Privacy Policy — Escoba: Make 15 🃏

Last updated: 21 July 2026

Escoba: Make 15 does not collect, store, transmit, or share any personal information. It is a two-player (same-device) and solo educational card 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.

In-app purchase

The game is free and offers one optional, one-time in-app purchase (an unlock for the harder solo levels — Medium & Hard), placed behind a parental gate. The purchase is processed entirely by Apple's App Store or Google Play using your existing store account; the app itself receives and stores no payment or personal information — only an on-device note that the unlock is owned, so it keeps working offline. There are no ads, no subscriptions, and no consumable purchases.

Network & third parties

Gameplay makes no network connections and the app contains no third-party SDKs, advertising, trackers, or external links. All fonts and artwork are bundled, so the game works fully offline (for example, in airplane mode). The only network use is the optional purchase/restore described above, handled by the platform store when you choose to use it.

Data storage

Game state (the deck, the table, each player's captured cards and points, whose turn it is, your chosen language and settings) exists only in memory while you play and is discarded when the app closes. The single exception is a small on-device flag recording that the optional unlock was purchased; it contains no personal information and never leaves your device.

Children's privacy

Escoba is suitable for all ages. Because it collects no data and contains no ads, external links, or communication features — and any purchase requires passing a parental gate — it does not knowingly collect information from anyone, including children under 13.
