Math by Voice / Математика голосом

Last updated: July 8, 2026

Short version: Math by Voice does not require an account, does not show advertising, does not use third-party analytics, and does not sell or share personal data. Voice features use the speech recognition services provided by the operating system.

1. Introduction

Math by Voice is a voice-first mathematics learning app with practice activities, tests, and interactive lessons. This Privacy Policy explains how information is handled when the app is used on iPhone, iPad, or Android devices.

2. Information We Do Not Collect

The developer does not collect personal data for its own use. In particular:

No account registration is required.
We do not collect names, email addresses, phone numbers, or contact lists.
We do not collect precise location data.
We do not collect device identifiers for tracking.
We do not use cookies or cross-app tracking technologies.
We do not sell personal data.

3. Voice, Microphone, and Speech Recognition

The app is designed around spoken interaction. Microphone and speech recognition permissions are requested so users can answer math questions and interact with learning activities by voice.

The developer does not receive, store, or listen to voice recordings.
The developer does not operate a server that receives speech audio from the app.
On Apple devices, recognition may be provided by Apple Speech Recognition.
On Android devices, recognition may be provided by the speech recognition service configured on the device.
Depending on the device, language, settings, and network availability, audio may be processed on device or by the operating-system provider.

Users can revoke microphone or speech recognition permission at any time in device settings.

4. Analytics, Advertising, and Third Parties

The app does not include third-party advertising SDKs and does not use third-party analytics SDKs. The developer does not share user or device data with third parties for advertising, analytics, or profiling.

5. Children’s Privacy

The app is educational and may be used by children. We do not knowingly collect personal information from children. The app does not contain social networking features, external advertising, or account registration.

6. Local Data Stored on the Device

The app may store basic app settings and learning progress locally on the user’s device, such as:

language preference or device-language behavior;
scores, streaks, and progress statistics;
difficulty and session settings.

This information is stored locally for app functionality. The developer does not receive it. Users can remove local app data by deleting the app from the device.

7. Internet Connection

Some speech recognition features may require an internet connection depending on the operating system and device configuration. The app itself does not require a developer account or developer server login.

8. Changes to This Policy

We may update this Privacy Policy from time to time. If we make changes, we will update the “Last updated” date on this page.
