Privacy Policy

Champ Calc does not collect, store, or transmit any personal data. There is no account, no sign-up, and no user data of any kind sent off your device.

What the app does

Champ Calc reads publicly available Formula 1 standings and calendar data from a static JSON file hosted on GitHub (raw.githubusercontent.com/arthurkahwa/champcalc) and computes championship-contention math from it, entirely on your device. These requests carry no account identifiers, device identifiers, or user content — they're the same request anyone would get fetching a public web page.

What stays on your device

• Preferences (e.g. your selected driver/team) — stored locally via iOS's standard UserDefaults, never transmitted anywhere.
• A local cache of the season data JSON, stored in the app's Caches directory, so the app still works offline or if the data source is briefly unavailable. Also never transmitted anywhere.

Neither of these ever leaves your device. Deleting the app deletes them.

What we don't do

• No analytics, telemetry, or crash reporting SDKs.
• No advertising or ad SDKs.
• No third-party SDKs of any kind.
• No push notifications.
• No accounts, sign-in, or user-generated content.
• No tracking, and nothing is shared with or sold to anyone.

Children's privacy

Champ Calc does not knowingly collect any data from anyone, including children, because it does not collect data at all.

Changes to this policy

If Champ Calc ever starts collecting data (for example, if push notifications are added in a future version), this page will be updated first, and the change will be reflected in the app's App Store Connect privacy declarations.
