AI Study Tutor (yourclasstutor.com) is a Chrome extension and phone page for studying with an AI tutor. It is made by Ethan Brothers, a college student. This policy explains what it handles, where it goes, and how to delete it.
In short: what you study is sent only to the tutor’s backend server, which uses OpenAI to answer. Nothing is sold, shared with advertisers, or used for anything except running the tutor for you. The extension never edits your documents.
Who runs what
- The extension runs in your Chrome browser and stores its data in Chrome on your computer.
- The backend is a server run by the extension’s owner (Ethan Brothers) that holds the AI key, keeps your notes library, and talks to the AI. You connect to it with a personal access password: one the owner gives you, or one made for you when you create a free account on the welcome page that opens after installing (sometimes the owner approves it first).
- OpenAI provides the AI model and the optional natural voice. The backend sends requests with “store: false”, so OpenAI does not keep the conversation for later retrieval. OpenAI’s API data policies apply: openai.com/policies/api-data-usage-policies.
What the extension handles
| Data | Why | Where it goes |
|---|---|---|
| Text you choose to send: text you copy or paste into the tutor, your messages, and your answers | So the tutor can answer you | The backend, then OpenAI. Saved in Chrome on your computer as study sessions (you can turn this off). |
| Your earlier chats, when you choose to use them (optional): a chat you bring into another one with “Past chat”, or, with “Search my past chats” on, bits of your saved chats that match your message | So the tutor can build on what you already went over | A chat you bring in is sent once to the backend and OpenAI to make a short summary, which is saved with that chat in Chrome and then sent with your messages. Searching happens in Chrome on your computer; only the matching bits are sent with your message. Nothing is kept on the backend. |
| Google Docs or Slides you add to your library | So the tutor can use your class notes | Downloaded through your own Google sign-in in an open Docs tab, then saved as text (and pictures, if you choose “Read images”) on the backend in your own library. Only the most relevant passages are sent to OpenAI with each message. |
| Files you upload (PDF, PowerPoint, Word, text): notes, textbooks, graded tests, practice tests | Your library, test reviews, practice tests | The backend, in your own library folder. A graded or practice test PDF is sent to OpenAI to read it. With “Read images”, each picture is sent to OpenAI once to be described. |
| The title and address of the Google Doc you’re in | To show which document you’re studying | Shown in the extension; sent with your message as context. |
| Your voice, when you click the microphone | Speech-to-text | Chrome’s built-in speech recognition, which Google provides. The extension never records or stores audio. |
| Reply text read aloud with the natural voice (optional) | Text-to-speech | The backend, then OpenAI’s text-to-speech. Audio clips are cached on the backend so repeats are free. |
| Courses, due dates, “What to work on” topics, study time, settings | Running the tutor and your dashboard | Chrome on your computer, and (with “Sync between my computers”, on by default) on the backend in your own folder, so your other computers and the phone page can show it. Turn Sync off in Settings → Your data to keep it on this computer only. |
| A Canvas calendar feed link (optional) | Due-date reminders | Stored in Chrome on your computer and used only to download your calendar from your Canvas site. |
| Creating an account (optional): the name and username you type, a random id the extension makes for this copy of the extension (not a hardware or MAC address), and the internet address the request came from | So the owner knows who has an account (and can approve the ones that need it), and to stop one computer from collecting several free accounts | The backend. The owner sees them on the admin page. Kept up to a year after the request is decided. |
| Sign in with Google (optional): your Google account’s name, email address, and Google’s id for the account. The extension doesn’t get access to your Google account or any Google data beyond these. | To make your account (or connect it to the one you have) and recognize you the next time you sign in with Google | The backend. The owner sees the email on the admin page. Kept while your account is connected; Disconnect in Settings → Account removes it. |
| Purchases (optional): the order number, what you bought, the checkout email, and the order note | To add the plan or credit you bought to your account | Read by the backend from the shop on yourclasstutor.com, which keeps a list of recent orders for the owner. Payment details stay with the shop’s payment provider and never reach the tutor. |
| Your access password | To connect to the backend | Stored in Chrome on your computer and sent to the backend with each request. |
| Your own OpenAI key (optional) | So your requests bill your own OpenAI account | Sent once to the backend, which stores it encrypted. It is never sent back to the extension. |
| Usage records: which features you used, token counts, and topic names | Monthly credit, limits, and costs | The backend. The owner can see these on an admin page: how much you use the tutor, which features, and the names of topics you study (for example a lesson topic or a “What to work on” topic). The owner’s admin page does not show your messages, the tutor’s replies, or chat titles. |
What the extension does not do
- It doesn’t read web pages or your browsing history. On Google Docs it reacts only when you copy text, and only while the side panel is open.
- It doesn’t read your clipboard in the background. It reads it only when you click “Paste copied text”, or, if “Auto-paste” is on, when you click into the side panel.
- It doesn’t edit your documents.
- It doesn’t show ads, track you across sites, or sell or share your data with anyone other than the services listed above.
- It doesn’t use your data to decide creditworthiness or for lending.
The phone page
The tutor’s server also has a page for phones (https://ai-tutor.synology.me:8543/m). It shows what’s already on the server for you (your synced due dates, topics, study time, and chats, plus your test reviews and study guides). You can also chat with the tutor there, which sends your messages to the backend and OpenAI like the extension does, and mark topics as “Got it”; both are saved to your synced data on the backend. Signing in there keeps your access password in that browser’s storage until you tap Sign out. It uses no cookies, ads, or trackers.
Optional features that use other sites
- Capture copies on every website / in-page badges: only if you turn them on, Chrome asks for access to all websites. Copy capture listens only for copy events (skipping password fields) and sends the copied text to your side panel. Badges draw a small card for reminders and don’t read the page.
- Study music: internet radio streams play from the stations’ own servers. If you pick Spotify, the extension opens the Spotify web player in a tab and presses its play, pause, next, and previous buttons, and reads the current song’s name. It reads nothing else on Spotify.
- Canvas: only the one Canvas site you connect, only to download your calendar feed.
How long data is kept, and deleting it
- Data in Chrome stays until you delete it: delete sessions, chats, or lessons in the extension, use “Delete all sessions” in Settings, or remove the extension.
- Library items, test reviews, practice tests, study guides, and video lessons stay on the backend until you delete them in the extension’s dashboard.
- Usage records are kept so monthly credit can be worked out, and for the owner’s cost tracking.
- To have everything about you deleted from the backend, including usage records, contact the owner (below).
Security
The backend accepts requests only from the Chrome extension and its own phone page, only with a valid access password, and only over HTTPS. Repeated wrong passwords are blocked. Saved OpenAI keys and access passwords are stored encrypted. No method of storing or sending data is perfectly secure, but these protections are in place.
Children
AI Study Tutor is meant for college students and is not directed to children under 13.
Changes
If this policy changes, the new version will be posted on this page with a new date.
