AI Understanding 是一个致力于开放教育的非营利组织。我们收集负责任地运营、提高可靠性以及与选择听取我们意见的人沟通所需的最少信息。

What we collect

  • 用于订阅时事通讯的电子邮件地址。
  • Account information (name and email) when you create an account.
  • 链接到您的帐户的书签和首选项。
  • Anonymous visit statistics for every visitor: pages viewed, the referring site and campaign tags, your country (no city or region), device and browser type, and actions such as starting a quiz. These are counted without cookies or browser storage and are not linked to you.
  • Only if you choose “Allow measurement”: fuller analytics that recognize a returning browser, link visits to your account when you are signed in, and record a small sample of visits as session replays with form inputs masked.
  • 您通过联系表格或支持请求发送的消息。

How we use information

信息用于：

  • 提供请求的更新和新闻通讯。
  • 提高教育内容质量和网站性能。
  • 回复查询、更正和支持请求。
  • 维护操作安全并防止滥用。

AI tutor NOVA data

When you use the AI tutor NOVA, the messages needed to answer your question are sent to the live AI provider configured for the service. AI Understanding does not write raw tutor conversations to its learner database. For signed-in learners, quizzes can create an aggregate skill record containing a score, attempt count, and review date so we can recommend practice; it does not contain the question or answer text. Your saved tutor conversation is kept in your browser's local storage until you clear it or remove the site's stored data.

Please do not share passwords, financial information, medical details, confidential school records, or other sensitive personal information with the tutor. Organizations deploying the tutor for students should contact us before use so appropriate contracts, access controls, retention rules, and educational privacy requirements can be reviewed.

What we do not do

  • 我们不出售个人信息。
  • 我们不运营第三方广告跟踪市场。
  • 我们不会将个人数据用于不相关的商业分析。

Third-party services

We use trusted service providers for email delivery, authentication, donation processing, site analytics (PostHog; Ahrefs Web Analytics, which uses no cookies; and, only with your permission, Microsoft Clarity), ad measurement (Google Ads; and, only with your permission, X), and error and performance monitoring (Sentry). These providers are expected to follow strong security and privacy standards.

分析

Every visit is counted with PostHog in a cookieless mode: nothing is stored on your device, you are not identified, and no profile or session recording is made. PostHog tells visits apart with a one-way hash of your IP address, browser user agent and our domain using a secret that changes daily, so the same browser cannot be recognized across days. For these visits only your country is recorded, taken from the country code our network provider, Cloudflare, attaches to each request; no city or region is recorded. Analytics requests pass through our own server, which forwards your IP address to PostHog for that daily hash and, only after you choose “Allow measurement,” to estimate approximate location. Cookies and identifiers for fuller analytics are used only after you choose “Allow measurement,” and you can withdraw that at any time. Account events such as sign-ups, sign-ins and payments are recorded by our server as part of running your account.

Error and performance monitoring

We use Sentry, operated by Functional Software, Inc., to find errors and understand site performance. Sentry does not record session replays. In your browser, Sentry loads only after you choose “Allow measurement.” Error reports from our servers and edge runtime are part of operating the site. Those reports do not include cookies, authorization headers, request bodies, or user information. In production, about 2% of performance traces are sent. Server warning and error log lines are also sent to Sentry after emails, tokens, and other sensitive text are removed. Sentry processes this data in the United States. See Sentry 的隐私政策.
