Nudge — LeetCode Guide · Last updated: 2026

What we store, and where

All extension data is stored locally in your browser using Chrome's chrome.storage.local API. It never leaves your device. This includes:

• Your Gemini API key (entered by you in the extension popup)
• Cached problem analyses, hints, and revealed solutions
• Your progress: which problems you've attempted, how many hints you've used, time spent, approaches explored, solved status
• UI preferences: panel width, height, font level, side (left/right), theme, hook position

You can wipe all of this at any time from the popup's 📈 Dashboard tab → 🗑️ Reset all progress, or from chrome://extensions by removing the extension.

What we send to third parties

The extension sends the text of the LeetCode problem you're viewing (title, description, examples, constraints, tags) to Google Gemini via the API, using your own API key. This is the only network call the extension makes.

Google's handling of this data is governed by their own Gemini API Terms and Privacy Policy. We do not receive, log, or have access to anything Google sees or sends back.

What we don't do

• ❌ No accounts or sign-up
• ❌ No analytics, tracking pixels, or telemetry
• ❌ No third-party scripts or cookies
• ❌ No advertising
• ❌ No cloud sync between devices
• ❌ No reading or modifying pages other than LeetCode problem pages
• ❌ No sharing or selling your data — we have nothing to share

Permissions, explained

• storage — used to keep your API key, preferences, and progress in chrome.storage.local.
• activeTab — lets the extension know which tab you have open, used by the popup to detect if you're on a LeetCode problem page.
• scripting — used to inject the side panel into LeetCode problem pages.
• host_permissions: leetcode.com/* — the extension runs only on LeetCode pages. It does not run on any other website.

Security

Your Gemini API key is stored in plain text in chrome.storage.local — the same way Chrome stores all extension data. Chrome isolates this storage per-extension; other extensions cannot read it. If your machine is compromised, an attacker with local access could read it. We recommend using a Gemini API key with rate limits set on Google AI Studio so the cost cap is bounded even in the worst case.

Children

The extension is suitable for use by people of any age. It does not knowingly collect any data — there is nothing to collect.

Changes

If we change how the extension handles data, we'll update this page and bump the "Last updated" date. Since the extension is local-only, any such change would be visible in the source code of the same version on the Chrome Web Store.
