Manuel Burger
Gartenstraße 1A
98553 Schleusingen, Germany

Phone: +4915567138522

The contact details correspond to the information provided in the Legal Notice.

2. Hosting (Static Web App)

This website is operated as a static web app. The frontend is currently delivered via GitHub Pages (GitHub, Inc.). Technically required connection data is processed to deliver the website.

3. Server Log Files

The hosting provider automatically collects server log files on every request (e.g., IP address, browser type/version, date/time of request, referrer, requested resource). Processing is carried out to ensure security, stability, and protection against misuse/DDoS attacks.

4. Local Storage in the Browser (Local Storage / IndexedDB)

Silent Sand stores settings, garden saves, reminder status, streak information, feedback invitation cooldowns, and local game states in your device browser (Local Storage and IndexedDB). This data is generally not transmitted to our server and remains local on your device unless you use a network feature you actively trigger.

5. Google and Firebase Services

Google/Firebase services, including Cloud Functions, are used for features such as leaderboards and shared gardens. Players use a browser-local guest identity; no account or profile sign-in is offered.

If data is transferred to third countries (especially the USA), this is done on the basis of appropriate safeguards, in particular standard contractual clauses (SCCs) pursuant to Art. 46 GDPR.

6. Payment Processing (Stripe)

Stripe may be used for payment processing. The provider in the EEA is Stripe Payments Europe Ltd., 1 Grand Canal Street Lower, Grand Canal Dock, Dublin, Ireland. The legal basis is Art. 6(1)(b) GDPR (performance of a contract or steps prior to entering into a contract).

Payment data, in particular credit card data, is processed directly by Stripe and is not stored on our server. Stripe may use technically necessary cookies for fraud prevention and session management.

7. Other Recipients / Third-Party Providers

Additional service providers may be integrated for usage analysis and feature delivery, in particular: Google Analytics/Google Tag (audience measurement) and Cloudinary (uploading shared screenshots). Processing is carried out only to the extent required in each case.

Optional Feedback

When you press Send feedback, your ratings and optional comment are saved in the website operator's Google Cloud Firestore database for private review. No name or email address is required. Please avoid including personal information in your comment. The feedback service also records the submission time, browser user agent, request origin, and a hashed IP address for operation and abuse prevention. Feedback is not published to other visitors.

8. Cookies

This website uses technically necessary browser storage mechanisms and integrated third parties may set cookies. This includes, in particular, cookies for security, session management, and fraud prevention (e.g., with Stripe), and where applicable for analytics or authentication functions.

9. Legal Bases

Personal data is processed depending on purpose on the basis of Art. 6(1)(b) GDPR (performance of a contract), Art. 6(1)(f) GDPR (legitimate interest in secure and stable operation), and where required, on the basis of your consent (Art. 6(1)(a) GDPR).
