Privacy Policy

App: Momo Dictation (默書不求人)
Last updated: 20 June 2026

This Privacy Policy explains how Momo Dictation ("the app", "we", "us") handles your information. We built this app to help parents and tutors in Hong Kong run Chinese and English dictation practice with their children. We collect as little data as possible.

1. Information we collect

Account information

When you sign in with Apple or Google, we receive a user ID and your name and email address (or, if you use Apple's "Hide My Email", a private relay email). This is handled through Google Firebase Authentication and is used only to create and secure your account.

Photos you scan

If you use the "scan from photo" feature, the photo you take is sent to our secure server (a Firebase Cloud Function), which forwards it to Google Cloud Vision to recognise the text on the page. We use the photo only to extract the words for your dictation list. The photo is processed at that moment and is not stored on our servers.

Selfie photos

If you use the camera/selfie feature with the Momo mascot, those photos stay on your device and are saved only to your own photo album. They are never uploaded to us or anyone else.

Your lists and settings

The dictation lists, tags and playback settings you create are stored on your device. If account sync is enabled, they may also be stored in your account so you don't lose them.

2. What we do NOT do

3. Third-party services

The app relies on these services, which have their own privacy policies:

4. Children's privacy

The app is intended to be set up and managed by an adult (a parent or tutor). Accounts are created by adults. We do not knowingly collect personal information from children. The photos you scan are of textbook or worksheet pages, not personal data about a child.

5. How to delete your data

You can delete your account and the data associated with it from within the app, or by emailing us at the address below and we will delete it. Lists stored only on your device are removed when you delete the app.

6. Data security

We use reputable providers (Apple, Google Firebase) and industry-standard security to protect your information. No method of transmission over the internet is 100% secure, but we take reasonable steps to protect your data.

7. Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top shows when it last changed.

8. Contact
