Tee to Green: Privacy
Last updated 4 November 2026.
Tee to Green is a golf yardage book. It has no advertising, no analytics and no tracking, and we don't sell anything about you. You don't need an account; the optional parts below (a shared card, a nickname, Sign in with Apple) are only used if you choose them.
What stays on your phone, or in your iCloud
- Your location. Used on the phone (and on your Apple Watch, if you use Tee to Green there) to measure distances on the hole and to list courses near you. It is never sent to us, with one exception: a pin marked on your Apple Watch by standing over the hole (below).
- Your rounds, scores, plans, markers, notes and bag. Kept on the phone and, if you use iCloud, in your private iCloud database, which only you can read. We can't see it, unless you choose to use the website (below). That includes the names you write in for the players on your card, and their scores.
- Your settings, including your name on cards and your handicap index.
Cards shared with other players
- A shared card is kept in iCloud: in the private iCloud database of the player who started it, shared through iCloud with the players on it. Everyone on the card sees the names, tees, handicaps and scores on it, and who wrote each score. We can't see it. A finished card is deleted from the organiser's iCloud 30 days after it's closed; every player keeps their own copy in their rounds.
- Inviting someone from your contacts uses the system's contact picker, so the app sees only the contact you pick. Their email address or phone number is looked up by iCloud to find them; it isn't sent to us or kept. The invite goes by a message you send.
- Your nickname, if you make it findable, is published in the app's public iCloud database with your home club, so other players can find you by it. Your name and contact details are never published. Turning it off removes it.
- Invites and requests to join a card are kept in the app's public iCloud database for a day, addressed to the player they're for, with the sender's nickname, the course and the date.
- Reports of a nickname are kept for us to read, with the nickname reported and the reason.
Pins shared with other players
- Marking a pin. If you say where the pin is on a green, or that it's still there, the app sends our course service the course, the hole, the spot on the green and the time. On the phone you tap the spot, and where you're standing isn't sent. On Apple Watch the spot is your position at that moment, so the watch asks before the flag shares any, and you can turn it off with Share my pins in its Settings.
- What other players see: the spot, when it was last seen, and how many other players have confirmed it. Never who.
- How long it's kept. One per green, with no history: the next pin marked there replaces it, and it's deleted 7 days after it was last seen. You can remove a pin you marked until someone else has confirmed it.
- Your name and account aren't on it. So a phone counts only once and can't mark too many, we keep a scrambled mark made from the App Attest key below: one per pin, deleted with the pin, and a count of the day's marks, deleted the next day. A phone's marks on two pins don't match. The service is hosted on Cloudflare, which sees the request's internet address as any web host does; we don't keep it.
Sign in with Apple
If you sign in with Apple, the app keeps the ID Apple gives us for you (not your name or email), in your settings and your iCloud. It's also how you sign in on the website. Delete it, with your nickname, invites, name on cards and handicap, in Settings, You, Delete my account.
The website (optional)
If you turn on the website in Settings, You, or sign in at t2g.club, your rounds and plans can be seen there. This is off until you sign in with Apple, and each device signs in for itself. While it's on, the app sends our server, for your account:
- Your rounds: the course, date, tees and format, and your own figures for each hole (par, strokes, putts, fairway, penalties, whether you picked up, and strokes gained by part of the game), with the handicap band you compare with, if you've chosen or set one. Not where you played each shot from, which clubs you used, your exact handicap, or the other players' names and scores.
- Your plans: the targets you've put on each hole.
- Your bag: each club's name and how far you hit it.
- The courses in your book: their ids and names.
- The ID Apple gives us for you, to know the account is yours. Not your name or email.
We use this only to show it back to you on the website and to bring plans you make there into the book. It's kept in a database hosted on Cloudflare until you delete it. Turning the website off in the app, or deleting your account, deletes the account and everything the app sent; your book and iCloud keep their copies.
What leaves the phone, and why
- To name your town ("Kew, VIC") above the courses near you, your position is looked up with Apple's geocoding service. Apple's privacy policy covers it.
- Your shots, your swing and Health, on Apple Watch. If you track shots, the watch reads its motion to notice a swing; the motion itself isn't kept or sent. Your shots stay with your round on your devices and in your private iCloud. A round runs as a golf workout, saved to Apple Health if you allow it; Tee to Green reads nothing back from it and sends none of it anywhere.
- The weather for the course you're playing comes from Apple Weather, looked up by the course's location, not yours.
- Courses. When you download or ask for a course, the app asks our course service for that course by its id. The service is hosted on Cloudflare, which sees the request's internet address as any web host does; we don't keep it.
- Proof it's the real app. So the course service only answers Tee to Green, the app makes a key for this install with Apple's App Attest, and the service keeps the key's public part with the date. It isn't tied to you or your account, and it's only used to check the app's requests.
- Course error reports. If you send one, it carries the course, its version, what you wrote and when. Nothing else, and only when you send it.
Your choices
- You can use the app without location: type a course's name instead.
- Removing the app removes what's on the phone. Your iCloud copy can be deleted in Settings, under your name, iCloud.
