Speak Coach Privacy Policy

Speak Coach (“the app”) is an English speaking coach for IELTS, TOEIC and everyday conversation, published by FightTech. This policy explains what the app does with your voice, your answers and your purchases. Short version: there is no account, and the free Android app shows ads from Google AdMob (none while you have Pro or after you buy a credit pack). Your recordings stay on your phone. Answers leave the phone only when you choose Speak Coach AI and agree to the in-app disclosure, or when you use a feature that is online by nature (the weekly league, a teacher’s class, purchases).

1. What stays on your phone

• Your recorded answers, their transcripts, scores, reports, word decks and progress.
• Your learning profile: goal, target band, exam date and the stories or job description you enter for interview practice.
• Settings, including the AI engine you chose and, if you entered one, your own API key. The key is stored on the device and is only sent to the endpoint you configured.

There is no user account and nothing is synced to a cloud. Deleting the app deletes everything stored on your device.

2. Permissions

• Microphone: to record the answers you practise. Recording only happens while you hold or tap the record button.
• Camera (optional): shows your own face during the video-call mock exam, like a mirror. The camera image is never recorded, stored or sent.
• Photo library (optional): to pick an audio or video file to import, for example a lecture to learn words from.
• Local network (optional, iOS): only if you connect your own model server on your network.

Spoken prompts are read aloud with the text-to-speech voices built into your phone.

3. AI processing

You choose the engine in Me › AI engine. On iPhone and iPad, the app starts on the phone’s own engine and never picks a cloud engine for you.

Engine	Where your answer goes
On device	Nowhere. Speech is transcribed by a model on the phone and scores are estimated there. Nothing leaves the phone.
Speak Coach AI (credits)	Our gateway at fighttech.vn, which forwards each request to one of the AI model providers we use: Moonshot AI (Kimi), Xiaomi (MiMo), MiniMax or Zhipu AI (GLM). Some premium grading requests go to Google Gemini. The providers process the request to return the result, under their own terms, and may do so outside your country, including in China and the United States. We keep usage records (token counts and credits) for billing; we do not build a profile of you.
Your own API key	Directly to the endpoint you configured. We never see it.

With Speak Coach AI the app sends, for each answer you submit for grading: the audio of that answer, its transcript, and the text of the task (the question, topic or role-play turn). For lecture practice it sends the audio file you imported, to transcribe it and pick out words. It never sends your name, email, contacts or photos.

Speak Coach AI is off until you turn it on. The first time you choose it, the app shows what will be sent and who receives it, and asks for your agreement; “Not now” sends nothing. You can withdraw your agreement or switch back to the on-device engine at any time in Me › AI engine.

We use your answers only to grade them and return the result to you. We do not sell them, use them for advertising, or use them to train our own models.

4. Weekly league and classes

If you join the weekly league, the app sends the nickname and avatar you choose, a random install id and your weekly practice score to fighttech.vn so they can be ranked with other learners. Other learners see your nickname, avatar and score.

If you join a teacher’s class with an invite link and hand in an assignment, the app sends your nickname, your band scores and a short excerpt of your answer’s transcript to that class on fighttech.vn, where the teacher can read them. A teacher who creates a class uploads the assignment’s title and tasks. Class data expires with the assignment.

5. Purchases

Speak Coach Pro subscriptions and credit packs are sold through the App Store (and Google Play on Android). Payment is handled entirely by Apple or Google; we never receive your card details. To confirm a purchase, the app sends the store receipt, the product id and a random install id to our billing endpoint (fighttech.vn/api/v1/billing/verify), which checks it with the store and returns your Pro status or the credits to add. The install id contains no name, email address or account of yours. Manage or cancel a subscription in your App Store account settings, or on Android in Google Play › Payments & subscriptions.

6. Analytics and ads

Speak Coach does not send analytics or crash reports. The shared engine it is built on contains Google Firebase libraries, but Speak Coach does not turn them on. Downloads of question banks and pronunciation lessons carry no personal data.

The free Android app shows ads from Google AdMob: a banner, possibly a full-screen ad between activities, and optional rewarded ads you can choose to watch to unlock Speak Coach Pro for 30 minutes. Google may use the advertising ID, device information, approximate location derived from the IP address and your interactions with ads to show and measure ads. Where the law requires it (for example in the EEA and the UK), the app first asks for your consent through Google’s consent form (UMP), and you can change your choice at any time under the privacy options in Settings. You see no ads while you have Pro (an active subscription or the lifetime purchase), after you buy a credit pack on this install, and during the 30-minute Pro window unlocked by a rewarded ad. If a subscription ends, ads come back. Your recordings and answers are never sent to AdMob. We sell no data and build no advertising profile ourselves. How Google uses data from apps that show its ads: policies.google.com/technologies/partner-sites. You can reset or delete the advertising ID in the Android settings, under Privacy → Ads.

7. Who receives data

• FightTech (fighttech.vn): the Speak Coach AI gateway, the weekly league, classes and purchase verification described above.
• AI model providers, only when you use Speak Coach AI: Moonshot AI (Kimi), Xiaomi (MiMo), MiniMax, Zhipu AI (GLM) and Google (Gemini).
• Apple and Google, for payments.
• Google AdMob, for ads in the free Android app.
• The endpoint you configure, when you use your own API key, under that provider’s terms.

8. What we do not do

• No advertising profile built by us and no tracking by us across other apps or websites; the ads in the free Android app are described in section 6.
• We do not sell personal data, and we share it only with the recipients listed above, to run the features you use.

9. Children

The app is not directed at children under 13 and we do not knowingly collect data from them.

10. Deleting your data

Everything on the phone is deleted when you delete the app; interview stories can also be deleted inside the app. To remove your league entry or class submissions from our servers, email us with the nickname you used and we will delete them within 30 days. Requests sent to AI providers are not kept by us beyond the usage records needed for billing.

11. Changes and contact

If this policy changes in a way that affects what is sent, the app asks for your agreement again before sending anything.
