Privacy policy

Effective date: 15 November 2026

Muay Thai Coach is an app made by Kineto-Soft ("we"). This policy explains what data the app uses and what happens to it.

1. Signing in with Apple or Google

You only sign in to rate videos. With Google, Google gives the app your name, email address and Google account ID. With Sign in with Apple, Apple gives the app an Apple user ID and the email you choose to share, which can be a private relay address from Hide My Email. The app doesn't ask Apple for your name. With each request, the app sends a sign-in token to our server. The server checks it and stores only:

• your Apple or Google account ID
• your email address (with Apple, the one you chose to share, if any)
• the date you first signed in
• how many videos you rated today and this month
• how many ratings you got back this month because the video didn't show the training you picked

We don't store your name. We use this only to sign you in and to count how many videos you rate. We never get your Apple or Google password.

2. Videos you choose to rate

When you tap Record a round or Pick a video on the Rate screen, the app uploads that video to our server. The video can show you, anyone else in the frame (such as a pad holder), your surroundings, and the sound your camera recorded. We use it only to create your rating. Before your first rating, the app asks you to agree to this.

• The upload uses an encrypted connection (HTTPS).
• Our server keeps the video in a temporary file only while it's being analyzed, then deletes it.
• Our server sends the video to Google's Gemini API, which analyzes it and returns the rating. We delete the video from Google's storage as soon as the analysis is done. Google also deletes uploaded files automatically after 48 hours.
• The rating result (score and feedback text) is stored on our server with your Apple or Google account ID until your app confirms it saved the result, for at most 24 hours. Then it's deleted. This way a crash or a lost connection doesn't cost you a rating.

Google processes the video for us under the Gemini API Additional Terms of Service. We use the paid Gemini API service, under which Google doesn't use your content to improve its products.

Please don't film other people without their permission.

3. Muay Thai Coach Pro subscription

Pro is sold through the App Store (iPhone, iPad) or Google Play (Android), and the store handles the payment. We never see your card or bank details. We use RevenueCat to know whether your subscription is active. RevenueCat gets a random ID from the app. If you sign in to rate videos, it gets your Apple or Google account ID instead, so your subscription works on all your devices and our server can check it. Apple or Google Play sends RevenueCat your purchase details: which plan, the purchase and renewal dates, and whether it's active. Before our server allows more ratings, it asks RevenueCat whether you have Pro. The terms of use explain renewal, cancelling and refunds.

4. Reporting a rating

If you report a rating, we store the rating text and the reason you picked. A report isn't linked to your account. We use reports only to improve the ratings.

5. Data stored on your device

Your past ratings (score, feedback text and date) are saved only on your device. They're deleted when you delete your account, clear the app's data, or delete the app. We can't see them. A new result waits on our server only until your app has saved it, 24 hours at most (see section 2).

6. Server logs

Like most web servers, our server records technical request data such as IP address, time and the requested address. We use these logs only for security, fixing problems and counting website visits, and we delete them after 30 days.

7. Permissions

• Camera: to record a video, only when you tap Record a round.
• Microphone: for the sound of that video, only while you film it. On Android, the phone's camera app records the sound.
• Videos: Pick a video opens your device's picker, and the app gets only the video you choose.
• Notifications: only if you turn on training-day reminders. They're set on your device; we don't send push messages.
• Internet: to check your subscription, download app updates, sign in, upload videos for rating and receive the result.
• Vibration: for the round timer.

The app doesn't access your location or contacts.

8. Sharing

We don't sell your data and we don't use it for advertising. Apple and Google handle sign-in and payments, Google's Gemini API analyzes the videos you rate, and RevenueCat checks subscriptions, as described above. When the app starts, it asks Expo's update server (EAS Update) whether there's an app update; Expo gets your IP address and a random install ID for that. They work for us as service providers. We don't share your data with anyone else.

9. Deleting your account

In the app, on Home, tap the person button at the top right to open Profile. Under Data and account, tap Delete account. This removes everything our server stores about your account right away, and the rating history on your device. If you signed in with Apple, we also ask Apple to revoke Muay Thai Coach's Sign in with Apple access; you can also remove it yourself under Sign in with Apple in your Apple Account settings. You can also ask us to delete your account without the app. Deleting your account doesn't cancel a Pro subscription. On iPhone or iPad, cancel it in Settings › your name › Subscriptions; on Android, in Google Play under Payments and subscriptions.

10. Adults only

Muay Thai Coach is for adults 18 and older. It isn't directed at anyone under 18, and we don't knowingly collect data from them. The app asks you to confirm you're 18 or older before your first rating. If you think someone under 18 sent us data, write to us and we'll delete it.

11. Changes

If this policy changes, we'll update this page and the effective date above.

12. Contact

Kineto-Soft · info@kineto-soft.com

You can also write to us from the app (Profile › Contact us). Your message, and your email address if you give one, go to our server, which sends them to our inbox through our email provider. Our server doesn't keep a copy. We use them only to answer you.
