Effective date: August 15, 2026 版本 / Version: 3.0 (English) · 3.0 (中文)

Terms of Service

These Terms of Service ("Terms") constitute a legally binding agreement between you and Qinhuangdao Doudou Technology Co., Ltd ("Doodlejay", "兜兜科技", "we", "us", or "our") governing your access to and use of the doodlejay.com website, our mobile applications published on the Google Play Store and Apple App Store, our online services, and any related products, content, features, or technologies operated by us (collectively, the "Services").

By accessing or using the Services you agree to be bound by these Terms. If you do not agree, you must not access or use the Services.

1. Acceptance of terms

You accept these Terms when you first access or use the Services, when you click "I agree", or when you sign a written or electronic ordering document that references these Terms. If you are accepting on behalf of an entity, you represent that you have the authority to bind that entity, in which case "you" refers to that entity.

If you do not agree to these Terms, you may not access or use the Services. The Services are not available to users who have been removed or suspended by Doodlejay.

2. Eligibility & account registration

2.1 Eligibility

You must be at least 18 years old (or the age of majority in your jurisdiction) to enter into a binding contract with us. If you are using the Services on behalf of an organization, you represent and warrant that you have authority to bind that organization to these Terms.

2.2 Account registration

To access certain features you may need to create an account. You agree to:

  • Provide accurate, current, and complete information during registration.
  • Maintain and promptly update your account information.
  • Maintain the security of your account credentials.
  • Promptly notify Doodlejay at security@doodlejay.com if you discover any unauthorized use of your account.
  • Accept responsibility for all activities that occur under your account.

Doodlejay is not liable for any loss or damage arising from unauthorized account access that you fail to report in a timely manner.

2.3 Identity verification

For certain Services (including VIP engagements and high-value contracts) we may require identity verification. You authorize us to make any inquiries we consider necessary to verify your identity.

3. Use of the Services

3.1 License

Subject to your compliance with these Terms, Doodlejay grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your personal or internal business purposes, as applicable.

3.2 Service availability

We aim for high availability but do not guarantee uninterrupted, secure, or error-free operation. We may perform planned maintenance, emergency maintenance, and capacity upgrades, and may need to suspend the Services to do so.

3.3 Service changes

We may add, modify, or discontinue features of the Services at any time, with or without notice. For paid Services we will provide reasonable advance notice of material changes that adversely affect you.

4. Mobile applications & app store terms

4.1 App stores

Our mobile applications are made available through the Google Play Store (operated by Google LLC) and the Apple App Store (operated by Apple Inc.). Your use of those stores is governed by:

4.2 Acknowledgements

You acknowledge and agree that:

  • These Terms are between you and Doodlejay only — not with Google or Apple.
  • Doodlejay, not Google or Apple, is solely responsible for the Apps and the content thereof.
  • Google and Apple have no obligation to provide maintenance or support for the Apps.
  • In the event of a failure of any App to conform to an applicable warranty, you may notify Google or Apple, and they may refund the purchase price (if any). To the maximum extent permitted by law, Google and Apple have no other warranty obligation with respect to the Apps.
  • Google and Apple are not responsible for addressing any claims by you or any third party relating to the Apps or your possession or use of the Apps, including but not limited to product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection or similar legislation.
  • In the event of a third-party claim that an App or your possession or use of an App infringes that third party's intellectual property rights, Doodlejay — not Google or Apple — is solely responsible for the investigation, defense, settlement, and discharge of any such claim.
  • You must comply with applicable third-party terms when using the Apps (e.g., your mobile data plan agreement).
  • Google and Apple, and their subsidiaries, are third-party beneficiaries of these Terms solely in respect of your use of the Apps, and upon your acceptance of these Terms, Google or Apple (as applicable) will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

4.3 In-app purchases

Apps may offer in-app purchases, subscriptions, or virtual items. All such transactions are processed by the relevant app store, and refunds are subject to the store's refund policy. You agree not to circumvent the store's payment mechanisms.

5. Subscriptions, payments & refunds

5.1 Fees

Certain Services are provided for a fee. Fees, billing cycles, and payment terms are specified in the applicable ordering document, in-app purchase flow, or pricing page. All fees are stated exclusive of taxes, which you are responsible for paying.

5.2 Billing

For recurring subscriptions:

  • You authorize us (or our payment processor) to charge your chosen payment method on a recurring basis.
  • Subscriptions auto-renew at the then-current price unless you cancel at least 24 hours before the end of the current billing cycle.
  • You can cancel at any time through your account settings or the relevant app store.

5.3 Late payment

Late payments may accrue interest at the rate of 1.5% per month (or the maximum rate permitted by law, whichever is lower) from the due date until paid. We may suspend Services for accounts that are more than 15 days overdue.

5.4 Refunds

Except where required by law (e.g., EU consumer right of withdrawal within 14 days for digital content not yet delivered, China's 7-day "no reason" rule for certain digital services), fees are non-refundable. For app store purchases, refunds are handled by the relevant app store under its own policy.

5.5 Price changes

We may change subscription prices with at least 30 days' notice. Continued use after the change takes effect constitutes acceptance. If you do not accept the change you may cancel before it takes effect.

5.6 Taxes

You are responsible for any sales, use, value-added (VAT, GST), withholding, or similar taxes, except for taxes on Doodlejay's net income.

6. Intellectual property rights

6.1 Doodlejay IP

The Services, including all source code, object code, designs, graphics, logos, trademarks, service marks, trade names, audio recordings, video, photographs, animations, text, and the selection, arrangement and "look and feel" thereof, are owned by Doodlejay, its licensors, or both, and are protected by copyright, trademark, patent, trade secret, and other intellectual property laws.

6.3 Reservation of rights

All rights not expressly granted to you in these Terms are reserved by Doodlejay and its licensors. No license is granted by implication, estoppel, or otherwise.

6.4 Feedback

Any feedback, suggestions, or ideas you provide about the Services may be used by Doodlejay without restriction or compensation to you.

6.5 Open source

The Services may include open source software components, which are licensed to you under their respective open source licenses. In the event of a conflict between these Terms and an open source license, the open source license controls with respect to that component.

Your use of third-party services is at your own risk and subject to the third party's terms and privacy policy.

10. Confidentiality

Either party may disclose Confidential Information to the other in connection with the Services. The receiving party agrees to protect the disclosing party's Confidential Information with the same degree of care it uses to protect its own confidential information (and in no event less than a reasonable degree of care), and not to use or disclose it except as necessary to perform under these Terms or as required by law. "Confidential Information" means non-public information that is identified as confidential or that, given its nature, a reasonable person would understand to be confidential.

11. Privacy & data protection

Our collection and use of personal information is described in our Privacy Policy, which is incorporated into these Terms by reference. By using the Services you consent to the data practices described in the Privacy Policy.

12. Warranties & disclaimers

12.1 Mutual warranties

Each party represents and warrants that it has the full power and authority to enter into these Terms.

12.2 Doodlejay warranties

Doodlejay warrants that the Services will perform materially in accordance with any documentation provided. Your sole and exclusive remedy, and Doodlejay's entire liability, for breach of this warranty is for Doodlejay to use commercially reasonable efforts to correct the non-conformity or, at Doodlejay's option, to refund the fees paid for the affected Services for the period of non-conformity.

12.3 Disclaimers

EXCEPT AS EXPRESSLY SET FORTH IN THESE TERMS, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. Doodlejay does not warrant that the Services will be uninterrupted, error-free, or free of harmful components, or that defects will be corrected.

Doodlejay does not warrant, endorse, guarantee, or assume responsibility for any product or service advertised or offered by a third party through the Services, and Doodlejay will not be a party to or in any way monitor any transaction between you and third-party providers of products or services.

No advice or information, whether oral or written, obtained by you from Doodlejay will create any warranty not expressly stated in these Terms.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL DOODLEJAY, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM (i) YOUR ACCESS TO OR USE OF (OR INABILITY TO ACCESS OR USE) THE SERVICES; (ii) ANY CONDUCT OR CONTENT OF ANY THIRD PARTY ON THE SERVICES; (iii) ANY CONTENT OBTAINED FROM THE SERVICES; OR (iv) UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR TRANSMISSIONS OR CONTENT, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, WHETHER OR NOT WE HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGE.

IN NO EVENT WILL DOODLEJAY'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES EXCEED THE GREATER OF (a) THE AMOUNT YOU HAVE PAID TO DOODLEJAY UNDER THESE TERMS IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE LIABILITY, OR (b) ONE HUNDRED U.S. DOLLARS (US$100).

The limitations in this section apply to the maximum extent permitted by law. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you.

14. Indemnification

You agree to defend, indemnify, and hold harmless Doodlejay and its affiliates, officers, directors, employees, agents, suppliers, and licensors from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to (a) your use of the Services; (b) your User Content; (c) your violation of these Terms; or (d) your violation of any applicable law or the rights of a third party.

15. Term & termination

15.1 Term

These Terms remain in effect for as long as you use the Services. For paid Services, the term is the period specified in your ordering document.

15.2 Termination by you

You may terminate these Terms at any time by stopping use of the Services and closing your account. For paid Services, you may terminate at the end of the current billing cycle.

15.3 Termination by Doodlejay

We may terminate or suspend your access to the Services at any time, with or without cause, with or without notice, including (without limitation) if we believe that you have violated these Terms.

15.4 Effect of termination

Upon termination:

  • Your right to use the Services immediately ceases.
  • We may delete your account data and User Content, subject to our retention policies and applicable law.
  • Provisions that by their nature should survive termination will survive, including ownership, disclaimers, indemnification, limitations of liability, and dispute resolution.
  • You remain liable for any fees owed up to and including the date of termination.

16. Suspension

In addition to termination rights, we may suspend the Services (in whole or in part) without liability if:

  • You breach these Terms or any ordering document.
  • We reasonably believe your account has been compromised.
  • We are required to do so by law, regulation, or a government or platform order.
  • There is an emergency, security incident, or force majeure event.
  • You fail to pay undisputed fees when due.

We will use commercially reasonable efforts to give you advance notice of suspension where practicable.

17. Modifications to the Services & terms

17.1 Modifications to the Services

We may modify the Services at any time. For material adverse changes to paid Services, we will provide reasonable advance notice (typically 30 days for active subscriptions).

17.2 Modifications to these Terms

We may update these Terms from time to time. The "Effective date" at the top indicates the latest revision. For material changes we will provide additional notice (e.g., in-app banner, email, or push notification) where required by law. Your continued use of the Services after the effective date constitutes acceptance of the updated Terms. If you do not accept the updated Terms you may stop using the Services and (for paid Services) terminate your subscription.

18. Dispute resolution & governing law

18.1 Informal resolution

Before filing a formal claim, you agree to first contact us at legal@doodlejay.com and attempt to resolve the dispute informally. We will attempt to resolve the dispute by contacting you via email. If a dispute is not resolved within 30 days of submission, you or Doodlejay may pursue formal resolution.

18.2 Arbitration (where permitted)

For users in jurisdictions where binding arbitration is enforceable (and to the maximum extent permitted by law), any dispute arising out of or relating to these Terms or the Services will be finally settled by binding arbitration administered by the China International Economic and Trade Arbitration Commission (CIETAC) under its then-current arbitration rules, in Beijing, in English and Chinese, before a single arbitrator. Notwithstanding the foregoing, either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent or stop infringement of intellectual property rights.

18.3 Class action waiver

Where permitted by law, you and Doodlejay agree that any proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If this waiver is found unenforceable, the arbitration provision will be void.

18.4 Exceptions

Nothing in this section prevents either party from seeking injunctive relief to protect its intellectual property or confidential information in any court of competent jurisdiction.

18.5 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 People's Republic of China, without regard to its conflict-of-law principles. The United Nations Convention on Contracts for the International Sale of Goods (CISG) does not apply.

18.6 Consumer rights

Nothing in these Terms is intended to exclude, limit, or otherwise affect your rights as a consumer under the mandatory laws of your country of residence (e.g., the EU consumer protection directives, the UK Consumer Rights Act 2015, the U.S. Magnuson-Moss Warranty Act, or China's Consumer Rights Protection Law).

19. Notices

Notices to you may be sent to the email address associated with your account, or via in-app notifications. Notices to Doodlejay must be sent to legal@doodlejay.com with a copy to vip@doodlejay.com. Legal notices are deemed given (a) when delivered by email with confirmation of transmission, (b) three business days after deposit in the mail, or (c) the next business day after dispatch by recognized overnight courier.

20. Miscellaneous

20.1 Entire agreement

These Terms, together with the Privacy Policy and any ordering documents, constitute the entire agreement between you and Doodlejay regarding the Services and supersede all prior agreements, communications, and proposals (oral or written) on the same subject matter.

20.2 Severability

If any provision of these Terms is held to be invalid or unenforceable, that provision will be enforced to the maximum extent permitted by law, and the remaining provisions will remain in full force and effect.

20.3 No waiver

Our failure to enforce any right or provision of these Terms will not be considered a waiver of such right or provision.

20.4 Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms without your consent to (a) an affiliate or (b) a successor in connection with a merger, acquisition, or sale of all or substantially all of our assets.

20.5 No agency

These Terms do not create any agency, partnership, joint venture, or employment relationship between you and Doodlejay.

20.6 Force majeure

Neither party will be liable for any delay or failure to perform (other than payment obligations) due to causes beyond its reasonable control, including acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, pandemics, network or power failures, strikes, or shortages of transportation, facilities, fuel, energy, labor, or materials.

20.7 Language

The English version of these Terms is the controlling version. Translations (including the Chinese version) are provided for convenience only.
