About
About Talkivelle
Talkivelle is a notes app and a messenger in one, for people in the same office or home. It works without the internet: devices on the same network find each other and talk directly. There is no server and no account, and your notes and messages stay on your own computers.
Write and organise notes in folders, chat with the people around you, send them files, and call them with voice, video and screen sharing. Share a note and edit it together in real time. When you are apart, keep working: changes and messages sync the next time both devices are online.
Private by design
- Every connection between devices is encrypted (mutual TLS), and you approve each new device by comparing an 8-character code.
- Nothing is sent to Kodonic or anyone else. Data lives in your own data folder and survives updates and uninstalling.
- Back up all your notes to a plain
.zipat any time.
