Yggdrasil is a decentralised application with no central point of registration or communication. You do not need to register an account to use Yggdrasil, nor do you need to supply any personal information to the developers.
Yggdrasil deploys end-to-end encryption for all traffic crossing the network. This ensures that your traffic will not be readable or modifiable by third parties. The integrity of this encryption is guaranteed only if you take suitable precautions to protect your private keys. Do not share them with anyone.
Your identity on the Yggdrasil Network is derived from your encryption and signing keypairs, which are stored locally on your device. Your public encryption key is used to derive your network IPv6 address, which will be used whenever you send or receive traffic across the Yggdrasil Network.
You can discard your network IPv6 address/network identity and assume a new one at any time by discarding your keypairs and generating a new configuration with fresh keys.
Yggdrasil supports node information configuration through the
NodeInfo configuration section. By default, the
NodeInfo may also contain information about the version of Yggdrasil being run, on which operating system and architecture. You can choose not to publish this information using the
NodeInfoPrivacy option in your configuration. Any other
NodeInfo is entirely optional. You are not obliged to share any information.
On iOS, this is shown under “Node Info” in the Settings page. Any information entered into this section is published to the network and may be stored by network crawlers or by any other network user. You should therefore not publish any sensitive information in your
When you establish a peering, your network IPv6 address and public key are made visible to any peers to which you are directly connected. If peering over the Internet or another network, the remote peer may also be able to see your real IP address. If you are concerned about the storage or collection of information from a public node, you should contact the operator of that node.
No other information is collected. The Yggdrasil application (and the accompanying VPN network extension) itself does not collect any information whatsoever.
