Stack Up: Blocks

Stack Up has no accounts, and never asks for your name, email, photos, camera, microphone, location, or contacts. Here is exactly what does and does not happen with data:

Game progress stays on your device. Your game in progress, high score, stats, Daily results and settings are stored locally and nowhere else. We do not run a server for them to go to.

Game Center is optional. If you are signed in to Apple's Game Center, your scores and achievements are posted to it under your Game Center name. That goes to Apple, under Apple's own privacy policy, and never to us. Everything else works without it.

Advertising. Stack Up is free and shows ads through Google AdMob: a full-screen ad between some games, and short videos you can choose to watch for a power-up or a revive. Where the law requires it, including the UK and the EU, Google's consent form asks for your choice the first time you open the game, and you can change it later under Settings › Privacy Choices. iOS also asks whether the game may track you; if you allow it, Google may use your device's advertising identifier to choose and measure ads, and if you do not, ads are shown without it. Either way, Google receives information such as your device type, IP address and how you interact with ads in order to serve them. See Google's privacy policy and how Google uses information from apps that use its services.

Remove Ads is an optional one-off purchase that stops the ads between games. Videos you choose to watch for an extra power-up stay available if you want them.

No analytics. Apart from what Google's ad delivery itself needs, there is no analytics or tracking SDK of any kind. The app does not send us anything.

Sharing your Daily result or final board uses the iPhone's own share sheet. You choose where it goes; nothing is sent to us.

Purchases are handled entirely by Apple's App Store. We never see your payment details.

Because we hold no accounts and no personal profiles, there is nothing on our side to export or delete. Deleting the app removes everything the game has stored on the device. To change what Google may use for ads, use Settings › Privacy Choices in the game, or iOS Settings › Privacy & Security › Tracking.
