Privacy Policy
Effective October 17, 2026
What changed on October 17, 2026:
- New Section 8 covers our website: the Google Analytics it uses (what it collects, its cookies, and how to opt out), the Master Caddies app link that QR codes open (what we record when it is opened, and the monthly counts we share with golf courses), and the Android waitlist on our download page.
- Section 3 now says Supabase and Vercel also store and host those website records, and points to Section 8 for Google Analytics. The former Sections 8 and 9 are now 9 and 10.
The previous version was effective October 15, 2026.
Lemmings, LLC (“we,” “us,” or “our”) operates the Master Caddies mobile application (the “App”), for iPhone, Android and Apple Watch. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App, and, in Section 8, when you use our website, followrover.com.
1. Information We Collect
- Account: The App creates an anonymous account the first time you open it. If you use Sign in with Apple, we receive Apple’s sign-in token and the name and email address Apple chooses to share with us.
- Player Profile: Your name, skill level, shot shape, ball flight, typical miss, scoring goal, handedness, handicap and its history, preferred approach distance, your bag (each club and its distances), your chosen caddie, and your App settings.
- Rounds: The course, tees and date; your scores and the pars for each hole; the round summary and analysis; and, for each question you ask during a round, the text of your question and the caddie’s answer, with the hole and the time.
- Shot Records: During a round, the App keeps a record of each shot you ask the caddie about: where you were standing (GPS coordinates and their accuracy), the hole and the yardage, the weather the App had at the time and any conditions you told the caddie, the kind of question you asked (not your words, which are kept with your round as described above), a summary of the caddie’s answer and the club it suggested, and, if you answer the short check-in after the shot, the club you hit and how the shot turned out. At the start of each round we also keep a copy of your handicap and your bag’s club distances with that round. Shot records are stored with your account, are visible only to you and to us, and are used to make the caddie’s advice work and to measure and improve it.
- Location: GPS coordinates, used in real time to calculate yardages to greens, hazards and approach distances, and to fetch the weather where you are. During a round the App also records your position about every 30 seconds and uploads that path to our servers with the round, together with phone battery readings and measurements of how long answers took, which we use to improve the App. There is currently no setting to turn this upload off. When you look for nearby courses, your location and the map area you are viewing are sent to our course database, which does not link them to your account.
- Voice: When you ask a question aloud — on your phone, in the post-round chat, or on your Apple Watch — the audio is recorded and sent to our speech-to-text provider. We do not keep the audio once the text comes back. The text of your question is kept with your round, as described above. On versions 1.0.92 and earlier, questions asked from the Apple Watch are sent to toolkit.rork.com for transcription; current versions don’t.
- Hands-free (optional): If you turn on Hands-free, the App keeps the microphone on during your round to listen for your caddie’s name. That listening happens on your phone. Nothing you say is recorded or sent until you say the wake phrase, and then only your question is sent, the same as when you tap the mic. We record when the wake phrase was detected (the time and a confidence score, never audio) with your round’s diagnostics. Hands-free is off until you turn it on, and you can turn it off at any time.
- Test versions (TestFlight): If you use a test version of the App from Apple’s TestFlight, it also uploads extra technical measurements with each round to help us fix problems before release: how well the App heard its wake phrase (detection scores, never audio), GPS accuracy and walking or riding speed for each hole, the type of network connection, the audio output in use (for example headphones or the phone speaker), and the timing of each recording. You can mark a moment with a flag and say a short note, which is kept as text with the round. You can turn this off in Profile. The App Store version of the App never collects these measurements.
- Scorecards: When you scan your scorecard to enter scores, the photo is sent to our AI provider (Anthropic) to read the scores and is not stored by us. Separately, and only if you choose to share it after a round, a photo of the course’s printed scorecard, and the yardage and par rows read from it, are sent to our course-intake service to improve our course data. We keep those as course reference data; they are sent with the course identifier only and are not linked to your account.
- Pin Sheets: If you scan the day’s pin sheet, the photo is sent, through our servers, to our pin-sheet reader (see Vercel in Section 3), which uses our AI provider (Anthropic) to read the pin positions. The photo is read and then discarded; we keep only a fingerprint of the image so the same sheet isn’t read twice, and location data is removed from the photo before it is sent. The pin positions you confirm are kept and shared anonymously with other golfers playing the same course that day. Your name, email and account identifier are not sent to the pin-sheet reader; it receives a coded reference instead, so it can limit how many scans one golfer makes in a day.
- Master Caddies on golf carts: Some golf carts run a Master Caddies screen. At the start of a round on a cart, each player may enter a mobile number and tick a box to have their scorecard and a link to the Master Caddies app texted to them after the round. A number is kept only if its box is ticked, together with a record of the exact consent wording and the time it was given. At present numbers are stored only on the cart and are erased when the next round starts; no messages are sent. When we begin sending, each opted-in number will receive one message per round; reply STOP to opt out or HELP for help; message and data rates may apply. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are not shared with any third parties, except the messaging provider that delivers the message.
- Feedback: The note you send, a contact (usually an email address) if you give one, and the question-and-answer log of the round it relates to.
- Course Requests: When you ask us to add a course: the course name, its city and state, your first name, an email address if you give one, and a random identifier the App generates. We email the request to our team and send you an acknowledgement at the address you gave.
- Course Search: The course names you type into search, sent to our course database. This is not linked to your account.
- Photos: With your permission, the App saves scorecard images to your device's photo library. We request add-only access — we cannot read, upload, or view any other photos in your library.
- App Usage: Which setup steps you completed or skipped, and how long they took.
- Diagnostic Data: Crash and error reports: your device model, operating system version, App version, and a trail of the App’s recent activity before the error. That trail can include the text of a question you asked. No account identifier is attached.
- Purchases: Which pass or subscription you bought and when, and the store’s transaction identifier. Purchases in the App are processed by Apple (App Store) or Google (Google Play). We never receive or store your card number, CVV, or full payment details.
- Apple Watch & Health: In current versions, the watch app sends nothing to the internet itself: it passes your recordings to your phone and plays back the caddie’s answer. (On versions 1.0.92 and earlier, see Voice, above.) It starts a workout session only so the answer keeps playing when you lower your wrist; the App does not read from or write to Apple Health.
The App contains no advertising, analytics, or tracking software, and does not send push notifications.
2. How We Use Your Information
We use the information we collect to:
- Provide personalized caddie briefings based on your skill level and playing style
- Calculate live GPS yardages and weather during your round
- Process voice and typed questions and deliver AI-generated caddie responses
- Generate post-round analysis and scoring insights
- Create shareable scorecards
- Find courses near you and keep our course data accurate
- Process payments and manage your subscription
- Improve the App’s accuracy, speed and reliability, and fix bugs
- Communicate with you about your account or the App
3. Third-Party Services
These are the outside services that receive your data, what each one is for, and what it receives. Some requests go straight from your device to the service; others are relayed through our own servers first. Either way, the service receives the content described.
- Supabase: Hosts our database and servers, in two separate projects. The first holds your account and everything tied to it — the profile, rounds, question-and-answer text, shot records (the shot positions, conditions, clubs and caddie recommendation saved during a round), round GPS paths, feedback, purchase records and App usage described in Section 1 — and also stores course requests, which are not linked to your account. The second holds our course database and receives, without any link to your account, your location when you look for nearby courses, the map area you are viewing, the course names you search for, and requests for course maps and recorded hole audio. It also holds the website records described in Section 8 (App link scans and the Android waitlist), separate from App accounts. When you turn on Hands-free, the App downloads its voice model from our servers; no personal data is sent to get it.
- Anthropic (Claude): Writes the caddie’s answers, reads scorecard and pin-sheet photos, and powers the post-round chat. Receives the text of your question with what the caddie needs to answer it — your name, handicap, club distances, shot shape and miss, the hole’s layout, and the weather — and, for those features, a scorecard photo or your round summary and chat. We do not attach your account identifier to these requests.
- OpenAI: Speech-to-text. Receives the audio recording of each question you ask aloud. In current versions that includes recordings made on your Apple Watch, which it reaches through your phone.
- Rork (toolkit.rork.com): Speech-to-text for the Apple Watch in older versions. On versions 1.0.92 and earlier, questions asked from the Apple Watch are sent to toolkit.rork.com for transcription; current versions don’t.
- Inworld AI: The caddie’s voice. Receives the text of the caddie’s answer, through our servers. No recording of your voice is sent.
- Google: Google Weather receives your precise location, through our servers, so Google sees our server rather than your phone. Google Maps (the map on Android) and Google’s 3D map tiles (the hole flyover) receive the map area being shown. A connection check sends an empty request to test whether your phone is online. For Android purchases, our server checks each purchase with Google Play, identifying the buyer by our account identifier. Our website (not the App) also uses Google Analytics, described in Section 8.
- Apple: Apple Maps (the map on iPhone) receives the map area being shown. Sign in with Apple, including revoking that sign-in when you delete your account. For App Store purchases, our server checks each purchase with Apple, and the purchase carries our account identifier so Apple’s receipt can be matched to your account.
- Cesium: Supplies the software for the 3D hole flyover. Receives your device’s network address and the page request only.
- Vercel: Hosts our course-intake service. Receives the scorecard photos you choose to submit, and the rows read from a scanned scorecard, with the course identifier only. They are not linked to your account. It also hosts our pin-sheet reader, which receives a pin-sheet photo you scan (TestFlight versions), sends it to Anthropic to read, and keeps only the pin positions it read, not the photo. The photo is not linked to your account. Vercel also hosts our website, including the App link and Android waitlist described in Section 8, and works out the approximate location of each App link scan from the network address.
- Sentry: Crash and error reporting. Receives the diagnostic data described in Section 1, which can include the text of a recent question. No account identifier is attached.
- Resend: Sends email. Receives a course request, to email it to our team, and your email address, to send you an acknowledgement.
- Stripe: Payment processing for Rover store purchases on our website, and for Master Caddies passes bought on our website before October 6, 2026. Passes can no longer be bought on our website; the App always pays through Apple or Google.
Each of these services processes data under its own privacy policy. We send the minimum each one needs to do its job.
4. Data Storage & Security
Your account data is stored in our database, hosted by Supabase. The App also keeps some data on your device so it works during a round without a connection.
Data sent between the App and our servers is encrypted in transit (TLS), and our database is encrypted at rest. However, no method of electronic storage or transmission is 100% secure.
5. Data Retention & Deletion
We keep your data until you delete your account; we do not delete it on a fixed schedule. Our database host keeps logs of requests to our servers for about 7 days.
To delete your account, open the App and go to Profile → Delete account. This deletes your profile, rounds, question-and-answer logs, shot records, round GPS paths, feedback, app usage records (such as which setup steps you completed), records of courses unlocked with a course code, records of your use of our servers, and your sign-in, and revokes Sign in with Apple. Records of your purchases are kept, with the link to your account removed. If your version of the App does not have Delete account yet, email us at info@followrover.com and we will delete your account for you.
Course requests and scorecard photos you submitted are kept as course data and are not linked to your account, so deleting your account does not remove them. To have one removed, contact us at info@followrover.com.
Crash reports are kept by Sentry, our crash-reporting service. They carry no account identifier, so deleting your account does not remove them, and one can contain the text of a question you asked. To ask us to remove crash reports that may contain your questions, contact us at info@followrover.com.
Voice recordings are not kept by us after they are transcribed; the text is kept with your round until you delete your account.
App link scans and the Android waitlist on our website are kept as described in Section 8.
6. Your Rights
Depending on your jurisdiction, you may have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Delete your data — which you can do yourself in the App, or by emailing us, as described in Section 5
- Opt out of data processing for marketing purposes
- Export your data in a portable format
To exercise any of the other rights, contact us at info@followrover.com.
7. Children's Privacy
The App is not intended for use by children under 13 years of age. We do not knowingly collect personal information from children under 13. If we learn we have collected such information, we will delete it promptly.
8. Our Website
This section covers our website, followrover.com. The App itself contains no analytics (see Section 1).
- Google Analytics: Our website uses Google Analytics, a Google service, to understand how visitors use it. It sets cookies in your browser (named “_ga” and “_ga_” followed by an ID, kept for up to 2 years) and receives the pages you view, how you arrived (for example from a search or another site), your browser and device type, your approximate location, which Google works out from your network address, and a few actions: tapping our App Store link and, in our store, adding items to the cart, starting checkout and completing an order (the order number, items and amounts — never your name, email or card details). Google processes this under its own privacy policy. To opt out, install Google’s Google Analytics opt-out browser add-on, or block or delete cookies in your browser settings, or use a content blocker. The site works the same either way.
- App link scans: The Master Caddies QR codes on golf carts and elsewhere open followrover.com/app, which sends you to the App Store or to our download page. Each time the link is opened we record the time, the type of device (iPhone, iPad, Android or computer), the approximate location (city, state or region, and country) that our website host, Vercel, works out from your network address, and the tags in the link that say where the code was placed (for example, the course and cart number). We do not store your network address or anything that identifies you or your phone, the link itself sets no cookies, and scans are not linked to an App account. (The download page it sends Android and computer visitors to uses Google Analytics, as described above.) We use these records to count scans, and we share monthly counts with the golf courses where the codes are placed. Courses see counts only, never individual scans.
- Android waitlist: On our download page you can ask to hear when the App is available on Google Play. We collect the email address you enter and, only if you choose, a US mobile number, with the date and the QR code (if any) that brought you to the page. A number is accepted only if you tick the box agreeing to texts; we keep the exact wording you agreed to and the time you agreed. We use your email and number only to tell you the Android App is available (one email, and up to 2 texts if you gave a number), and not for any other marketing. Reply STOP to any text to opt out or HELP for help; message and data rates may apply. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are not shared with any third parties, except the messaging provider that delivers the message. To leave the list at any time, email us at info@followrover.com. We delete the list within 90 days after we send the announcement.
- Where it is kept: Both are stored in our course database, hosted by Supabase (the second project described in Section 3), separate from App accounts, and are encrypted in transit and at rest.
- Spam protection: To stop abuse of the App link and the waitlist, we count how often each visitor uses them. For this we keep a scrambled code made from your network address, not the address itself. The code can’t be turned back into the address, changes every day, and is deleted within a day.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will post the updated policy on this page — the page the App opens — with a new effective date and a note of what changed.
