Fluffychat doesn't operate any server or remote service.
All communication of substantive content between Fluffychat and any server is done in secure way, using transport encryption to protect it. End-to-end encryption will follow.

Fluffychat offers the option to use phone numbers to find contacts. This is not a requirement of normal operation and is intended only as a convenience. No contact details are uploaded without user interaction! The user can choose to upload all or some or no contacts to the identity server!
The Matrix server selected by the user will automatically send push notifications to the UBports push service. These notifications are encrypted with the https protocol between the device and the Matrix server and on to the official UBports Matrix gateway at https://push.ubports.com:5003/_matrix/push/r0/notify This server forwards the notification to UBports push service at https://push.ubports.com and then sends this on as a push notification to the user's device(s).
