Privacy Policy

Our Privacy Principles

We built CoachEx with a strong focus on protecting your videos and personal data.

  • Your videos belong to you. Videos you record or upload remain private to your account and are not shared publicly.

  • Most analysis happens on your device. The app analyzes tennis swings locally on your phone or tablet whenever possible.

  • You control whether your data improves the system. Anonymized data is used to help improve our AI coaching features, and this is on by default. You can turn it off at any time in Settings → Privacy.

  • We do not sell your data. Your videos and personal information are never sold or used for advertising.

 

Our goal is to give you useful coaching feedback while keeping your data secure and under your control.

Information We Collect

Account Information
When you create an account, we may collect:

  • Name

  • Email address

  • Account login information

 

This information is used only to provide and operate the Service.

Videos and Coaching Data

On-Device Video Analysis
CoachEx analyzes tennis swings primarily on your device. When you record a video, the video analysis needed to generate coaching feedback is performed locally on your device.


Instead of sending the full video for processing, CoachEx typically uploads only derived numerical analysis results necessary to provide coaching feedback and allow synchronization across devices.


Limited Image Processing

During a Live Coaching session, the app sends a small number of low resolution, black and white still images from your camera so your Coach can respond to what is happening on court. These images are processed by our third party AI providers, are used only to provide coaching in that moment, and are not stored by us or retained by them. Full videos are never sent for this purpose.


Video Storage
Videos may be uploaded to our servers only to support user features such as:

  • accessing videos from multiple devices

  • backing up user content

  • reviewing past coaching sessions

 

Videos stored on our servers are private to your account and are kept secure, never publicly accessible.

Device Permissions

CoachEx may request permission to access certain device capabilities in order to provide its features:

  • Camera: Used to allow the AI Coach to analyze your tennis swings and record tennis videos for you.

  • Microphone: Used only to enable conversation with your Coach within the app.

​

​

  • Your voice is processed as you speak and is not recorded or stored.

These permissions are used only to enable core app functionality and can be controlled in your device settings.

Optional Data Sharing

Improving Our AI System

Your videos are used to improve the accuracy of our swing analysis. This is on by default, and you can turn it off at any time in:

Settings → Privacy → Share videos to improve accuracy

  • If the option is disabled, your videos will not be used for training or improving our algorithms.

  • If the option is enabled, selected data may be used to improve our coaching models.

 

Any data used for training is anonymized and aggregated, and it cannot be connected back to an individual user. Because that anonymization cannot be reversed, turning the option off stops all future use, but it does not allow us to find and remove a specific past contribution.

Anonymous Usage Analytics

Anonymous usage data helps us improve the application. This is on by default, and you can turn it off at any time in:

Settings → Privacy → Share anonymous usage data

Usage analytics may include:

  • feature usage

  • performance metrics

  • crash reports

  • general interaction with the app

This information does not identify you personally and is used only to improve the Service and application.

Your Control

You remain in control of your data. You can:

  • delete videos stored in your account

  • disable uploading of anonymized videos to improve training

  • disable anonymous analytics

  • delete your account

 

Videos stored on our servers as part of your account remain private, secure, and accessible only to you.

​

When you delete your account, all videos, coaching history, ratings, and other personally identifiable information are permanently deleted from our systems within a few minutes. You can delete your account in the app at Settings → Account → Delete my account.

​

We do not sell your data, and we do not share it for advertising.

​

To provide coaching, we use third party AI providers. They process the results of the analysis performed on your device and, during Live Coaching, the low resolution images described above. They may use this data only to provide the Service to you.

​

We also use service providers for hosting, storage and payments. Each receives only what it needs to do its job.

Security

We take reasonable technical and organizational measures to protect user information and stored videos from unauthorized access, loss, or misuse.

Family Use

CoachEx may be used by individuals, coaches, or families practicing tennis together. If the Service is used by or on behalf of a minor, a parent or guardian should supervise use of the Service and manage account privacy settings.

Changes to This Policy

We may update this Privacy Policy from time to time. When changes are made, the updated version will be posted here with the revised date.
