Privacy Policy

DreamBook — by Niyoko Studio — Last updated: May 2026

DreamBook is designed around your family's privacy. No login. No account. No email address required. Your baby's data stays on your device, encrypted, and only you hold the keys.

1. Who We Are

DreamBook is developed and published by Niyoko Studio. If you have any questions about this policy, you can reach us at:

supportniyoko@gmail.com

2. No Account Required

DreamBook does not require you to create an account, provide an email address, or log in with any third-party identity provider. You start recording your baby's logs immediately without sharing any personal identity information with us.

3. What Data the App Records

DreamBook stores the following data locally on your device:

We do not collect names, email addresses, phone numbers, location data, photos, or any other information beyond what you explicitly enter into the baby log.

4. How Data Is Protected on Your Device

All data stored locally is encrypted at rest using SQLCipher (AES-256). The encryption key is stored in your device's secure hardware enclave (iOS Keychain / Android EncryptedSharedPreferences). An attacker with physical access to your device cannot read your baby logs without your device passcode.

Android app data backup is disabled (allowBackup="false") to prevent unencrypted database snapshots from leaking to Google Drive.

5. Optional Cloud Sync

DreamBook offers an optional encrypted cloud sync feature so you can share logs with co-caregivers or restore data to a new device. If you choose to use this feature:

If you do not use cloud sync, no data ever leaves your device.

6. Recovery Code

When you set up cloud sync, the app generates a 20-character recovery code. This code:

You are responsible for saving your recovery code. If you lose it and lose your device, your cloud data cannot be recovered — not even by us.

7. Analytics and Crash Reporting

DreamBook does not include any advertising SDK or behavioral analytics SDK.

Optional crash reporting (via Sentry/Crashlytics) is available to help us fix bugs. This feature is disabled by default. You can opt in from Settings. If enabled, crash reports may contain device model, OS version, and a stack trace. They do not contain baby log data.

8. Advertising

DreamBook contains no advertisements.

9. Children's Data (COPPA / GDPR-K / PDPA)

DreamBook is designed to track data about infants and toddlers aged 0–24 months. All such data is entered by a parent or caregiver and is covered by the protections described in this policy. We do not knowingly collect personal information from children directly; the app is operated by parents on their devices.

If you believe we have inadvertently collected data about a child in a way not covered here, please contact us immediately at supportniyoko@gmail.com.

10. Your Rights

Because we do not operate accounts or link data to identifiable individuals, most traditional privacy rights (access, portability, objection) are fulfilled automatically — you already hold all your data on your device.

For cloud sync data, you have the right to full erasure:

11. Data Retention

12. Third-Party Services

DreamBook uses the following third-party services:

We do not sell, rent, or trade your data to any third party for marketing or advertising purposes.

13. Changes to This Policy

If we make material changes to this privacy policy, we will update the "Last updated" date at the top of this page and, where appropriate, notify you within the app. Continued use of DreamBook after a policy change constitutes your acceptance of the revised policy.
