Quizik is a Chrome extension that helps students study quizzes. This page describes what data the extension and its hosted backend collect, how it is used, and who it is shared with.
What we collect
Visible page text and a screenshot of the current tab — collected only when you actively ask the assistant a question. The content script reads only visible elements (password fields, hidden inputs, scripts, styles, cookies, and browser storage are excluded).
Your chat messages — sent with each request as part of the conversation history.
Your IP address — visible to Cloudflare for routing, rate limiting, and abuse prevention. We do not store it.
What we do NOT collect
Account information (Quizik has no accounts yet).
Browsing history outside of the moments you ask a question.
Cookies, browser storage, or page data we do not explicitly need.
Analytics, tracking pixels, or third-party trackers.
How your data is used
When you send a message, the extension forwards the question, screenshot, and chat history to our Cloudflare Worker, which proxies the request to OpenAI's API. OpenAI returns a response that is shown to you in the chat panel. The request and response are not persisted on our backend.
Third parties
OpenAI — model inference. Your question and screenshot are sent to OpenAI's API. OpenAI's data usage is governed by their API Data Usage Policies; in particular, API inputs are not used to train models by default.
Cloudflare — request routing, edge compute, and rate limiting. Cloudflare may retain standard request logs for a short period as described in their Privacy Policy.
Local storage
The extension uses chrome.storage.local to remember your chosen UI language and cache localization files for 24 hours. Chat history exists only in the popup's memory and is discarded when the popup is closed. Nothing in chrome.storage.local leaves your device.
Children
Quizik is not directed at children under 13. We do not knowingly collect data from children.
Your choices
You can stop using Quizik at any time by removing the extension from chrome://extensions. This deletes all local storage data associated with it.
Changes
If we change this policy, we will update the "Last updated" date at the top. Substantive changes will be announced in the extension's release notes.
