LeetReminder Privacy Policy

Last updated: September 20, 2026

LeetReminder is a Chrome extension that schedules spaced-repetition reminders for LeetCode and NeetCode problems. It does not collect, transmit, or sell any personal information.

The extension is open source, so everything described below can be verified in the code at github.com/geldrezNicholas/LeetReminder.

What the extension stores

When you add a problem, the extension saves the following on your own device:

• The problem's URL slug, title, and difficulty
• Which site or sites you added it from
• The date you added it, its review dates, and which reviews you have completed

This is held in chrome.storage.local, which is local browser storage on the machine you installed the extension on. It is not synced to a Google account and it is not copied anywhere else.

What is not collected

• No names, email addresses, or account information
• No browsing history, and no record of pages you visit
• No analytics, telemetry, crash reporting, or usage tracking
• No cookies or advertising identifiers
• No code or solutions you write

Where the data goes

Nowhere. The extension has no backend, makes no network requests, and contains no third-party libraries or services. Nothing you save leaves your browser, so there is no data for anyone to share or sell.

Why it asks for the permissions it does

• Storage holds your problem list on your device.
• Alarms wakes the extension periodically to work out what is due.
• Notifications shows the daily reminder.
• Active tab reads the current tab's address when you click Add, so it knows which problem you mean.
• Scripting, together with access to leetcode.com and neetcode.io, reads the problem title and difficulty from the page you are adding so the entry is labelled correctly. These two sites are the only ones the extension can access.

Keeping or deleting your data

Delete individual problems from the extension at any time. Uninstalling the extension removes everything it stored, permanently. Because nothing is kept on a server, there is no backup and no way to recover a deleted list.

Changes

If this policy changes, the updated version will be posted on this page with a new date.

Questions about this policy can be raised as an issue on the extension's source repository at github.com/geldrezNicholas/LeetReminder, or through the Support tab on its Chrome Web Store listing.
