About the service
DOQUENCE provides English courses, exercises, review, and AI-assisted learning, and currently offers a free Beta. Purchase availability is shown on the membership page; no payment is taken before purchases open.
We may change or suspend parts of the service for maintenance, security, or legal reasons. If a change affects the main benefits of a purchased membership, we will provide notice as required by law and address it through continued performance, alternative arrangements, refunds, or other appropriate remedies. We will not arbitrarily erase learning records for testing.
Membership and payments
When paid access opens, free accounts can open any 2 chapters, use 5 AI gradings in total, and view Library words linked to their chapters. Members get every chapter, unlimited AI grading, AI Coach, and the full Library. These launch allowances do not change the current free Beta rules before launch.
The official membership prices are CNY 39 for a monthly pass and CNY 199 for a yearly pass. The order amount, currency, and taxes are shown before payment.
Membership is a one-time payment: a monthly pass lasts 1 month and a yearly pass lasts 12 months. Nothing renews automatically, and buying again while a member extends the current period.
For transactions checked out through Paddle, Paddle acts as the Merchant of Record and authorized reseller and handles applicable sales tax or VAT as shown at checkout. Our company provides the DOQUENCE learning service. Paddle buyer terms: https://www.paddle.com/legal/buyer-terms.
Refunds: you can ask for a full refund within 7 days of purchase; after that, an approved refund is proportional to the days not yet used. The full rules are at https://doquence.com/refund.html.
The refund policy does not restrict non-excludable rights under applicable law or Paddle buyer terms, or remove a more favorable refund commitment we have made.
When a membership ends or is refunded, your account returns to the free plan. Chapters you finished remain available for review.
