Privacy Policy

Last updated: August 25, 2026

Mumu Words is a first-words app for young children growing up bilingual or trilingual. It was built by a parent, for families — and it is designed so that there is simply nothing to collect.

What we collect

Nothing.

Mumu Words does not collect, store, transmit, sell, or share any personal information or usage data — from children or from adults.

  • No accounts. The app has no sign-up, login, or profiles.
  • No ads. The app contains no advertising of any kind.
  • No tracking or analytics. No third-party analytics, tracking SDKs, or advertising frameworks.
  • Learning content stays offline. Cards, family photos, voice recordings, weekly decks, and first-word milestones remain on the device and are not sent to Mumu Words or any third party.
  • Microphone use is parent initiated. Microphone permission is requested only when a grown-up chooses to record a custom-card word or item sound. Recordings stay in protected local storage and can be re-recorded or deleted by the parent.
  • Camera use is parent initiated. Camera permission is requested only when a grown-up taps Take Photo for a family card. The app removes metadata, creates smaller private copies, and keeps them on the device.
  • Purchases are handled by Apple. An optional Mumu Words Pro purchase uses Apple's StoreKit. Mumu Words does not receive or store payment information.

The app's settings and parent-created content are stored only on your device. Deleting the app can remove family cards, recordings, decks, and keepsakes unless they are preserved by the device's normal backup and restore process. StoreKit may contact Apple to display product information, complete a purchase, restore a purchase, or verify access according to Apple's privacy policy.

Children's privacy

Mumu Words is made for children ages 0–5 and complies with the Children's Online Privacy Protection Act (COPPA) and Apple's Kids Category rules the simplest way possible: it collects no data at all. The parents' settings area is protected by a parental gate.

Changes to this policy

If a future version of the app ever changes any of the above, this policy will be updated before that version is released.
