GolfLM Privacy Policy

Effective November 4, 2026

GolfLM is an iPhone and iPad golf launch monitor app made by Robbie Elias. This page explains what information the app uses and what happens to it. "Your device" below means the iPhone or iPad you use GolfLM on.

In short: GolfLM does not collect or share your personal information. Everything the app records and measures stays on your device, unless you choose to send recordings to me with Send Recordings, described below. The app contacts other services in only three cases: if you turn on Use Local Conditions, your approximate location is sent to Apple Weather to get the local weather; the setup video in the tutorial is loaded from YouTube; and recordings you choose to send are uploaded to the app's storage in Apple's iCloud. There are no accounts, no ads, no analytics and no tracking.

Information the App Uses on Your Device

• Camera. GolfLM films the ball and club at 240 frames per second to measure each shot. The video is analyzed on your device. The captures of your most recent 20 swings are kept on the device for slow-motion replays. They are never uploaded unless you choose to send them to me (see Sending Recordings to the Developer). You can turn off saving captures, or delete them, in Settings → Data.
• Motion and air pressure. The app reads your device's tilt to understand how it is mounted. With Use Local Conditions on, it also reads the air pressure from your device's barometer, which affects how far the ball carries. These readings are used on the device only and are not stored with any personal information.
• Location (optional). If you turn on Use Local Conditions, in the first-run setup or in Settings → Conditions, and allow location access, GolfLM uses your approximate location, only while the app is open, to get the current air pressure, temperature and humidity from Apple Weather (Apple's WeatherKit service), which affect how far the ball carries. Your location is sent only to Apple for that request. It is never sent to me, it is not stored by the app (only the weather readings are kept), and it is not used for advertising or tracking. Weather requests are covered by Apple's Privacy Policy. Use Local Conditions is off unless you turn it on. You can turn it off in Settings → Conditions, or turn off location access for GolfLM in your device's Settings app, at any time.
• Shots and settings. Your shot and putt history, clubs and settings are stored in the app's own storage on your device. Shots and putts are kept for a year, and older ones are deleted automatically. If you back up your device to iCloud or a computer, this data may be included in that backup, which is handled by Apple under your backup settings.
• Free shot count. The number of free shots you have used today, and the date, are stored in your device's keychain, so that reinstalling the app doesn't reset them. They are only a number and a date, and they are not linked to you.
• Spoken results. Shot results are read aloud with your device's built-in voices, on the device.
• Sharing and saving. When you choose to share a picture or video of a shot, or save one to your photo library, it goes only where you send it, using your device's share sheet. GolfLM asks for permission only to add to your photo library, never to read it.

Sending Recordings to the Developer

If a reading looks wrong, you can send me your recent recordings so I can find out why, in Settings → Help → Send Recordings. Nothing is sent unless you tap Send there, and the app never sends recordings on its own.

• What is sent. Your most recent swing or putt captures (up to 10, as many as fit in about 18 MB): black-and-white overhead video of the mat, the ball and the club or putter. Also sent are what GolfLM measured from each one (such as the date and time, club, ball and club speeds, launch, direction and distances), what you chose under “What looks wrong?”, anything you typed in the optional note, and your device's model and iOS version and the app's version. Your name, Apple Account, location and contacts are not sent.
• Where it goes. The recordings are uploaded to GolfLM's storage in Apple's iCloud (CloudKit), which requires you to be signed in to iCloud on your device. They do not use your own iCloud storage. iCloud attaches an anonymous identifier that is specific to GolfLM and doesn't reveal your name or Apple Account. Only I can view them. This storage is provided by Apple and covered by Apple's Privacy Policy.
• The email. After the upload, GolfLM opens your email app with a message to me that names the recordings by a short code. If you send it, I receive your email address and anything you write, as with any email. You don't have to send the email: the recordings have already been uploaded.
• How they're used. I use them only to investigate and improve GolfLM's readings. They are never sold or shared, and I delete them once they're no longer needed for that. To have yours deleted sooner, email me the code from the message.

Setup Video and Links

• Setup video. The tutorial includes a video showing how to set up GolfLM, hosted on YouTube. When you open the tutorial, the video's preview picture is loaded from YouTube, and if you tap play, the video is played from YouTube's privacy-enhanced (no-cookie) player. As with any website, YouTube (Google) receives your device's IP address and basic device information to deliver the video. GolfLM sends YouTube nothing about you or your shots. This is covered by Google's Privacy Policy.
• Links. Links in the app, such as Find a tripod on Amazon, open in your web browser. Once you're on another website, its own privacy policy applies.

Subscriptions and Payments

GolfLM Pro subscriptions, including free trials, are sold and managed by Apple through the App Store. I never receive your payment details or your Apple Account information. The app checks whether you have an active subscription using Apple's StoreKit. Apple provides developers with sales reports that do not identify you. Purchases are covered by Apple's Privacy Policy. You can manage or cancel a subscription in GolfLM under Settings → Subscription, or in your Apple Account settings.

Sharing of Information

GolfLM does not sell, rent or share any information with anyone. Nothing about you or your shots leaves your device, except your approximate location, sent to Apple Weather when Use Local Conditions is on, the requests that load the setup video from YouTube, and recordings you choose to send to me with Send Recordings, all as described above, and anything you choose to share yourself. The app contains no third-party analytics, advertising or tracking services, and it does not track you across other apps or websites.

Deleting Your Data

You can delete your shots and recordings at any time in Settings → Data, or by deleting the app. Apart from recordings you choose to send me, nothing is sent to me, so there is no other copy for me to delete. To have recordings you sent deleted, email me the code from the message. The free shot count may remain in your device's keychain after the app is deleted.

Children’s Privacy

GolfLM is not directed at children under 13, and it does not knowingly collect personal information from anyone, including children.

Changes to This Privacy Policy

I may update this Privacy Policy from time to time. Any changes will be posted on this page, with a new effective date at the top. They take effect when they are posted.
