TWINME PRIVACY POLICY

Last update on November 22nd, 2016.

twinme provides end-to-end encrypted peer-to-peer calling and messaging.

Twinlife as the operator of twinme servers has no way to decrypt messages or calls between twinme users because (1) exchanges happen in peer-to-peer directly between devices, with no staging server storing content, and (2) Twinlife does not have knowledge of the private keys used to encrypt data.

INFORMATION TWINLIFE HAS

1. Information stored by twinme servers

  • The unique identifier randomly generated when twinme was activated on your mobile device for the first time, which is used as an account identifier.
  • Profiles’ information (e.g., avatars and nicknames) you and your twinme contacts use to refer to one another.
  • Randomly generated tokens (i.e., twincodes), used for setting up a call or transmitting a message between a particular pair of contacts.

2. Transient information

  • Certain information (e.g., twincodes and their IP address at this particular time) is transmitted to twinme signaling servers solely for the purpose of placing calls or transmitting messages. Unless otherwise stated below, such information is only kept as long as necessary to place each call or transmit each message, and is not used for any other purpose.
  • Log information used for statistical purposes on the general use of the twinme service during given periods of times (e.g., number of users, device brands and operating systems, locations, number and duration of calls, number of messages exchanged, etc.).

3. Information accessed on your device

  • twinme does not access any personal information from your device such as your phone number or address book.
  • twinme asks your permission to access
    • your camera to be able to take photos used as avatars in your profiles;
    • your photo album if you want to use pictures as avatars in your profiles, or send them as messages to your contacts;
    • to your secondary memory (SD-Card) if you have one, to access its contents you want to use or exchange with twinme;
    • your camera and microphone to make voice or video calls;
    • your networks and systems tools to communicate and notify you of incoming calls and messages.
  • None of the information accessed by twinme on your device is sent to the twinme servers except as mentioned in the previous two sections.

4. Information stored on your device

  • Profiles’ information (e.g., avatars and nicknames) you and your twinme contacts use to refer to one another.
  • Contents of messages exchanged in conversations with your contacts, until the conversation has been reset. Once reset, all messages sent and received in a conversation are erased on both devices: yours and your contact’s device.

  • With your consent.
