Your personal book stays on your iPhone
Your personal book and solo period books are stored only on your iPhone and never sent to our server (when you use a transfer code, we briefly hold the data encrypted, in a form we can't read). Shared books are stored on our server in Tokyo (AWS) so members can sync. No ads, no analytics, no tracking, and we never sell your data.
