“This app is no longer shared with you” – What can I do?
Go to iOS Settings > General > iPhone Storage > Threema and choose “Offload App”. When this has completed, start Threema again. The system should automatically reinstall Threema without losing any data.
If you have accidentally answered “No” when asked whether you want to allow Threema to access your photos, you can grant permission as here:
- iOS Settings > Privacy > Photos > Threema
If Threema is not listed in the location mentioned above, please remove restrictions for Threema:
iOS 12: iOS Settings > Screen Time > Restrictions > Photos > Allow Changes
iOS 11 and earlier: iOS Settings > General > Restrictions > Photos > Allow Changes
There are two ways to share files using Threema on iOS.
Select the files in Threema: In a conversation, tap the plus sign (“+”) next to the input box, and select “Share File”. Then, choose the app that hosts the file you would like to share (e.g. Contacts), select the file, and confirm by tapping “OK”.
Select the files in another app: In the app of your choice, select the file you would like to share, tap the Share Button, choose “Open in Threema” (depending on the app, you might need to tap “Open in…” first), select the contact you would like to send the file to, and confirm by tapping “Send”.
The latest version of Threema runs on iOS 15 and up. You can continue to use older Threema versions on your pre-iOS 15 device, but you won’t be able to update to newer versions.
Older Threema versions don’t support all the features newer versions provide, and it’s advisable to install the lastest Threema version whenever possible.
Here are the last supported Threema versions for each iOS version:
- iOS 9: Threema 4.2.3
- iOS 10: Threema 4.6.18
- iOS 15: Threema 4.8
The effort needed to offer compatibility with older iOS versions is substantial. For this reason, we need to drop support for older iOS versions from time to time when we release larger updates.
Adjust the notification settings of a single or group chat in the iOS app as follows:
- Open the desired chat, and tap the title bar. Then, tap the bell symbol in the bar that appears below the title bar to open the notification settings. With version 4.8 and above, the notification settings can also be found in the detail view of a contact or a group.
Activate “Do Not Disturb” to disable notifications (for a certain duration). In group chats, the option “Notify When Mentioned” is available. If activated, you will only receive notifications for messages in which you are
- To mute notifications, deactivate “Play Notification Sound” in the detail view under “Notifications.” You will still receive notifications, but no notification sound is played.
In and of itself, Threema does not provide an option to save chats on iCloud. If, however, you have chosen to save device backups on iCloud, all app data, including Threema chats, will be stored on iCloud.
Neither is there a way for third-party apps like Threema to control this behavior, nor can such apps detect whether iCloud device backups are enabled or not. Even though apps can exclude individual files from backups, these files are excluded from all backups, also from encrypted iTunes backups. Therefore, we recommend to either create iTunes backups instead of iCloud backups or to exclude Threema if you must create iCloud backups.
Threema Work admins can use the MDM parameter th_disable_system_backups to prevent iCloud and iTunes from including Threema Work data in backups. As mentioned above, it is, however, not possible to only allow iTunes backups.
To learn more about security aspects of iCloud backups, please refer to this Apple article.
Thank you for your interest in testing the beta version of Threema. In order to participate in the beta program, it’s required that you have purchased the regular app version in the App Store.
For users who want to test the tech preview of Threema 2.0 for desktop, there’s an additional beta testing program. It’s possible to participate in both programs at the same time. Any releases of the multi-device beta of Threema 2.0 will take precedence.
Please note: The beta version can contain bugs, and data loss might occur. Be sure to create a backup before installing the beta version!
