Monami — Privacy Policy

Last updated: 2026-06-23

Monami is a friendly bilingual (Vietnamese/English) voice companion for young children. This policy explains what data the app handles and how. It is written plainly for parents.

Who we are

Monami is a small, independent project. Contact: phucnt0@gmail.com.

There are no user accounts. The app identifies a device by a random, anonymous identifier generated on the device — it is not linked to your name, email, phone number, or any real-world identity.

What data we handle

Child profile (you create it):

• Child's first name (as you type it), gender, age, and interests.
• Stored on our backend (Google Cloud Firestore, United States), keyed to the device's anonymous identifier.

Conversation memory:

• After a chat, a short text summary of what the companion learned (e.g. "likes dinosaurs") is stored, so it can greet the child warmly next time.
• You can view, edit, or delete this memory at any time in the app, and you can delete a child entirely (which deletes their profile and memory).

Child's voice (audio):

• While the child talks, audio is streamed in real time to Google Vertex AI (Gemini) to understand speech and reply. This is required for the app to work.
• Audio is not stored by us or on the device — it is processed live and discarded. Only the short text summary above is kept.
• Google processes this audio as our AI provider; see Google Cloud's terms.

Guest mode:

• If you use "Khách (chơi nhanh)" / Guest, nothing is stored — no profile, no memory. The session is forgotten when you leave.

What we do NOT do

• We do not sell or rent your data.
• We do not use third-party advertising or analytics SDKs.
• We do not ask for or collect contact info, location, photos, or contacts.
• We do not create accounts or track you across other apps.

Children's privacy

Monami is designed for young children and is intended to be set up and supervised by a parent or guardian. The only personal data is what a parent chooses to enter (name, gender, age, interests) plus the conversation summaries described above, all tied to an anonymous device identifier. A parent can review and delete this data in the app at any time. For questions or deletion requests, email phucnt0@gmail.com.

Data retention & deletion

• Profiles and memory are kept until you delete them in the app (delete a child, or clear a child's memory).
• Deleting the app does not by itself delete server-side data, but you can request full deletion by emailing phucnt0@gmail.com with no need to identify yourself beyond the request.

Where data is processed

• Backend + storage: Google Cloud (Firestore, Cloud Run) in the United States.
• AI speech/voice: Google Vertex AI (Gemini) in the United States.

Changes

We may update this policy; the "Last updated" date above will change. Material changes will be noted in the app's release notes.
