Third-party intellectual property

The Services may display, include, or provide access to content, software, libraries, models, data, or other materials owned by third parties (“Third-Party Content”). Third-Party Content may be provided to you under separate terms and conditions specified by the relevant third party.

All intellectual property rights in Third-Party Content belong to their respective owners and may be protected by copyright, trademark, and other laws.

4. Privacy Policy

For information about how VieSpeak collects, uses, and shares your personal data, please see our Privacy Policy. By using the App, you acknowledge that your personal data will be collected and used in accordance with our Privacy Policy.

5. Fees and Payment

The App may offer certain features, content, or services for a fee, including monthly or annual subscription plans (“Paid Subscriptions”). If you choose to make a purchase in the App or on our Site (each, an “In-App Purchase”), you agree to pay the applicable fees.

In-App Purchases are processed by third-party payment providers, such as the Apple App Store and Google Play Store (each, a “Payment Provider”). Prices, billing frequency (for example, monthly or annual), auto-renewal terms, and any other purchase terms will be presented to you by the relevant Payment Provider at or before the time of purchase. Those terms are between you and the Payment Provider and are in addition to these Terms.

If your purchase is a Paid Subscription, it will typically renew automatically at the end of each subscription period at the then-current price, and will continue to renew in this way unless you cancel in accordance with the instructions provided by the relevant Payment Provider. You can manage or cancel your subscription in your account settings with the applicable Payment Provider. We may also provide information about your current subscription and instructions on how to cancel in the “Account Settings” section of the App for your convenience, but any billing changes or cancellations must be completed through the applicable Payment Provider.

VieSpeak may offer promotional codes (“Promo Codes”) to upgrade Accounts or grant other privileges. Promo Codes may have a validity period, conditions, and limits that vary by campaign. VieSpeak reserves the right to cancel or change the conditions of Promo Codes at any time.

VieSpeak is not responsible for any errors, delays, or failures of a Payment Provider. Any requests for refunds or payment adjustments may need to be submitted to the relevant Payment Provider, subject to that Payment Provider’s policies and applicable law.

You are responsible for any taxes or additional fees imposed by your payment method provider, the Payment Provider, or another third party in connection with your purchase.

6. Disclaimer of Warranties

The App and all Services, features, and content provided through the App are provided “as is” and “as available”, with all faults and without warranty of any kind, whether express, implied, or statutory.

To the maximum extent permitted by law, VieSpeak disclaims all warranties and conditions of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement, and any warranties arising out of course of dealing or trade usage.

VieSpeak does not warrant that the Services will be uninterrupted, secure, or error-free, that any errors will be corrected, or that the Services will be free of viruses or other harmful components. Although VieSpeak strives to keep the Services up to date and accurate, VieSpeak may rely on information provided by third parties and does not guarantee the accuracy or completeness of such third-party information.

VieSpeak does not warrant the accuracy, completeness, or usefulness of any information, translation, correction, suggestion, or other output generated or provided through the Services, and you acknowledge that such output may be inaccurate, incomplete, misleading, or inappropriate. You are solely responsible for evaluating and verifying any output before relying on it or using it in any context, especially for High-Risk Use Purposes such as, but not limited to:

• study;
• work;
• exams;
• immigration;
• legal;
• medical; or
• other important purposes.

Use the App at your own risk

VieSpeak is not responsible for any damages that may arise from the Services or your use of the Services. You understand and agree that you use the Services at your own discretion and risk, and that VieSpeak is not responsible for any damage to your property or any loss of data.

AI disclaimer

The App uses artificial intelligence and machine-learning technologies to generate responses, translations, corrections, suggestions, and other content (“AI Output”). AI Output is generated automatically and may be inaccurate, incomplete, misleading, offensive, or otherwise inappropriate. VieSpeak does not guarantee the accuracy, reliability, completeness, or usefulness of any AI Output, and you are solely responsible for how you use and rely on any AI Output.

In particular, you should not rely on AI Output without independent verification in any situation where inaccuracy could cause harm or significant consequences, especially for High-Risk Use Purposes including study or exams, immigration, legal, financial, medical, or safety-critical purposes.

VieSpeak provides CEFR level estimates and scores (Task Completion, Fluency, Expression) after each conversation session. These assessments are generated by AI and are for reference only for practice — they are not the result of an official exam or a recognized academic assessment, and should not be used for any official purpose.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL VIESPEAK, ITS AFFILIATES, EMPLOYEES, LICENSORS, OR SERVICE PROVIDERS BE LIABLE FOR ANY DAMAGES, WHETHER DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE, INCLUDING, WITHOUT LIMITATION, LOSS OF DATA, INCOME, PROFITS, OR GOODWILL, LOSS OF OR DAMAGE TO PROPERTY, AND THIRD-PARTY CLAIMS ARISING OUT OF YOUR ACCESS TO OR USE OF THE SERVICES, OUR CONTENT, OR ANY MEMBER CONTENT, REGARDLESS OF CAUSE, WHETHER BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE), INFRINGEMENT OF PROPERTY RIGHTS, PRODUCT LIABILITY, OR OTHERWISE.

THE FOREGOING WILL APPLY EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IF YOU BECOME DISSATISFIED IN ANY WAY WITH THE SERVICES, YOUR SOLE AND EXCLUSIVE REMEDY IS TO STOP USING THE SERVICES.

YOU WAIVE ALL CLAIMS ARISING OUT OF YOUR USE OF THE SERVICES. IF ANY PART OF THIS LIMITATION OF LIABILITY IS FOUND TO BE INVALID OR UNENFORCEABLE FOR ANY REASON, THEN OUR AGGREGATE LIABILITY WILL NOT EXCEED TWO MILLION DONG (2,000,000 VND).

THE LIMITATION OF LIABILITY HEREIN IS A FUNDAMENTAL ELEMENT OF THE BASIS OF THE BARGAIN AND REFLECTS A FAIR ALLOCATION OF RISK. THE SERVICES WOULD NOT BE PROVIDED WITHOUT SUCH LIMITATIONS, AND YOU AGREE THAT THE LIMITATIONS AND EXCLUSIONS OF LIABILITY, DISCLAIMERS, AND EXCLUSIVE REMEDIES SET OUT HEREIN WILL SURVIVE EVEN IF FOUND TO HAVE FAILED OF THEIR ESSENTIAL PURPOSE. THE FOREGOING DOES NOT APPLY TO LIABILITY ARISING FROM ANY FRAUD OR FRAUDULENT MISREPRESENTATION, OR ANY OTHER LIABILITY THAT CANNOT BE LIMITED BY APPLICABLE LAW.

8. Indemnification

All actions you take and information you provide on the Services remain your responsibility. You agree to indemnify, defend, and hold harmless VieSpeak and its affiliates, officers, directors, employees, agents, and licensors from and against any and all claims, demands, actions, proceedings, losses, liabilities, damages, costs, and expenses (including reasonable legal fees) arising out of or relating to:

• your access to or use of the Services;
• your User Content and Input, including any allegation that such content infringes, misappropriates, or violates any intellectual property, privacy, or other rights of any person or entity, or violates any applicable law; or
• your breach of these Terms.

VieSpeak reserves the right, at its own expense, to assume the exclusive defense and control of any matter that may be subject to indemnification by you, in which case you agree to cooperate with VieSpeak’s defense of that claim.

9. Termination and Suspension

VieSpeak may suspend or terminate your access to the Services (in whole or in part) at any time, with or without notice, if we reasonably believe that: (a) you have breached these Terms; (b) your use of the Services creates a security risk or may cause harm or liability to us, other users, or any third party; (c) we are required to do so by law or by a court or government authority; or (d) providing the Services is no longer commercially viable for us.

We may also stop providing the Services generally and terminate these Terms at any time. Unless we notify you otherwise, upon termination: (i) the rights and licenses granted to you under these Terms will immediately terminate; and (ii) you must stop using the Services and delete the App from your device.

You may stop using the Services at any time and may delete your account. You can delete your account at any time by opening the VieSpeak App, going to the “Settings” page, selecting “Delete Account,” and following the instructions to terminate your account.

Termination of your access to the Services, whether by you or by VieSpeak, will not affect any rights or obligations that have accrued up to the date of termination, including any payment obligations, limitations of liability, or dispute-resolution provisions, all of which will survive termination to the extent necessary to give them effect.

10. Updates to the Terms

We may change these Terms from time to time, for example to reflect changes to our services, business practices, or applicable law. When we make changes, we will post the updated Terms in the App or on our Site and update the “Last updated” date at the top of these Terms.

Where required by law, or if we make material changes that affect your rights or obligations, we will also provide you with additional notice (for example, by email or in-App notification) before the changes take effect.

Unless otherwise stated in the notice, the updated Terms will take effect as soon as they are posted. If you do not agree to the updated Terms, you should stop using the Services. Your continued use of the Services after the updated Terms take effect will constitute your acceptance of the changes.

11. Severability

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

12. Dispute Resolution

Dispute resolution by negotiation

Before filing any claim against VieSpeak, you agree to first contact us at support@viespeak.app and attempt to resolve the dispute informally. Please include your name, the email address associated with your Account, and a brief description of the dispute. If we are unable to resolve the dispute within thirty (30) days after we receive your notice, you or VieSpeak may pursue the claim in the manner permitted by these Terms.

Mediation and the courts

If the dispute cannot be resolved by negotiation, the parties agree to attempt to resolve the dispute through mediation at a reputable commercial mediation center in Vietnam before bringing the matter to court. If mediation is unsuccessful, the dispute will be brought for resolution before a competent court in Vietnam.

13. Governing Law

These Terms, and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with these Terms or their subject matter or formation, are governed by and construed in accordance with the laws of the Socialist Republic of Vietnam.

Subject to Section 12 (Dispute Resolution), you and VieSpeak agree that the competent courts of Vietnam will have jurisdiction over any dispute or claim arising out of or in connection with these Terms or your use of the Services.

14. Miscellaneous

Entire Agreement. These Terms (together with any policies or terms expressly incorporated by reference, such as our Privacy Policy) constitute the entire agreement between you and VieSpeak relating to the Services and supersede any prior or contemporaneous understandings or agreements, whether written or oral, relating to the Services.

No Waiver. Any failure or delay by VieSpeak in exercising any right or enforcing any provision of these Terms will not operate as a waiver of that right or provision or any other right or provision, nor will any single or partial exercise of any right preclude any other or further exercise of that right or any other right.

Assignment. You may not assign, transfer, or delegate any of your rights or obligations under these Terms, whether by operation of law or otherwise, without VieSpeak’s prior written consent. VieSpeak may assign, transfer, or delegate its rights and obligations under these Terms, in whole or in part, without restriction and without notice to you.

Relationship of the Parties. Nothing in these Terms is intended to create any partnership, joint venture, employment, agency, or fiduciary relationship between you and VieSpeak.

Force Majeure. VieSpeak will not be liable for any failure or delay in performance to the extent caused by circumstances beyond VieSpeak’s reasonable control, including acts of God, natural disasters, war, terrorism, riots, labor disputes, government actions, failures of telecommunications or internet services, or power outages.

Headings. Headings are for convenience only and do not affect the interpretation of these Terms.

15. Third-Party Services & App Stores

The Services may contain links to, or integrate with, third-party websites, content, services, or applications (collectively, “Third-Party Services”). Third-Party Services are provided by independent third parties and are not under VieSpeak’s control. VieSpeak does not endorse or assume any responsibility for any Third-Party Services, and your use of them is at your own risk and subject to the separate terms and privacy policies applicable to those Third-Party Services.
