Privacy

Birdie Book is a golf score tracker. This page explains, in plain language, what we collect and why. We keep it minimal on purpose.

What we collect

• Your account: the name and email you sign up with.
• Your golf data: the rounds, scores, courses, players, handicap, and any stats you enter.
• Basic technical data: standard server logs needed to run and secure the service.

How we use it

To run the app: save your rounds, calculate your Birdie Book handicap estimate, show your stats, and let you share rounds with players you add. We do not sell your data, and we do not show third-party ads.

Where it lives

Your data is stored in a managed Postgres database (Supabase) and the app is hosted on Vercel. Access is protected by authentication and row-level database rules. Players in the same round and authorized event or course organizers can access the shared-round information needed to run that round. Accepted friends can see your career scores and analytics only when you explicitly enable that sharing in Settings. Public event boards intentionally show event names, player names, standings, and event results to anyone with the public link.

Vercel Web Analytics

Vercel, our hosting provider, uses Vercel Web Analytics to measure aggregate, cookie-less page views on our public pages and in the app shell. It does not use cross-site tracking, session recording, or advertising, and is not joined to a Birdie Book account or used to build a profile of an individual.

Optional AI phrasing

Coach's Corner findings are calculated by Birdie Book. If you deliberately choose Get the coach's take, Birdie Book sends a prompt-safe version of those deterministic findings and their structured numeric evidence to Google's Gemini API only to phrase the note. The request excludes your name, email, raw scorecard, internal source identifiers, and user-authored course and tee labels. The returned note is not saved in Birdie Book's database; your browser may cache it locally. You can use all deterministic Coach's Corner findings without requesting this optional AI phrasing.

Text messages (SMS)

If you give your mobile number to an event organizer when registering for an outing, Birdie Book may send you text messages about that specific event. These are operational messages only — registration confirmation, schedule or assignment reminders, an event-day check-in link, organizer updates, and final results. We never send marketing or promotional texts.

• We do not share or sell your mobile number. Mobile numbers and consent are never shared with third parties or affiliates for their own marketing purposes. They are shared only with the messaging provider that delivers the message on our behalf.
• Message frequency variesand depends on the events you register for. Expect roughly 1–5 messages per event you join.
• Message and data rates may apply.
• Reply STOP at any time to stop all messages, or HELP for help. STOP requests take effect immediately. Text START to resubscribe.
• Consent is limited to the event you registered for, and is never a condition of playing, registering, or using Birdie Book.

Your choices

• You can edit or delete your rounds at any time from within the app.
• You can enable or disable career score and analytics sharing with accepted friends in Settings.
• You can request deletion of your account and associated data by emailing us.

This is a plain-language summary for a small, early-stage app and will be expanded before any wider commercial launch.
