2 What personal data do we use
2.1Basic account data
We use the mobile phone number you provided to register, and use your uploaded picture and personal nickname as your user profile information.
Your mobile phone number will be used as a credential to find users and a mark to distinguish the users source region. The mobile phone number will not be displayed in other peoples data. If you dont want to be searched by others through the mobile phone number, you can turn it off in the privacy settings.
Your profile picture will be displayed in the data. By default, it is only visible to your contacts. You can set the display permission of your profile picture in privacy.
Your nickname is always public, but we do not require you to use your real name.
2.2 Your email address
You can set an email address as a remedy for forgetting the two-step verification password. We will not disclose it, and as a reminder, only the first and last two characters of the mailbox will be prompted.
We will not send any marketing content to your email address.
2.3 Your information
2.3.1 End-to-end encrypted chat
End-to-end encrypted chat includes: one-to-one private chat, encrypted group chat, encrypted anonymous group chat.
The text you send in an encrypted chat will be encrypted using end-to-end technology. Only the participants in the chat have the decryption key. The server only stores the encrypted text for you, and we cannot decrypt your message.
Your files, pictures, videos, audios, and sounds will be encrypted locally and uploaded to the cloud server. The encrypted key will be encrypted again end-to-end as part of the message. For cloud storage, the encrypted file Readability will be lost, the file name will be processed into unreadable random characters, and there is no way to know the usage scenario of this file in chat.
We store your encrypted chat data. You need to use the key information of the device you have logged in to decrypt the encrypted chat data. You can get these encrypted messages from any device at any time. If all the logged-in devices have been lost, we will clean up the encrypted data that cannot be decrypted after obtaining your confirmation.
2.3.2 Super Group
A super group can hold up to 100,000 people, and it is not technically suitable for end-to-end encryption. You will get this prompt when you set up a group chat.
Our global communication with the server is based on TLS encryption, which prevents your chat data from being eavesdropped or tampered with by others.
The files you upload in the super group are still encrypted to ensure that the cloud server itself cannot access your files.
The server will index the chat data of the super large group so that you can use the complete message search function when the local message is incomplete, and it is only valid for chat participants.
2.4 Address book data
We will not obtain your system address book permissions, and will not obtain your system address book data.
2.5 Location data
When you share location data with others, in an encrypted chat, your sending location data will be encrypted end-to-end, and only the client devices of the chat participants can know your shared location.
2.6 Call & Conference
The call or meeting in the encrypted chat will also use end-to-end encryption, and will be transferred through our VoIP server, which makes the IP information not exposed to the other party during the communication process.
2.7 Your device information
In order to complete the message push function and device management function normally, we will collect your device name, platform, system version, last login time and other information. You can check the device information collected by us in Settings-Active Sessions.
2.8 Screen Recording
In the desktop version of Enigma, we provide screenshot and video recording tools to help you to send pictures or videos with others and to share your screen in meetings, screen recording permission is requested to implement this feature.
The images or videos you generate using screenshots or screen recording will only exist in your clipboard or stored in a user-selected file directory through a save operation. The screen shared in the meeting will also be transmitted to the meeting participants’ device after encryption, and the server will not store your data or be able to view your data.
