Speak Master Privacy Policy

Effective date: October 5, 2026

Speak Master is a speaking and listening practice app for learning languages. This Privacy Policy explains what information we collect, how we use it, who can see it, and how users can contact us about their data.

Information We Collect

• Anonymous app account identifiers created through Firebase Authentication. We do not ask for your name, email address or phone number to use the app.
• Learning settings such as app language, native language, learning language, level, weekly progress, practice history, review items and study time.
• Voice recordings submitted during speaking practice, related transcripts, scoring results and evaluation metadata.
• Study activity used for streaks, weekly goals and points: study days, effective study time, practiced items and answer accuracy.
• Feedback messages and problem reports submitted through the app, including screenshots you choose to attach.
• App diagnostics, device information and usage events used to maintain and improve the app.
• Purchase records for the ad-free premium subscription (verified with Google Play).
• Push notification tokens for your device, used only to deliver the app's own notifications.

Study Groups

Study groups (including 1:1 study partners) are optional. If you use them, we also process:

• Nickname — a unique nickname you choose. It is shown to members of the groups you join.
• Shared learning progress — other members of your groups can see your learning language, level, week and current practice step, your progress through the curriculum, today's study time and practiced items, and your monthly study statistics. This is shared only with members of groups you have joined.
• Online status — while the app is open, it records whether you are online or currently studying, and when you were last active, so that group members can see it and so that we do not send you notifications while you are using the app.
• Group chat — messages you send in a group are visible to its members and are stored for 30 days. System notices (joins, leaves, goals) are stored for the same period.
• Reports and blocks — if you report a message, we store the report, the reported message and the accounts involved so our operators can review it. Users you block are stored in your account so their messages are hidden from you.
• Group goals and rewards — monthly goal results and any points awarded.

Inappropriate content (harassment, hate speech, sexual content, spam or advertising, sharing personal information) is not allowed. Reported content is reviewed; violations can lead to message deletion, removal from groups or account restrictions. Do not share personal information in group chat.

How We Use Information

• To provide speaking, listening, pronunciation, lesson progress, review, streak, goal and point features.
• To process recordings for speech recognition, scoring and language-learning feedback.
• To provide study groups: sharing progress with your group members, group chat, monthly group goals and the daily group briefing.
• To send notifications you have allowed, such as study reminders, group encouragement, chat messages and the daily briefing. Group notifications are not sent between 22:00 and 08:00 in your local time.
• To save your progress and synchronize app content.
• To respond to feedback, problem reports and support requests, and to review reported content.
• To monitor reliability, prevent abuse and improve the app.

Service Providers

We use trusted service providers to operate the app, including Firebase and Google Cloud for authentication, database, storage, hosting, cloud functions, push notifications (Firebase Cloud Messaging), speech recognition, text-to-speech, analytics and diagnostics. We may also use AI service providers to generate or evaluate language-learning content. These providers process information only as needed to provide app functionality.

Advertising And Purchases

The free version of Speak Master shows ads through Google AdMob. AdMob may collect device identifiers such as the advertising ID and usage information to serve and measure ads; see Google's privacy policy for details. You can reset or limit the advertising ID in your device settings. An optional ad-free premium subscription is sold through Google Play; payment is handled by Google Play, and we receive only the information needed to verify the subscription. Premium can also be obtained with points earned in the app.

Data Retention And Deletion

We keep user data for as long as needed to provide the app, maintain security, comply with legal obligations and improve service reliability. Group chat messages are deleted after 30 days and daily briefings after 14 days. When you leave a group, your shared progress is removed from that group. Users may request deletion of their app data as described on our account and data deletion page or by contacting us at the email address below.

Children

Speak Master is not directed to children. Users who are not old enough to use online services independently in their country should use the app, and in particular study groups and group chat, only with a parent or guardian.

Changes To This Policy

We may update this Privacy Policy when the app changes or when legal, technical or business requirements change. The effective date above will be updated when material changes are made.
