The messenger uses several factors, which combined, result in a highly secure service. Here are the most important ones for you summed up:

• Data minimization. We respect and therefore, protect your privacy as you do not need to indicate a telephone number, your email address or any other sensitive data to our messaging service.
• Transport and end-to-end encryption are protecting your messages
• Servers: Our servers are all located in Germany and are therefore subject to the German data protection law. All messages and attachments are encrypted and only stored on our servers as long as they are in transmission. Afterwards they are deleted immediately.

No! The app accesses your address book and your location data only to create encrypted attachment data and no information from your address book or location data is transferred to our servers in a form we can decipher.

Not yet, but we are working on it.

Yes! Here’s how it works:

for iOS

Export account data

1. First, open iTunes on your computer.
2. Open our messaging app on your device and tap on your profile and “edit”.
3. Scroll down and press “export credentials”. You will be asked to pick a strong password.
4. Then connect the device to iTunes and go to the device page.
5. Then select the Apps tab and scroll down to the file sharing section and select our messaging application. In the right hand list you will find the file credentials.json.
6. Drag and drop it to the desktop.
7. Now your log-in data is saved on your computer.

Import account data

1. To transfer your account information to a new/other device, you need to connect that new device to iTunes.
2. Select the device and go to the Apps tab again.
3. Select our messaging service in the file sharing section and drag credentials.json from the desktop to the right hand list.
4. Now launch the messenger on your new device and go to your profile.
5. Tab edit and press “import credentials” and enter the password you have chosen at the beginning of this process.
6. Relaunch the app and enjoy.

for Android

Export account data

1. Open our messenger on your device and tap on settings and „export credentials“.
2. You will be asked to pick a strong password and tab „OK“.
3. Then connect the device to your computer or use a file manager app.
4. You will find a file named „credentials.json“ in the root directory of your device.
5. Copy that file to your computer or to another device.
6. Now your log-in data is saved.

Import account data

1. To import your credentials to an other/new device, transfer those credentials to your new phone and make sure that it is located in the root directory.
2. Start the app again and go to “settings” and tap “import credentials”.
3. Enter now the password you have memorized beforehand and tap “OK”.
4. Now the credentials will be loaded from the imported file and all your contacts will be synchronized.
5. To be sure, please restart the app and enjoy!

Please note: You cannot run one account on multiple devices yet!

We store messages as long as they are in transmission. Once a message reached the designated recipient, it is deleted immediately.

• Access control / Passcode request
• Touch-ID control (iOS user only)
• Mugshot (iOS user only)

Access Control

Protect your app and all its contents with our access control feature:

• App settings > Access Control > Passcode timeout

Set the passcode timeout and enter a passcode. This passcode is now requested when opening the app.

Please note: Memorize your passcode well as it cannot be recovered. iOS users can also activate touch-id for access control (iPhone 5s, iPad air, iPad mini 3 or newer).

Mugshot (iOS only)

Besides the passcode protection, you are now able to activate the mugshot feature:

• App settings > Access Control > Enable Mugshot

When entering a wrong passcode a photo will be taken with the front camera. This photo is saved in your app under Media > Visual

(The mugshot is intently not saved to your phone’s library as an unauthorized user would have access and be able to delete it.)

When this feature is activate and no passcode is set, a mugshot is taken every time you open the app.

Our service is optimized for all Android versions starting at 4.0. „Rooted devices“ are not included. Please note, that our messenger could crash due to lacking permissions on rooted devices. Performance issues can also occur.

To keep our service running, we need to store some user information on our servers:

• a persistent random number representing your client id
• the chosen nicknames
• the chosen avatars
• relationship to other clients and group memberships

To delete these information for good, you need to delete it from our server. As a result, you will not appear in your friends’s contact list, will be deleted from your active groups and you won’t be able to login anymore. Deinstalling the application does not do the trick. So here is how it works:

Delete account from server

1. Open your profile
2. Edit profile
3. Select “delete account from server” and confirm

Please note: Once you have deleted this information from our server, the account is deleted for good. No backup or credential import will restore this information. The server will refuse any login from an unknown user and that’s what you are once the account is deleted.

We have no insight to contents that are sent with our app. We regard ourselves as a data transport service and offer users the freedom to transfer all non DRM-protected files safe and fast and without any restrictions of form or size. Needless to say, users have to note third-party rights to the shared files.
