Terms and Conditions of Service

  1. General
    Artlexis websites (“Websites”), mobile applications (“Apps”), and related services (together with the Websites and Apps, the “Service”) are operated by EUP TECHNOLOGY.,JSC. (“EUP” “us,” or “we”). Access and use of the Service is subject to the following Terms and Conditions of Service (“Terms and Conditions”). By accessing or using any part of the Service, you represent that you have read, understood, and agree to be bound by these Terms and Conditions including any future modifications. EUP may amend, update, or change these Terms and Conditions. If we do this, we will post a notice that we have made changes to these Terms and Conditions on the Websites for at least 7 days after the changes are posted and will indicate at the bottom of the Terms and Conditions the date these terms were last revised. Any revisions to these Terms and Conditions will become effective the earlier of (i) the end of such 7-day period or (ii) the first time you access or use the Service after such changes. If you do not agree to abide by these Terms and Conditions, you are not authorized to use, access, or participate in the Service.
  2. Description of Website and Service
    The Service allows users to access and use a variety of educational services, including learning or practicing Artlexis, EUP may, in its sole discretion and at any time, update, change, suspend, make improvements to or discontinue any aspect of the Service, temporarily or permanently.
  3. Acceptable Use of the Services
    You are responsible for your use of the Services, and for any use of the Services made using your account. Our goal is to create a positive, useful, and safe user experience. To promote this goal, we prohibit certain kinds of conduct that may be harmful to other users or to us. When you use the Services, you must comply with our guidelines:

The forum has a large number of users from all over the world, from many different cultures and with many different language levels, but we all have the same goal: to learn. Curiosity, love of learning and cultural knowledge are what we should share. Respect others as others respect you.

We are all in this together. Learning a language is not easy and requires a lot of willpower and determination. If someone uses incorrect grammar or has a question that you can answer, help them in a kind and gentle way. Being harsh and hostile will not help anyone learn anything. If you cannot stay calm and be friendly, please do not engage in answering.

A language can have many words, many sounds, and many ways to say the same thing. That is the wonderful diversity of language. Come to the discussion with an open mind and attitude.

We care about your safety. Learning a language involves a lot of communication, but be careful about posting personal information here to avoid being taken advantage of by bad actors. Personal information can include your phone number, age, address, times you'll be home, school name, email, or any other personal information that could put your privacy at risk. Simply put: don't overshare. Sharing and encouraging others to share personal data can lead to your post, and possibly your account, being taken down.

We do not tolerate content that:

Artlexis is a safe learning environment for everyone. Harassment and hurtful behavior will not be tolerated. Using icons, names, and comments to harass, impersonate someone, or make sexually explicit comments about someone—all of which are considered violations of Artlexis rules. The same goes for nudity, inappropriate avatars, and usernames. As stated in our terms , Artlexis reserves the right to replace images or remove accounts at our discretion. First rule: if you are making someone feel attacked or hurt, you should stop doing so. We take reports of inappropriate behavior seriously and may delete your account without notice once our team has confirmed your actions.

Artlexis requires honesty in learning. If you use userscripts to cheat or steal other users' information, affecting Artlexis systems and data as well as the learner community, your account will be banned.

Comments that are inflammatory, obscene, or unrelated to the topic at hand will not help the learning process. Neither will profanity or swearing. Please keep these out of the forum.

We will remove any content that violates the spirit of these guidelines and you risk losing some or all of your access to Artlexis without notice. By following these guidelines, we contribute to a fun and productive learning community.

  1. Additional Terms
    Some of our Services have additional terms and conditions (“Additional Terms”). Where Additional Terms apply to a Service, we will make them available for you to read through your use of that Service. By using that Service, you agree to the Additional Terms.

  7. In-App Purchases
    Automatic Renewal
    If you purchase an auto-renewing periodic subscription through the Service, your Artlexis account will be billed continuously for the subscription until you terminate it as set forth below. After your initial subscription period, and again after any subsequent subscription period, your subscription will automatically renew for an additional equivalent period. If you do not wish your subscription to renew automatically, or if you want to change or terminate your subscription, you will need to log in to your Artlexis account and follow instructions to terminate or change your subscription, even if you have deleted your account.

    All payments are nonrefundable. There are no refunds or credits for Virtual Items or partially used membership periods. However, EUP may grant refunds or credits on a case-by-case basis at our sole discretion. EUP’s grant of a refund or credit in one instance does not obligate EUP to provide a refund or credit in the future, under any circumstances. If you cancel your periodic subscription to a paid service, you will continue to have access to the service through the end of your current billing period.
  10. Third-Party Links, Sites, and Services

Access and use of the service may be unavailable during periods of peak demand, system upgrades, malfunctions or scheduled or unscheduled maintenance or for other reasons. Some jurisdictions do not allow the exclusion of implied warranties, so the above exclusion may not apply to you.

    To the maximum extent permitted by applicable law, in no event will EUP be liable to you or any third party claiming through you (whether based in contract, tort, strict liability or other theory) for indirect, incidental, special, consequential or exemplary damages arising out of or relating to the access or use of, or the inability to access or use, the service or any portion thereof, including but not limited to the loss of use of the service, inaccurate results, loss of profits, business interruption, or damages stemming from loss or corruption of data or data being rendered inaccurate, the cost of recovering any data, the cost of substitute services or claims by third parties for any damage to computers, software, modems, telephones or other property, even if EUP has been advised of the possibility of such damages. to the maximum extent permitted by applicable law, EUP’s liability to you or any third party claiming through you for any cause whatsoever, and regardless of the form of the action, is limited to the amount paid, if any, by you to EUP for the service in the 12 months prior to the initial action giving rise to liability. This is an aggregate limit. The existence of more than one claim hereunder will not increase this limit.
  13. Termination
    EUP may terminate your access and use of the Service immediately at any time, for any reason, and at such time you will have no further right to use the Service. You may terminate your EUP account at any time by following the instructions available through the Service. Sections 1, 6, 8, and 10-28 of these Terms and Conditions shall survive any termination.
  14. Proprietary Rights in Service Content and Activity Materials

For example, if you obtained a prepaid subscription to Artlexis by redeeming a Promotion Code provided by your employer, your employer may terminate your prepaid subscription if your employment ceases.

For clarity, only copyright infringement notices should go to our Copyright Agent. You acknowledge that if you fail to comply with all of the requirements of this section your notice may not be valid.
If you believe the content that was removed (or to which access was disabled) is not infringing, or that you have the authorization from the copyright owner, the copyright owner's agent, or pursuant to the law, to post and use such content, you may submit a counter-notice to the address listed above containing the following information:

We will not forward the counter-notification to any party other than the original claimant.
After we send out the counter-notification, the claimant must then notify us within 10 days that he or she has filed an action seeking a court order to restrain you from engaging in infringing activity relating to the content that was removed or disabled.

  1. Governing Law
    These Terms and Conditions shall be governed by and construed under the laws of Vietnam, excluding any conflict of laws provisions, regardless of your country of origin or where you access the Service.
  2. Choice of Forum
    Subject to Section 24 (Dispute Resolution & Arbitration), all judicial proceedings relating to or arising out of these Terms and Conditions or the Service shall be brought in the People's Court in Hanoi, Vietnam.

An individual party must be personally present at this settlement conference, and an entity party must be present at this settlement conference through an employee with settlement authority, though both parties may bring counsel as well. Arbitration shall be initiated only if no settlement can be reached at this settlement conference.
    The arbitration shall be conducted by a single arbitrator and administered by the Vietnam International Arbitration Centre (“    VIAC”) and the provisions of this section. Where they conflict, the provisions of this section shall take precedence over any VIAC Rules. If the VIAC is unavailable to conduct an arbitration, the parties shall arbitrate through another mutually agreed upon organization or on an ad hoc basis according to the rules in this section. The arbitration shall be conducted in the English language.
    If a claim is within the jurisdiction of a small claims court, either party may choose to have the case heard in the small claims court on an individual basis, instead of arbitration.
    If you do not want to arbitrate disputes with EUP and you are an individual, you may opt out of this arbitration agreement by sending an email to [email protected] within 30 days of the day you first access or use the Service.
    Notwithstanding the above, either party may apply for and obtain non-monetary, injunctive remedies or urgent relief in court without engaging in any arbitration or informal dispute resolution process.
