Which version of Android is required?

Starting with version 4.6, the Threema app for Android requires Android 5.0 or later.

For security and compatibility reasons, Threema apps must run on current operating system versions. It is therefore inevitable that support for outdated operating systems will be discontinued from time to time.

Android 4.4 users can continue using Threema 4.59 for now if the app is already installed. However, please note that Threema 4.59 is no longer available for download.

Can I buy/use Threema without a Google account?

Yes, if you buy the app fromthreema storeor throughF-droideapp store, you don't need a google account.

Thanks toThrust Threema, you can also use Threema without Google services.

If you use a Huawei device that is not equipped with Google Services, you candownload Threema from Huawei's AppGallery.

Why is sync no longer working after restarting my phone?

This issue only affects the Android version of Threema on specific Android OS versions.

Some versions of Android (Jelly Bean 4.1.1 is often affected, and on some Samsung devices even newer versions) have a bug that affects paid apps. Sync account is lost after phone reset; consequently, contact synchronization no longer works. We are currently looking for a reasonable solution and recommend all users to upgrade to a newer OS version if possible.

As a workaround, you can disable and re-enable synchronization in Threema settings. This will cause the account to be recreated and the sync working again until the next phone restart.

More information about this Android error can be foundhere.

How can I reinstall the app without data loss?

You may experience issues with Threema after updating your phone's operating system or making other changes to your phone. In this case, it may be necessary to reinstall the application. To avoid losing your data, follow the steps below:

  1. Create a data backup in Threema that includes media files (find outwhich).
  2. Go to Android > Settings > Applications > Threema.
  3. Tap "Clear Data" and uninstall the app.
  4. Restart your phone and reinstall the app.
  5. Open Threema and restore the previously created backup with our setup wizard.

Why can't I update the app from the Google Play Store?

Bought Threema from the Google Play Store but can't see updates or an install button on the Google Play Store? Proceed as follows:

  1. Make sure you're using the same Google account you had when you purchased Threema.
  2. On your computer, log in toplay.google.com🇧🇷 Go to "Profile Icon (circle with initials) > Payments & Subscriptions > Budget & Order History". Is Threema on this list?
  3. If Threema is listed, please delete data from Google Play Store and Download Manager apps on your phone according tothese instructions.
  4. Restart your phone and sign in to the Google Play Store. Now you can proceed with updating or reinstalling Threema.
  5. If Threema doesn't appear in "Order & Quote History", you were using a different Google account when you purchased Threema, or you purchased fromour own store.

Why am I always asked for the master key password?

Android automatically closes background tasks if you're running low on memory. This can affect a process responsible for keeping the password present in memory. You must re-enter your password when starting Threema. Threema can't change that.

If you are frequently asked for your password, we recommend disabling it and using global encryption on your device. You can find this in your phone settings: Security > Encrypt Phone or Security > Encrypt Device.

What does the message "The master key is unlocked" mean?

This notification is displayed if you are using the Android version of Threema and have set a passphrase in your master key. To prevent the operating system from terminating the Threema process (resulting in the loss of the unlocked master key as it is only stored in RAM, requiring manual re-entering of the password), the application must display a notification. This notification serves no other purpose and is only necessary due to the aforementioned Android limitation.

Note: In times of extreme memory shortage, Android will terminate even processes that display a persistent notification. In this case, you may be asked to enter the master key password again. This is caused by Android; Threema has no influence on the termination of this process.

How can I save files (media)?

Save individual files (media) manually

First, tap and hold the desired (media) file in the chat. Then open the menu via the three vertical dots and tap "Save".

Starting with Android 10 and Threema 4.5 for AndroidFiles (media) are saved in the following directories depending on the file type:

  • Images/Threma
  • Movies/Threma
  • Music/Threma
  • Documents/Threma

No Android 9 e anterior, media files are saved in the “Threema/Threema Pictures” (or “Threema Videos”/“Threema Audio” directory, depending on the file type). Files are stored in the global "Downloads" directory on your device and are accessible through the Downloads app.

Automatically save received media files

In Threema, go to "Settings > Media & Storage" and enable "Auto Save to Gallery". Autosaved media files are located in the same directories as manually saved media files, see above.

What are distribution lists?

On Android, distribution lists can be used to send messages to multiple recipients. Unlike group chats, messages are sent to recipients separately when using distribution lists. Therefore, recipients are unaware that other recipients received the same message. Sending a message to a distribution list is basically the same as sending the message to each member of the distribution list in a single chat.

To create a distribution list on Android, proceed as follows:

  1. On Threema's main screen, open the menu (by tapping the three vertical dots in the upper right corner) and select "New distribution list"
  2. Select the recipients who will receive messages sent to this distribution list and finalize your selection by tapping the check mark in the top right corner
  3. Specify a name for the distribution list and confirm by tapping "OK"

If you want to send the same message to several recipients without creating a distribution list, proceed as follows:

  1. Tap "Start Chat" in the chat overview
  2. To select recipients, tap and hold the contacts you want to send the message to
  3. Tap the right arrow
  4. Compose and send the message. It will be sent to each recipient separately.
  5. To return to the chat overview, tap the arrow in the top left corner. As soon as you return to the chat overview, the mailing list you just used will no longer be available.

What is notification priority?

Notification priority can be adjusted in Threema > Settings > Sound & Notification > Priority. This setting controls how notifications are prominently displayed. The default is High and should not be changed. Adjustments to this setting can have different effects on different devices and on different versions of Android. In general, the Low setting should prevent pop-up notifications from appearing.

What are notification channels?

As of Android 8.0, apps must assign their notifications to so-called "notification channels". These channels determine which signals (notification sound, light, vibration, etc.) trigger incoming notifications.

For privacy reasons, Threema does not create a separate notification channel for each contact, but one for each combination of notification settings. A channel's ID is a hash of its notification settings.

Edit notification settings

Only edit notification settings for chats and calls in Threema (in Settings > Sound & Notifications or individual chat notification settings), not in System Preferences. Changes made to System Preferences will be lost.

Xiaomi: Why is there no popup or sound when new messages arrive?

  • On Threema, go to Settings > Sound & Notifications
  • Tap on “MIUI Settings”
  • Enable all (or desired) notification settings for Threema:
    • show notifications
    • Show app icon badges
    • floating notifications
    • lock screen notifications
    • allow sound
    • allow vibration
    • Allow using LED light


If an application like Threema creates anotification channelIn MIUI 10, only vibration can be enabled as a notification signal, all other signals (warning, sound, notification light, etc.) are disabled by default and need to be enabled manually.

Enable notification signals as follows:

  • On Threema, go to Settings > Sound & Notifications
  • Select "MIUI Settings"
  • Open the first entry in the Chats section
  • Enable all settings (floating notifications, lock screen notifications, sound, etc.)
  • Return to the previous screen and repeat the procedure for all other entries in the Chats section

When a new notification channel is added (ie when you start using a new combination of notification settings), you will also need to enable that channel's notification settings as described above.

Due to Xiaomi restrictions, Threema cannot automatically adjust notification channel settings for you. For some selected apps, Xiaomi has enabled all notification signals by default. Please contact Xiaomi for more information.
