Privacy
Stackport, a harbor puzzle by Nexus Gaming. Updated 2 November 2026.
Stackport measures how the game is played, never who plays it. There are no accounts, no ads and no in-app purchases.
What the game sends
- Anonymous gameplay events to the game's own server: a level started or ended, the result, how long it took and counters such as ships launched and boosters used, plus the screen size and the game version.
- Each event carries a random player id made on your device and a random id for the session. The server does not store your IP address, and the game never asks for your name or e-mail.
In the iOS app
The app sends the same anonymous gameplay events, and uses Google Analytics for Firebase to count players and the same kinds of events (level started, level ended and its result). Firebase keeps a random app instance id and reads the device model, iOS version and country. The app never reads the advertising identifier, does not track you across other apps or websites, and shows no ads. If the app hits an error, it sends the error message, without personal data, so we can fix it.
Your saved game
Progress, coins and harbor pieces are saved on your device only. Deleting the app, or clearing this site's data in your browser, removes them and the random ids.
Children
The game collects no personal data from anyone, children included.
