Simple privacy summary: We do not sell personal information, run behavioral advertising, or use your swing videos to train artificial-intelligence models. The initial mobile release does not include student–coach messaging.

Information we collect

Account and profile information

We collect a username, a protected password representation, account role, account and sign-in timestamps, and account status. If you choose to add them, we may also store an email address, phone number, and profile information. Registration uses the birthday you select only in the form to determine an age group: under 13, 13–17, or 18 and older. The birthday itself is not sent to our servers or saved. Under-13 registration is blocked. We retain the account age group, not a birthdate. Ages 13–17 have limited accounts: username, protected password, lesson/practice completion and quiz progress, plus the identifiers, sessions, timestamps, and security records needed to operate and protect the account. Teen accounts do not collect profile photos, email, phone, free-text notes, swing scores, or videos. Optional profile fields described above are available only to adults.

Learning, progress, and practice information

We store curriculum progress, completed activities, quiz results, notes you enter, and synchronization records needed to keep progress associated with the correct account. Practice-session records created by earlier beta versions may remain in your account data until you delete your account.

Retired beta features

Focus Mode is not available in the current app. The current build does not request microphone, motion, music-library, or location access. Earlier beta versions used those permissions only while Focus Mode was active.

Swing-review information

The on-device Swing Analyzer processes the video you select on your device; selecting a video for this analyzer does not upload it. If you separately choose to upload a video for private swing review where that feature is available, we collect the uploaded video, its filename and technical details, your notes, review status, and any coach analysis associated with the submission. Uploaded videos are private and are not intended for public posting.

Support and security information

If you contact us, we receive the information in your message and the email address you use. We also process limited request, session, rate-limit, security-event, and technical-diagnostic information to operate the service, prevent abuse, investigate problems, and protect accounts. Diagnostics are limited to coarse failure type, app area, platform, release, response-status and timing ranges, and a random request identifier. They do not include error messages, stack traces, full URLs, usernames, passwords, message bodies, or video content.

Information kept on your device

The website or app may keep your theme, locally selected profile image, sign-in state, progress synchronization data, and temporary upload state on your device. Clearing site/app storage or uninstalling the app removes device-only information but does not itself delete your server account.

The on-device Swing Analyzer keeps up to four recent completed analyses, including their selected videos, filenames, results, and body/club overlay points, so you can review them without analyzing again. These saved analyses are not uploaded or used for training. A new saved analysis replaces the oldest; you can also clear them from Analyze. Signing out or deleting your account clears this local history. Removing saved analyses does not delete your original videos from Photos or Files.

How we use information

When information is shared

We do not sell personal information or share it for cross-context behavioral advertising. We disclose information only as needed to operate the service, when you direct us to, to protect users and the service, or when legally required.

Retention and deletion

InformationNormal retention
Active account, profile, and progressWhile the account is active. Inactive accounts are scheduled for notice after 23 months without login and deletion after 24 months unless use resumes.
Pending original swing videoUp to 90 days after upload.
Completed original swing videoUp to 30 days after analysis delivery.
Coach-analysis videoUp to 180 days after delivery.
Operational logsUp to 30 days.
Security and abuse-prevention recordsUp to 90 days, unless a documented incident requires longer preservation.
Support requestsUp to 24 months after closure, unless an active dispute or legal obligation requires longer retention.
Approved encrypted backupsRolling expiry of no more than 30 days, with deletions reapplied after restoration.

After a verified account-deletion request, access is revoked and associated active-system account, profile, progress, session, upload, and coaching data is deleted within 30 calendar days. A narrow legal or security exception may apply; if it does, we will retain only what is necessary for only as long as required. See Delete your account.

Security

We use HTTPS, access controls, revocable sessions, server-side authorization, private media storage, restricted caching, input limits, and tested deployment procedures. No online service can guarantee absolute security. Please use a unique password and contact us promptly if you believe your account has been accessed without permission.

Your choices

You choose whether to select a video for on-device analysis or separately upload one for private review. You can clear saved on-device analyses from Analyze. You may update available profile details, download a copy of your account data, request support, ask privacy questions, or permanently delete your account from the Account tab. The same verified deletion flow is available through the web app. If you cannot sign in, use the contact below. Support may need to verify that you control the account, but will never ask you to send your password.

Age groups and limited teen accounts

People aged 13–17 can use lessons and save curriculum progress. Video upload and analysis, saved swing history, personalized swing images, coaching messages, personal profiles, and optional client diagnostics are unavailable to teen accounts. Adults 18 and older retain the adult features. Under-13 accounts are unavailable. If an age group was entered incorrectly, contact support; teen accounts cannot unlock adult access by changing a setting. Teen users can change their password, export permitted account data, or delete their account.

Changes to this policy

We will update the date at the top and provide an appropriate notice before a material change takes effect. A later release that adds coaching messages, payments, advertising, tracking, or additional teen capabilities will require an updated review and policy before that feature is enabled.
