Privacy Policy

Last updated: October 2026 · Effective upon App Store release

Who we are

Duobloom ("we", "us", "our") is an educational play companion app for parents and caregivers of young children. This policy explains how we handle information when you use the app.

Data stored on your device

The app stores the following locally on your device using Apple's UserDefaults:

• Your child's profile: a name or nickname, age group, interests, and skill priorities — all entered by you.
• Session history: which activities you played, duration, support level, enjoyment, and stop reason.
• Language preference.

This data never leaves your device in the current version of the app.

What we do NOT collect

• No personal information (email, phone number, real name, location).
• No camera or microphone data.
• No advertising identifiers or tracking.
• No analytics or crash reporting to third-party services.
• No accounts or logins required.

Children's privacy

Duobloom is designed for parents and caregivers to use with young children. The child does not interact with the app directly. We do not knowingly collect personal information from children. The parent or guardian controls all data entry and is responsible for the device.

We comply with applicable children's privacy laws including COPPA (US), GDPR-K (EU), and Vietnam's Decree 13/2023 on personal data protection.

Future versions

If a future version adds cloud sync, family sharing, or accounts, we will:

• Update this policy before the feature launches.
• Request clear, verifiable parental consent before transmitting any data.
• Apply the minimum data principle — only collect what is strictly necessary.

Data deletion

You can delete all app data at any time by deleting the app from your device. In the current version there is no server-side data to request deletion of.

Third-party services

The current version of Duobloom uses no third-party SDKs, analytics, advertising networks, or external services.

Reference information

The knowledge hub contains general reference information (growth standards, developmental milestones, sleep guidelines) drawn from publicly available sources such as WHO and CDC. This information is not personalised medical advice. For any health or development concern, consult a qualified professional.

For privacy questions, contact us at: support@duobloom.app (or the support email you register with App Store Connect).

Changes to this policy

We will update this page if our data practices change. Continued use of the app after an update constitutes acceptance of the revised policy.
