Privacy policy
The Number is an invite-only golf caddie app for iPhone and iPad, made by Karl Girthofer (“we”). This policy covers the app and this website's invite form.
The short version
- We keep your account, bag and rounds, including your position at each shot, to run the caddie and learn your game.
- Your shots and questions go to an AI model; your name, email and username do not.
- No ads, no tracking, no selling your data. Delete your account any time in the app.
What we store
- Account: your name, email address, and a username if you choose one.
- Profile: handicap, tees, clubs and distances, shot shape and usual miss, caddie settings, and notes about your game.
- Rounds: course, score, and each shot you ask about or log: your position, the lie, the caddie's call, whether you followed it, how it went and any note you add.
- Usage and technical records: how often you use the caddie and how each answer was made, for daily limits and to fix and improve the caddie.
What you type or say to the caddie goes to the AI model, but we do not save it.
Send Error Reports (Settings, off by default) sends a short note when something fails: what failed, app and iOS version, device model, round and hole; never your position or questions. Report a problem sends, once, the last 10 such notes, which the phone keeps even with that switch off, and gives you a code to send us; reports are kept 90 days.
If you request an invite
The Request an invite form asks for your name, email, phone type, which course to map next and, optionally, how you heard of The Number and a note. We use it only to send invites and to see which courses and phones people want.
Your course choice is also kept on its own, to count votes for the next course, under a one-way code made from your email address with a secret key, not the address itself. It stays after your request is deleted, until you ask for it to be removed or your account is deleted.
Your location
The app uses location only “While Using the App”, while a round is on screen, to measure distances. Your position is sent to our server when you ask the caddie, log or correct a shot, and, with “Have the call ready” on (off by default), when you stop at your ball. No background location, no continuous track.
Your voice
Talking to the caddie is optional. Apple's speech recognition turns your speech into text, on the device where possible, otherwise on Apple's servers. We get only the text, never audio.
Who else sees what
The app asks before anything goes to the AI model; choose “Not now” for distances only.
- Anthropic (Claude), the caddie's AI model, gets each shot situation, your clubs, game notes and recent shots, a random account ID and what you ask; not your name, email or username. Privacy policy.
- Deepgram, only if you turn on cloud spoken replies (off by default), gets the text of caddie replies to read aloud; not your voice, name, email or username. Privacy policy.
- Apple provides speech recognition, satellite maps and, if you share analytics with developers in iOS Settings, crash reports. Privacy policy.
- Mailgun (by Sinch) may deliver your invite email: it gets your name, email address and the invite, only to send it. Privacy policy.
- A weather service gets the course's location, not yours.
- A cloud provider in the United States hosts our server and data.
What we do not do
No ads, no tracking across apps or websites, no analytics or advertising software. We never sell your data or share it for marketing. This website sets no cookies.
Keeping and deleting your data
Your data is kept while your account exists. Technical records are deleted after 90 days, unless kept to look into a problem (then deleted with your account). Invite requests that don't lead to an invite are deleted about 12 months after they are sent.
To delete your account and its data, go to Settings, Account, Delete my account, or email hello@thenumbergolf.com (done within 90 days). Our admin log keeps your name and email with any admin action on your account, such as your invite, even after deletion. To see or correct your data, email the same address.
Children
The app is not meant for children under 13, and we do not knowingly collect their data.
Changes
If this policy changes in a way that matters, we will post the new version here with a new date.
