Incognito is a private web browser you can pull up anywhere. From any app: long-press a link or select text, tap Share, and then choose the Incognito action extension. Boom: instant web browser! Need to lock people out of your web history or bookmarks? Incognito can do that too! Incognito is great for: • Viewing a web page inside the current app without jumping to Safari. • Opening sketchy links without risking your privacy. • Reopening a web page with cookies disabled — and yes, that means Incognito lets you dodge most paywalls. • Searching Google from anywhere — just select the text you want to search, choose “Share” from the popup menu, and then choose the “Search in Incognito” action. • Searching with something besides Google: use Kagi, DuckDuckGo, Bing, Brave, Qwant, Yahoo, or whatever search engine you prefer. • Keeping your web history and bookmarks private and passcode-locked. Or you can disable browsing history and leave no trace! Incognito is also a Swiss Army Knife of web tools: • Open a page in another browser such as Safari, Chrome, Firefox, Opera, Brave, or DuckDuckGo. • Remove AMP so you can browse or share the original URL. • Translate the page using Google Translate (beta). • Open a web page with the archive.today service (Incognito is not affiliated with archive.today or archive.is). • Save a PDF of an entire web page. • Set Incognito as your default browser. • Clear your session history. Incognito is all about privacy: • All web browsing is in “private mode” by default, so all cookies and web data are discarded after each session. • Incognito has no ads, no third-party trackers, and does not send or re-route your web searches anywhere. • If you require extra privacy, Incognito has options to disable browsing history and/or exclude it from your iCloud Backups. Incognito is paid upfront with a small, one-time fee. There are no subscriptions, in-app purchases, ads, or deals with sketchy "search engines" like many of the "free" so-called private browser apps. You can trust me with your privacy because you know how I got paid: once, by you, that's it. Incognito was created by an independent developer living in California.
