隐私政策

What we collect

• 账户。 我们保存显示名称和学习目标，以及你用于登录的账号信息，包括你提供并验证的邮箱、Google 身份或微信服务号下的账号标识（OpenID）。历史手机与微信记录可能继续保留，以保留既有记录和权益。
• Practice data: your answers, scores and wrong-book entries, linked to your account.
• Voice recordings: audio you record for speaking tasks, stored to score them.
• Payment data: handled by the enabled provider (Stripe or AlphaPay); we store order references, membership tier, amount and payment status — never card numbers.

How AI scoring processes your work

When you submit a speaking assessment, recordings are sent to Microsoft Azure Speech to produce pronunciation, fluency and content scores. Essays are sent to a large language model provider for trait-based feedback. Recordings and texts are used to score your attempt and are not used to train models by us.

How long we keep things

• Voice recordings: stored for scoring and controlled recovery. Automatic retention cleanup has not yet been enabled; a 90-day deletion schedule is not currently guaranteed.
• Score data (numbers, dimensions, feedback): kept with your account history.
• Uploaded real-test score reports (if you submit them for calibration): calibration uploads are not currently offered. Retention terms will be published before this feature opens.

Deleting your account

Profile Settings offers Delete Account with explicit confirmation. It deactivates your account and revokes sign-in sessions on all devices. Historical answers, scores, entitlements, orders and accounting records are retained. This is not permanent data erasure. A verified request and retention review are required before changes to historical records; no automatic erasure deadline is promised by this preview.

Public sharing and invitations

Clicking Share creates a public link to the question type, scores, scoring dimensions, scoring version, dates and speaking recording. Links expire after 7 or 30 days and can be revoked from your account. We record course entry views and interactions to understand interest. Verified identity and invitation records prevent duplicate trial rewards.

Optional metrics and practice drafts

Anonymous product metrics are off until you opt in using the control on this page, and server collection is disabled in this preview. When enabled, we record visits, task starts, successful submissions and logins using a random tab identifier stored as a hash. These events contain no answers, recordings, phone numbers or account ID. Raw events expire after 30 days and daily totals after 180 days. You can withdraw consent on this page; this stops new collection and clears the tab identifier.

Text and selection drafts stay in this browser tab for up to one hour and are separated by account, exam and question version. They are not uploaded as drafts; recordings are excluded. Submission, signing out or switching accounts clears the relevant drafts. Closing the tab ends the session; blocked storage leaves practice usable without restoration.
