Keep your data secure

A snapshot from holiday, quickly sent via the messenger service – a nice greeting directly on the smartphone instead of a postcard. But does the image really reach only the recipient? Yes! G DATA SECURE CHAT makes sure of it. With its reliable encryption, nobody but you can access your data.

Send SMS securely

A security key that you share with other users guarantees that only they can read your messages.

Encrypt chats with your group

Your data is also encrypted when sent in a group chat. The keys are on your contacts' smartphones.

Self-Destructing Messages

With the self-destruct timer, you can rest assured that your personal data will not be forwarded to third parties.

Encrypted data sharing

Middlemen are left with no chance: Only your smartphone and the recipient's device can decrypt the messages that are sent. Your data traffic remains secure and you retain all rights to the contents.

Complete protection with no holes

G DATA SECURE CHAT is open source software, meaning that the source text is freely available and has been checked in detail for backdoors and security holes. Independent organizations have found the app to be secure.
