Sky Stacker — Privacy Policy

Effective date: October 5, 2026

Summary: Sky Stacker does not collect, store on any server, sell, or share your personal data. There is no account, no analytics, no advertising, and no tracking.

Information stored on your device

Your best score and your language preference (English or Chinese) are saved locally on your device only. They are never uploaded. Deleting the app removes them.

Voice call-outs

The game speaks short phrases such as "Game over! 41 floors." Most phrases are bundled with the app. When a phrase is not bundled, the app sends only that fixed game phrase and the language code to our text-to-speech service to generate audio. No identifiers, device information, or personal data are included, and the request is not linked to you. If you are offline, the game simply plays without voice.

Third parties

We do not use third-party analytics, advertising, or tracking SDKs. Standard network logs of the text-to-speech service provider may briefly record technical request data (such as IP address) for security and operation, as with any internet request; we do not use this to identify you.

Children

Sky Stacker is suitable for all ages and does not knowingly collect any personal information from children or anyone else.

Changes

If this policy changes, we will update this page and the effective date above.
