BlockNSFW – Porn Blocker

BlockNSFW is a powerful yet lightweight content blocker that keeps your phone safe, focused, and family-friendly. It automatically blocks pornographic and adult websites before they load — across every app and browser on your device, not just one. Turn it on once and you're protected everywhere.

Unlike a simple in-browser blocker, BlockNSFW runs a private, on-device VPN that filters DNS for your whole phone. Blocking happens locally — your browsing is never routed to us, logged, or sold. It's free, has no ads, and will always stay that way.

🔑 Key Features
• Device-Wide Adult Blocking – Blocks known pornographic domains and adult platforms before the page loads, in every app and browser. Regularly updated blocklists.
• SafeSearch Enforcement – Forces family-safe results on Google, Bing, YouTube & DuckDuckGo.
• Maximum Protection (optional) – Adds a network-level layer using Cloudflare for Families to catch adult sites your on-device list might miss.
• Encrypted DNS (DoH) – Optionally send lookups over HTTPS so your network can't see them. Choose your own resolver.
• App Blocking – Block distracting or bypass-prone apps — including browsers that try to slip past the filter.
• Uninstall Protection – Make removing the app a deliberate step, not an impulse.
• PIN & Turn-Off Delay – Lock your settings with a PIN, and a built-in cooling-off countdown means protection can never be switched off in a moment of weakness.
• Protection Schedules – Force protection on during set windows — like a bedtime lockdown you can't turn off until morning.
• Streaks & Milestones – Build a protected streak and grow an evolving guardian shield as you go.
• Supportive Community – Read and share anonymous recovery stories from others on the same journey.
• Whitelist & Activity Stats – Manage your own allowlist and review what's been blocked — all stored on-device.
• Widget & Quick Tile – Check your status and turn protection on from your home screen or Quick Settings.
• Backup & Restore – Save your lists and settings, or move them to another device.
• Guided Setup – A simple wizard gets you protected in seconds.

👥 Who Is It For?
• Parents who want a safer device for their family.
• Anyone breaking a porn habit who wants real accountability, not just a flimsy blocker.
• Students and professionals who want to stay focused and distraction-free.

🔒 Privacy-Friendly
Filtering happens entirely on your device through a local VPN — no accounts, no sign-ups, and your browsing isn't tracked or sold. (Some optional features, like remote blocklist updates, DNS filtering, and the community feed, make network requests to work — see the privacy policy for details.)

With BlockNSFW, you stay in control of what reaches your phone. Simple, effective, and built for privacy.

BlockNSFW uses the Android AccessibilityService API to block apps you choose, to prevent its own uninstall, and to read the address bar in supported browsers so blocked sites can be covered. It sees the app you are using and that address text, processes both on your device only to decide whether to block, and never stores, collects, or shares them. Optional — turn it off anytime in Android's Accessibility settings.

BlockNSFW runs a local VPN on your device to filter DNS. It is not a remote VPN service — there is no server of ours, and your traffic is not tunneled or routed anywhere. Only DNS lookups pass through it: blocked sites are stopped on your device, and allowed lookups are forwarded to Cloudflare for Families over an encrypted connection. Android requires the VPN permission for this, which is why it shows a connection-request dialog.

Recent changes:
• Wireless Android Auto should now connect with protection on. Android Auto skips the VPN automatically, and it can't open websites, so nothing slips through.
• Switching BlockNSFW's VPN off in Android's settings no longer turns protection off. It comes straight back on. To turn protection off, use the app.
• Fixed a crash that could happen when protection was starting or stopping.

No ads, no account, no tracking. Protection is free — forever.
