Privacy Policy

Effective August 23, 2026

This policy covers sandboxsinkhole.com and the apps and games published by Sandbox Sinkhole LLC.

The short version

We don’t want your data. Our apps are built to work without accounts, ads, or tracking.

This website

sandboxsinkhole.com is a static site hosted on GitHub Pages. We don’t run analytics, set marketing cookies, or collect personal information here. GitHub, as the hosting provider, may log standard technical information (such as IP addresses) for security purposes — see GitHub’s privacy statement.

Our apps and games

• No accounts. Our apps don’t require you to sign up or sign in.
• No ads or trackers. We don’t include advertising or third-party tracking SDKs.
• Your data stays with you. Game progress and settings are stored locally — in your browser’s local storage for web games, or on your device for mobile apps.
• Multiplayer games (such as Countdown) transmit only what’s needed to run the session — game moves and a display name you choose. Game rooms live only in server memory and are deleted when the last player disconnects; we don’t store them. Our hosting provider (Google Cloud Run) keeps standard, short-lived technical request logs (such as IP address and timestamp) that never contain your name or what happened in the game.

If a future app needs to handle data differently, its own listing and support page will say so plainly, and this policy will be updated before release.

Purchases

Purchases in our mobile apps are processed by the App Store or Google Play. We receive no payment card details — payment is handled entirely by Apple or Google under their privacy policies.
