Privacy Policy

1. Scope

This Privacy Policy explains how information is handled when you use the Comet iOS application and this website. “Comet,” “we,” “us,” and “our” refer to the developer of the Comet application.

2. Videos, swing analysis, and shot traces

When you choose a video, iOS provides Comet access only to the item you select. Comet copies and processes the selected video locally to identify swings, create clips, and automatically trace the ball’s flight in each clip. Shot tracing runs on your device. The original video, generated clips, thumbnails, detected body movement, ball-flight paths, and analysis results remain on your device during ordinary processing. Sending a clip for review is a separate, optional action described below.

Those files remain until you delete them in Comet, delete the app, or remove them through device storage management. Exports go only to the destination you select using iOS sharing or saving controls.

Optional clip reviews and pipeline improvement

A thumbs-up or thumbs-down rating sends your feedback and technical diagnostics without a video. If you choose “Agree & send my clip,” you give Comet permission to receive the selected clip, including any audio it contains, your note, and processing diagnostics for both reviewing your report and improving our tracing pipeline, including developing, testing, and training models. This is one optional choice covering both purposes. Declining does not upload your video and does not affect ordinary on-device tracing.

Submitted clips are stored privately using Google Cloud Storage for Firebase. Firestore stores review status, consent records, and results. Firebase Authentication assigns an anonymous app identity so only your app identity and authorized Comet personnel can access your review. App Check helps protect submissions from unauthorized clients. Comet may return a corrected trace or an explanation in the app. We do not post submitted clips publicly or use them in advertising.

Submissions expire after one year and are scheduled for deletion. In Settings → Trace reviews, you can delete a submission to cancel review and withdraw permission for future improvement use. Deletion is processed when the app reconnects; it removes the submitted media and returned result from our review storage. It cannot undo model training already completed. We retain minimal publication audit information without the video or your note. Your original local shot and traces you already applied stay on your device until you delete them.

Deleting a local shot or uninstalling Comet does not itself delete a submitted review. The anonymous identity may not be recoverable after reinstalling or changing devices. For help locating a submission or requesting deletion, contact us with its review ID. Please send only clips you have permission to share, and avoid including sensitive information in a clip or note.

3. Analytics and crash diagnostics

Comet uses Google Analytics for Firebase to understand whether onboarding, scanning, playback, exporting, and purchase flows work as intended. The app may send:

• product interaction events, such as completing an onboarding step, starting or finishing a scan, opening results, viewing a paywall, or attempting an export;
• limited event properties, such as the screen or flow where an action occurred and a broad outcome or error category;
• automatically collected app and device information, including app version, device category, operating-system version, language, approximate region, and an automatically generated app-instance identifier.

Comet also uses Firebase Crashlytics to identify and fix crashes and reliability problems. When an error or crash occurs, Crashlytics may receive crash logs, stack traces, diagnostic and app-state information, a Crashlytics installation identifier, and app or device metadata such as the app version, device model, operating-system version, available storage or memory, and the time of the event. We do not set a Crashlytics user ID or attach your name, email address, or Comet account information; Comet does not require an account.

We do not send video files, clip contents, filenames, Photos library contents, names, email addresses, account IDs, precise location, advertising identifiers, shot-trace geometry, or detected hand or head movement to Analytics or Crashlytics. We do not use this information for targeted advertising or cross-app tracking, and Comet does not access the IDFA for these services.

Google processes Analytics and Crashlytics information on our behalf under its applicable terms, solely to provide measurement, diagnostics, and reliability services to us. Learn more in Google’s Privacy Policy.

4. Purchases

Comet Pro purchases are processed by Apple through the App Store. Apple handles your payment credentials. Comet receives transaction and entitlement information needed to provide or restore Pro access, but we do not receive your full payment-card information. Apple’s handling of purchase information is governed by Apple’s Privacy Policy.

5. Notifications and background processing

If you allow notifications, Comet may schedule local notifications on your device to tell you when processing is complete or remind you about a scan. These notifications are generated locally. Background-processing settings and scan state are stored on your device.

6. Data sharing and selling

We do not sell your personal information. We do not share your videos or swing clips with advertisers or data brokers. Limited analytics and crash-diagnostic information is processed by Google solely to provide measurement, diagnostics, and reliability services to us. Purchase information is processed by Apple to operate App Store purchases.

7. Retention and choices

You can delete imported sessions and clips within Comet. Deleting Comet removes its locally stored app data from your device, subject to iOS behavior and any backups you control. Analytics and crash-diagnostic information is retained according to the retention settings for our Firebase and Google Analytics services. Because Comet does not attach your anonymous review identity to Analytics or Crashlytics information, we may not be able to locate a specific person’s events or crash reports.

You can prevent future Analytics and Crashlytics collection by discontinuing use of and deleting the app. You can manage purchase history and subscriptions through your Apple Account settings. For privacy questions or requests about information we can reasonably identify, contact us using the address below.

8. Children

Comet is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us so we can address it.

9. Security and international processing

We use reasonable safeguards appropriate to the information we handle. No transmission or storage system is guaranteed to be completely secure. Analytics and crash-diagnostics providers may process information in countries other than the one where you live, subject to their contractual and legal safeguards.

10. Changes

We may update this policy as Comet changes. We will post the revised policy here and update the effective date. Material changes may also be communicated in the app when appropriate.
