DuckDuckGo, optional Duck.ai

The DuckDuckGo, optional Duck.ai APK is a browser and search app for people who want to limit tracking while using the web. DuckDuckGo Search is built in and does not track your searches, while Duck.ai offers optional private chats with third-party AI models.

The browser blocks many third-party trackers before they load, along with most video ads and cookie pop-ups. It can also push many sites to use HTTPS and make browser fingerprinting more difficult.

Optional features include Email Protection, which blocks many email trackers and provides @duck.com addresses, and App Tracking Protection, which blocks many hidden trackers in other apps using a local VPN connection. Encrypted bookmarks and passwords can be synced across devices, and the Fire Button clears tabs and browsing data.

Some additional features are part of a subscription, including a VPN for up to five devices, advanced AI models, personal information removal, and identity theft restoration. The browser also offers settings to automatically manage cookie preferences.

DuckDuckGo, optional Duck.ai XAPK file

The download is a single XAPK file containing the app's base APK and split APKs. Install this XAPK with an XAPK installer app, as Android's installer cannot open it; the included APK files are the developer's originals with verified signatures and are also available separately.

Fixes bugs and improves the app.
