CourtClock

Privacy Policy

Effective date: 25 August 2026

The short version

No accounts. There is nothing to sign up for and no password to forget.
Your teams, players and game records never leave your device. They are saved in the app's own local storage, and we have no way to read them.
No ads, no third-party trackers, and we never sell or share your data.
The app does send a small anonymous count so we can tell how many devices use it. It contains no names and nothing from your roster.

CourtClock is a live basketball substitution and playing-time tracker, made by Mihee Youn. It is designed for the parent or coach who has the substitution job this week — which is why it asks for nothing and works without a connection. This page explains exactly what it stores and what it sends.

1. What stays on your device

Everything you type or track stays in the app's local storage on your phone or computer:

Team names, player names and player numbers
Who is on court, who is on the bench, and the running playing time for each player
The period, the game clock, and the game format you chose
Your light/dark theme preference

None of this is uploaded. There is no account, no sync and no server copy — so we cannot see it, cannot recover it for you, and cannot hand it to anyone else. If you use the app on two devices, they do not share data.

2. What the app sends

One thing only: an anonymous usage ping, sent to our own server when the app is opened.

What is in the ping	That the app was opened, which page it was, the referring page and any link parameters (when the app is opened from a link), and a random device ID.
The random device ID	A UUID generated on this install and kept in local storage under `courtclock-device-id`. It is not your name, your email, your phone number or your Apple/Google account — there are none of those in this app. It exists only so a returning device is not counted twice.
What is never in it	Nothing from your roster or your game. No team names, no player names, no numbers, no playing times, no scores. The code that sends the ping has no access to that data.
Why	To know roughly how many people use CourtClock. That is the only reason.
Where it goes	Our own infrastructure, over HTTPS. It is not sent to an advertising network, an analytics vendor or a data broker.

We do not store your IP address against the ping. The ping is not used for advertising, is never combined with data from other apps or websites, and is never used to identify you.

Being straight about the limits: there is currently no switch to turn this ping off. If that matters to you, section 4 explains how to clear the device ID, and you can stop it entirely by not using the app.

3. Fonts

The app's typefaces are loaded from Google Fonts. As with any web font, Google's servers see the request and therefore your IP address. No CourtClock data is included in that request. If you are offline, the app still works and simply falls back to your device's own fonts.

4. Deleting your data

Because there is no account, deletion is entirely in your hands:

In the app: a team can be deleted from the team menu (tap the team name at the top → ⋯ → delete).
Everything at once: deleting the app from your device removes all of it — teams, rosters, game state and the random device ID. On the web, clearing site data for this site does the same.
Once the device ID is gone, a new one is generated the next time you open the app, and the two cannot be connected.

We want to be honest rather than promise something we cannot do: the anonymous pings already sent carry only that random ID, and we hold nothing that links them to you — no name, no email, no account, no IP. Once the app is removed we have no way to work out which anonymous rows were yours. That is a consequence of collecting no identity in the first place, not an oversight.

5. What we never do

We do not show ads or use advertising SDKs.
We do not sell, rent or share your data with anyone.
We do not build profiles, and we do not track you across other apps or websites.
We do not ask for your location, contacts, photos, microphone or camera.

6. Children

CourtClock is a tool for the adult running substitutions. It has no accounts, no messaging, no social features and no ads, and it does not knowingly collect personal information from anyone, including children. Player names typed into a roster stay on the device that typed them.

7. Changes

If this policy changes, the effective date above changes and the new version is posted here. If we ever add something that sends more than the anonymous ping described in section 2, we will describe it here first.
