Your privacy is paramount.
QuickSync Whiteboard stores data only on your devices and Apple’s iCloud servers.
To keep your documents in sync data is sent using industry-standard TLS encryption over the local network and through Pavonine Software’s “Relay” server.
This server only ever sees your document in an encrypted form. The encryption keys for your data are stored on Apple’s servers, on your devices, and on the devices of your collaborators.
Pavonine Software does not keep logs of connections to and from the relay server. Your IP address, nor any metadata related to which documents are being edited, are not persisted.
