Privacy Policy

Effective date: 21 March 2026  ·  Last updated: 18 April 2026  ·  Version 2.1

Short version: Your baby's sleep logs and your family's personal data stay encrypted on your device. We cannot read it, sell it, or lose it in a breach — because personal sleep logs are not readable by us. The only data on our servers is the minimum needed to run your account.

1. Introduction

Slumbino is a sleep tracking app for babies and new parents. We understand that data about infants and families is especially sensitive. That understanding has shaped every architectural decision in how Slumbino is built.

This Privacy Policy explains what data is collected, where it lives, and your rights under Australian law. Slumbino is a brand of Sleep Portfolio, Queensland, Australia.

2. Children's Privacy — Special Commitments

Slumbino is designed for use by parents and caregivers — not by children. Data entered into Slumbino about your baby (sleep logs, feeding times, growth notes) is treated as your personal data. We never share, sell, or monetise data relating to children.

Slumbino does not knowingly collect personal information directly from children. All account creation and data entry is performed by the adult parent or caregiver. If you believe information relating to a child has been misused, contact sleepportfolio@gmail.com immediately.

3. Zero-Knowledge Architecture

Your family's sleep data stays encrypted on your device.

4. Data We Collect and Store

4.1 On-Device Data (Never Transmitted to Our Servers)

This data is never transmitted to Slumbino servers. We have no access to it.

4.2 Data Transmitted to Our Servers

4.3 Analytics

Analytics events contain: a random session identifier, event type, timestamp, device type and app version. They do not contain your name, email, baby data, or any personally identifiable information.

5. On-Device Storage and Encryption

All data is stored in an encrypted SQLite database using AES-256 encryption. The key is held in your device's secure enclave (iOS) or Android Keystore (Android) and is never transmitted anywhere. Deleting the app permanently deletes all on-device data. We hold no copy.

6. Optional Encrypted Backup

7. AI Sleep Coach

The AI Sleep Coach is powered by the Anthropic API (Claude). When you interact with the Coach:

8. Push Notifications

If you enable push notifications, we store your device push token to send reminders (nap reminders, bedtime alerts). Push tokens are not linked to your personal identity. You can disable them at any time — disabling notifications triggers deletion of your push token from our servers.

9. Payments

Consumer subscriptions are processed entirely through Apple App Store or Google Play, managed by RevenueCat. Slumbino never sees or stores your payment card details.
