⚾ TeeBall Playbook

Privacy Policy

Effective date: September 21, 2026

This Privacy Policy explains how TeeBall Playbook ("the app," "we," "us"), provided by Aaron Kightlinger, handles information. TeeBall Playbook is a practice-planning tool for volunteer coaches. You do not create an account to use it, and it is built to keep your information on your device wherever possible.

This is a plain-language summary and the policy itself. It is a good-faith draft; please have it reviewed for your specific situation before publishing.

The short version

No account, no login. The app works without you signing up.
Most of your data never leaves your phone — your practice plans, schedule, your team roster, your notes, the drill library, your settings, and any photos you add are stored locally on your device.
We only send data off your device when you use an AI feature ("Suggest a Plan" or "Analyze my plan"), and even then we send no name, email, or account — just an anonymous device code and the practice details needed to build the suggestion.
No ads. No third-party advertising or tracking.

Information stored on your device

The following stay on your device and are not uploaded to us:

Practice plans you create or save.
Your practice schedule (the dates and times you plan practices).
Your team roster — the player names and jersey numbers you type in.
Notes you write about how a practice went.
The drill library and your view/browse activity.
App settings and preferences.
Any drill photos you choose to add (kept in the app's local storage).

Deleting the app removes this local data.

Information sent when you use AI features

TeeBall Playbook offers optional AI helpers — "Suggest a Plan" and "Analyze my plan." When (and only when) you tap one, the app sends the following to our server (hosted on Supabase) and to our AI provider (Anthropic, which runs the Claude model that generates the response):

A random device identifier — a randomly generated code stored on your device. It is not your name, email, phone number, or Apple ID, and it is used only to power the feature and to enforce a fair daily usage limit.
The practice details you're working with: the age band, practice length, how many kids you expect, focus areas, the list of drills (the catalog), and — for "Analyze my plan" — the plan you're analyzing.

Your roster and your notes are never part of this. Player names, jersey numbers and practice notes stay on your device even when you use an AI feature. The only thing sent about your team is how many kids you expect — a head count, because a drill for six children is not a drill for sixteen. It is a number on its own: it names nobody, it is not linked to you, and it is not kept once your plan comes back.

We use this information solely to generate your plan or analysis and to rate-limit requests (to prevent abuse of the service). We do not use it to identify you or to build a profile.

The random device identifier and the date are stored on our server to count daily usage; these counters are short-lived and are not linked to your identity.

Purchases

If you subscribe, the purchase is handled by Apple. We use RevenueCat to check whether your subscription is active. RevenueCat receives the purchase event and an anonymous identifier for your app install. Neither we nor RevenueCat receive your payment details — Apple handles those.

Notifications

If you allow notifications, the app uses local notifications on your device (for the practice timer). No notification data is sent to us or any server.

Children's privacy

TeeBall Playbook is a tool for coaches (adults). It is not directed to children, and children do not use it.

The app does let a coach keep a team roster — the player names and jersey numbers the coach types in — and write notes about a practice. That information is stored only on the coach's own device. It is never uploaded to us, never sent to our AI provider, never shared with anyone, and it is removed when the app is deleted. There is no account it could be attached to.

We collect none of it ourselves and we never see it. We suggest coaches enter no more than they need — a first name or a nickname is enough for a roster.

This website

Everything above is about the app. The website (teeballplaybook.com) is separate, and it is worth being explicit about, because this policy previously said nothing about it at all.

No accounts, no cookies, no analytics. We do not track you here, and we cannot tell one visitor from another.
Hosting. The site is served by Cloudflare Pages, which, like any web host, processes your IP address in order to deliver the page.
Fonts. The pages load two typefaces from Google Fonts. That request means Google receives your IP address. We get nothing from it and we do not use it for anything — but it is a third party, so you should know it is there.

How we share information

We do not sell your information. The limited data described above is shared only with the service providers that make the AI features work (Supabase, which hosts our server, and Anthropic, which runs the Claude model), and only for those purposes. We may disclose information if required by law.

Your choices

You can use the entire core app (build and run practices) without ever using the AI features, meaning no data leaves your device.
Deleting the app removes locally stored data.
You can manage notification permission in your device settings.

Changes to this policy

We may update this policy; we'll revise the "Effective date" above and, for significant changes, note them in the app or store listing.
