DeniedPixels is a Safari extension that finds nudity on web pages and covers it before you see it. Images, video, GIFs and even explicit words in page text, censored in real time as you browse. Everything runs on your iPhone. Nothing is uploaded and no browsing data is collected. CHOOSE EXACTLY WHAT GETS COVERED 28 detection zones, each with its own toggle. Cover only explicit areas, or include faces, hands, feet and more. Set preferred sensitivity. Silhouette Masking covers a whole person along their outline instead of rectangles. 18 CENSORING STYLES Pixelate, Blur, Black Bar, Color Fill, Sticker, Noise, Glitch, Oil Paint, Redacted, Word Wall and Color Invert, plus seven animated styles: Static Noise, Scan Line, Spotlight, Shrinking, Permission Denied, Loading Bar and Pixel Wall. Every style is adjustable, and you can give each body part its own style. VIDEO, DONE PROPERLY Frame-accurate censoring that keeps up with playback, with minimum flickering or missing frames. Covers embedded video, GIFs and animated images. A loading placeholder keeps content hidden until it has been checked, so nothing flashes while a page loads. TEXT CENSORING Blacks out explicit words in page text. A built-in wordlist, your own additions, exceptions for medical or educational reading, and an on-device deep scan that catches writing which avoids obvious vocabulary. It never touches what you type. MODES Only Once: an image is permanently blocked after its first encounter. Decay: content degrades further each time you see it, until it is gone. Challenge: a number-guessing barrier before temporary access. Reverse: censor everything except the detected areas. Beta TV: the whole page pixelated, with one small window on the body part you chose. Red / Green Light: videos switch between visible and covered at random intervals, within limits you set. STAY LOCKED Self Lock puts your settings behind a password, a timer, or both. Shared Access lets someone you trust manage your settings remotely, and you can revoke it at any time. SITE BLOCKING A built-in blocklist of over 42,000 sites known for sensitive content, plus your own blacklist and whitelist. Or filter only on known sites and leave the rest of the web alone. PRIVACY All detection runs on your device with an on-device AI model. No images, URLs or browsing data are ever sent anywhere. ONE LICENCE, PHONE AND DESKTOP A subscription bought here also unlocks the desktop extension, so one purchase covers your phone and your computer. GETTING STARTED 1. Open Settings → Safari → Extensions (on iOS 18 and later: Settings → Apps → Safari → Extensions) 2. Enable DeniedPixels 3. Allow it on the sites you want covered 4. Browse Requires iOS 17 or later.

PixelBlocker is an on-device AI filter for Safari that censors NSFW images and videos in real time, before they ever load fully on screen. Every detection runs locally on your iPhone. No data leaves your device. Ever. There is no server, no account, no tracking. WHAT IT DOES • Scans every image and video on every Safari page you open • Detects 17 distinct content categories with adjustable confidence • Renders the censor instantly with your choice of 15 visual styles • Censor entire media: any detection blurs the whole photo or video, not just the detected area • Reverse censor (always shown as blur): blur the whole screen and see through only the regions it detects, with optional borders • Videos the filter cannot read are fully covered instead of playing clear • Blocks navigation to NSFW domains entirely (configurable list) HOW YOU CONFIGURE IT • Pick which content categories to filter (Lower body, Chest, Buttocks, Anus, Faces, Midriff, Feet, Underarms, exposed or covered variants) • Choose how it looks: Pixelated, Blur, Solid, Color Fill, Color Invert, Noise, Word Wall, Glitch, TV Static, Shrinking, Loading Bar, Permission, Spotlight, Pixel Wall, Oil Paint • Set custom text overlays per target category • Adjust border style and padding per-bucket • Save your favourite configurations as named presets ADVANCED SAFETY FEATURES • Partner lock: a person you trust holds the key. Your filter settings lock the moment you turn it on, and switching it off needs a one-time code that goes to their email, never to yours. Their address is never stored, and a 7-day emergency reset covers you if they ever become unreachable. • Self-lock: password-protect Settings so you can't disable the filter on impulse • Challenge Mode: tap a censored region, answer a trivia question to reveal it briefly, science, computers, games, refreshes daily • Only-Once Mode: any image you've blocked stays blocked forever, even if the detector misses it next time • 24-hour reset countdown if you forget the password, no shortcut LANGUAGES PixelBlocker is available in 10 languages, including the filter category labels, not just the menus. SUBSCRIPTIONS PixelBlocker is free to download. Optional subscriptions unlock more features: • Basic Monthly: £2.99 / month • Basic Yearly: £24.99 / year • Premium Monthly: £4.99 / month • Premium Yearly: £39.99 / year Payment is charged to your Apple ID at confirmation of purchase.
