Step by step

1. 1

   On your device

   Split stores groups, entries and payments on your device first. That's why it works without a connection.

2. 2

   On the server

   So everyone in the group sees the same numbers, Split syncs the data via a server at Amazon Web Services in Frankfurt. The connection is encrypted, and the data is stored encrypted on the server.

3. 3

   Who sees it

   Only its members see a group. Within the group, everyone sees all entries and changes – so it stays clear who entered what.
