Privacy Policy

Effective: October 11, 2026

This policy explains how JapanMarketing LLC ("we") handles information in the game "Starship Alcubierre" (web, iOS and YouTube Playables versions, "the Game").

Data stored on your device

Your pilot level, experience, upgraded technologies, secured sectors, scores and sound/language settings are stored on your device (browser or app). In the YouTube Playables version the same data is stored with YouTube's game save feature. We do not receive this data.

Error reports

To find and fix bugs, the web and iOS versions send error details (the error, where it happened, device and OS, browser type and game version) to the error-monitoring service Sentry (Functional Software, Inc.) when an error occurs. We do not send your name, email address, identifiers based on your IP address, or your save data, and we do not use these reports for advertising, tracking or behavioral analysis. The YouTube Playables version does not send error reports.

Accounts, ads and purchases

The Game has no accounts, no ads and no in-app purchases.

Web delivery

The web version uses Cloudflare for delivery and security, which may process IP addresses and request information for those purposes.

Contacting us

If you email us, we use your address and message only to reply. We never sell personal information.

Changes

We will announce changes to this policy on this page.
