Privacy Policy — Math Duel 🍓 vs 🫐

Last updated: 12 June 2026

Math Duel does not collect, store, transmit, or share any personal information. It is a two-player, same-device math game that runs entirely offline on your device.

Information we collect

None. The app has no accounts, no sign-in, and no analytics. It does not request your name, email, contacts, location, photos, identifiers, or any other personal data.

Network & third parties

The app makes no network connections at runtime and contains no third-party SDKs, advertising, trackers, or external links. All fonts and assets are bundled in the app, so it works fully offline (for example, in airplane mode).

Data storage

Game state (scores, the current round, your chosen language and settings) exists only in memory while you play and is discarded when the app closes. Nothing is written to disk, cookies, or any cloud service.

Children's privacy

Math Duel is suitable for children. Because it collects no data and contains no ads, purchases, external links, or communication features, it does not knowingly collect information from anyone, including children under 13.
