Stackt is a puzzle game. It does not require an account, and it does not collect your name, email, or any profile information. This page explains the only two places data leaves your device: showing ads, and processing a purchase.
The free version of Stackt shows ads between rounds, served by Google AdMob. Stackt does not request permission to track you across other apps or websites, and does not link any identifier to your identity — AdMob serves non-personalized, contextual ads only.
AdMob may still process basic technical signals (like approximate location from IP, and ad impression/click counts) to deliver and measure ads and prevent fraud. This is handled under Google's Privacy Policy.
Purchasing Remove Ads from the in-game Shop turns advertising off entirely — no further ad requests are made.
The Remove Ads purchase is processed entirely by Apple through StoreKit. Stackt never sees or stores your payment details — Apple handles billing, receipts, and purchase restoration under Apple's Privacy Policy.
Your round progress, high scores, streaks, and sound/haptics settings are stored locally with UserDefaults and SwiftData. None of it is transmitted anywhere, uninstalling the app deletes it, and Stackt has no server of its own to send it to.
After your first win, Stackt may ask permission to send a daily reminder to keep your streak going. This is scheduled entirely on your device — no data is sent anywhere to make it happen, and you can turn it off anytime in iOS Settings → Stackt → Notifications.
Stackt is listed under the Games category and is not directed at children under 13. We don't knowingly collect data from children. Advertising on the app is served under Google AdMob's standard (non-child-directed) treatment.
