# About Thunderbird for Android

Thunderbird for Android (TfA) is a powerful, privacy‑focused email app for managing multiple accounts with ease —
including a Unified Inbox for maximum productivity. It’s open source, built with the community, and never treats your
private data as a product.

## �� K‑9 Mail heritage

Thunderbird for Android is based on **K‑9 Mail**, a long‑standing open source email app. The projects share much of
the same code and therefore may look and feel similar.

Some features are selectively enabled in Thunderbird when they are a better fit for Thunderbird users (e.g., import from K‑9).

If you prefer to keep using K‑9 Mail, you can find it here:
- [Google Play](https://play.google.com/store/apps/details?id=com.fsck.k9)
- [F‑Droid](https://f-droid.org/packages/com.fsck.k9/)
