Description

From the listing uploaded by “appupdater”.

Tella . In challenging environments--with limited or no internet connectivity or in the face of repression--Tella makes it easier and safer to document events, whether that’s violence, human rights violations, corruption, or electoral fraud. ENCRYPTION: All of the content and data stored in Tella are encrypted. This means that unless the app is unlocked, all the data within Tella will remain inaccessible. FILE MANAGEMENT: Take photos, videos, or audio recordings directly in Tella, or import documents from your phone, and easily organize your files in folders. CAMOUFLAGE: Change the app icon and name to a seemingly harmless one, such as a calculator or a camera. QUICK DELETE: In just a few seconds, delete all the sensitive data and files stored in Tella. DATA-COLLECTION: Groups and organizations can collect data through forms and surveys, and received the data directly on their server.
