Sigwo Technologies, LLC and Metis Messenger Terms & Privacy Policy

Metis Messenger utilizes state-of-the-art security and end-to-end encryption to provide private, decentralized messaging (“Services”). Your photos, files, and messages are always encrypted, so they can never be shared or viewed by anyone but yourself and the intended recipients.

Information you provide

Account Information. You provide nothing to create a Metis Messenger account. You may optionally add other information to your account, such as a profile picture. This information is stored on Jupiter’s blockchain. Your Metis Messenger account’s alias and profile picture are publicly available on the Jupiter blockchain.

Messages. Metis Messenger cannot decrypt or otherwise access the content of your messages or calls. Metis Messenger does not store messages on Metis instances for delivery to devices that are temporarily offline (e.g. a phone whose battery has died). Your encrypted messages are stored on the Jupiter blockchain for retrieval when your phone requests them.Additional technical information is stored on our servers, including randomly generated authentication tokens, keys, push tokens, and other material that is necessary to transmit messages. Metis Messenger limits this additional technical information to the minimum required to operate the Services. If you desire, you can service your own Metis server for more ownership. All Metis server instances on Jupiter’s mainnet will interoperate. For example, a locally installed Metis server on a MacBook Pro will pass messages to the publicly used Metis instance maintained by the Jupiter Project.

Contacts. Metis Messenger does not ask for access to your contacts.

User Support. If you contact Metis Messenger User Support, any personal data you may share with us is kept only for the purposes of researching the issue and contacting you about your case.

Managing your information. Metis Messenger’s unique blockchain applicability does not allow for changing aliases or profile information currently. Only profile pictures are modifiable in the application Profile settings.

Information we may share

Third Parties. None.

Other instances where Metis Messenger may need to share your data

We collect no data, so we have no data to share.


We will update this privacy policy as needed so that it is current, accurate, and as clear as possible. Your continued use of our Services confirms your acceptance of our updated Privacy Policy.


Please also read our Terms which also governs the terms of this Privacy Policy.
