI models.
- Use the Services in any manner that would expose us, our licensors, or our affiliates to liability.
We reserve the right to investigate and take appropriate legal action against anyone who, in our sole discretion, violates this Section, including reporting such conduct to law-enforcement authorities.
14. Security
We implement reasonable technical and organizational safeguards to protect the Services. However, no security system is impenetrable. You acknowledge that you are responsible for:
- Maintaining the security of your devices and accounts.
- Choosing strong, unique passwords and protecting your Apple ID or platform credentials.
- Keeping your operating system and the Apps updated to the latest available versions.
- Immediately notifying us of any suspected unauthorized use at contact@dingfengtrad.com.
Where you enable biometric gating (Face ID, Touch ID) or device passcode on your hardware, you significantly improve the protection of any locally stored data.
15. Privacy & Data Protection
Our privacy practices are described in detail in our Privacy Policy, which is incorporated into these Terms by reference. By accepting these Terms, you confirm that you have read and understood the Privacy Policy. Where there is a conflict between these Terms and the Privacy Policy, the Privacy Policy controls with respect to personal information.
16. Beta, TestFlight & Pre-Release Programs
From time to time we may make pre-release or beta versions of our Apps available through Apple's TestFlight or similar programs. By participating in a beta, you agree that:
- Beta builds may contain bugs and may cause data loss or other damage to your device. You back up your device before installing any beta build.
- Beta builds are provided "as is" without any warranty or guarantee.
- We may collect diagnostic, crash, and usage data from beta builds, as described in the Privacy Policy.
- We may discontinue a beta at any time, with or without notice.
- Any feedback you provide is governed by Section 6.3 above.
- You will not disclose confidential pre-release information outside of the beta program.
17. Third-Party Services & Open Source
Our Apps may rely on or be distributed alongside third-party services (such as Apple's iCloud, Apple's AuthenticationServices, Apple's WeatherKit, MapKit, AVFoundation, or similar platform APIs) and on open-source software components. Such services are governed by their own terms and privacy notices, which we do not control and for which we disclaim responsibility to the extent permitted by law.
Acknowledgements of open-source components used in our Apps are included in the in-app About / Legal screen, as required by the licenses of those components.
18. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE AND OUR AFFILIATES, LICENSORS, AND SERVICE PROVIDERS DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND TITLE.
WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE FROM HARMFUL COMPONENTS, OR THAT ANY DEFECTS WILL BE CORRECTED. NO ADVICE OR INFORMATION OBTAINED BY YOU FROM US OR THROUGH THE SERVICES WILL CREATE ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
19. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE OR OUR AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AGENTS, LICENSORS, SERVICE PROVIDERS, SUBCONTRACTORS, OR SUPPLIERS BE LIABLE FOR:
- ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES;
- ANY LOSS OF PROFITS, REVENUE, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES;
- ANY DAMAGES RESULTING FROM (A) YOUR ACCESS TO OR USE OF (OR INABILITY TO ACCESS OR USE) THE SERVICES; (B) ANY CONDUCT OR CONTENT OF ANY THIRD PARTY; (C) ANY CONTENT OBTAINED FROM THE SERVICES; OR (D) UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR TRANSMISSIONS OR CONTENT;
WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, STATUTE, OR ANY OTHER LEGAL THEORY, WHETHER OR NOT WE HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGE.
IN ANY CASE, OUR AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO US FOR USE OF THE SERVICES DURING THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE LIABILITY, OR (B) ONE HUNDRED U.S. DOLLARS (USD $100).
NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW (INCLUDING DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, FRAUD, OR FRAUDULENT MISREPRESENTATION).
20. Indemnification
You agree to defend, indemnify, and hold harmless dingfengtrad.com and our affiliates, officers, directors, employees, contractors, agents, licensors, service providers, subcontractors, and suppliers from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to your violation of these Terms or your use of the Services.
21. Termination
21.1 By You
You may stop using the Services at any time. To terminate an account, contact us at contact@dingfengtrad.com. Uninstalling the Apps does not by itself terminate a subscription or other entitlement; for subscriptions, manage via your Apple ID settings.
21.2 By Us
We may suspend or terminate your access to all or part of the Services at any time, with or without notice, if we reasonably believe:
- You have violated these Terms.
- You have engaged in fraudulent or illegal activity.
- Continuation poses a security or legal risk.
- We are required to do so by law or by an app-store platform.
Termination does not relieve you of any obligation to pay fees accrued before termination.
21.3 Effect of Termination
Upon termination, your license to use the Apps ends. Sections that, by their nature, should survive termination — including those addressing intellectual property, disclaimers, indemnity, limitations of liability, and dispute resolution — will survive.
22. Modifications to These Terms
We may modify these Terms from time to time. When we do, we will update the "Last Updated" date at the top of this page. If changes are material, we will provide additional notice — for example by email (where we have your contact details), by an in-app banner, or by a notice on our homepage — at least 30 days before the changes take effect, where required by applicable law.
Your continued use of the Services after a change constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Services and may terminate your account.
23. Governing Law
These Terms and any non-contractual obligations arising out of or in connection with them are governed by and construed in accordance with the laws of the Commonwealth of Virginia, United States of America, without giving effect to any conflict-of-laws principles that would require the application of the law of any other jurisdiction.
For consumers in jurisdictions that grant mandatory protections under their local consumer law (including the EU, the UK, Australia, Canada, New Zealand, Brazil, China, Japan, South Korea, Singapore, etc.), nothing in these Terms affects your right to rely on those mandatory protections.
24. Dispute Resolution
24.1 Informal Resolution
Before filing any formal action, you agree to first contact us at contact@dingfengtrad.com and attempt to resolve the dispute informally. We will attempt to resolve the dispute informally by contacting you via email. If a dispute is not resolved within 30 days of submission, you or we may pursue formal resolution.
24.2 Court of Competent Jurisdiction
Subject to applicable law and Section 24.3, you and we agree that any judicial action will be brought exclusively in the state or federal courts located in the Commonwealth of Virginia, City of Richmond (or the nearest available jurisdiction), and you hereby consent to the personal jurisdiction and venue of those courts.
24.3 Consumer Rights & Mandatory Arbitration Overrides
Nothing in this Section overrides the rights of a consumer under the laws of their jurisdiction. EU and UK consumers may bring claims in their local courts; Australian consumers may bring claims in their local courts; California consumers retain their right to bring claims under the CCPA and CLRA; Quebec consumers may elect the forum of their residence; and so on. Where local law requires disputes to be resolved in a specific forum, that forum is exclusive.
24.4 Apple App Store Specific
Where permitted by the Apple App Store terms or other applicable platform rules, you may also have the right to bring a claim against us through the small-claims tribunal or analogous body in your jurisdiction.
25. Export Controls & Sanctions
The Apps and Services are subject to U.S. and international export control laws and regulations, including the U.S. Export Administration Regulations (EAR), the International Traffic in Arms Regulations (ITAR), and the sanctions programs administered by OFAC, the EU, the UK, and the UN. You agree to comply with all such laws and regulations and represent that you are not located in, under the control of, a resident of, or a national of any country subject to comprehensive sanctions, and that you are not on any sanctions or denied-persons list.
26. Miscellaneous
26.1 Entire Agreement
These Terms, together with the Privacy Policy and any additional terms referenced in a specific App or service, constitute the entire agreement between you and us regarding the Services, and supersede all prior or contemporaneous communications and proposals, whether oral or written.
26.2 Severability
If any provision of these Terms is held to be invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if not possible, severed, and the remaining provisions will remain in full force and effect.
26.3 No Waiver
Our failure to enforce any right or provision of these Terms will not be deemed a waiver of such right or provision. Any waiver must be in writing and signed by us.
26.4 Assignment
You may not assign or transfer any of your rights or obligations under these Terms without our prior written consent. We may assign these Terms, in whole or in part, to any affiliate, successor entity, or purchaser of substantially all of our assets.
26.5 Force Majeure
We will not be liable for any delay or failure to perform resulting from causes outside our reasonable control, including acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, pandemics, network or telecommunications failures, shortages of transportation, fuel, energy, labor, or materials, or platform (e.g., App Store) outages.
26.6 No Third-Party Beneficiaries
Except as expressly stated (e.g., Apple's third-party beneficiary rights under the Apple Standard EULA), these Terms do not confer any rights or remedies upon any person other than you and us.
26.7 Headings
Section headings are for convenience only and do not affect interpretation.
27. How to Contact Us
For any question, complaint, or notice relating to these Terms:
We will respond to all verifiable written notices within the timeframes required by applicable law or these Terms, whichever is shorter.
