Privacy

Your video stays on your devices.

Last updated: 13 November 2026

Who we are

CourtMuse is an independent iOS app that turns a tennis match video into rally cuts, estimated shot speeds, a bounce map, and coaching feedback. For privacy questions, contact [email protected].

What the app processes

• Video and photos you choose. The app needs access to the camera or your photo library so you can record or import a match. The video is stored in the app’s local container on your iPhone.
• Court calibration. You tap four court corners. The calibration is stored with the session on your device.
• Analysis data. Rally cuts, estimated speeds, bounce positions, and coaching output are written to the session folder on your device.
• Optional Mac sync. If you choose to sync to a Mac, the app sends the video and session data to the address you enter on your local network. That transfer is between your devices; we do not receive a copy.

What we collect

The app does not include third-party advertising or analytics SDKs. In the current beta build, we do not collect personal data from the app itself.

• Beta list. If you join the waitlist, we collect the email address you submit and use it to send CourtMuse beta and launch updates. You can unsubscribe at any time.
• Support email. If you email us, we receive your email address and the contents of your message so we can reply.
• Website. Our site is hosted by Cloudflare. Cloudflare may process technical data such as your IP address to serve the site and protect it from abuse. We do not use advertising cookies.
• Apple diagnostics. If you opt in to share crash and usage data with developers in iOS settings, Apple may provide us with aggregated diagnostics. This is controlled by you in iOS Settings, not by CourtMuse.

Permissions we ask for

• Camera. To record a match from the court.
• Photos. To import a video you already recorded, and to save an exported reel or frame if you ask.
• Local network. Only if you choose to sync with a Mac on your network.
• Notifications. Only if you enable analysis-complete or beta notifications.

What we do not do

• We do not upload your match video to a CourtMuse cloud service.
• We do not sell, rent, or trade your personal data.
• We do not use your video to train models without your explicit consent.
• We do not require an account to use the app.
• We do not use third-party advertising trackers in the app.

How long we keep data

Your videos and analysis stay on your device until you delete the session or uninstall the app. Beta-list emails are kept until you unsubscribe or ask us to delete them. Support emails are kept for as long as needed to resolve the request and then deleted on a reasonable schedule.

Your choices

• Delete a session in the app to remove its video and analysis from your device.
• Uninstall the app to remove its local data.
• Unsubscribe from beta emails using the link in any email.
• Email [email protected] to ask for a copy or deletion of the data we hold about you.

Children

CourtMuse is not directed to children under 13. If you are a parent or guardian and believe a child has sent us personal data, contact us and we will delete it.

Changes

If our data practices change, we will update this page and change the date at the top. If the change is material, we will tell beta users by email.
