Last updated: August 2026 · Applies to Sylvania 1.0.0
The short version: Sylvania is a single-player puzzle game. Your scores, coins, settings and saved game are stored on your device only. There is no Sylvania account and no analytics that watches how you play.
Everything you build up in Sylvania — your best score, your coin balance, the power-ups you have unlocked, your sound and haptics settings, and the game you have in progress — lives in the app's private storage on your phone, which other apps cannot read. Deleting the app deletes all of it; there is no server-side copy of your progress.
If you use your operating system's device backup (Android backup / iCloud device backup), the app's files may be included. That backup is made and encrypted by your OS under your Google or Apple account settings — Sylvania neither adds to it nor reads from it.
Coin packs and the daily ration are purchased through Apple's App Store or Google Play — Sylvania never sees your card or payment details. To confirm a purchase, the store's purchase receipt/token and an anonymous in-app player identifier are sent to Sylvania's own server for validation before coins are granted. Those messages contain the store token and the anonymous player id and nothing else — no name, email, contacts, or location.
The optional "watch for coins" reward is served by Google AdMob (the Google Mobile Ads SDK). To show ads and prevent ad fraud, Google's SDK processes device and diagnostic identifiers under Google's policies. Sylvania does not show an App Tracking Transparency prompt and does not track you across other companies' apps and websites; where you have not consented, ads are served non-personalized. You only ever see an ad if you choose to tap the reward button.
| Internet | Used only by the in-app purchase validation and the optional rewarded ad described above. The game itself plays fully offline; network is used only for those two features. |
Sylvania requests no camera, photos, microphone, location, contacts, or device-storage permissions.
Sylvania is a general-audience puzzle game. It collects no personal information from anyone, including children. (If your build serves ads, they are non-personalized absent consent, as described above.)
If a future version changes any of the above, this policy will be updated before that version ships.
