Private Browser

Private Browser is a fast, ad-free way to use the web on iPhone. It blocks ads and trackers before they load, keeps your browsing to yourself, and puts a lock on the whole app. No account. No profile. Nothing sold. BLOCK ADS AND TRACKERS • Over 135,000 filter rules from EasyList and EasyPrivacy, applied before a page starts loading • Pages load faster and use less data, because the ads never arrive • Cookie banners hidden automatically • A live counter shows exactly what was blocked on the page you are reading • Turn protection off for one site you trust, without turning it off everywhere PRIVATE TABS THAT REALLY ARE PRIVATE • Private tabs use a separate, temporary store — nothing is written to disk • Close the last private tab and the whole session is destroyed, not just hidden • Normal tabs keep history only for as long as you want it; clear any part of it in one tap LOCK THE APP, NOT JUST THE SCREEN • Face ID, Touch ID or a passcode to open the app • The page is covered the moment you switch apps, so nothing shows in the app switcher • Files you download are stored with iOS file protection and stay unreadable while the device is locked BUILT FOR READING, NOT FOR ADS • Reader mode strips a page down to the article • Dark mode for any website, not just the ones that support it • Toolbars get out of the way as you scroll and come straight back • Tabs, bookmarks, reading list and downloads, all where you expect them SEARCH THE WAY YOU PREFER • Choose from DuckDuckGo, Google, Bing, Brave, Startpage, Ecosia, Yahoo or Baidu • HTTPS-Only mode, so an insecure page never loads by accident • Encrypted DNS guidance built in • QR scanner, downloads manager and full backup SPEAKS YOUR LANGUAGE Every screen is translated into 36 languages, including Arabic and Hebrew with full right-to-left layout. PRIVATE BROWSER PRO Private Browser Pro removes every upgrade prompt, includes each new feature as it arrives, and comes with priority email support. Choose a weekly or yearly subscription, or buy Lifetime once and own it outright with no subscription at all. The price for your country, the renewal date, and the length of any free trial offered are always shown in the app before you confirm. Nothing is charged until you do, and a free trial is free. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours of the end of that period. You can manage or cancel a subscription at any time in Settings on your device.
