Create your lock

When you open Tella for the first time, you’ll be asked to choose how you will lock Tella. Without this lock, it is not possible to open Tella and access any of the files stored in Tella.

  • Password: an alphanumeric password is the most secure way to lock your App.
  • PIN: a numeric sequence of more than six (6) digits.

Avoid using your name, date of birth, or anything that is easy to guess (like “Password”, “123456”, or “000000”).

Keep in mind that if you forget this lock, there is no way to access the app or its content.

Grant permissions to Tella

The first time you use each functionality, you will be asked to grant Tella some permissions:

  • To take photos, record videos, or record audio, you will need to grant permission to access your phone’s camera and microphone.

If you do not grant Tella these permissions, you can do it later by going to your iPhone settings and navigating to Settings > Tella > Allow Tella to access to Camera, microphone and files.

Protect your files

After granting permissions, you’re ready to start collecting documentation. We recommend you to explore the following features:

Use the Camera to take pictures or videos and the Audio Recorder to record audio. All media taken by Tella will be encrypted instantly, which means that the file will not be accessible outside of Tella. All media collected inside Tella will not show on your phone gallery or phone files. There is no particular storage limit for Tella, the available space will depend on the space available on your device.

Import your files to Tella. Go to any of the folders inside Tella and tap the + Button > Import from device. Choose the file you’d like to keep inside Tella and a copy of the file will be stored encrypted and hidden on Tella. You will be asked to chose if you want to delete or keep the original file from your device. Tella will be unlocked while you choose your files for a maximum of three (3) minutes.

Rename files: Another way to keep your data organized is to rename files to be more descriptive. By default files receive an auto-generated name. You can change it by clicking on the three (3) dots that are next to each filename and then tap Rename.

Share your information

To share information using Tella you can use the Share button. Just select the file or files you want to share, press Share and choose the app you want to share the files with.

Take into account that Tella will share the files unencrypted, so make sure to use disappearing messages (for example on WhatsApp or Signal) or delete the messages after the other person receives them.
