StackStack Privacy Policy

Last updated: March 2026

Information We Collect

StackStack collects minimal data to provide game functionality:

• Device ID: A randomly generated UUID stored locally on your device for leaderboard identification. This is not linked to your personal identity.
• Nickname: A player-chosen or auto-generated display name for the leaderboard.
• Game Scores: Floor count, score, and combo data submitted to our leaderboard service.
• Country Code: Estimated from your device's timezone setting (not IP address) for displaying country flags on the leaderboard.

Third-Party Services

• Supabase: Hosts our leaderboard database. Supabase Privacy Policy
• Twemoji: Emoji images from Twitter's open-source library, loaded from CDN or bundled locally.

Data Storage

Game progress (upgrades, coins, settings) is stored locally on your device using localStorage. This data is not transmitted to any server except leaderboard scores.

Children's Privacy

StackStack is NOT directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information through this app, please contact us immediately at stackstack.game@gmail.com and we will promptly delete such information.

Data Deletion

You may delete your local data at any time by clearing your browser or app data.

To request deletion of your leaderboard data stored on our servers, email stackstack.game@gmail.com with your in-game nickname or device information. We will process your request within 72 hours.
