Download

Available on the App Store

This app (the "official fork") is being sold for $0.99 in the Apple App Store. Click here to download.


Note: The app is currently unavailable in France due to import regulations on encryption software. The app is unavailable and does not work in China and Iran due to these nations blocking access to the Tor network.[]

Copies of Onion Browser downloaded outside the App Store — via "jailbreak" app directories like Cydia — are built and released by third parties and are not supported by the developer. These copies may have modifications added by the packager, which may interfere with your privacy or security. For the best security in non-App Store circumstances, you should build your own copy of the app.

Both organizations are registered 501(c)(3) charities in the United States, with publicly-available financial reports:
