About Site Blocker

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. Privacy Policy This extension does not collect, transmit, or share any personal or sensitive data. All blocked site lists, Parent Mode settings, and passwords are stored locally in Chrome’s extension storage on your device. No data is ever sent to external servers or third parties. Passwords are stored securely as salted hashes, never in plaintext. The extension works fully offline. If you uninstall the extension, all settings (including blocked sites and password) are automatically deleted from your browser. Disclaimer This extension is provided “as is” without warranty of any kind, express or implied. The developer makes no guarantees regarding the effectiveness of the site blocking features. This extension should not be relied upon as a sole means of parental control, content filtering, or online safety. Children and technically advanced users may find ways to bypass or uninstall the extension. For stronger protection, please use Chrome’s supervised accounts, Google Family Link, or device-level parental controls in addition to this tool. By installing or using this extension, you agree that the developer is not liable for any damages, data loss, or consequences arising from its use or inability to use.
