Privacy Policy — zynthor.games

Effective date: June 2026

1. Introduction

zynthor.games ("we", "us", "our") operates the Rock Slots social casino website at zynthor.games. This Privacy Policy describes our data handling practices. We have engineered our service to be privacy-first: we collect no personal data and operate no servers that process user information.

2. Data We Collect

We do not collect, store, or transmit any personal information. All game state, including your virtual Amp Credit balance, stage name, achievement progress, and bonus timestamps, is stored exclusively in your browser's localStorage on your own device.

3. localStorage Usage

We use browser localStorage under the key sc_zynthor to save:

• Your chosen stage name (player name)
• Your current Amp Credit balance
• Your player level and experience points
• Daily Setlist streak and claim timestamps
• Backstage Pass and Amp Wheel cooldown timestamps
• Achievement and badge unlock status and progress
• Tournament rank assignment (sc_zynthor.tournRank)
• Age gate confirmation (sc_age_ok)
• Cookie consent flag (sc_cookies_ok)

This data is stored solely on your device and is never transmitted to any server.

4. Cookies

We use no tracking cookies, session cookies, or advertising cookies. The only browser storage we use is localStorage as described in Section 3. Our cookie consent banner informs you of this localStorage usage.

5. Analytics and Tracking

We do not use any analytics platforms, tracking pixels, or behavioral monitoring tools. We have no visibility into how players use the site.

6. Advertising

We display no advertisements and participate in no advertising networks. No data is shared with advertisers.

7. Third-Party Services

We load fonts from Google Fonts (fonts.googleapis.com). Google may log your IP address when serving font files, subject to Google's own Privacy Policy (policies.google.com/privacy). No other third-party services, scripts, or APIs are loaded.

8. Age and Children's Privacy

Our service requires users to be 21 years or older. We do not knowingly allow access by minors. We collect no information that would identify a user's age, but our age gate requires self-certification.

9. Data Retention and Deletion

All data resides in your browser's localStorage. It persists until you clear browser site data or manually remove it. To delete all your data: open browser DevTools → Application → Local Storage → delete the sc_zynthor and sc_cookies_ok and sc_age_ok keys. There is no server-side data to delete.

10. Your Rights

Since all data is local to your browser, you have complete control at all times. No account deletion request is necessary. No data portability request is possible since we hold no data.
