Last updated September 30, 2026. This policy covers the Stackdle iPhone and iPad app published by Isaac Audet.
The app stores game progress, preferences, and saved results on your device. No account or sign-in is required.
Daily scores, piece placements, and tower replays are sent to our game server for score verification and community results. An app-generated identifier and server cookie can recognize the same installation so daily attempts and your own results remain consistent. Gameplay diagnostics, such as which pieces held or fell, are also sent to help us improve the physics. These diagnostic batches do not include your name, account, or complete saved tower.
Our hosting and database providers process requests needed to run these features. Connection information, such as IP addresses, may be processed for hosting, security, and abuse prevention. Stored game results support daily comparisons and replays.
Firebase Analytics is optional and starts only after you choose to allow analytics. It collects app usage, sessions, gameplay events, app and device information, an app-instance identifier, and approximate location derived from connection information to help improve the game. We do not send your name, email, saved replays, or advertising identifier to Analytics. Advertising consent is denied and IDFV collection is disabled. You can change your analytics choice in the app. There are no advertisements or cross-app tracking. Microsoft Clarity and web analytics scripts do not run in the iOS app.
Capgo checks for and delivers compatible game updates. It processes an installation identifier, app and bundle versions, device platform, and connection information to deliver updates and recover from failed startup. Optional updater statistics are disabled. Native app changes are delivered through the App Store.
Sharing is optional. The iOS share sheet sends only the result link, text, image, or GIF you choose to the app or recipient you select. Shared links can expose the encoded result or a public tower replay to anyone with the link.
You can play without sharing. Removing the app removes its local data. Server records are separate. Contact us about privacy questions or deletion requests; for Stackdle, include the daily date and a result link if available so we can identify the relevant record.
