Site Blocker

About

A simple, privacy-first site blocker for Chrome. Block distracting sites, set temporary unblocks, or enable Parent Mode for password-protected control.
Features
Block Sites: Add any domain (like reddit.com or youtube.com) or block the current site with one click
Temporary Unblock: Allow access for 2, 5, 10, 15, or 30 minutes
Parent Mode: Prevent blocked sites from being removed, require the password for temporary unblocks, and disable Parent Mode only with the master password.
When Parent Mode is off, no password is required.
When Parent Mode is on, the master password is required

Privacy
Secure Passwords: Stored locally as salted hashes (never plaintext).
All data stays in your browser (using Chrome’s local storage).
 No external servers, no analytics, no tracking.
Works fully offline.
Uninstalling the extension clears all settings, including blocked sites and passwords.
	 
How To Use
Click the lock icon in your Chrome toolbar.
Add sites to the block list.
(Optional) Set a master password and turn on Parent Mode.
Manage blocked sites and temporary unblocks right from the popup.
NOTE: If you forget your password, you will need to uninstall and re-install. In order to preserve data privacy I opted to not need a formal account to use this extension. You can change your password at any time without knowing your current if "parent mode" is disabled. To ensure kids don't uninstall the extension to bypass the controls, it's suggested to use a monitored google account.
