How do I cancel my subscription?
Subscriptions are managed by Apple. On your iPhone, open Settings, tap your name, then Subscriptions, choose Slpy and tap Cancel Subscription. Cancel at least 24 hours before the renewal date to avoid being charged for the next year. Deleting the app does not cancel the subscription.

How do I delete my data?
Open Settings in Slpy and choose “Delete account & data”. This erases the baby profile, plan, sleep logs and chats on your device and deletes your anonymous account record on our server. A device marker is kept so the free trial isn’t granted twice. Deleting the app also removes its local data.
