Your information
Privacy Policy
Effective and last updated: October 29, 2026
Dirck Golf is the app from Dirck Golf School, operated by Benjamin Dirck. It provides golf curriculum, progress tracking, on-device swing analysis, and optional private swing-review tools. This policy explains the information the service uses and the choices available to you.
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
- create and secure your account, authenticate sign-ins, and enforce account roles;
- save and synchronize your curriculum progress;
- provide private swing upload and review features you choose to use;
- answer support, privacy, and deletion requests;
- prevent fraud, abuse, unauthorized access, and technical failures; and
- meet legal obligations and enforce the Terms of Use.
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.
- Cloudflare provides application hosting, network protection, serverless processing, database storage, and private object storage.
- Apple and Google may process app-download, device, purchase-account, diagnostics, and store information under their own policies when you use their platforms. The initial app does not sell digital access.
- External destinations such as YouTube and Amazon receive ordinary browser or app information when their pages or externally hosted images are requested. Amazon product images may load when you view the Gear Guide. Lesson videos and product links open external services whose own terms and privacy policies apply. Coach resource links may also open Topgolf SharePoint, which can require your Topgolf work account. Gear links may be affiliate links; the app discloses that we may earn a commission. Dirck Golf School does not download or rehost YouTube videos. The current app does not connect to Spotify or Apple Music.
- Authorities or safety recipients may receive limited information if disclosure is reasonably necessary to comply with law, protect rights and safety, or investigate misuse.
Retention and deletion
| Information | Normal retention |
|---|---|
| Active account, profile, and progress | While 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 video | Up to 90 days after upload. |
| Completed original swing video | Up to 30 days after analysis delivery. |
| Coach-analysis video | Up to 180 days after delivery. |
| Operational logs | Up to 30 days. |
| Security and abuse-prevention records | Up to 90 days, unless a documented incident requires longer preservation. |
| Support requests | Up to 24 months after closure, unless an active dispute or legal obligation requires longer retention. |
| Approved encrypted backups | Rolling 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.
