YouTube API Services Disclosure

Last updated: April 14, 2026

Ulearn AI uses YouTube API Services so that learners can turn videos they choose to watch on YouTube into flashcards and spaced-repetition review decks. This page explains what that means in practice, what we do and do not do with YouTube content, and how creators and users can exercise their rights. By using Ulearn together with YouTube content, you agree to the terms below in addition to the YouTube Terms of Service.

Required legal links

We do not remove videos from YouTube

Ulearn never downloads, copies, re-hosts, or redistributes YouTube videos. Playback always happens on YouTube’s own player — either by opening a YouTube link in a new tab, or via YouTube’s official embedded iframe player on our web app. The iframe player retains YouTube’s branding, controls, and ad delivery as required. If you cannot reach the source video on youtube.com (for example, because it was taken down or made private), Ulearn has no way to play it for you.

What YouTube data we access

When you watch a video on YouTube with the Ulearn extension enabled, or preview a public course derived from a YouTube video, we access the following via YouTube API Services:

Public metadata — the video’s title, channel name, description, category, and duration.
Captions / transcript text — when the video has captions and you are watching it, we read the transcript for the single active video so it can be turned into practice questions.
Video IDs and thumbnails — so we can link back to the source video on youtube.com and show a preview image that also serves as a play-through link.

We do not access your YouTube account profile, subscriptions, watch history beyond the current tab, private videos or playlists, comments, likes, or any social-graph data. We do not use Ulearn to download or save YouTube video content.

Transformative use — quiz questions, not copies

Ulearn uses an AI model operated by a third-party provider to read the transcript of a video you are watching and produce a short set of multiple-choice questions about the ideas in that video. Those questions are a transformative, educational summary; they are not a transcript reproduction, a substitute for watching the video, or a rehosting of YouTube content. Each generated quiz retains a link back to the source video and timestamps where applicable.

We do not train AI models on YouTube content

Per YouTube’s API Services Terms of Service, Ulearn does not fine-tune, train, or otherwise improve any machine-learning model using YouTube API data. Transcript text is sent to the AI model solely to produce a single quiz for the active video, and is not retained after the quiz is generated. Ulearn has no training pipeline, no fine-tuning workflow, and no model weights that it owns or updates.

Caption / transcript caching

Ulearn’s handling of caption data is stricter than what YouTube’s caching policy allows:

Transcript text is sent to the AI provider to generate questions, then discarded from our systems.
Only the resulting quiz questions (which are derivative content authored by the AI, not the original caption text) and minimal video identifiers (title, channel, video ID) are retained inside your personal Ulearn account.
Ulearn does not build a searchable transcript library, does not make raw captions available to other users, and does not re-serve transcript text in any public-facing surface.

OAuth authorization (Chrome extension only)

The Chrome extension requests the https://www.googleapis.com/auth/youtube.force-ssl OAuth scope in order to read caption tracks that YouTube’s public endpoints don’t always expose. This authorization is granted by you through Google’s consent screen and is used solely to fetch captions for the video you are currently watching. It is never used to post, comment, subscribe, rate, or modify anything on your YouTube account.

Creator takedown — content removal requests

If you are a YouTube creator and do not want Ulearn users to generate or share quizzes derived from your videos, email academysiegel@gmail.com with:

Your YouTube channel name or URL.
The specific video URL(s) you want excluded, or a note that you want all of your channel’s content excluded.
Confirmation that you are the rightsholder or an authorized representative.

We will remove any derived course content associated with the listed videos from our public directory and block future quiz generation for those videos, typically within seven business days. This process is available to creators regardless of whether the original upload remains on YouTube.

DMCA and other intellectual-property claims

For rights-holder claims outside of YouTube (copyright, trademark, etc.), send a takedown notice including the material at issue, the infringing URL on ulearnai.org, your contact information, a good-faith statement, and a signature (physical or electronic) to academysiegel@gmail.com. We will act on valid notices in a timely manner and may contact the user who submitted the material before removing it where appropriate.

Your rights and controls

Revoke Ulearn’s access to your Google / YouTube account at Google’s Third-Party Apps & Services page. Revoking access removes the OAuth grant used by the Chrome extension for caption fetching.
Delete your Ulearn data by signing in to ulearnai.org/app, opening the account menu, and using Clear My Data. This removes every deck, card, and review record associated with your account.
Request a data export or further deletion by emailing academysiegel@gmail.com.
Report YouTube content via YouTube’s own reporting tools.

Children’s privacy

Ulearn is not directed at children under the age of 13. If you are a parent or guardian and believe your child has used Ulearn, contact us and we will delete any associated data.

Changes to this disclosure

We may update this page as the service evolves. The “Last updated” date at the top reflects the most recent change. Material changes will be announced in the footer of ulearnai.org.
