Private Prep Diagnostic Navigator is a Chrome extension that adds keyboard shortcuts for navigating between questions on diagnostic test review pages at tests.privateprep.com.
Data collection: none. This extension does not collect, store, transmit, sell, or share any user data of any kind. It has no analytics, no tracking, no accounts, and makes no network requests of its own.
How it works. The extension runs a single content script only on pages under tests.privateprep.com. The script listens for keyboard input on those pages and activates navigation links that already exist on the page — the same links a user would click manually. Nothing the script reads (key presses, page content) ever leaves the browser tab.
Permissions. The extension requests access to tests.privateprep.com only. This host permission exists solely so the content script can run on those pages and perform the navigation described above.
Third parties. No data is shared with third parties, because no data is collected.
Changes. If this policy ever changes, the updated version will be posted at this URL.
