We will assist you in locating or restoring your course access.

5. Educational Content

Qingsen EDU provides educational content for learning and practice purposes.

Our courses and learning materials are intended to support English vocabulary development and language practice. Results may vary depending on the student’s age, current English level, study habits, consistency, and other individual factors.

Qingsen EDU does not guarantee that a student will achieve a specific grade, test score, fluency level, academic result, or other particular outcome.

Students are encouraged to use the learning materials consistently and follow the recommended learning process.

6. Student Use of Course Materials

Purchased course materials are provided for the personal educational use of the purchaser or the student for whom the course was purchased.

Unauthorized distribution or sharing may result in suspension or termination of course access without refund, subject to applicable law.

We may occasionally update, improve, modify, replace, or discontinue certain course materials, exercises, features, or website functions.

These changes may be made to:

• Improve educational quality

Where reasonable, we will attempt to maintain substantially similar educational value for purchased courses.

Qingsen EDU is not responsible for problems caused solely by a customer’s device, internet connection, browser, operating system, email provider, or other third-party technology.

If you experience a technical problem with our website or course platform, please contact us so that we can investigate and provide reasonable assistance.

• Course description
• Price
• Access period
• Any applicable subscription terms
• Refund or cancellation conditions

Once payment has been successfully processed, digital course access may be provided according to the applicable product terms.

11. Refunds and Cancellations

If you experience a problem with your purchase, such as:

• You cannot access a purchased course
• You received incorrect access information
• A technical issue prevents reasonable use of the purchased service
• You were charged incorrectly

please contact us at connect@qingsenedu.com.

12. Subscription Services

If Qingsen EDU offers subscription-based products, the applicable subscription price, billing frequency, renewal terms, and cancellation procedures will be presented before purchase.

Customers are responsible for reviewing these details before completing a subscription purchase.

If you wish to cancel a recurring subscription, you should follow the cancellation instructions provided with the service or contact customer support.

Cancellation of a subscription generally prevents future charges but does not necessarily result in a refund for a previous billing period, except where required by applicable law or provided under our refund policy.

From time to time, Qingsen EDU may offer promotional pricing, discounts, coupons, or special offers.

Unless otherwise stated:

• Promotional offers may have expiration dates

14. Third-Party Services

Qingsen EDU may rely on third-party services to provide certain functions, including payment processing, email delivery, website hosting, analytics, security, and other technical services.

Third-party services may have their own terms and privacy policies.

Qingsen EDU is not responsible for independent failures, interruptions, or policy changes made by third-party service providers, although we will make reasonable efforts to resolve issues affecting our services.

Unless otherwise stated, the Qingsen EDU website, course materials, educational content, text, graphics, logos, videos, exercises, designs, and other original materials are owned by or licensed to Qingsen EDU and are protected by applicable intellectual property laws.

Purchasing a course grants you a limited right to access and use the purchased educational materials for their intended personal educational purpose.

A purchase does not transfer ownership of the underlying intellectual property.

18. Children’s Use of Our Services

Some Qingsen EDU courses may be designed for students under the age of 18.

Where a service is intended for children or minors, a parent or legal guardian should review the applicable purchase and service terms.

By using our services, you acknowledge that you have reviewed our Privacy Policy.

20. Disclaimer of Educational Results

Qingsen EDU provides educational tools and learning resources but does not guarantee specific academic or language-learning results.

Individual results depend on many factors, including:

• Student participation
• Learning frequency
• Existing English ability
• Practice time
• Individual learning preferences
• Age and educational background
• Use of the course materials

Our courses should be considered educational support rather than a guarantee of any particular academic or professional outcome.

Nothing in this Service Policy is intended to exclude or limit any liability that cannot legally be excluded or limited under applicable law.
