Multiply Master (Core)

Effective date: July 22, 2026

Overview

Multiply Master (Core) ("the App") is an offline educational app that helps children practice multiplication tables 1 through 10. This policy explains what information the App uses, where it is stored, and the choices available to parents and guardians. A shorter version of this policy is also available inside the App itself, under Settings → Privacy Policy.

      The short version: the App has no server and no user
      accounts. Everything you enter — a child's name, school, class, and chosen
      avatar or photo — is saved only in the device's local storage and is never
      transmitted to us or to any server we operate.
    

Information the App Uses

When a profile is first set up, the App asks for:

Name (required) — used only to personalize the in-app experience and any certificates the child earns.
School name and class/grade (optional) — shown on earned certificates if provided.
An avatar or a photo (optional, mutually exclusive) — used only to personalize the profile and certificates. If a photo is chosen, it is resized on-device to a small, low-resolution image before being stored.

The App also tracks gameplay progress locally (stars earned, stages completed, and light/dark theme preference) to save progress between sessions.

None of the information above is collected by us. It is written to the device's local storage using standard web storage APIs and stays on the device. We do not operate a server that receives, stores, or has access to this information. We cannot see it, and we do not sell, rent, or share it with anyone, because we never receive it in the first place.

Certificates

When a child completes a multiplication table, the App can generate a certificate image locally on the device. Saving or sharing a certificate uses the device's own share options (for example, saving to the device's photo storage or sharing through another app the parent has installed). That sharing action is initiated by the user and is subject to the privacy practices of whichever destination they choose — the App itself does not upload the certificate anywhere.

Advertising

If this App displays advertisements, they are served using Google AdMob. In that case:

Ads shown to children are configured for child-directed treatment, meaning no personalized or interest-based advertising is used.
The advertising identifier is not transmitted for users identified as children.
Only ad networks that meet Google Play's Families Ads Program requirements are used.

Google's own privacy practices for AdMob are described at policies.google.com/privacy.

If the version of the App you are using does not currently show advertisements, this section describes how ads will be configured if they are enabled in a future update.

Children's Privacy

This App is directed at children and is designed with that audience in mind. We do not knowingly collect personal information from children beyond what is described above, all of which remains on the child's own device. We do not require account creation, email addresses, or any contact information to use the App.

Parents and guardians can review, change, or delete all stored information at any time by:

Using the "Reset All Stars" option inside the App's Settings menu (a simple math question keeps this, and other grown-up options, out of reach of young children), which clears saved names, school, class, avatar/photo, and all progress, or
Uninstalling the App, which removes all locally stored data immediately.

Data Security

Because information is stored only on the device and never transmitted by the App, there is no server-side database of user information that could be exposed in a data breach. Standard device-level protections (such as the device's own lock screen and storage encryption, where enabled) apply to this data the same as to any other app on the device.

Third-Party Services

The App may rely on standard Google Play Services and, if enabled, Google AdMob (see "Advertising" above). We do not integrate any analytics, crash-reporting, or tracking SDKs beyond what is described in this policy. If that changes in a future update, this policy will be updated before the change takes effect.

Changes to This Policy

We may update this policy from time to time, for example if a future version of the App adds a new feature that changes what information is used. The "Effective date" above will always reflect the most recent version. Continued use of the App after an update constitutes acceptance of the revised policy.
