Privacy Policy

Last updated: October 19, 2026

This Privacy Policy explains how TeacherGPT ("TeacherGPT," "we," "us," or "our") collects, uses, discloses, retains, and lets you control information when you use the TeacherGPT app in ChatGPT, visit a TeacherGPT lesson link, or create a TeacherGPT website account.

1. Service and controller

TeacherGPT turns captioned YouTube videos into interactive multiple-choice lessons. TeacherGPT is operated by Puzzicle Pte Ltd. Privacy questions and deletion requests may be submitted through our secure support form.

2. Information we collect

2.1 Information you provide through ChatGPT

• YouTube video URLs or 11-character video IDs;
• an optional lesson title;
• quiz preferences, including question count, difficulty, and focus topics;
• generated quiz questions, answer choices, correct-answer indexes, timestamps, and explanations passed to the save tool;
• lesson IDs supplied when retrieving or deleting a lesson;
• support-form details, including your reply email, optional name and lesson ID, request type, and message.

Do not submit confidential information or personal data about yourself or others. TeacherGPT does not require names, email addresses, payment data, credentials, government identifiers, health information, or precise location.

2.2 Information obtained from YouTube

For the video you select, TeacherGPT receives publicly available caption text and timing segments from Coursarium, together with the associated YouTube video ID and URL.

2.3 Generated information and tool outputs

TeacherGPT creates a random lesson ID, draft and saved-lesson status, lesson title, video metadata, transcript-derived quiz content, question count, creation timestamps, and an unlisted lesson URL. Retrieval tools return lesson metadata and the unlisted link. The deletion tool returns whether the specified lesson was deleted.

2.4 Technical and operational data

Our web server and hosting infrastructure may process IP address, request time, requested path, HTTP status, user agent, request identifiers, and security or error logs. MCP session identifiers are held temporarily in server memory. We do not use advertising cookies or build advertising profiles.

2.5 Website accounts, My Lessons, and the AI lesson editor

Creating a TeacherGPT website account is optional. If you sign in on teachergpt.com we collect:

• Your email address, used only to send one-time sign-in links and to identify your account. Sign-in links expire after 15 minutes and can be used once.
• A session cookie (tg_session), a strictly necessary, HttpOnly cookie that keeps you signed in for up to 30 days. We do not use advertising or analytics cookies.
• Your My Lessons list: the lesson IDs, titles, video IDs, and question counts of lessons you open or add while signed in, and when you saved them.
• Lesson ownership and sharing settings: the first signed-in person to open a lesson link becomes its owner. We record the owner, whether others may edit the original or must make a copy, and which lesson a copy came from.
• Lesson edits: changes you save to a lesson's title, questions, answers, timestamps, and explanations. Saved changes are visible to anyone with the lesson link.

When you use the AI lesson editor, your chat messages, the current lesson draft, and the video transcript are sent to OpenAI's API to generate the edits you request. We do not store your editor chat messages after the response is returned.

2.6 Answers to short-answer and open questions

When a learner answers a short-answer or open question, the question, its answer key, and the learner's answer are sent to OpenAI's API to check the answer. Short answers that exactly match an accepted answer are checked without being sent. We do not store learners' answers; we keep only a temporary, anonymous fingerprint of each answer and its result in server memory so identical answers are not checked twice. Please don't enter personal information in answers.

3. Why we use information

• retrieve captions for the YouTube video you request;
• prepare and generate the quiz according to your preferences;
• save, display, retrieve, share through an unlisted URL, and delete lessons;
• sign you in, keep your My Lessons list, record lesson ownership and sharing settings, and save your lesson edits;
• generate lesson edits you request in the AI lesson editor;
• operate MCP sessions and respond to tool requests;
• protect the service, prevent abuse, diagnose errors, and maintain reliability;
• comply with applicable law and enforce our Terms.

We do not sell personal data, use lesson content for targeted advertising, or use lesson content to train our own AI model.

4. Tool-by-tool data use

• process_video: sends the selected YouTube video ID to Coursarium, receives captions, and stores a temporary transcript draft.
• create_quiz: reads the draft transcript and returns it with the selected quiz preferences to ChatGPT so ChatGPT can generate questions; it does not change stored data.
• save_lesson: stores the transcript, video metadata, lesson title, questions, answers, explanations, and timestamps, then returns an unlisted lesson URL.
• get_lesson: uses the supplied lesson ID to return the matching lesson title, question count, video ID, and unlisted URL.
• delete_lesson: permanently deletes the lesson, transcript, questions, and answer options associated with the supplied lesson ID.

5. Who receives information

• OpenAI: receives and processes your ChatGPT conversation, tool inputs, and tool outputs under OpenAI's policies and your ChatGPT settings.
• OpenAI (API): if you use the AI lesson editor, receives your editor messages, the lesson draft, and the video transcript to generate edits; when a learner answers a short-answer or open question, receives the question, answer key, and answer to check it. Both are processed under OpenAI's API data-usage policies.
• Coursarium: receives the YouTube video ID solely to retrieve the publicly available transcript requested through process_video.
• TeacherGPT support team: receives support-form submissions to respond to requests.
• Email delivery: your email address is processed by our mail server to deliver sign-in links.
• Hosting and infrastructure providers: process stored lesson data and operational logs as needed to host, secure, and deliver TeacherGPT.
• People you choose: anyone to whom you provide an unlisted lesson URL can access that lesson. TeacherGPT does not publish a directory of saved lessons.
• Authorities or transaction parties: information may be disclosed when required by law, to protect rights and security, or as part of a merger, acquisition, or asset transfer subject to appropriate safeguards.

We do not sell or rent lesson data. You should also review OpenAI's Privacy Policy, and Google/YouTube's Privacy Policy.

6. Retention

• Draft transcripts are scheduled for deletion after 24 hours.
• Saved lessons remain until deleted with delete_lesson or until the service is discontinued.
• In-memory MCP sessions expire after 30 minutes of inactivity.
• Website accounts, My Lessons lists, and ownership records remain until you delete your account. Sign-in links expire after 15 minutes; sign-in sessions after 30 days.
• Routine server and security logs are retained for up to 30 days unless a longer period is required to investigate abuse, resolve an incident, or comply with law.
• Support requests and replies are retained for up to 24 months for follow-up, dispute handling, and service improvement, unless earlier deletion is required or a longer period is legally necessary.

7. Your controls and choices

• Choose which YouTube video and quiz preferences to provide.
• Do not share an unlisted lesson URL with people who should not see the lesson.
• Ask TeacherGPT to permanently delete a lesson and provide its lesson ID.
• Use the support form to request access, correction, or deletion where applicable. Include the lesson ID, but do not email sensitive information.
• Manage or delete your ChatGPT conversations using OpenAI's privacy controls.
• Delete your TeacherGPT website account at any time from My Lessons. This removes your email, sessions, and My Lessons list, and releases ownership of your lessons; the lessons themselves remain available at their links.

If you use TeacherGPT without a website account, we do not collect identity information and may be unable to associate a lesson with you unless you provide its unlisted lesson ID. We may request reasonable verification before acting on a privacy request.

8. Security

We use HTTPS in production, random UUID lesson identifiers, limited tool inputs, restricted cross-origin access, request-size limits, and server security headers. Unlisted links are not authentication; anyone with the link can view the lesson. No internet service is completely secure.

9. International processing

TeacherGPT, OpenAI, Coursarium, and infrastructure providers may process information in countries other than yours. Applicable contractual and legal safeguards are used where required.

10. Children's privacy

TeacherGPT is not directed to children under 13. Users must meet ChatGPT's age requirements. Parents and educators should supervise minors and avoid submitting personal information about children.

11. Changes

We may update this policy as the service or legal requirements change. We will post the revised policy here and update the date above. Material changes will be highlighted when reasonably possible.
