Information we collect

Account and security information: registration email, optional display name and avatar, password hash, email-verification and password-reset status, and timestamps recording your adult confirmation and cross-border consent. We do not store your login password in plain text.

Learning records: exercise answers, drafts, chapter progress and pass times, mastery assessments, review history, and placement-test results.

Learning feedback: the difficulty rating and optional comment you give at the end of a Practice or Use stage, and any objection you raise to how a Use task was marked, together with your latest Use answer and the per-requirement marking result that we keep so the marking can be checked. Please do not put personal information you would rather not share in the comment.

App feedback: the text and images you submit, your account, current page and submission time are saved and emailed to the operator at 1447596534@qq.com for follow-up, product improvement and manual reward review. Please avoid sensitive personal information.

AI Coach information: your conversations, generated feedback, and AI content reports you submit.

Orders and membership: if you purchase, we process the transaction identifier, membership term, price identifier, validity periods, payment and refund amounts, and processing records linked to your account to provide membership, reconcile payments, and handle refunds. Information at checkout is processed by Paddle under its privacy notice: https://www.paddle.com/legal/privacy.

Support email: your sender address, messages, attachments, and necessary email communication information sent to jacquaribtonoaq@gmail.com are processed through Google Gmail to answer inquiries and handle refund or privacy requests. Please provide only information needed for your request.

Website visits and preferences: Cloudflare Web Analytics collects page-visit and page-load performance metrics to understand website operations. Browser local storage remembers your chosen display language. This information is not used for targeted advertising.

Security and operations data: IP address, Turnstile token and necessary browser or network signals; request, exception and performance logs; and registration, verification, placement, chapter, AI-grading and review events linked to a hashed user identifier. We do not use this data for advertising.

Optional voice input and device permissions

We request microphone access when you choose voice input. You can continue typing without granting access and can revoke permission in your device or browser settings.

Android voice input first uses the recognition service enabled on your device. That service may send audio to its servers; the provider and processing rules depend on your device settings and that service's privacy notice. DOQUENCE receives the transcript for the learning answer or conversation input you initiate.

If system recognition is unavailable and server transcription is enabled for this service, the app records audio and sends it through our service to Microsoft Azure for transcription. Temporary recordings in the app's private cache are deleted after processing or cancellation. This does not describe the retention rules of the device recognition service or other recipients.

When saving a learning poster, you choose its destination through the system file picker. When sharing, you choose the receiving app. These actions do not grant us access to your entire photo library or file directory.

How we use information

To provide course learning, review, AI grading, and AI Coach features.

To assess learning progress and create personalized review and practice suggestions.

To adjust course difficulty based on learning feedback, and to check and correct the marking rules.

To show signed-in users leaderboard display names, avatars, completed-chapter counts, ranks, and timing information. Email addresses are not shown on the leaderboard.

To diagnose problems and understand product usage so we can improve the service.

To contact you when necessary about service changes or security matters.

Third-party processing and international transfers

This service uses Microsoft Azure and Cloudflare services outside mainland China. Before registration, the Cross-border Data Notice identifies the overseas recipients and explains the purposes, information involved, processing method, and how to exercise your rights: https://doquence.com/cross-border.html.

Support emails you choose to send are processed through Google Gmail and may be processed outside mainland China. Google privacy policy: https://policies.google.com/privacy. On purchase, Paddle independently processes payment, tax, fraud-prevention, and refund information as the transaction seller; this policy does not itself create a payment order.

We send only the information needed for verification email, security checks, AI grading, or AI Coach. We do not send your login password to the AI or bot-protection services.

Registration asks for separate consent to international processing needed for registration and core services. Without that consent, registration cannot be completed. Sending support email and purchasing are optional activities, not registration requirements.

Storage and security

Passwords are stored as hashes and are never stored in plain text.

We use reasonable technical and organizational safeguards, but no system can guarantee absolute security.

Your choices and rights

You can view your account information on the Account page.

You can delete your account at any time. Deletion removes your learning records, learning feedback and AI Coach conversations and cannot be undone.

App feedback and images are removed from the application database with your account. To request deletion of feedback email copies already sent, contact the operator by email.

You may also email jacquaribtonoaq@gmail.com to request access, a copy, correction, completion, or deletion of personal information, or to withdraw consent. We may first verify your identity.

Data retention

Account and learning master data is retained while your account remains active. Verification and password-reset codes expire after 10 minutes.

Product and operations logs are configured for 30-day retention, and database backups for 7-day retention. After account deletion, residual copies expire through the normal log or backup cycle.

Support emails and attachments are retained only as needed to handle the request, necessary follow-up, or legal obligations. Order and refund information is retained as required by applicable law. Deleting a learning account does not remove legally required transaction records; those records are restricted to fulfilling the relevant obligations.

Age requirement

The service is only available to adults aged 18 or older. You must confirm that you are at least 18 when registering.

Changes to this policy

Updates will be posted on this page. Material changes will be communicated in the app or by email.
