Wiener Run Privacy

Updated 11 November 2026.

The Wiener Run app collects no personal data. It has no game accounts, advertising, analytics or tracking. The game and its audio are bundled and work offline.

Crash reports

If the game runs into an error it can’t recover from, it sends a short crash report to our server, so we can fix it. A report holds the error and where in the game’s code it happened, the game’s version and build, whether it was the app or the browser game, the operating system in general terms (for example, “iOS 18” or “Chrome on Mac”) and which level was being played. It holds no name, account, device identifier, IP address or game progress, and it isn’t used to track you. Reports are kept for 90 days. Without a connection, a report waits on your device and is sent the next time the game starts.

Your progress in the app

The iOS app stores game progress on your device and uses Apple’s iCloud key-value storage to merge progress across your devices using the same Apple Account, when iCloud is available. Only game progress is sent to iCloud: cleared stops, souvenirs, best times, travel scenes, map position, chosen world, difficulty, lives, the dog you picked and save time. We cannot access this data. Sound, music and vibration choices stay on your device. Local preferences may be included in device backups. Deleting the app removes local data; progress already synchronized to iCloud can return after reinstalling. Choosing New game replaces your progress, on every device using the same Apple Account. iCloud synchronization may be delayed or unavailable offline.

The browser game

The browser game stores progress and settings in your browser. Your browser can remove them. The website host receives the requests needed to deliver the game; apart from crash reports, the game sends no gameplay or personal information.

The trailer

The website’s trailer comes from YouTube only when you choose to watch it. On a computer it plays on the page from YouTube’s privacy-enhanced player (youtube-nocookie.com); on a phone or tablet the link opens YouTube. Either way, YouTube then receives what it needs to play the video, under Google’s privacy policy. Nothing from YouTube loads until you press play.

Controllers and vibration

Optional controller input and vibration are used only while playing. They are not recorded or sent anywhere. There are no permission prompts.

The holiday add-on

The app offers one optional purchase, the Home for the Holidays add-on. Apple handles the purchase, its payment and its restoring; we receive no payment details or Apple Account information. To open its worlds, the app asks Apple’s purchase system on your device whether the add-on is owned; nothing about it is sent to us. The browser game sells nothing.

Copies of the game

The game runs only at playwienerrun.com and in our own app. If a copy of it is found running on another website or inside another app, it points to the real game and tells our server once where it was found (that site’s address or that app’s name) and which version of the game it is. It sends nothing about the player.
