Usage statistics (Google Analytics for Firebase)
We use Google Analytics for Firebase to see how the game is played and where players get stuck, so we can tune the difficulty. The game sends these events: completing a stage and its number, using a hint or a pick on a stage, an ad being shown and its type, and finishing the whole journey. Firebase also records, by itself, sessions and their length, whether you come back to the game, your device type and OS, your approximate country, a random ID for this install of the app, and your advertising ID where your device allows it.
This data is not linked to your name, email or any account. We do not sell it and use it only for statistics. Google processes it on our behalf and keeps it for at most 14 months. In the EU and UK, statistics follow the choice you make in the consent screen, which you can change in the game's settings under «خيارات الإعلانات».
