3. Services
Swiss Karaoke provides a full-service karaoke offering. Depending on the booking, this includes delivery, set-up and tear-down, professional sound and lighting equipment, a host/karaoke jockey (KJ) and access to a song catalogue of more than 120,000 titles. Song selection and cueing during the event are handled by the KJ.
4. Prices and VAT
The prices stated in the order confirmation apply. The base price for the full service starts at CHF 1,200. All prices include statutory value added tax.
5. Travel
Within a radius of 100 km around Zurich HB station, travel is included in the price. For greater distances, a travel fee of CHF 1.50 per kilometre is charged; this rate covers the entire round trip.
6. Deposit and payment terms
Upon placing the order, a deposit of 30% of the agreed price is due. For the remaining amount: business customers receive an invoice after the event, payable within 30 days. Private customers pay the remaining amount so that the full price is settled no later than one day before the event. Payment is made by invoice or TWINT. In the event of late payment, default interest and reminder fees may be charged.
7. Cancellation by the customer
Cancellations must be made in writing. The following cancellation fees apply, calculated on the agreed price: up to 30 days before the event free of charge; 29 to 14 days before 25%; 13 to 7 days before 50%; less than 7 days before or no-show 100%. Rescheduling is possible subject to availability and by agreement; otherwise the above cancellation fees apply.
8. Customer obligations
At the venue, the customer provides free of charge a standard 230 V power connection, a level, weather-protected area of at least approx. 3×3 m and access for set-up and tear-down. The customer is responsible for any official permits, compliance with noise protection regulations and the domestic authority at the venue.
9. Equipment and operation
The professional equipment used is operated exclusively by Swiss Karaoke staff and is not left unattended or rented out. The customer is liable for damage to the equipment caused intentionally or through gross negligence by the customer or their guests.
10. Liability and force majeure
Swiss Karaoke is liable for damages only in cases of intent or gross negligence; liability for slight negligence as well as for indirect and consequential damages is excluded to the extent permitted by law. If the service cannot be provided due to force majeure (e.g. severe weather, official orders, illness), an alternative date will be arranged where possible; further claims are excluded.
11. Data protection
Swiss Karaoke processes personal data exclusively within the framework of applicable data protection legislation. Details can be found in the privacy policy on the respective website.

This privacy policy explains how personal data is processed when you visit the websites of Subwork Romey (swisskaraoke.ch, .de, .com, .fr, .it). The Swiss Data Protection Act (FADP) and, where applicable, the EU General Data Protection Regulation (GDPR) apply.
The German-language version of this privacy policy is authoritative. Translations are provided for ease of understanding only; in the event of discrepancies, the German version prevails.
1. Controller
The controller responsible for data processing is: Subwork Romey, Schinebuelstrasse 30f, 5413 Birmenstorf, Switzerland. Contact for data protection matters: h.romey@subwork.ch.
2. Processing when visiting the website
When you access the website, the hosting provider automatically records technical data in server log files (in particular IP address, date and time, page accessed, volume of data transferred, browser type/user agent, referrer). This data serves the secure and stable operation, error analysis and prevention of misuse (e.g. limiting excessive requests). The website is hosted with Microsoft Azure in data centres in Switzerland. An IP address may be processed for approximate location assignment and security logging.
3. Cookies and consent
We use cookies and comparable technologies. Strictly necessary cookies (e.g. for language and theme settings and for consent management) are required for operation. Services requiring consent (statistics, marketing, maps) are only loaded after your approval via our consent tool (Klaro). You can withdraw or adjust your consent at any time via the cookie settings.
4. Contact form and e-mail
If you contact us via the contact form or by e-mail, we process the data you provide (in particular name, e-mail address, telephone number and your message) in order to handle your enquiry and prepare a quote. This data is not used for other purposes without your consent.
5. Google Analytics (GA4)
With your consent (statistics), we use Google Analytics 4 (measurement ID G-YBPPBK7W8T) provided by Google Ireland Limited for reach measurement and to improve our offering. Cookies are set and usage data (e.g. truncated IP address, device and browser information, pages visited) is processed. Google Analytics is not loaded without consent.
6. Google Ads
With your consent (marketing), we use the Google Ads tag (ID AW-974459701) to measure the effectiveness of advertising. The tag is not loaded without consent.
7. Google Maps
To display our service area, we embed Google Maps with your consent. When the map loads, data (including your IP address) is transmitted to Google. No map is loaded without consent.
8. Fonts (Google Fonts)
For a consistent appearance, fonts are loaded from Google servers (Google Fonts). Your IP address is transmitted to Google in the process. We endeavour to limit such transfers to what is necessary.
9. Google reviews
We display reviews from our Google business profile on our website. These are retrieved server-side via a Google interface and cached; no personal data of website visitors is transmitted to Google in the process.
10. Disclosure to third parties and transfer abroad
To provide our services, we use carefully selected service providers (in particular Microsoft for hosting and Google for analytics, advertising and map services). Data may be transferred to countries outside Switzerland or the EEA – in particular to the USA. We base such transfers on appropriate safeguards (e.g. standard contractual clauses).
11. Retention and deletion
We process personal data only for as long as is necessary for the stated purposes or due to statutory retention obligations. The data is then deleted or anonymised.
12. Your rights
Within the scope of applicable law, you have the right to information, rectification, erasure and restriction of processing, to object to processing and to data portability. You may withdraw any consent given at any time with effect for the future. To do so, please contact the address stated above.
13. Right to complain and changes
You have the right to lodge a complaint with a supervisory authority – in Switzerland with the Federal Data Protection and Information Commissioner (FDPIC). We may amend this privacy policy at any time; the version published on the website at the relevant time applies.
Umsetzung dieser Webseite
Diese Website ist eine moderne, mehrsprachige Webanwendung aus einer Codebasis. Hier ein Überblick über die wichtigsten technischen Bausteine.
Architektur & Stack
- .NET 10 (neueste .NET-Generation) mit C# 14 – durchgehend auf dem aktuellen Stand, ohne veraltete Abhängigkeiten.
- Blazor Web App – server-seitiges Rendering mit interaktiven Komponenten.
- Enhanced Navigation für schnelle Seitenwechsel ohne vollständigen Reload.
- Eine Codebasis bedient alle Auftritte: die Länder-Domains .ch / .de / .com und die Schweizer Sprach-Subdomains
fr./it.swisskaraoke.ch. - Saubere, modulare Architektur mit klarer Trennung von Infrastruktur und Features.
Mehrsprachigkeit
- Neun vollständig übersetzte Sprachen: Deutsch, Englisch, Französisch, Italienisch, Spanisch, Portugiesisch, Albanisch, Thai und Filipino.
- Im Sprachumschalter in 14 regionalen Varianten wählbar – Schweizer Varianten de-CH / fr-CH / it-CH, dazu de-DE, fr-FR, it-IT, en-GB / en-IE / en-US, es-ES, pt-PT, sq-AL, th und fil-PH.
- Fünf indexierte Regionalvarianten mit eigener Adresse & hreflang (de-CH, de-DE, fr-CH, it-CH, en-GB) – über die Länder-Domains .ch / .de / .com plus Schweizer Sprach-Subdomains (
fr./it.swisskaraoke.ch). - Die Markendomains .fr und .it leiten per 301 auf die passende Schweizer Sprachvariante – bewusste Konsolidierung der Suchmaschinen-Signale statt Duplicate Content über fast gleiche Seiten.
- Automatische Sprachwahl anhand der Domain; manuelle Umschaltung jederzeit möglich.
- resx-basierte Übersetzungsinfrastruktur, vorbereitet für weitere Sprachen und Regionen.
SEO / Google Search
- hreflang für alle Domains inklusive
x-default– saubere internationale Indexierung. - Korrekte Canonical-Tags (kein Duplicate Content).
- Schema.org-Daten, server-seitig gerendert (eine Quelle der Wahrheit):
- LocalBusiness (Standort, Einzugsgebiet, Preisspanne, Öffnungszeiten).
- FAQPage für Rich Snippets.
- AggregateRating dynamisch aus echten Google-Bewertungen.
- Einzigartige Meta-Titel, -Beschreibungen und Open-Graph-Tags pro Seite und Sprache.
- Pro Domain passende Sitemap und robots.txt.
- Lokales Karaoke-Bars-Verzeichnis (Übersichts-Hub + Stadtseiten) als Top-of-Funnel-Content – geo- und sprachgesteuert auf die Schweizer Märkte (de-CH / fr-CH / it-CH).
Google-Integrationen (einwilligungsbasiert)
- Google Analytics 4 mit Lead-Erfassung der Kontaktformulare.
- Google Maps als datenschutzfreundliche, erst nach Einwilligung geladene Einbettung.
- Google Reviews live über die Places API – Bewertungen fließen in Anzeige und SEO-Daten.
- Jede Google-Komponente lädt ausschließlich nach expliziter Zustimmung.
Datenschutz
- Cookie-Consent (Klaro), DSGVO-/DSG-konform, mit getrennt steuerbaren Diensten.
- Kontextuelles Blockieren eingebetteter Inhalte bis zur Einwilligung.
- Keine externen CDN-Aufrufe: Schriftarten (Barlow) und Icons lokal ausgeliefert – kein IP-Transfer an Dritte (z. B. Google Fonts).
- Spamschutz der Formulare ohne externes Captcha – datenschutzfreundlich.
Interaktive Features & UX
- Live-Preisrechner mit Gäste-Slider.
- Verfügbarkeits-Check mit direkter Anfrage per WhatsApp oder Formular.
- Animiertes Bewertungs-Laufband (mit nativem Swipe auf Mobilgeräten).
- Dark-/Light-Theme – flackerfrei server-seitig vorgerendert.
- Hero-Video mit robustem mobilem Autoplay.
- WhatsApp-Chat-Widget, animierte Kennzahlen, sanfte Scroll-Effekte, Toast-Benachrichtigungen.
- Durchgängig responsiv auf allen Gerätegrößen.
Barrierefreiheit
- Accessible Names auch für per JavaScript injizierte Elemente (z. B. Cookie-Dialog) – korrekte aria-Labels statt leerer Titel.
- Korrekte ARIA-Rollen (z. B.
role="img"mit Label am Sterne-Rating). - Rücksicht auf
prefers-reduced-motion– Animationen werden reduziert ausgespielt. - Semantisches HTML, sichtbarer Fokus, dekorative Icons konsequent via
aria-hidden.
Formulare
- Kontakt- und Schnellanfrage-Formular mit Validierung und Versandbestätigung.
- Spamschutz ohne externes Captcha: Honeypot-Felder + Mindest-Ausfülldauer.
- Erfolgreiche Anfragen werden – bei erteilter Einwilligung – als Lead-Ereignis erfasst.
Sicherheit & Stabilität
- Security-Response-Header auf allen Antworten: durchgesetzte Content-Security-Policy, HSTS (2 Jahre inkl. Subdomains + Preload), Referrer-Policy, Permissions-Policy, X-Content-Type-Options, Cross-Origin-Opener-Policy.
- CSP-Verstoß-Monitoring: eigener Report-Endpunkt (
/api/csp-report→ Seq) erfasst Policy-Verletzungen für Diagnose und laufende Härtung. - Tech-Stack-Verschleierung:
Server- undX-Powered-By-Header werden entfernt – weniger Angriffsfläche. - Per-IP Rate Limiting (Token Bucket, 429) – statische Assets und Blazor SignalR sind ausgenommen.
- Echte Client-IP hinter dem Edge: Die Besucher-IP wird zentral aus den Front-Door-Headern (
X-Azure-ClientIP, FallbackX-Forwarded-For) statt aus der Proxy-Adresse ermittelt – so greifen Rate-Limiting, Geo-Zuordnung, Request-Logging und Lead-Herkunft pro echtem Besucher statt pro Edge-Knoten. - Origin-Absicherung hinter Front Door: Die App-Server nehmen ausschliesslich Traffic vom eigenen Front Door an – geprüft über Azure-Service-Tag und die eindeutige
X-Azure-FDID-Kennung. Direktzugriffe am Edge vorbei werden mit 403 blockiert; damit ist die vertrauenswürdige Header-Kette (echte Client-IP, Protokoll) nicht fälschbar und das Rate-Limiting nicht umgehbar. - HTTP Resilience (Retry + Circuit Breaker) für alle externen HTTP-Clients (Google Places API, IP-Service, E-Mail-Service) via
Microsoft.Extensions.Http.Resilience. - Fail-Fast DI: Startup-Fehler brechen den Start sichtbar ab statt still zu verschlucken.
- Bootstrap-Logger fängt Exceptions vor dem vollständigen Logger ab – auf Azure im Log Stream sichtbar.
- Kein externes Mapping-Framework: Formular-Daten werden ohne AutoMapper-Abhängigkeit direkt gemappt.
- Automatisierte Tests (Unit-Tests) für SEO-Metadaten, Schema.org, Domain-Sprachzuordnung, Request-Logging, IP-Validierung und Client-IP-Ermittlung hinter Front Door.
- Kontinuierliche Qualitätssicherung: statische Code-Analyse mit ReSharper und SonarQube Cloud (Quality Gates in der CI-Pipeline).
Hosting, Performance & Betrieb
- Gehostet auf Microsoft Azure; jede Domain läuft über eine eigene Azure-DNS-Zone und ein eigenes Azure-Front-Door-Profil – mit verwaltetem, automatisch erneuertem TLS-Zertifikat und globalem Edge-/CDN-Layer (Routing, TLS-Terminierung, DDoS-Schutz an der Edge).
- Weiterleitungen laufen an der Edge, nicht in der Anwendung: Apex auf
www(308) bei den Inhalts-Domains, 301 auf die Schweizer Sprachvariante bei .fr/.it – der Ursprungsserver wird dafür gar nicht erst angefragt. - Asset-Fingerprinting sowie gebündelte, minifizierte CSS/JS (via esbuild) – kein veraltetes BuildBundlerMinifier.
- Schlanke, lokal ausgelieferte Frontend-Assets: nur eine Icon-Library (Bootstrap Icons) und Schriftarten (Barlow) selbst gehostet – keine externen CDN-Aufrufe (besser für Datenschutz und LCP).
- MapStaticAssets (.NET 9+) mit automatischem Brotli/Gzip und ETag-Caching.
- Caching von Bewertungen und wiederkehrenden Daten (IMemoryCache mit Sliding + Absolute Expiration).
- Lazy-Loading und komprimiertes Hero-Video (MP4 + WebM).
- Core-Web-Vitals-Optimierung: LCP-Bild mit
fetchpriority="high"vorgeladen (nur Startseite), below-fold lazy geladen; feste Bildmaße verhindern Layout-Shift (CLS). - Strukturiertes Logging (Serilog → Seq) und Telemetrie (Azure Monitor OpenTelemetry Distro) – Microsofts strategische Richtung, kein klassisches App-Insights-SDK.
- Request Logging Middleware erfasst jeden HTTP-Request inkl. Scanner-Probes (Status-Code, Client-IP, User-Agent) – schliesst den Blind-Spot von rein page-basiertem Logging.
- Automatisiertes CI/CD-Deployment über Azure DevOps.
