Upcoming changes and guidance to back-up files

The next release of Tella Android will include an update to the library used to save encrypted information encrypted in the database (SQLcipher). While we are doing our best to ensure the update to the new version happens smoothly, there is a small risk that some files are lost in the process. For users who are storing sensitive files in Tella, we strongly suggest to back-up these files to a location outside of Tella. This way, if something happens when updating Tella, those files will not be lost.

To export files outside of Tella and save them on your phone:

1. Go to All files (or any folder where there are files you want to backup)
2. Tap on ☑️ in the top right of the screen to enable "select mode"
3. Tap on ☐ in the top right to select all files, or tap ☐ next to each specific file you wish to export
4. Tap on ⫶ in the top right to open the context menu
5. Tap on Save to device
6. Select the destination folder to save your files. You can read more about sharing data from Tella through other apps here.

If you prefer sharing your files through another app:

1. Go to All files (or any folder where there are files you want to backup)
2. Tap on ☑️ in the top right of the screen to enable "select mode"
3. Tap on ☐ in the top right to select all files, or tap ☐ next to each specific file you wish to export
4. Tap on ⫶ in the top right to open the context menu
5. Tap on Share
6. Select the app you want to use to share your files. We recommend using an encrypted email, Signal or any other tool with robust privacy. You can read more about sharing data from Tella through other apps here.
