Security & Privacy

By leveraging state of the art end-to-end encryption you get the
control to decide who can access your data.

How is your data secured?
    All notes are encrypted and a note can only be decrypted by the
    devices of its collaborators. In addition contact and device
    names are encrypted and can only be accessed by your devices.
    This means Serenity's servers can't decrypt any of your content.
    The servers only act as a transport service of encrypted data
    between devices.
What technology is used?
    The encryption is based on the Double Ratchet Algorithm
    popularised by Signal. It uses the Olm and Megolm implementation
    which is powering the end-to-end encryption of the Matrix
    Protocol. Serenity's protocol is inspired by the Matrix protocol
    but optimized for shared data. The source code of Serenity Notes
    iOS and Android client has been open sourced and is available
    here. More details on the protocol will follow in the future ...

Sign up without an email, phone number or password

Sign up in seconds with just one click without the necessity of
providing an email, phone number or password. The secret keys
generated and stored on your device convert your device into the
authentication mechanism with servers and collaborators.

Collaborate securely

Adding another contact only requires you to connect once by sending
your contact an invitation code.

The video shows how a new contact is added and how an existing note
is shared with the new contact. Furthermore the note is updated and
synced to the contact's device.

Link multiple personal Devices

While it's important to collaborate with others, it's also very
relevant to have your data available and securely synchronized across
all your devices.
