Professor Ary: Baby Sleep is designed with privacy and calm in mind. The free tier needs no account, and baby profiles and sleep records stay on your device unless you choose Sleep+ cloud backup.
Subscriptions and purchases are processed directly by Apple through the App Store. RevenueCat processes anonymous app user identifiers and Apple transaction receipts to verify entitlement status. We never see or store your payment details.
Professor Ary: Baby Sleep uses a first-party, privacy-minimized analytics service hosted in our Supabase project. Product events may include a random app-installation identifier, event name and time, app version and build, locale, access tier, surface or trigger, selected plan or experiment label, and coarse prediction-quality buckets. They never include names, birthdays, baby or household IDs, Apple or Sleep+ account IDs, invite tokens, raw sleep timestamps, notes, contacts, location, advertising IDs, or free-form error text.
The installation identifier is not linked to an Apple or Sleep+ account and is not used for advertising or cross-app tracking. The app contains no third-party analytics SDK, advertising tracker, or data broker integration. Supabase may process network information transiently to deliver and secure the service. Raw product-event rows are automatically deleted 13 months after receipt. We do not sell or monetize personal data.
You can delete your cloud account and all associated household cloud data at any time in Settings → Account. Account deletion is permanent and separate from App Store subscription management. The anonymous analytics installation identifier is deliberately not linked to the cloud account, so those minimized events follow the separate 13-month deletion schedule.
