Mozi stores your account, conversations, files, reminders, device tokens and usage records to operate your assistant. Your assistant runs in a dedicated tenant space. Google credentials stay in a separate authorization service; model providers receive the content needed to answer your request.
Apple Health (optional, read only): when you allow it on your iPhone, Mozi reads workouts, steps, active energy, sleep, weight, resting heart rate and period dates. Your phone summarises them and sends only those summaries to your own assistant space to answer you or record a habit you set up; they are kept there like the rest of your conversation and deleted with your account. Mozi never writes to Health, does not store Health data in the account service or iCloud, and never uses it for advertising, marketing or selling to third parties. Model providers receive only the summaries needed to answer your request. You can turn reading off at any time in the Health app.
You can request account deletion in the app. It revokes Google access and removes your tenant storage and identifiable service records. Encrypted backups currently have no automatic expiration policy; copies may remain until the operator removes them. Contact [email protected] for backup deletion requests.
