App Description
Thunderbird is a powerful, privacy-focused email app. Effortlessly manage multiple email accounts from one app, with a Unified Inbox option for maximum productivity. Built on open-source technology and supported by a dedicated team of developers alongside a global community of volunteers, Thunderbird never treats your private data as a product. Supported solely by financial contributions from our users, so you never have to see ads mixed in with your emails again.
What you can do
Ditch multiple apps and webmail. Use one app, with an optional Unified Inbox, to power through your day.
Enjoy a privacy-friendly email client that never collects or sells your personal data. We directly connect you to your email provider. That’s it!
Take your privacy to the next level by using OpenPGP email encryption (PGP/MIME) with the “OpenKeychain” app, to encrypt and decrypt your messages.
Choose to sync your email instantly, at set intervals, or on-demand. However you want to check your email, it’s up to you!
Find your important messages using both local and server-side search.

Frequently Asked Questions about Thunderbird: Free Your Inbox APK
This variant is built for devices that report `arm64-v8a, armeabi-v7a, x86, x86_64` as their primary ABI. If your device's CPU matches, this is the smallest, fastest version to install.
Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.
Android 21 (API level 34) or newer. Older devices will refuse the install.
Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.
All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
