Disclaimer

Using Onion Browser does not guarantee security or privacy on its own. It simply provides a set of features that may enhance privacy and anonymity while browsing the web. Please remember the following...

Apple requires all web browser apps to use the same core web rendering ending, called UIWebKit or WKWebView. Due to this limitation, we are unable to compile and include our own web engine, based on Firefox Gecko, that other browsers, like Tor Browser on Desktop and Android, are allowed to do.

Onion Browser only tunnels traffic within the Onion Browser app. Please note that network traffic outside of Onion Browser is not protected and will continue to use your normal connection.

If you use Onion Browser to log into websites that you normally access outside of the Tor network, the website may be able to identify you and know that you are using Tor. In certain circumstances (e.g. political dissent in repressive nations), this may be incriminating information in itself.

Limitations in iOS

iOS has full control over some network traffic, which may result in this traffic (including audio or video embeds) routing via your normal connection and not over Tor.

Geolocation and Advanced HTML5 Features

Websites may use the HTML5 Geolocation API (to view your current GPS location) and other new HTML5 features unless "Strict" security mode is set. Users should also remain vigilant for any pop-ups asking for permission to access location data.

More Information

The Tor Project maintains a small page of tips about staying anonymous while using Tor.

A log of Onion Browser release notes, including previous security issues and results of previous security audits is available here. You can also see the Github project for a current list of known issues.

Free and open.
