About SiteLocker

Overview SiteLocker is the ultimate website blocker and productivity extension for Google Chrome. Block distracting websites, overcome procrastination, reduce screen time, and protect your privacy by locking sensitive domains behind a secure 4-digit PIN. Are you tired of endless doomscrolling on social media? Do you struggle to stay focused while studying or working from home? SiteLocker is a premium site blocker designed to help you take back control of your digital wellbeing. By restricting access to time-wasting sites, SiteLocker acts as your personal focus assistant, ensuring you stay on track without having to rely on willpower alone. Whether you are looking for an ADHD productivity tool, a study aid for exams, a Pomodoro focus timer, or a simple way to secure specific URLs from prying eyes, SiteLocker provides an intuitive, privacy-first solution directly inside your browser. CORE FEATURES 🚫 Advanced Website Blocker & URL Filter Instantly block access to any distracting or sensitive website. Create a custom blocklist of domains you want to restrict. Whether it's social media, news outlets, video streaming platforms, or online shopping, SiteLocker stops you from accessing blocked sites when you need to focus. 🔒 Secure 4-Digit PIN Protection Unlike basic site blockers that can be easily turned off, SiteLocker protects your blocklist and extension settings with a secure 4-digit PIN. This friction prevents you from easily bypassing your own restrictions in moments of weakness, making it highly effective for breaking bad habits. ⏱️ Focus Mode & Productivity Timer Start a timed focus session to lock in and get work done. Inspired by the Pomodoro technique, Focus Mode strictly enforces your blocklist for a set amount of time. During an active focus session, selected websites remain locked, forcing you to concentrate on deep work. 🎨 Beautiful Custom Themes Personalize your digital workspace with 6 built-in visual themes. Choose between dark mode, light mode, and colorful aesthetics to match your browser's vibe and enhance your user experience. 🔑 Seed Phrase Recovery System Never worry about getting locked out forever. SiteLocker is the only website blocker that provides a secure, crypto-style seed phrase recovery option. Keep your recovery phrase safe to regain access to your blocklist if you ever forget your PIN. 🛡️ 100% Local-First Privacy (No Account Required) Your data belongs to you. SiteLocker operates completely offline with a local-first privacy approach. All custom blocklists, configurations, and PIN data are stored locally on your device. We do not require you to create an account, and we never track, store, or sell your browsing history. 💡 WHO CAN BENEFIT FROM SITELOCKER? 🎓 Students & Academics: The perfect study app. Block YouTube, Reddit, and social media while studying for exams, writing essays, or doing research. 💼 Remote Workers & Freelancers: Stop multitasking and eliminate digital distractions. Use Focus Mode to dedicate uninterrupted blocks of time to your most important projects. 🧠 Neurodivergent & ADHD Users: A highly recommended accessibility tool for managing screen time, combating hyperfocus on the wrong tasks, and building healthier digital habits. 🛡️ Privacy-Conscious Individuals: Secure sensitive browser configurations and lock specific URLs without signing up for yet another cloud-based account. 🛠️ HOW IT WORKS (In 3 Easy Steps) Install & Set PIN: Add SiteLocker to Chrome and immediately set your secure 4-digit master PIN. Add Distractions to Blocklist: Type in the URLs of the websites that drain your time (e.g., facebook.com, twitter.com) and add them to your locked list. Start Focusing: Browse the web normally. If you try to visit a locked site, SiteLocker will intercept the page and prompt you for your PIN, giving you the moment of pause you need to get back to work. ❓ FREQUENTLY ASKED QUESTIONS (FAQ) How do I block websites on Google Chrome? Simply install the SiteLocker extension, open the dashboard, and type the URL of the website you want to block. It will be instantly restricted. Can I use this as a Pomodoro timer? Yes! Our Focus Mode acts as a built-in productivity timer. Set the timer for 25, 45, or 60 minutes, and your blocked sites will remain inaccessible until the timer runs out. Is SiteLocker safe to use? Absolutely. SiteLocker requires no account, no cloud syncing, and runs locally on your machine. Your browsing data never leaves your computer. What happens if I forget my PIN? During setup, SiteLocker generates a unique seed phrase for you. You can use this phrase to reset your PIN and recover your settings at any time.
